An alarm that only screams after your car is already broken into is useless. A remote start that only works from your driveway defeats the whole purpose. The best systems combine a siren loud enough to scare off a thief and a remote that reaches from inside your house or office. The EASYGUARD EC201-M9 (800-meter range, two-way LCD pager) gives you the most usable range and real-time feedback for the best value. But if you want a color screen and phone-based control, the Viper 5906V (1-mile range, USB-rechargeable remote) is your pick. This guide breaks down the real specs, what buyers actually report, and which trade-offs matter for your car.
I’m Min — the founder and writer behind Gadgets Feed. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.

How To Choose The Best Alarm And Remote Start
Every Alarm And Remote Start system has to balance three things: how far away it works, how loud it screams, and how much wiring you need to do. Most buyers figure out their priorities once they realize that a 15-meter range with a 125-decibel siren is a different beast from a 1-mile range with a 2-way LCD remote. Here is what to look for before you buy.
Range: Open Field vs Real World
Manufacturers advertise range in “open space,” which means a big empty field with no interference. In real life, parking lots full of metal cars, concrete walls, and buildings cut that range down by a lot. A system rated at 800 meters in the open might start your car from about 200-300 meters in a suburban neighborhood. A system with a 15-meter range works only in your driveway or garage — useful, but not for anyone parking on the street. Always check if the remote has a two-way confirmation (it beeps or shows a message when the car actually responds) so you know the command went through.
Two-Way vs One-Way Remotes
A one-way remote sends a signal and hopes the car received it. A two-way remote gets a confirmation signal back from the car, showing you on an LCD screen or with a beep that the engine is running, the doors are locked, or the alarm triggered. Two-way systems cost more but save you the walk of shame to a car that never actually started. LCD screens show additional info like interior temperature, battery voltage, and which zone triggered the alarm.
Siren Loudness and Alarm Sensors
Siren output is measured in decibels (dB). A 120 dB siren is very loud and will attract attention in a parking lot. A 125 dB siren is noticeably louder — a 5 dB jump is about a 4% increase in actual sound pressure but sounds significantly more aggressive to human ears. Beyond volume, look for a shock sensor (detects impacts and bumps), a door trigger, and an ACC detection circuit (alarms when someone turns on the ignition without the remote). Some systems let you connect to your car’s existing horn instead of adding a separate siren, which saves installation space.
Push-to-Start and Keyless Go Features
Many modern systems swap your old key cylinder for a push button start. This is convenient but adds complexity: the system must detect when the brake is pressed, when the key fob is present, and when the engine is already running. Some cheaper systems have trouble with the auto-lock timing or the brake-sensing circuit. Make sure the push button includes an auto-lock feature (locks the push button 30 seconds after the engine stops so nobody can drive off without the remote).
Installation Difficulty — Be Honest With Yourself
Every single verified review across these products repeats the same warning: installation requires automotive electrical knowledge, a multimeter, and often 12-24 hours for a clean install with all features working. Systems with a simple plug-and-play design are rare. If you cannot identify which wire is the 12V constant, the starter wire, the ignition wire, and the accessory wire in your car’s steering column, budget for professional installation. A bad DIY install can drain your battery, fail to start the car, or cause the alarm to false-trigger at 3 AM.

In‑Depth Reviews
1. EASYGUARD EC201-M9 2 Way Car Alarm System
Its 800-meter range is the longest in this roundup, and the two-way LCD pager lets you see the car’s status from across the parking lot — a huge upgrade over the 15-meter BANVIE ST807.
If your main frustration is walking outside only to find your car never started, this system solves that with a 1.73-inch LCD pager on the remote that shows you real-time feedback — door status, vibration triggers, battery voltage, and engine run time. The advertised range is 800 meters in open space (and buyers report good range in real-world suburban settings), which is a huge gap compared to the 15-meter range on budget models like the BANVIE ST807. The two-way pager lets you monitor your vehicle 24 hours a day, so you see an alert the moment someone bumps or opens the car.
Buyers confirm the system delivers on the basics: bright LED on the remote, loud siren, and quick customer service. The catch is installation. Reviewers caution that the Chinese-to-English wiring diagram is poor and wire labels can be confusing (on some units the ON1 and ON2 labels are reversed). This is absolutely not a DIY system for beginners. An extra bypass module (available separately) is required for vehicles with a factory chip immobilizer, so factor that into your total cost and planning.
Two-Way Confidence
- 800-meter range is the longest in this roundup
- 1.73-inch LCD pager shows battery, door/vibration triggers, and run time
- Remote engine start with turbo timer mode to cool the turbo before shutdown
Real Talk
- Requires professional install — wiring labels may be reversed
- Not compatible with diesel vehicles without extra timer switch
- Additional bypass module needed for factory chip-immobilizer cars
Reach for this if: you want the most usable range and a pager that shows you what is happening with your car in real time.
Look elsewhere if: you are not comfortable reading a confusing wiring diagram or paying for pro installation plus a bypass module.
2. Viper 5906V Color Remote Start & Security
A color LCD remote that shows you interior temperature and door status, plus a USB rechargeable battery — neither the EASYGUARD nor the Avital offer that.
The Viper 5906V comes with a color LED remote that shows you interior temperature, door status, and alarm sensor status on a small screen, which feels closer to a smartphone than a standard fob. The advertised range is 1 mile in open space, though owners mention real-world range is less with obstacles. One reviewer who has used the system for three years highlights the Smart Start compatibility, which lets you lock, open up, and start the car from your phone anywhere with cellular service. The remote is USB rechargeable, so you never buy coin batteries again.
Customers note the sensitive remote buttons cause accidental presses, but the button lock feature solves that. Manual transmission owners face a complex start sequence that can be broken by opening a door — a known quirk. The system works well with additional Viper sensors like motion, glass break, and tilt detectors. Buyers in Texas heat praise the remote start, and reviewers love the vibration mode on the remote so they feel alerts without beeping. Two-car operation is built in, so one remote controls two vehicles.
Top-Shelf Features
- Color LCD remote with interior temp and door status display
- USB rechargeable remote — no battery replacements needed
- Smart Start app compatibility for smartphone control
Premium Caveats
- Buttons are sensitive — accidental presses happen without the lock feature
- Manual transmission start sequence is picky about door opening
- Real-world range shorter than 1 mile with obstacles between remote and car
Grab it for: the color screen, phone-based Smart Start, and ability to pair with additional motion/glass/tilt sensors.
Consider alternatives if: you drive a manual car or want the simplest possible setup without extra sensors.
3. Avital 5303L Car Alarm Remote Start and Keyless Entry
It features a Stinger Double-Guard Shock Sensor with a two-stage Warn-Away (a light tap warns, a hard hit alarms) — more nuanced than the basic shock sensor on the BANVIE kits.
Avital built the 5303L around security rather than just convenience, which means you get a Stinger Double-Guard Shock Sensor with a Warn-Away (a two-stage sensor that gives a light warning on a light tap and a full alarm on a hard hit), multi-level security arming (choose which inputs and sensors are active), and a Fail-Safe starter kill (the engine cannot start without the remote disarming the system). It comes with two remotes: one two-way LCD remote that confirms your commands and a one-way 4-button backup remote. Four AUX outputs let you add accessories like trunk pop, window roll-up, or garage door integration.
Buyers are emphatic about one thing: this is not a beginner install. Reviewers report it took 24-plus hours of work across two weeks for a clean installation, requiring wiring diagrams and automotive electrical knowledge. The two-way LCD remote drains batteries faster than expected, and the beep volume is low. An extra bypass module (not included) is needed for many vehicles with chip immobilizers. That said, buyers who have had the system for ten years report it still works perfectly. One reviewer notes excellent range — the remote works from the fourth floor of a building across the parking lot.
Security Depth
- Stinger Double-Guard shock sensor with two-stage Warn-Away
- Four AUX outputs for trunk, windows, and other accessories
- Multi-level arming — choose which sensors are active
Installation Hurdle
- Requires extensive electrical knowledge and 24+ hours for a clean install
- Separate bypass module needed for chip-immobilized vehicles (not included)
- LCD remote drains batteries faster and has a quiet beep
This is for: experienced installers who want a reliable, fully-featured security system with accessory integration.
Not for: anyone looking for a quick weekend project or entry-level car security — this one demands serious skill.
4. Prestige APS997Z Two-Way LCD Confirming Remote Start & Alarm 1-Mile Range
The Prestige system gives you a confirming two-way remote with a 1-mile range and a 120 dB siren at a mid-range price.
This system uses a two-way LCD remote that confirms commands by beeping or vibrating, so you know your car started without walking over to check. The 1-mile range is competitive with the Viper 5906V at this price tier, and buyers confirm they have started their car from about three blocks away in real-world conditions. The siren hits 120 decibels, which is loud enough to draw attention in a parking lot but slightly quieter than the 125-decibel BANVIE ST807.
Buyers who installed this on an older IS300 Lexus found the factory lock/open up integration complex enough that they had to source a better manual online. The main remote feels flimsy to some, and the system outputs are limited to 200mA, which means you may need extra relays (up to 4) and diodes (up to 3) to drive certain accessories. On the plus side, no battery drain or false alarms were reported, and Prestige tech support was excellent according to one reviewer. A Flashlogic programmer may be needed for some advanced options. The push button start setup works well.
Real-World Performance
- Two-way LCD remote confirms start/lock at 1-mile range
- 120 dB siren — loud enough for parking lot attention
- Reviewers point out reliable operation with no battery drain or false alarms
Installation Complexity
- Factory lock/open up integration may require improvising on some cars
- 200mA outputs mean you may need 4 extra relays and 3 diodes
- Main remote feels flimsy to some reviewers
Go for this: if you want a well-supported mid-range system with confirming range and a loud siren without paying Viper-level prices.
Skip it: if you need strong accessory outputs or a more durable feeling remote in your hand.
5. BANVIE 3-in-1 Car Keyless Entry Security Alarm System (806-FT4-NS)
An entry-level three-in-one kit that swaps your key cylinder for a push button start.
This BANVIE kit bundles keyless entry (lock/open up/trunk), a one-way alarm with a shock sensor, remote engine start, and a push-to-start button into one package. The siren output is optional — you can connect the system to your existing car horn or add a separate siren. The push button includes an auto-lock feature that locks the button 30 seconds after the engine stops, so nobody can drive away without your remote. The alarm triggers for 8 seconds on shock and 25 seconds on door opening or brake press.
Shoppers say that the system works well when set up correctly — one reviewer has bought three different BANVIE units and calls them “great quality, dependable.” The remotes have excellent battery life according to that same buyer. However, one long-term owner found a bad solder spot on the circuit board after a year of use, which they had to repair with a soldering iron. The instructions are easy to follow, but the reviewer adds a clear warning: if you are not comfortable with vehicle wiring, pay a professional. This is a third 2.09-pound system, matching the Prestige.
Starter Value
- All-in-one kit: lock/open up, alarm, remote start, and push button
- Siren output is optional — route to your car horn or add a separate siren
- Push button auto-locks 30 seconds after engine stops for security
Entry-Level Limits
- One-way remote gives no confirmation — you hope the car responds
- One reviewer found a circuit board fault after one year
- Range is not specified and likely short; not for long-distance starts
Good for: someone who wants a basic push button start and keyless entry on a small budget and is comfortable with wiring.
Not for: buyers who need to start from far away or want two-way confirmation that the car actually fired up.
6. BANVIE 3-in-1 Car Keyless Entry Security Alarm System (ST806-BQ)
The same three-in-one recipe as its sibling but with a slightly lower price and mixed reliability reports.
Functionally very similar to the other BANVIE kit, this version includes remote door lock/open up/trunk release, a shock sensor alarm, engine start/stop (only when the system is armed and the handbrake is engaged — a safety feature), a 15-minute warm-up timer, and auto central locking when you start driving. The push button start replaces your key cylinder. The siren signal output can be set to positive (for an extra siren) or negative (for your car’s existing horn). If you install a window closer module, the system can roll up your windows automatically when you arm the alarm.
Buyers have had mixed experiences. One reviewer says it works perfectly on a 2004 Mustang with the alarm hooked to the horn, and the remote start works flawlessly. Another buyer warns that the instructions are confusing and “fubar” — after initial use, their car would not fully turn off, with the dash and three warning lights staying on and draining the battery in two to three days. One reviewer found the range poor and the push button fell into the steering column. A professional install is strongly recommended unless you have automotive wiring experience and a good multimeter.
Kit Highlights
- Auto-lock when driving and auto window closing (with optional module)
- Remote warm-up timer set at 15 minutes
- Siren signal output supports both positive and negative switching
Quality Concerns
- Buyers report the car may not fully turn off, draining the battery in 2-3 days
- Poor range according to some users
- Push button button fell into the column for one reviewer
Consider this: at a similar price to the other BANVIE kit if you plan on a careful, professional install and want auto window closing.
Look elsewhere: if you want something that works reliably from the start — the reported wiring issues and battery drain risk are real.
7. BANVIE Car Alarm System with Remote Start kit & Push to Engine Start Stop Button (ST807)
Its 125 dB siren is the loudest in this roundup — noticeably more aggressive than the Prestige’s 120 dB — but the 15-meter range limits it to driveway use only.
That extra decibel level makes the siren noticeably more aggressive. The short 15-meter range (about 50 feet) means you need to be close to the car, but this is the same limited range as other budget systems in this class. The system covers basic security: shock sensor alarm, side door alarm, ACC detecting alarm, and auto door locking when you drive off.
Buyers confirm the system is easy to install and “very loud.” One reviewer on a 1966 Chevy C10 liked the simple approach. However, the auto-lock feature does not always work consistently — one reviewer noted it “only works sometimes.” The system does not include proximity open up (approach the car and it opens), so keep that expectation in check. A 15-meter range is really only useful for starting your car from the front door of your house if the car is in the driveway, not from inside a living room or upstairs.
Siren Power
- 125 dB siren is the loudest in the lineup — more aggressive than the Prestige’s 120 dB
- Shock sensor, side door, and ACC detecting alarm coverage
- Buyers find it easy to install and very loud
Proximity Limits
- 15-meter range is very short — driveway-only use
- Auto-lock feature is unreliable according to some buyers
- No proximity open up function
Pick this: if you want the most ear-splitting siren for the money and always park close to where you stand.
Avoid: if you need to start the car from inside the house or want consistent auto-locking behavior.
Understanding the Specs
Range: Open Field vs Real World
The range number on the box (like 800 meters or 1 mile) is measured in wide-open space with no obstacles. In a real parking lot full of cars, concrete walls, and buildings, that range will drop significantly — often to a third or less. Systems with a 15-meter range are driveway-only tools. The EASYGUARD EC201-M9 at 800 meters gives you the most headroom for real-world use. Two-way systems (like the EASYGUARD, Viper, and Prestige in this roundup) also send a confirmation signal back to the remote, so you know the car received the command.
Siren Loudness (Decibels)
Decibels measure sound pressure. A 120 dB siren (Prestige APS997Z) is already very loud — it will attract attention across a parking lot. A 125 dB siren (BANVIE ST807) is about 4% more sound pressure but sounds significantly more aggressive to the human ear because decibels are logarithmic. The difference between 120 and 125 dB is noticeable in how quickly someone nearby will cover their ears and move away. If you park in a high-risk area, the extra decibels matter.

Final Thoughts: The Verdict
For most buyers, the alarm and remote start winner is the EASYGUARD EC201-M9 because it gives you the longest usable range (800 meters), a two-way LCD pager for real-time feedback, and remote start with a turbo timer — all at a price well below the premium Viper and Avital options. If you want the full color screen experience with phone-based Smart Start control, grab the Viper 5906V. And for the loudest siren on a shoestring budget, the standout is the BANVIE ST807 at 125 decibels — as long as you park close enough to use that 15-meter range.
