The Dorman is the closest thing to a dealership fob you can program in your own driveway.

This is the pick for anyone who wants to skip the locksmith entirely. The Dorman 99154 comes with its own patented programmer that plugs into your OBD2 port (a standard diagnostic port under your dashboard), letting you sync the new fob yourself without any additional equipment beyond the included programmer and a working original key. It has 5 buttons — lock, open up, remote start, power liftgate (a powered rear hatch), and panic — matching the full feature set of the original fob on compatible GM and Suburban models from 2011 onwards. One buyer on a 2011 Suburban reported programming three fobs in under two minutes each, though they noted the programmer plug needs to be inserted upside down on some vehicles, which the paper directions cover.

The trade-off? This is a single-fob package, and reviewers wished a second remote came in the box. You also must have at least one working original key or fob to kick off the programming process. If your original fob is completely dead, this kit cannot help you start fresh. The build feels solid — one long-term user called the hard plastic housing durable — but the lithium-ion battery needs replacing eventually, and the programmer only works for three programming sessions total.

A two-fob kit with an OBD2 programmer that one buyer called a true money-saver against dealership quotes.

This Nrgedzam kit is built for Chevrolet Silverado 1500/2500/3500 (2014-2018), GMC Sierra (2014-2018), and Chevrolet Colorado plus GMC Canyon (2015-2021) owners. It comes with two fobs, each with 4 buttons: lock, open up, remote start, and alarm/panic. A notable advantage here is the maximum range of 50 meters (about 164 feet) — noticeably longer than the typical dealership fob, so you can start your truck from across a parking lot. The included OBD2 programmer makes it a quick two-minute job: turn the key to ON, plug in the programmer, hold lock+open up on the fob until you hear a beep. Reviewers consistently mention the pads feel slightly sensitive, meaning you might trigger a button accidentally if the fob is loose in your pocket.

One buyer on a 2016 Chevy Colorado LT confirmed all four functions — lock, open up, alarm, and remote start — work perfectly, and they saved between and compared to dealership pricing. A minor pair of compromises: the fobs use a silver frame that some buyers felt looked less premium than the original black, and the warranty description on the listing simply says “NO,” so any defect means a return to Amazon rather than a manufacturer warranty claim.

A 5-button two-pack that saves Jeep and Dodge owners from buying a single expensive dealer fob, though programming still costs extra.

The SUPALAND replacement hits the balance for 2017-2022 Jeep Grand Cherokee and Dodge Durango owners with push-button start. It offers 5 buttons — lock, open up, remote start, panic, and a power liftgate (a powered rear hatch) button — matching the layout of the original 68143505AC and 68150061 part numbers. Each fob comes pre-installed with a battery and electronics, so they are ready to program. The big distinction here is that these fobs require a locksmith or dealership to program; there is no DIY OBD2 tool included. One reviewer synced them to a 2017 Jeep Grand Cherokee Trailhawk using a third-party OBDLinkMX+ and JScan app, but that requires buying extra hardware.

Customers note mixed consistency with the batch. One owner noted they “was able to pair instantly but one of the remotes the battery was dead,” which is frustrating in a two-pack. Another said the remote start button needed four presses instead of two to activate, which suggests the button sensitivity or programming calibration is not as tight as an OEM fob. On the plus side, the plastic build quality earned positive marks — several reviewers described it as “very nice” and “quality,” even if it is not an original Mopar part. At just 40 grams (1.4 ounces) per fob, it feels light in your pocket.

An affordable single fob for 2014-2019 Jeep Cherokee — but be prepared to pay a pro to program it.

This Beefunny fob is the lowest-cost entry point in the lineup, built specifically for Jeep Cherokee models from 2014 to 2019 with push-button ignition. It has 4 buttons — lock, open up, remote engine start, and panic — and runs on a CR2032 battery (the common coin-cell battery found in most key fobs). The fob uses the 433MHz frequency (a radio band standard for key fobs) and carries FCC ID GQ4-54T, which matches the OEM part number 68141580AC. One buyer called it “great value,” noting the dealership wanted for the same thing. But the catch is clear: you must have a professional auto locksmith or dealership program and cut the key, which one reviewer noted cost extra.

Shoppers say some reliability concerns. One owner described how the fob “somehow unprogrammed itself and only starts car and not open up the doors,” which undermines the whole purpose of having remote start. Another reviewer mentioned you cannot program Jeep fobs without extra equipment — an important warning for anyone hoping to DIY this at home. The plastic build feels solid according to some, but the programming instability means this is best treated as a low-risk spare rather than your everyday key. If you are willing to pay the to programming fee and want a backup to your original, the savings still work out — but only if the fob stays programmed.
