A filing cabinet drawer stuck closed is almost always a jammed locking bar, a misaligned drawer, or something caught inside; here’s how to find and fix it.
For the full breakdown, see our best 3 Drawer Filing Cabinet guide.
One drawer locked tight while the key turns freely. The causes are mechanical, not mysterious: a partially jammed locking bar, a cabinet sitting off-level, or papers catching as the drawer tries to leave its track. The fix for a filing cabinet drawer stuck closed starts with understanding which of those three is the real culprit, then working through them in order.
Before Anything Else: The Basic Checks
Rule out the easy stuff first. Confirm the drawer is actually unlocked — a key that turns 45 degrees and stops doesn’t always mean the lock mechanism disengaged. Then push every other drawer fully closed; interlock systems physically block one drawer when another sits even slightly open, and that single open drawer can make a different one refuse to budge. If a neighbor drawer rides up even a quarter-inch, the interlock catches and locks the whole column.
Check the cabinet’s stance.
Freeing a Jammed Locking Bar
The most common mechanical failure is a locking bar that’s partially stuck. When the key turns but the drawer stays shut, the bar hasn’t dropped fully out of its catch.
If it doesn’t, it’s bent or blocked, and you’ll need to remove all drawers to inspect the bar directly.
When Something Is Physically Caught
Not every stuck drawer is a lock problem.
A cabinet that is overloaded on one side also causes binding. Heavy contents shift the drawer body, pressing it against the frame; even out the load and retry.

When the Lock Itself Is Jammed
If the key won’t turn at all, or the locking bar moves freely but the drawer still won’t open, the lock mechanism itself is seized. That’s the point to stop forcing it.
A note on safety: don’t defeat the locking mechanism. The interlock system exists so that opening two drawers at once can’t tip the cabinet forward; disabling it creates a real stability hazard. Restore the mechanism to working order rather than bypassing it.
