Key Fob Not Working After a Battery Change? What to Check

If your key fob has stopped working, the most common cause is a dead fob battery, followed by worn buttons or a fob that needs reprogramming. The good news is that many of these are quick fixes, and some you can sort out yourself.

Start with the fob battery

A weak or dead coin-cell battery inside the fob is the number one reason buttons stop responding. If you have a spare fob, try it. If the spare works fine, your first fob almost certainly just needs a fresh battery. These are inexpensive coin cells you can pick up at most stores, and swapping one in is usually a five-minute job.

After you changed the fob battery

If the fob stopped working right after a new battery went in, the cause is usually in the swap itself rather than the fob.

The battery is in upside down; check which side faces up against the old one or the marking inside the case
It is the wrong cell: coin cells that look alike can differ in thickness and not touch the contacts properly
A contact got bent or dirty, or the two halves of the case did not snap fully closed
The rubber button pad or the circuit board shifted when the case was put back together
The new cell is weak straight out of the package, which happens with old stock

A few vehicles also want the remote re-synced after its battery has been out; your owner's manual says if yours does. If none of these bring it back, the fob may have been damaged or lost its programming.

After the car battery was replaced

On most cars the fob keeps working after a car battery swap. If yours stopped, check the basics first: the battery terminals are tight and clean, and the new battery is properly charged, because a weak car battery can stop the car from confirming the fob's signal. Some vehicles need a short relearn or reset after their power has been cut, and the owner's manual covers it. If the car still won't recognize the fob, it may need reprogramming, which I do at the car.

Other common causes

If a new battery doesn't bring it back to life, here are the usual culprits I see around Winnipeg.

Worn or sticky buttons from years of daily use
Water damage or a fob that took a hard drop
Lost sync between the fob and the vehicle, which can need reprogramming
Interference near the vehicle from other electronics
A vehicle battery that's too weak to confirm the signal

Locks but won't unlock

When the fob locks the car but won't unlock it, look at the button and the doors before the battery.

The unlock button is worn: the button you press most wears out first, so one can fail while the others still work
Many cars unlock only the driver's door on the first press and the rest on a second press, which can look like a fault
If some doors unlock and others don't, the fob is sending fine and a door lock actuator in the car is the likely suspect, which is a repair-shop job rather than a key job

Don't forget the manual key

Most fobs hide a small metal key blade inside, or your vehicle has a hidden keyhole on the driver's door. If the fob is unresponsive, you can usually still unlock the door by hand and get inside while you sort out the fob itself.

When it's a programming or transponder issue

If the buttons work but the car won't recognize the key, or the fob simply won't pair again, you may be looking at key fob or transponder programming. That starts from $160, or $170 for a smart push-to-start fob, all-in; tell me your year, make and model and I'll confirm the exact price. I work on most makes and models, older cars included.
