Car Key Fob Repairs
Today's key fobs can do more than unlock and start cars. But that extra complexity can cause costly repairs if one of them breaks.
It's important to know that a majority of fobs are powered by flat watch-style batteries, that can be replaced at home. You may even find that a reset can bring it back to life.
Battery Replacement
A dead battery is the main reason for a key fob that isn't working. This is easy to fix, and it's worth a try before you spend money on a new fob. Simply drive your car to an auto parts store or a hardware retailer that stocks button cell batteries and pick up an alternative. You can also refer to the owner's manual (or, if you don't have one, YouTube is full of videos from people who show you how to do it) for specific instructions for opening and replacing the battery in the specific type of fob you have.
Most fobs come with two halves that snap together- you'll need to gently break the sides in order to access the battery. You'll need a small, flat-bladed screwdriver, or a different tool with a small blade. You can wedge your tool into a notch at the bottom of the key fob. It is also advisable to be on the lookout for small pieces that could be loosened while working.

Replace the internal key

A simple screwdriver is enough to accomplish the task, but some fobs have complicated release mechanisms that require a special tool or specialized equipment that is available only at a dealership. It's best to have a qualified mechanic handle this job to ensure you don't accidentally break the fob or hurt yourself.

Then, press the lock button on the fob while looking at the transmission receiver, which is usually located in the front of the vehicle above the mirror. Within a brief time the key will announce to the vehicle that it's being programmed by triggering the doors' locks or emitting the sound of a chime. This procedure can be difficult, so it's important to be attentive to the timing and to not over-press the key button.
