Electronic car keys, often known as key fobs, can be used to operate your vehicle’s doors, trunk, alarm, and even start it remotely from a distance.
These key fobs can eventually malfunction, just like any other electronic equipment, usually as a result of signal loss. However, you can still use the remote in this situation by just reprogramming it yourself.
This article will walk you through the process of programming your automobile key fob so you don’t have to take it to a mechanic and spend your hard-earned money on it.

How do I find out which battery my key fob uses?
Open your fob to find the battery your automobile key fob uses. There will probably be an engraving that starts with CR followed by a string of digits if the item contains a battery. Check your owner’s manual or search online for your car’s make, model, and year without a battery or engraving.

This may also occur if your keys fall into water or if another accident occurs. Key fobs can be repaired and reprogrammed, but if the damage is too severe, they could need to be replaced.

- Press the lock button on your fob after the fifteenth button press. The car doors will lock and the fob will be fully functional if the pairing process was completed. If the attempt failed, it could be worthwhile to try it again to determine if there was a mistake in the first attempt. The timing of this strategy can be a little tricky and challenging to master the first time.
