Remote Key Fob Repairs
If your remote key fob isn't working, the first thing to do is to check the battery. This is the most typical reason for your car not responding when you make commands.

Check the Battery

A remote key fob sends an RF signal (RF) to the vehicle's receiver. When you press the button on the key fob it sends a unique signal that is compatible with preprogrammed codes in your vehicle's computer system.

If you're having trouble with your key fob, it could simply need an upgrade in the battery or the codes might need to be reset.
