Hello folks. I've just tried to unlock my car using the key fob and its not unlocking the car.  I can unclock the car using the key.

I was thinking maybe the battery in the key fob has finally had it. If it is the battery is it an easy fix?

Any suggestions?

battery would be easy & cheap for quality cell if pull old one & match cell number on eBay

As said above the battery would be my first place to start. :)
