I fitted new batteries to my keyless entry fob and found it did not work. Discovered that it has to be re-programmed. How to do this and can I do it myself?

 

YES - you can do it yourself.

Remote fobs should only need reprogramming if:

1. you take too long to change the batteries, or
2. press any of the buttons whilst you are changing batteries

Reprogramming instructions are in the FAQ's at the top of the threads:

Note that if you have more than one remote fob, they must ALL be reprogrammed together.
