Hi all

Quick question... I suspect that after 20 odd years the battery is reaching the end of its life! You just can't get value for money any more !!!!

So my question is what battery do I need, and the correct process to do it as I have only one fob and don't want to loose use of the car!

Here is the fob:

Many thanks … I assume there is no time limit to do it or potential loss of program?

Many thanks for all the advice… all done very carefully and normal service is resumed! :-)
