I have an S reg MK4 VW Golf, one of the first to be registered.
I am wondering about the battery in the ignition key used for locking and setting the alarm. I think the operational range between me and the car is reducing which might point to the battery going flat. The key is one where you press a button and the key swings out from the side of the fob.
Is the key easy to open and can I replace the battery myself? Will any of the codes be lost if I do this?
Thanks for any info.
