I dug my spare key out last week when I was going to get the Highline clocks fitted and none of the buttons were working on it. I swapped the battery over with 1 that was OK as I assumed it had died after sitting for so long, but to no avail.
I haven't used it since I bought the car, so dear knows how long its been faulty for. I tried the key and it still works for starting the car at least.
Any idea what could be wrong with the remote side of it?
