Sup everyone. I'm having problems with my remote keys and central locking. First of all I have to manually unlocky car then the alarm triggers off and I have to switch on the engine to stop it.

In the middle near the handbrake is a unlock and lock button. Car locks fine but when i press the unlock it doesn't work. However if I pull the battery out of the car for 10 mins and put it back in it works for a little while and goes back to the same problem.

I've tried syncing my keys with the valet key and change the battery in both my spare key and main key but still doesn't unlock or lock.

Any suggestions to fix this pls?

Thanks
