I have a Vauxhall Corsa C 1.0L 2002 and when I bought the car 2 years ago, the guy I bought it from told me that the remote central locking didn't work but probably just needed a new battery. I've tried numerous time to try and fix it over the past two years but to no avail. I've tried two new batteries, then bought a new section of the key that consists of the lock/unlock buttons but it never works when I turn on the ignition and try pressing down on either button whilst the cars in sync mode. I just use the key in the drivers door to unlock the car, and all doors unlock so that all works okay.
I've looked inside the key and I can still see the chip in it.
Any ideas on how to fix the situation? After two years I would like to finally be able to use the remote central locking! I had to get the code for my radio a while back from vauxhall and they also supplied me with other codes such a the key code, immobilize coder etc.
Any help would be greatly appreciated!
