My buttons on my Fob stopped working so i popped in to my local Vauxhall dealers to get a new battery , and the guy said looks like its the fob, as with a new battery the LED does not light up ,
he quoted 80 quid for a new one,
i have seen em on ebay from 5-15 quid, how easy it it to reprogram them, i know the ford ones its just oress a few buttons and turn the ignition on and off a few times?
the thing with vx remotes are the connections on the small circuit board are known for breaking or the solder joints comin loose, id be having a look at those first, try taking the board out of the remote and squeezing the battery holder onto the board and press the buttons at the same time, i think you will find this will work, then to reprogramme the lock/unlock function of the remote put the key in the ignition and turn the ignition on and press the lock and unlock buttons a few times, that will re-programme the remote into your car!
