This guide will tell you how to reprogramme vauxhall remote central locking keys for free which some people are selling on ebay!
I must point out that if you have purchased a new key for your car ,then you MUST have the key programmed to the vehicle by vauxhall, you are wasting your money buying guides off ebay as the keys have to be programmed to the vehicle using specialist software.
1. Switch on ignition: the vehicle will then stay in synchronizing mode for 30 seconds
2. Briefly press the lock or unlock button on the remote control with the key still in the ignition
3. The central locking will now lock then unlock to show the remote control is now synchronized
Thats all there is to it.
