Vauxhall Key Fob FAQ
TRADE ONLY TRADE ONLY TRADE ONLY TRADE ONLY
Since 1993 Vauxhall have used a transponder chip system for the immobiliser, this is a small electronic chip in the top of the key. A receiver unit in the vehicle reads the chip in the key and if the correct code is sent to the engine management control box the vehicle will start.
On most Vauxhall's built before 2000, we can copy your working transponder chip. On vehicles after this we need to programme the new chip to the vehicle. To supply a new chipped key after loosing all your keys we need to see your Vauxhall vehicle.
No record of the code in the transponder chip is kept by Vauxhall It is not printed on the vehicle security card or car pass.
The immobiliser/security code on the Vauxhall car pass is not the transponder chip code. This code is for our computer to access the immobiliser on your Vauxhall, and without this code we cannot programme new keys.
If a new transponder key is required after a lost key, the transponder will require specialist diagnostic computers, and the security code found on the car pass.
The remote key fobs also need specialist diagnostic computers to programme them to your vehicle.
If your Vauxhall has a remote key fob fitted it does not mean the vehicle is fitted with an alarm.
The Vauxhall remote key fob use a moving/rolling code system. Every time the key fob is pressed the code changes, this is to prevent copying. If the key fob is pressed many times away from the vehicle it may lose the code, this also happens if the battery is changed in the remote key fob, or the battery on the vehicle. If this happens follow the battery change procedure.
To re-synchronise the key fob after a battery change:
- Put the key in the ignition, turn ignition on
- Press any button on the remote key fob for a few seconds then release
- Turn ignition off and remove key
- Test remote key fob
Note: This method will NOT programme new or used remote key fobs.
Do not press the buttons on your Vauxhall remote key fob away from the vehicle.
If your car pass - security card is lost it can be obtained from any Vauxhall dealer if you produce your Vauxhall's log book V5, a charge will be made usually £15 to £20.
The Vauxhall immobiliser system is very reliable, if your Vauxhall will not start do not instantly blame the immobiliser, check the vehicle battery and fuses first.
