| MINI Alarm The immobalizer in VAG products (VW/Audi) and several other makes use a small chip inbedded in the key which communicates with a transponder in the dash. When an attempt is made to start the car, these communicate to validate that the key being used is registered for that car. If not, the car starts briefly, but cuts out and won't start again until one of the correctly coded keys are used to start the car. I hope this makes sense. |
