A transponder key must communicate with the vehicle immobiliser. If it does not, the car may open but fail to start.
Common symptoms
The engine may crank and stop, the security light may stay on, or the remote may work while the key fails to start the car.
Useful details
Tell us the vehicle make, model and year, and whether you have any working key.
