For owners of a Chrysler PT Cruiser, the vehicle may come equipped with a Sentry Key Immobilizer System. The Sentry key helps to mitigate the risk of theft by shutting down the engine if someone tries to start the vehicle with the wrong key. Authorised Sentry keys have an embedded transponder chip. This chip stores a programmed code that must match with the car's computer when starting the engine.
