KeyenablerThe Keyenabler "smart" ignition system uses a wireless relay in place of the engine's standard starter relay. Each operator receives his or her own code. Once the code is accepted, the operator can use the ignition key (or button that replaces the key) to start the vehicle. Because the starter relay has to be enabled before the vehicle will start, equipment cannot be hotwired.
