Keyenabler theft-deterrent systemThe Keyenabler theft-deterrent system is an ignition disabling/enabling system for engine-powered vehicles of any make or model. A wireless relay snaps where the starter relay would normally be, or wires in line between the battery and solenoid. The engine will not start until the user enables the wireless relay with the keypad or keychain fob. Systems start at $149. Models with real-time event logging are also available.
