Controls and features The SecuriLockT passive anti theft system is not compatible with aftermarket remote start systems. Use of these systems may result in vehicle starting problems and a loss of security protection. Large metallic objects or devices such as the Mobil SpeedpassT on the same key ring as your SecuriLockT key may cause vehicle starting problems. These objects and devices cannot damage the SecuriLockT key, but can cause a momentary problem if they are too close to the key when starting the engine. If a problem occurs, turn ignition off and restart the engine with all other objects on the key ring held away from the SecuriLockT ignition key. Spare SecuriLockT keys can be purchased from your dealership and programmed to your SecuriLockT passive anti theft system. Refer to Programming spare SecuriLockT keys for more information. If one or both of your SecuriLockT keys are lost or stolen and you want to ensure the lost or stolen key will not operate your vehicle, bring your vehicle and all available SecuriLockT keys to your dealership for reinitialization. 72
