Controls and features SECURILOCKT PASSIVE ANTI-THEFT SYSTEM Your vehicle is equipped with a coded key anti theft system. Only the correct key will be able to start your vehicle. If your keys are lost or stolen, you must take your vehicle to your dealership for key reprogramming. The SecuriLockT passive anti theft system provides an advanced level of vehicle theft protection. Your vehicle's engine can only be started with the two special SecuriLockT electronically coded keys provided with your vehicle. Each time you start your vehicle, the SecuriLockT key is read by the SecuriLockT passive anti theft system. If the SecuriLockT key identification code matches the code stored in the SecuriLockT anti theft system, the vehicle's engine is allowed to start. If the SecuriLockT key identification code does not match the code stored in the system or if a SecuriLockT key is not detected (vehicle theft situation), the vehicle's engine will not operate. 71
