Controls and features Programming spare SecuriLockி keys Spare SecuriLock௢ keys can be purchased from your dealership and programmed to your SecuriLock௢ passive anti-theft system (up to a total of 8 keys). Your dealership can program your new SecuriLock௢ key(s) to your vehicle or you can do it yourself using the following simple procedure. To program a new SecuriLock௢ key yourself, you will need two previously programmed SecuriLock௢ keys (keys that already operate your vehicle's engine). If two previously programmed SecuriLock௢ keys are not available (one or both of your original keys were lost or stolen), you must bring your vehicle to your dealership to have the spare SecuriLock௢ key(s) programmed. Procedure to program spare SecuriLockி keys to your vehicle New SecuriLock௢ keys must have the correct mechanical key cut for your vehicle. Conventional (non-SecuriLock௢) keys cannot be programmed to your vehicle. You will need to have two previously programmed SecuriLock௢ keys and the new unprogrammed SecuriLock௢ key readily accessible for the procedure. Please read and understand the entire procedure before you begin. 1. Insert the first previously programmed SecuriLock௢ key into the ignition and turn the ignition from OFF to RUN (maintain ignition in RUN for at least one second). 2. Turn ignition to OFF and remove the first SecuriLock௢ key from the ignition. 3. Within five seconds of turning the ignition to OFF, insert the second previously programmed SecuriLock௢ key into the ignition and turn the ignition from OFF to RUN (maintain ignition in RUN for at least one second but no more than 5 seconds). 62
