Programming Additional SecuriLock Keys

Programming Additional SecuriLock Keys

Introduced to the Explorer in 1998, the SecuriLock Passive Anti-theft System (PATS) features specially coded keys that are programmed to start your Explorer. If you attempt to start it with a key that isn't programmed with the correct code, the engine is disabled to prevent theft. Also with this system, it is not possible for a thief to "hot wire" your Explorer. The instructions* below may be used to program additional SecuriLock Keys for your Explorer (you can have up to 8). Please note that you need two correctly coded keys for this procedure. If you only have one, you will need to go to the dealership where they will reset the computer so the minimum of two keys can be programmed.

Procedure to program spare SecuriLock 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 switch 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 switch.

3. Within five seconds of turning the ignition to OFF, insert the second previously programmed SecuriLock key into the ignition switch and turn the ignition from OFF to RUN (maintain ignition in RUN for at least one second but no more than 5 seconds).

4. Turn the ignition to OFF and remove the second SecuriLock key from the ignition switch.

5. Within 10 seconds of turning the ignition to OFF, insert the unprogrammed SecuriLock key (new key) into the ignition switch and turn the ignition from OFF to RUN (maintain ignition switch in RUN for at least one second). This step will program your new SecuriLock key.

6. If it is desired to program additional SecuriLock key(s), repeat this procedure from step 1.

If the programming procedure was successful, the new SecuriLock key(s) will start the vehicle’s engine. The theft indicator (located on the instrument cluster) will light for three seconds and then go out.

If the programming procedure was not successful, the new SecuriLock key(s) will not operate the vehicle’s engine. The theft indicator will flash on and off. Wait at least one minute and then repeat the procedure from step 1. If failure repeats, bring your vehicle to your dealership to have the spare SecuriLock key(s) programmed.
