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 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).
4. Turn the ignition to OFF and remove the second SecuriLock key
from the ignition.
5. Within 10 seconds of turning the ignition to OFF, insert the
unprogrammed SecuriLock key (new key) into the ignition and turn
the ignition from OFF to RUN (maintain ignition in RUN for at least one
second). This step will program your new SecuriLock key.
6. 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.
