Replacing coded keys can be very costly and you may want to store an
extra programmed key away from the vehicle in a safe place to prevent
an unforeseen inconvenience.
The correct coded key must be used for your vehicle. The use of the
wrong type of coded key may lead to a “no start” condition.
If an unprogrammed key is used in the ignition it will cause a “no
start” condition.
Programming spare keys
A maximum of eight keys can be coded to your vehicle. Only
SecuriLock娂 keys can be used. To program a coded key yourself, you
will need two previously programmed coded keys (keys that already
operate your vehicle’s engine) and the new unprogrammed key(s) readily
accessible for timely implementation of each step in the procedure.
If two previously programmed coded keys are not available, you must
bring your vehicle to your authorized dealer to have the spare coded
key(s) programmed.
Please read and understand the entire procedure before you begin.
1. Insert the first previously
programmed coded key into the
ignition and turn the ignition from
the 1 (OFF/LOCK) to the 3 (ON)
position [maintain ignition in 3 (ON)
for at least three seconds, but no
more than ten seconds].
2. Turn ignition from 3 (ON) back to
the 1 (OFF/LOCK) position in order
to remove the first coded key from
the ignition.
3. Within ten seconds of removing the first coded key, insert the second
previously programmed coded key into the ignition and turn the ignition
from the 1 (OFF/LOCK) to the 3 (ON) position [maintain ignition in 3
(ON) for at least three seconds but no more than ten seconds].
4. Turn the ignition from the 3 (ON) back to 1 (OFF/LOCK) position in
order to remove the second coded key from the ignition.
5. Within 10 seconds of removing the second coded key, insert the new
unprogrammed key (new key/valet key) into the ignition and turn the
ignition from the 1 (OFF/LOCK) to the 3 (ON) position [maintain
ignition in 3 (ON) for at least three seconds, but no more than ten
seconds]. This step will program your new key to a coded key.
