Locks and Security
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 dealership to have the spare coded key(s)
programmed.
Please read and understand the entire procedure before you begin.
1. Insert the first previously
3
programmed coded key into the
ignition and turn the ignition from 2
2
(OFF/LOCK) to 3 (RUN) (maintain
ignition in 3 (RUN) for at least
4
three seconds, but no more than ten
seconds).
2. Turn ignition from 3 (RUN) back
1
to 2 (OFF/LOCK) 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 2 (OFF/LOCK) to 3 (RUN) (maintain ignition in 3 (RUN) for at
least three seconds but no more than ten seconds).
4. Turn the ignition from 3 (RUN) back to 2 (OFF/LOCK) 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 2 (OFF/LOCK) to 3 (RUN) (maintain ignition in 3 (RUN)
for at least three seconds, but no more than ten seconds). This step will
program your new key to a coded key.
6. To program additional new unprogrammed key(s), repeat this
procedure from step 1.
If successful, the new coded key(s) will start the vehicle's engine and the
theft indicator will illuminate for three seconds and then go out.
If not successful, the new coded key(s) will not start the vehicle's engine
and the theft indicator will flash on and off and you may repeat steps 1
through 5. If failure repeats, bring your vehicle to your dealership to
have the new spare key(s) programmed.
