Replacement keys
If your keys are lost or stolen and you don't have an extra coded key,
you will need to have your vehicle towed to an authorized dealer. The
key codes need to be erased from your vehicle and new coded keys will
need to be programmed.
Replacing coded keys can be very costly. Store an extra programmed key
away from the vehicle in a safe place to help prevent any
inconveniences. Please visit an authorized dealer to purchase additional
spare or replacement keys.
Programming spare keys
A maximum of eight keys can be coded to your vehicle. Only
SecuriLock 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
3
programmed coded key into the
ignition and turn the ignition from 1
2
(off) to the 3 (on) position
(maintain ignition in 3 (on) for at
4
least one second).
2. Turn ignition to 1 (off) and
remove the first coded key from
1
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 1 (off) to the 3 (on)
position (maintain ignition in 3 (on) for at least one second but no more
than ten seconds).
4. Turn the ignition to 1 (off) and remove the second coded key from
the ignition.
5. Within twenty seconds of removing the second coded key, insert the
new unprogrammed key (new key) into the ignition and turn the ignition
from 1 (off) to the 3 (on) position (maintain ignition in 3 (on) for at
least one second). This step will program your new key.
