Step-by-Step Programming Instructions:

**Note**: This procedure is for programming the remote portion of the key/remote.

1. Close all doors. Then, open the driver’s door and press the UNLOCK button on the driver’s door panel while the door is open. Insert the key into the ignition.

2. Turn the ignition from OFF to RUN 8 times within 10 seconds, with the 8th time ending in RUN. The door locks will cycle to confirm programming mode.

3. Within 20 seconds, press any button on the first keyless remote. The door locks will cycle to confirm programming.

4. Within 20 seconds, press any button on the second keyless remote. The door locks will cycle again to confirm programming.

5. Turn the ignition to OFF. Locks will cycle again to indicate the end of programming mode.

To program the key portion of the key, you must already have two working keys. If you only have one working key, then you will need to have a locksmith program a second key with special equipment, or you can buy a programmer.

To program the key portion:

1. Insert an existing working key into the ignition cylinder.

2. Turn the ignition cylinder to ON (RUN) and then back to OFF.

3. Remove the existing working key and, within five seconds, insert a second working key and turn it to ON (RUN), then back to OFF.

4. Remove the second working key and insert the new key before ten seconds have elapsed. Turn it to ON (RUN). Leave it on for one second and then turn back to OFF.

5. The security light will light up for three seconds to indicate that the new key has been successfully programmed.
