You must have a seperate remote and key for this procedure to work.

If your vehicle uses the smart key/smart entry then it must be programmed by a locksmith.

1.   Close and lock all doors with the driver’s side power lock/unlock switch.
 
2.   Insert key into ignition and remove it from the ignition key cylinder at least six times 
     within 10 seconds. Your Hazard Lamps will flash if you have performed this step 
     successfully. NOTE: Withdraw key completely from ignition cylinder each time. If this 
     procedure is performed too fast, system will not enter programming mode. 

3.   Insert key into the ignition cylinder and turn to the ACC position.

4.   Within 5 seconds, push ANY button on the remote transmitter. Your Hazard Lamps should
     flash. NOTE: Do not press the button more than one time in the above step. If the button
     is pressed more than one time, the programming procedure will not be successful.

5.   If there are any remaining transmitters (including the old ones), unlock then lock all doors
     using the driver’s side power lock/unlock switch and within 5 seconds, push ANY button 
     on the next remote. Your Hazard Lamps should flash. Repeat this step for each 
     transmitter (including any existing transmitters). 

6.  Turn the key to the OFF position, remove keys from the ignition, unlock doors using the 
    driver’s side power lock/unlock switch and open the driver side door.
