Attention: Existing remotes may be deleted from the system’s memory once a new remote has been programmed. So, make sure to reprogram them if you wish to use them as well.

1. Insert the keys in the ignition then twist it OFF to RUN 8 times within 10 seconds, ending in OFF position (this is to put the system in programming mode for your new remote). You will know your system has entered the programming mode once the door locks cycled (lock then unlock).

(Note: The RUN position is as far as you can turn the key  without cranking the engine. If the door locks do not cycle indicating programming mode has been entered, try the procedure without doing step 1 and having the driver door closed. If you still can’t get into programming mode after trying this numerous times both ways then you either do not have the factory keyless entry system or it is not functioning properly. In many vehicles you should end in the RUN position and not the OFF position. If you have anti-theft deterrent then before doing
this step you should open the driver door and cycle the power door locks twice. This means you press LOCK, UNLOCK, LOCK, UNLOCK. Step ones says to turn from OFF to RUN up to eight times. If the locks cycle before eight times then move onto step 2 immediately. Do not continue cycling the ignition switch.)
2. Within 15 seconds, press ANY button on a keyless entry remote transmitter. The doors will lock and then  unlock to confirm that each keyless entry remote transmitter has been activated.
(Note: When the first keyless entry remote transmitter is programmed, all existing keyless entry remote transmitters are erased.)
3. Repeat step 2 immediately for each transmitter that will operate the vehicle including your old ones (if any.)
4. If the door locks did not cycle, wait 10 seconds and press any button again.
5. To exit the system from programming mode just turn the key in the ignition to OFF position or wait up to 30 seconds after step 2.
