When the vehicle has successfully entered programming mode, all door locks will cycle automatically. (ATTENTION: RUN position is as far as you can turn the key without starting the engine. If the door locks did not cycle it means you're not in programming mode, try the procedure without doing step 1 and having the driver door closed. 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. So you press LOCK, UNLOCK, LOCK, UNLOCK. Step one says to turn from OFF to RUN up to eight times. If the locks cycle before eight times then move onto step 2 immediately.
2. Within 15 seconds, press ANY button on the remote. Then doors will lock and unlock to confirm that each
keyless entry remote has been paired. (Note: When the first remote is programmed, all existing remote transmitters are erased.)
3.Go back to step 2 immediately for each remote that will operate the vehicle including the old ones.
4. If the door locks didn't do anything when you pressed the button on your remote, wait about 10 seconds and
press any button again.
5. Turn the key in the ignition to OFF position or wait up to 30 seconds after step 2 to turn program mode off.
If a keyless entry remote transmitter has been activated, the vehicle may lock and unlock all doors one last time to confirm.
