Remote door locks won't program tried many times door lock button on door also don't work

Step 1 – Check the Battery Sometimes your programming problem happens as the result of a low battery. Be sure to put a fresh battery in the remote before you reprogram, or you’ll end up with the same problem. Step 2 – Locate Data Link Connector Under the driver’s side dash, there is a 16 pin connector. This is located near where the right knee is when driving. Use a wire to ground pin 1 by connecting the wire to pin 4. Pin 4 is a ground pin, so when pin 1 is connected, the system is ready to reprogram. Step 2 – Insert Key Put the key in the ignition and turn to “ACC” then back to off. Doors lock and unlock signaling readiness to program. Step 3 – Push a Button Choose any button on the remote and push it. If you have a second fob, push a button on that fob as well, within one minute. If you only have one fob, push the button several times. Doors lock and unlock to signal they are done. Step 4 – Remove Wire Remove ground wire, and the reprogramming is finished.
