To program the transmitters, perform the following procedure while seated in the vehicle driver's seat:

Close all the vehicle doors.
Remove the ignition key from the ignition lock cylinder.
Press and hold unlock on the door lock switch.
Important: To successfully enter the keyless entry programming/diagnostic mode, steps 4 through 6 must be completed within 25 seconds of pressing the door unlock switch.

While holding the door lock switch in the unlock position, insert and remove the ignition key twice. Do not rotate the ignition lock cylinder.

Factory keyless?

The keyless entry is designed to work with the doors closed (closed - not locked). If the door ajar sensor thinks the door is open the keyless entry is disabled. When you manually lock the door it might tighten the door just enough to activate the keyless entry. I would try slamming all the doors closed and then see if the keyless entry works. If it still wont work have the wiring checked on the front door lock.

replace the remote key battery.

Most probably the lock actuator is frozen in down position. it could be your lock cylinder, but the actuator is the most common problem. You have to remove the inner trim panel to access it.
