1999-2003 Protege OEM Keyless Entry Code Change How-to
The following is a how-to on changing the security codes on the remote and keyless entry module in case you are either paranoid or having problems with your keyless entry.
1. Make sure there are no keys in the ignition and that all doors are closed
2. Open driver's side door
3. Insert key into ignition switch and cycle the key between the ON and LOCK positions 3 times
4. Remove key from ignition switch
5. Push the driver's side door sensor switch 3 times
6. Verify that the doors lock and then unlock.
If nothing happens, wait 40 seconds and start from step 3 again
7. Press any button on any transmitter twice
8. Verify that the doors lock and then unlock
If nothing happens, see note A
9. If you have only 1 remote, press any button on that remote twice.
If you have 2 or 3 remotes, press any button on any of the other remotes twice.
10. Verify that the doors lock and then unlock
If nothing happens, see note A
11. If you have 1 or 2 remotes, press any button on either remote twice.
If you have 3 remotes, press any button on the 3rd remote twice.
12. Verify that the doors lock and then unlock
If nothing happens, see note A
13. The codes should now be reprogrammed
Note A:
1. Hold down the driver's side door sensor switch
2. Verify that the doors lock and unlock twice
3. Start from step 3 again
If you start working on 1 remote, finish working with that 1 remote until you're done reprogramming it!!!
