2.2 General Programming Procedure
To program the remote, you will typically need to access your system's valet switch (also known as the programming or override button). The exact location of this switch varies by vehicle and installation. Consult your vehicle's alarm system manual for its precise location.
- Prepare the Vehicle: Ensure the vehicle's ignition is OFF and all doors are closed.
- Enter Programming Mode:
- Insert the key into the ignition.
- Turn the ignition to the ON position (do not start the engine).
- Within 5 seconds, press and release the valet switch a specific number of times (e.g., 3, 5, or 7 times, depending on the system). The system will usually respond with a chirp or light flash to confirm entry into programming mode.
- Program the Remote:
- While the system is in programming mode, press and hold the LOCK button on the new CAT4M remote for approximately 1-2 seconds.
- Release the button. The system should chirp or flash its lights to confirm the remote has been programmed.
- Exit Programming Mode:
- Turn the ignition OFF.
- The system will typically chirp a few times to indicate it has exited programming mode.
- Test the Remote: After exiting programming mode, test all buttons on the new remote to ensure proper functionality.
If you encounter difficulties, repeat the procedure or consult a professional installer.

- Carefully snap the remote casing back together.
- Test the remote's functionality.
