Note: Disarm the alarm first and make sure valet switch is accessible before you program the remote to the system.
1) Twist the key in the ignition to ON position.
2) Within 7 seconds press the valet switch/button 5 times. You’ll hear a chirp as a confirmation from putting the system to programming mode.
3) Press the LOCK button on your remote (for Freedom 500, C-5, and K9 Mundial2, press 2nd or 3rd channel. For MARS-22, press Lock & Unlock at the same time). And you’ll hear short siren chirp.
4) Re-do step 3 adding another remote to the system (up to 4 remotes).
Note: Your system will exit the programming mode after 15 seconds of being idle.
