Make sure the system is disarmed before you program the remote and you must know where your valet switch is located.
1) Turn the the key in the ignition to ON position
2) Within 7 seconds, press the valet switch/button 5 times. And you should hear a long siren chirp.
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). The alarm should respond with a short siren chirp.
4) Go back to step 3 to program another remote (a maximum of 4).
Please Note: Your system will automatically exit from programming mode after 15 second period of no activity.
