The alarm manual that comes with the VX only shows how to program the alarm with respect to options. If the remote is no longer recognized by the alarm, it will need to be ’taught’. Depress and hold the green “learn“ button (the only one) located on the bottom of the black alarm box, leftmost box of the brake pedal on the firewall. Then press the lock/unlock button on the remote(s). The Option button can be programmed to do the same thing by pressing it next if you wish.
The remotes/alarm should NOT lose programming when changing batteries or if the car battery is swapped.
