How do I program my '99 Mitsubishi Diamante to beep or flash the headlights when I lock it and unlock it with the keyless remote?

Answer 1

To program your 1999 Mitsubishi Diamante to beep or flash the headlights when locking or unlocking with the keyless remote, first, turn the ignition key to the "On" position without starting the engine. Then, press and hold the "Lock" and "Unlock" buttons on the remote simultaneously for about 5 seconds until the doors lock and unlock, confirming the programming. If your vehicle supports this feature, you should hear a beep or see the headlights flash when you use the remote. If it doesn’t work, consult the owner’s manual or a dealership for specific programming instructions, as features may vary.
