Program a remote to the DCX

The DCX has to be flashed and programmed to the vehicle, and unlocked or disarmed, before it will learn a remote. It holds up to 4 remotes and only learns from the LOCK button. On a 1-button remote, tap once: a double tap is unlock and a hold is remote start.

  • 1. Cycle the ignitionWithin 7 seconds, turn the key OFF to ON five times quickly. The parking lights flash once.
  • 2. Press LOCKWithin 5 seconds, press LOCK once on the remote. The parking lights flash once: that remote is stored.
  • 3. More remotesPress LOCK on each other remote the same way, up to 4 in total.
  • 4. FinishWait for the parking lights to flash twice, then turn the ignition OFF.

Push-to-start: press the start button to ON (don't start), back to OFF within 5 seconds, then to ON again within 5 seconds. Press the brake 3 times within 5 seconds: the parking lights flash once. Tap LOCK on each remote (one flash each). It leaves programming on its own after 5 seconds with no remote.

More answers for the FT-DCX

Automatic transmission: cut the black loop

The DCX is in manual transmission mode until the black wire loop on the control module is cut. On an automatic vehicle, cut the loop before you program the module.

If the parking lights flash 3 times and then 7 times when you try to remote start, the loop hasn't been cut. If the module was already programmed, cut the loop, do a system reset (see the master guide), then program it to the vehicle and learn tach again.

Valet mode

Valet mode turns off the remote starter. Lock and unlock still work. Use it when the vehicle is being serviced. If you try to remote start in valet mode, the parking lights flash 3 times and then 10 times.

  • With the keyWithin 7 seconds, turn the key OFF to ON twice quickly, then press and release the brake 3 times. The parking lights flash once, then twice. Turn the ignition OFF. Do the same again to leave valet mode.
  • 4-button remoteTo leave valet mode, press LOCK and TRUNK together for half a second. The parking lights flash twice.
  • 1-button remoteTo leave valet mode, turn the key ON and tap the button 5 times within 10 seconds, waiting for the remote's light to stop flashing between taps. The parking lights flash twice.

Valet mode can also be switched on or off in your DroneMobile account settings.

Remote start didn't work? Read the flashes

When a remote start fails, the parking lights flash 3 times, pause, then flash a code:

  • 1Tach not learned, or the engine is already running.
  • 2Key is in the ON position.
  • 3A door is open.
  • 4The trunk is open.
  • 5The brake pedal is pressed.
  • 6The hood is open.
  • 7The black loop isn't cut (automatic vehicles).
  • 8The vehicle failed to start.
  • 9Vehicle movement detected.
  • 10The system is in valet mode.
  • 11Vehicle communication (CAN) failure.
  • 12Not synchronised: start the vehicle with the key for 15 seconds, then try again.
  • 13Immobilizer bypass problem.
  • 14Idle mode or takeover isn't available on this vehicle.
  • 15Overheat protection.

This only works when the parking lights are connected to the system.
