When the LED on the 2WG5R-SH remote flashes red at you it means that you are in ‘2nd car mode’. Because of this the remote is attempting to communicate with a second vehicle that is not existent. In order to exit this mode:
- Press and hold the unlock and trunk (buttons II and III) together for 2.5 seconds.
After doing this the LED should flash green and the remote will become functional again. If this does not seem to fix your issue, attempt to replace the battery on the remote and try again.
Note: You must be within range of the vehicle, the vehicle's engine should be shut off, and the alarm should be disarmed.
