I recently changed the battery on my key fob for my ssanyong rexton. I then did the following for the key fob to make it work. 1. Enter vehicle and close all doors.

2. Put seatbelt on (or clip it into the buckle) to shut the warning buzzer off.

3. Put key in ignition, turn to run position but don't start it.

4. Press and hold both buttons on key fob until red light on fob stays on. Then let go of both buttons. Then pressed the alarm button then the panic button, somthing like that. To be fair the button sequence after the red light came on is a bit vague. The alarm was blaring so i was happy when it just stopped.

try to take the ******** and try without it if it doesn't work try again after putting it back in
