Mitsubishi Key Fob - recode
Had a dead mitsubishi tear drop style key fob for a cobra alarm. Found some text on the internet that suggested you may be able to recode by shorting some pins on the OBD adapter and ended up nearly setting fire to the car. In the end I found a much safer way that actually worked.
The problem I had was the key fob appeared to be working where the panic button worked and when unlock was pressed the little LED inside did light up but the car didnt lock / unlock.
To fix the issue I had to do the following
Face the car door
Press and hold both buttons on the key fob, the red light should flash and then stay on
Release both buttons and the light should go off
Turn away from the door and press the big button once
Turn back to the door and press the big button again
