The remote key fob doesn't work( all the buttons) I just took it apart and went and got a new battery.
Put it back together and still none of the buttons work.
Is there a process or a step I'm missing ? Something to code the fob to the car?
Thx all

Might have damaged the board possibly, or might have put the battery in the wrong way (ie positive up and negative down or vise versa). I'd check out the battery and make sure it was put in right.

Well the battery I took out was a energizer # 2016 so I bought the identical kind .
Is their a way to test the circuit board ?
Maybe that went bad?
