Key Fob Question

[elav]

I have a key fob that came with my car but has never worked for me (as it looks like it went through the clothes washer by the previous owner). I found someone that is going to either repair the board or move the main chip over to a spare fob board.

Once he does the repair, we will want to test it. Seeing as this car hasn’t received a signal from a fob in at least a year, is there anything special I need to do or should it simply work (assuming the fob is repaired)? Thanks ahead of time!
