hello members I have an issue with the key fob for my 2000 s2000, the key fob is programed and when i go to hit the unlock button the car does not unlock or lock, the lights on the dash light up along with the park lights but the car does not unlock or lock with the key fob, the trunk and panic button works fine but nothing with lock and unlock, could it be something with the aftermarket cd player that is in the car or am I just thinking outside the box ?

if anyone has a fix to this issue or is having the same issue please let me know !

Thanks
Thomas

 

I don't think the locks run through the radio, look at a wiring diagram. I would think its the multiplex cm. but that's just an educated guess
