My 01 4runners keyless entry stopped working after I was rear-ended. Ive looked at multiple threads explaining how to reprogram it. The only problem is i dont think it needs reprogrammed because that didnt help at all. Im pretty sure the system either came unconnected or a fuse has been blown. If anyone can help me figure this out it would be greatly appreciated.

 

The radio receiver part of the keyless entry is part of the Back-Door ECU, and there is an antenna wire inside the liftgate. I'd open up the liftgate and inspect for physical damage and go from there.

Does your panic button work?

 

That makes sense because I was rearended by a big ass jeep with a steel bumper. They must not have fixed the key fob system. None of the buttons on any of my fobs work.
