lexophile Posted July 30, 2009 Share Posted July 30, 2009 This here is a tough one! I have an LS430 just approaching 100k. My remote keys will no longer lock/unlock the doors! I have changed the batteries on all my fobs. I have tried reprogramming according to instructions. The central locking works if I hit the switch inside the car, so all is connected there. The car locks if I touch the door handle when outside, it will not unlock it that way though. When attempting to program the fob or the key, I follow all the instructions but when I get to the part where I have to hold the lock and unlock buttons on the key, they cycle the locks constantly rather than the once its supposed to do. (so the remote key is talking to the transponder) if I use the key to gain access the door opens but the alarm goes off until I start the engine! None of the three key I have actually work now. Does anyone, anywhere have any ideas??? PLEASE!! Quote Link to comment Share on other sites More sharing options...
