Are you sure you are talking about the OEM fob that comes with the car? You shouldn't have "hit lock" or press anything. The system works automatically to lock and unlock the doors. The only time you press anything is for the hatch or to enable/disable the automatic system (there is a specific procedure for doing so).

I understand, but yes i am talking about the OEM fob that came with the car, i understand it worked automatically, but you can turn off the auto part and use the button.

You probably need to read the owners manual again on how exactly the factory PKE system works.

The buttons on the FOB will not lock or unlock the drivers door. The "lock" button on the FOB will turn the system on or off as you mentioned.

There are 3 modes of operation:
1. System off
2. System on and only passively unlocks the drivers door.
3. System on and passively unlocks both drivers and passenger door.

In mode 2 above, the button on the FOB will unlock the passenger door.

No you can't. There are no lock buttons on a factory PKE fob. On a coupe there is a button that will unlock the hatch, on verts or coupes there is a "door" button that will unlock the passenger door if you have it programmed that way, but there is no mechanism for locking the car except for walking the fob away from the car.

What? You said you hit lock and it worked. There is no lock. I have no idea what you are saying.

OK, never mind. If you tried to reprogram the system for your fob it should work, doesn't matter if it is already "known" or not. If you cannot reprogram the fob either the fob is not transmitting or your PKE receiver has gone bad. I'm afraid I can't comment on the blink sequence because I honestly cannot undestand what you are trying to say. I would be happy to try and provide some insight if you could provide step by step what happened when you tried the fob programming process.

And RollaMo-LT4, your comments were spot on.

sorry about the confusion, im very bad when it comes to explaining things via text.... so i go to reprogram the remote, i turn the key to ignition, press ODO 3 times and then hold fuel info untill the PKE light goes on steady, turn the key to off position and the PKE blinks as it should, now that blink is on for a second and off for 2 back forth back forth........ for some reason i thought i remembered it being blink on and off equally,, so im wondering if maybe it could be a code or something.... thanks for all you help

I can try and see if I still have a description of the procedure somewhere but anyone with an Owner's Manual should be able to chime in. I seem to recall that the system only lets you program up to 3 fobs (or maybe 4?). If you are having a problem, maybe you had exceeded the limit? Also the obvious--check the battery in the fob.

In my '93 fsm when you program a transmitter it blinks 1 for one transmitter and 2 for two transmitter and 3 times if a third transmitter (fob) was being set or recognized by the receiver. sounds like you have two transmitters being recognized by the receiver. Your not alone I am having other problems with mine to. Lots of good help here.

I think the blinking sounds OK, I would guess the reciever is all right. Don't worry about the 3 fob limit, that isn't a lifetime restriction, it resets when you reprogram. I would suspect a problem with your fob, if you can borrow a fob from someone and try to program it. There have been several threads about repairing fobs lately; try tyaking it apart, cleaning the bearing, check and maybe resolder any suspect connections. Good luck.

So i took this into consideration and it just so happens that i am an electronics engineer so i took it to work sand took it apart and did not see any obvious bad solder connections, followed the circuit with a meter as far as i could and it seemed good. BUT WHAT I DID ANYWAYS WAS RE-SOLDER EVERY SINGLE CONNECTION! WORKS! thanks to everyone who helped out!
