Keyless entry problems.

[Jordanbutter]

Ok heres the problem. My keyless entry just up and stopped working one day, the fob isn't dead hence the light still comes on when I press a button. So I read Defiants merged threads on how to reprogram the fob and everything. I put a jump wire in pin 1 and 4 with the key in the off position, shut the door my legs were hanging out of, turned the key to ACC and nothing happened, turned it back to off and back to ACC, again nothing happens. I'm putting the wire in the pin furthest left on the top row of the OBD-II and obviously the one 4th in from that, is that the right pins? And if so then why aren't the locks locking and unlocking like it should? Thanks.

Sounds like you are not getting a good connection between pins 1 and 4. Try stripping more wire so you have a half inch exposed at each end of the jumper. It should bottom out in the socket. (my first wire seemed to fit, but ended up being too big, a smaller gauge wire was the solution)

All doors must be closed (dome lights will be off.)
Attach jumper to pins 1 and 4 (or just plug in an OBDII reader if you have one.)
Turn key to ACC then OFF (doors will lock then unlock.)
Press any key on your fob 3 times (doors will lock then unlock again.)

If turning the key to ACC then OFF isn't working, then either the doors aren't closed or your jumper is wrong.

I tried it with a code reader and pushing the paper clip in as far as I could, with no luck. I even did it with the door closed this time too. Would having a turbo timer mess with any of this, even though it doesn't activate untill the car is on. Thanks.

im having the same problem.

My lights onthe remote however only blink like 1/5 times when i press it. I replaced the batteries. What would be the issue.

Can someone explain what the FOB is and if i have to replace my remote if it IS bad?

The fob is your remote.

Ok I got back in town and tried it again today I shoved the paper clip in there as far as I could and then more and realized it went all the way through. Is that supposed to happen or did I push the wire out and maybe thats why nothing is working.
