1) Turn ignition to OFF.
2) Locate the Data Link Connector, its a black 16 pin connecter that is under the driver's side dash, right where your right knee would be.
3) Ground pin 1 of the Data Link Connector by taking a wire or paper clip and running it from pin 1 to pin 4. Pin 4 is ground so you can just short pin 1 to 4 and it will be grounded. Grounding pin 1 tells the system you are ready to reprogram it.
4) Close all of your doors.
5) Turn the key to ACC then back off. The door locks will lock/unlock. This is the signal that the system is ready for reprogramming.
6) Push a button on your remote, doesn't matter which button.
7) If you have 2 remotes, then press a button on the 2nd remote within 1 minute of pressing a button on the 1st remotes. Both must be programmed at the same time. If you only have 1 remote then press a button 2 more times to signal that you only have one.
8) The doors will lock/unlock to signal the codes were received.
9) Remove the jumper wire from the data connector.
Good luck... I think I got everything
I have a 2005 w/ the same problem. Did this method work for anyone? I went to do it and realized that pin1 is blank. I looked it up on the service manual and it is supposed to be blank, so it's not just my truck. Therefore, I don't see how connecting a ground (pin4) to nothing is going to do anything. I was going to try other pins, but I'm not real excited about grounding out various pins. Any advice would be appreciated.
thanks
I have the owners manual.
the re programing is only IF you have an original working key bob.
I would not need to buy one if I had one.
I tried the other ways mentioned in this tread, but no luck there.
do you have a link for the shop manual?
it is a 2002 2500 ram with the ctd.
