ok, This may be a stupid question, but I searched and found nothing. I took my truck back for an oil change last week. While I was there I asked him about Key FOB #1 and #2. The salesman told me they remember the driver and move the mirrors/seats/etc when the ignition is turned on to the memorized position for that driver. This was not happening and I could not find anything in the owners manual about it. I know there is the button on the door I can use, but it did not work by just using the key fob. Since my mom's Cadillac does this I figured I would ask. The service writer said it does, but he wasn't sure how. He said the salesman knew how to do it. Of course he couldn't locate one that knew how and I got tired of waiting.

Do the key fobs really remember the driver and adjust it all or do I just have to use the buttons on the door? If so how do you program them?

They got rid of that feature in 2004...

The 2005's and up dont have the feature to recall seat position regarding to which remote is used.

I bought a spare a while back off Ebay. Here are the instructions from it:

1. Close all vehicle doors.

2. Insert ignition key into the ignition lock cylinder.

3. Press and hold the door unlock switch on the door panel.

4. While holding the door lock switch in the unlock position, cycle the ignition ON, OFF, ON, OFF. (within 5 seconds).

5. Release the door unlock switch. The doors will lock and unlock to confirm the program mode.

6. Press and hold the LOCK button and the UNLOCK button simultaneously on one transmitter. After a delay of approx. 15 seconds, the doors will lock and unlock to confirm the programming of that transmitter.

7. Repeat the previous step to program up to four transmitters.

8. Turn the ignition switch to the RUN position in order to exit the keyless entry transmitter mode.

9. Operate the transmitter functions in order to verify correct system operation.

Speaking of remotes...My wife drives a Yukon, and I have the truck, so we have TWO remotes on each key ring, and it's kind of a PITA. Is there any way "secret code" to program one remote to operate with both vehicles? Or do I have to buy a new remote with more functions?

Thanks-

How long do you hold the Lock/Unlock for? 15 seconds?
Mine does nothing after this point, but I think my BCM is bad.

I've seen them take as much as 30 seconds to program. Other times it may take a few tries before they program.

The problem would be if they were parked close to each other, the remote would lock or unlock both at the same time. When you enter the programming, the existing remote id's are erased, then the module picks up the id from the remote being programmed. So, you should be able to program to one vehicle, then walk over and program the same remote to the next vehicle. I think it would be worth a try to see if it works.

Huh?!? So it is *actaully* programming the vehicle to the remote, and not the other way around? In that case it should work, but when they're both parked in the driveway theu would both unlock. Still, might be better than stuffing a key ring with 2 remotes in my pocket. Plus, I wouldn't be hitting the wrong one all the time.

Thanks for the tip.

It has been the same on the Silverado since 1999, but some trucks are pretty touchy and may need the Tech II to program.

Yup. That's what I was trying to say, though I couldn't seem to find the right words to make it easy to understand.:)

The progrmming method presented above does not work on the Medium Duty Trucks (my 2005 C4500 Chevrolet).

Does anyone know how to program the Key FOBs on the MDT?????

  1. <LI type=1>Connect a jumper wire between the keyless entry program enable signal circuit of the data link connector and a good ground. <LI type=1>Press and hold the LOCK button and the UNLOCK button simultaneously on one transmitter. After a delay of approximately 10 seconds, the doors will lock and unlock to confirm the programming of that transmitter.
    Important

    Program additional transmitters within 1 minute of the previously programmed transmitter.

    <LI type=1>Press and hold any button on the next transmitter to be programmed within 1 minute of the previously programmed transmitter. After a delay of approximately 2 seconds, the doors will lock and unlock to confirm the programming of that transmitter. <LI type=1>Repeat the previous step to program up to 4 transmitters. <LI type=1>Remove the jumper wire from the data link connector in order to exit the keyless entry transmitter mode.
  2. Operate the transmitter functions in order to verify correct system operation.
I think this will help you out, though I'm not sure it is for the correct truck.
