Problems with Keyless Entry, please help
So I just received a key fob for my '94 C4 and I went to do the programming and it is not working.
-I am hitting the "Trip Odo" button twice and then pressing and holding the "Fuel Info" until the "Passive Keyless Entry" light comes on the dash, and it does. So far so good.....
-However the next step says to turn the key to the off position and the "Passive Keyless Entry" light should start to flash, but this does not happen. The "Passive Keyless Entry" light just stays on. No flashing.
No matter what position the key is in the "Passive Keyless Entry" light will not flash, and therefore will not program my new key fob I just got.
I have already checked the fuses, and I have made sure the key fob is well out of range and inside the house, and nothing is helping. Could there just be too much interference in my neighborhood? I live right in the middle of Houston. I am out of ideas, any help would be greatly appreciated. I have been manually using the key to unlock since November now.

This old Tech Tip mentions "NOT FLASHING" but says all worked anyway!
Good Luck!

When you turn the ignition key to Accessories or Off, the key cylinder engages a mechanical contact switch.
This sends a ground signal to the PKE module which places the PKE module in program mode.
It also sends a ground signal to the CCM. The Chime module should sound if you open the door. This would confirm the Key in the Ignition Switch is working. (This assumes the chime module is working).
Here is a picture of the switch on a non air bag steering column. It's a copper strip of metal that may just need cleaning with a burnishing file.
To access the switch you need to remove the air bag, pull the steering wheel, move the clock spring for the air bag out of the way and the turn signal switch assembly.

The question is, with the key in the cylinder, does the open door chime sound? If not, you may have a worn cylinder, and the system thinks you have turned the key off and removed it. When you turn the key off try keeping your hand on the key and pushing it in as far as possible. this has worked for some people.
Interference is not the problem, just to be sure I think the fuses are 26, 40 and 42.

Chime works perfectly. I will buy a new battery for the Key Fob and try the instructions where the PKE light was not flashing. Thanks for all the responses I really appreciate it. Gives me something to go from.

Ok so here is exactly what happens:
I get the Passive Keyless Entry light to come on, then when I turn the key to the off position, the door chime starts sounding and the Passive Keyless Entry light will stay on until I bring the Key Fob within 10 feet and then the PKE light will go out immediately and nothing is programmed.

Once I get the PKE light to come on and before turning the key to off, I can get the PKE to go off for an instant randomly by moving the key FOB around. But as soon as I turn the key to the off position the light goes out within a few seconds if the Key Fob is in range.

You have 2 minutes to program up to 3 FOB's.
Did you say with the key in the ignition cylinder key in the Lock position if you open a door the Chime sounds?

When the PKE light comes on solid are you then turning the key to Off or the Lock position? Not sure if it makes a difference but the Service Manual says to turn the key to the Lock position and the PKE light should flash a 1 indicating it's ready for the 1st fob to come in range.

The fact that the key fob does absolutely nothing. No matter how long I hold any button on the thing nothing the key fob does, whether proximity to car or buttons on the key fob, the car does not respond at all to the key fob in any way.

Yes I have tried every different position of the key and the light never flashes just stays illuminated until the key fob is in range, then turns the light out immediately. If the key fob is already in range when I try to get into the program mode then the light just stays on.

I have tried getting into the program mode both with the door shut and open, and it does the same thing, as soon as the key fob is in range it turns the light out. And I still cannot get the light to flash at all.

So is there something in the car like a receiver or wires or anything at all I can check? Is this module or whatever easy to locate and or replace. I feel like I have exhausted all possibilities and I don't feel like my car is possible to program a key fob in its current form. Is there a PKE module?

The module is behind and above the DIC panel area.
If the car is new to you, have you looked for a key fob under the seats or in the
console?
Trying running the PKE diagnostics. The 16 pin diagnostic connector is located under the dash
above the drivers right knee.

Not only could the PKE module be bad since it's not going into Program mode you
also need to verify the new key fob is good.
Some AutoZones have a key fob tester.

'94+ ALDL connector is in this how to that doesn't cover PKE but it's a good read and the image will square you away:
