Key Fob Reprogramming

[Texas Jim]

Just bought a 2001 DeVille....can I add a fob to this car myself or does a dealer have to do it?

.....

Hello? anybody on here now days?

I don't know about your 2001... but on the 2006 it is fairly easy to add one..

Dealer NOT required...

Hopefully someone with a 2001 service manual will chime in.

Same problem here, I've tried 4 times, and the FOB only works while in the console. BRAND new batteries. Any other ideas?

I did consult an Owner's Manual and found 2 specific passages in relations to matching the key fOB and key. I lofe is goint well.

rom 2-11

Matching Transmitter(s) to Your Vehicle

Each remote keyless entry transmitter is coded to

prevent another transmitter from unlocking your vehicle.

If a transmitter is lost or stolen, a replacement can be

purchased through your dealer. Remember to bring any

remaining transmitters with you when you go to your

dealer. When the dealer matches the replacement

transmitter to your vehicle, any remaining transmitters

must also be matched. Once your dealer has coded the

new transmitter, the lost transmitter will not unlock your

vehicle. Each vehicle can have only four transmitters

matched to it.

Since all vehicles come with only two transmitters, you

must check with your dealer for information on how to

obtain additional transmitters.

All transmitters must be present when replacement or

additional transmitters are being programmed.

From Page 2-21

To program the new key:

_ Insert the current driver’s key (black in color) in the

ignition and start the engine. If the engine will not

start see your dealer for service.

_ After the engine has started, turn the key to OFF, and

remove the key.

_ Insert the key to be programmed and turn it to ON

within ten seconds of removing the previous key.

_ The SECURITY light will turn off once the key has

been programmed. It may not be apparent that the

SECURITY light went on due to how quickly the

key is programmed.

_ Repeat the Steps 1 through 4 if additional keys are

to be programmed.

I havr a 1998 cadillac seville.i lost the remote and bought a new one, how do I program it?

[Cadillac Jim]

Hey, I keep that around in a text file:

Resynchronizing the FOB
If you are getting B3108 (Transmitter Synchronization Failure) you may need to resynchronize the fob.

From the 1997 FSM, page 9K-5, the process or resynchronizing the RFA with your fob is:

Press and hold the TRUNK button and within one second, press and hold the LOCK button.
Continue to hold both buttons for approximately seven seconds and then release.
If the transmitter was out of synchronization, it will now function properly.



Programming the FOB
If you are getting B2560 (RKE Message Validation Error) you may need to reprogram the fob.

The FSM, page 9K-4, gives this procedure for programming the fobs. It begins with a warning that you *must* program both or you won't succeed in the programming, but my dealer did exactly that once, when I had a bad fob on warranty. But, I wouldn't try it. They say that if you have only one fob, program both fob 1 and fob 2 to it. If you find the other fob later, you can always reprogram so that the car responds to it.

I'm going to assume that you have a Digital Cluster (the MPH in digits) and not an analog cluster (conventional needle speedometer with tachometer) because you have a Deville, and I don't think that any 1997 model year Deville used an analog cluster. If you do have an analog cluster, say so and I'll give the procedure for programming it.

Here's the process for a digital cluster:

1 Press OFF and WARM on climate control panel simultaneously. The IPC will light all telltales, go blank, and then enter diagnostic mode.
2 Press FAN DOWN to scroll through system until RFA? is displayed, then press FAN UP.
3 Press FAN DOWN until RFA OVERRIDE is displayed, then press FAN UP.
4 NO OVRD RF S00 displayed, then press FAN UP.
5 When PGM FOB1 S01 is displayed, press WARM button, 99 will be displayed in left upper corner of IPC just below odometer. System is now ready to program transmitter.
1 Press and hold the TRUNK button on transmitter.
2 While holding TRUNK button press the LOCK button and hold for one second.
3 Hold both buttons for a total of three seconds. Locks cycle when programming is complete.
4 If transmitter is not programmed within 30 seconds after enering 99 override display, system will default and you must start at step 5 to continue.
6 To program transmitter 2, press FAN UP. Display will show PGM FOB2 S02.
7 Follw steps 5 and 6 to program transmitter.
8 Press RECIRC or RESET to EXIT the system.

Thanks for the info !! So I will need a scan tool in order to do this ???

If you choose to use method #2, yes, you need a scan tool. BUT, if you use method #3, (which takes about a half hour), you do not need a scan tool, but you will have to reprogram all the key fobs for the vehicle.

If you have the time and do not wish to go to the dealer, i would suggest method #3,

Matt

If anyone else is looking for a way to reset/clear already paired key fobs - I was able to do this without the scan tool.

I was able to use Method #3 by not placing any key fob in the pouch and following the instructions. It proceeded to clear all of my key fobs and allow me to reorder them appropriately.

A simple hack - no scan tool needed and better yet: no dealer needed!

Thanks for contributing, plants.

It’s 2019 and this post saved my life. Fortunately I found a loop hole in method 3! When your FOB is already programmed... take the/all programmed FOBs away from the vehicle, lock it, use the hard key to enter the vehicle and then turn the lock 5 times... at this point proceed with method 3. The “key” to this is to turn the lock 5 times before inserting the programmed FOB in the slot. otherwise the vehicle recognizes the FOB and reverts to method 1.
