I have the same issue, not the keyless entry fobs but the module. It has been too hot to get inside the trunk to pull it out. I was hoping there is just a loose wire and I won't have to go buy a module. I'll keep you posted.

    I wasn't to clear in my answer...sorry. My keyless entry fobs were not the issue so the next place I suggest you check is the module that runs the keyless entry(unlocks/locks the doors, trunk, fuel door & also controls the security system. It is located in the trunk left side all the way to the back wall of the trunk. The module has a foil piece that can wear away it's like a transmitter antenna. You will have to put a tester on it to see if you are getting any current.

1998 Buick Park Ave. courtesy likes don't work along with trunk release button, A/C ducting vents only work on passenger side (A/C works otherwise). Dash lights only come after dark.


This is not a BCM problem , if it were there would be DTC'S - diagnostic trouble codes stored in the BCM ! Need a factory or professional grade scan tool . Ther HVAC - heating ,ventilation an A/C venting problem is more then likely a mode door actuator problem , an it's not controlled by the BCM .
courtesy likes don't work, I'am assuming you mean courtesy lights ? The trunk release problem could just be the lock actuator or the release relay in the rear fuse/ relay box . Regardless of the problem , checking for DTC'S with a capable scan tool an view inputs to the BCM is the proper why to diagnose these type problems ! Not guessing an assuming it's the BCM ! There is a lot of wiring an messaging between modules on serial data network ! There are other qualified independent repair shops !
Rear Compartment Lid Release Description
When the valet lockout in the rear compartment lid release switch is in the UNLOCK position, battery positive voltage (B+) is applied in the following ways:
• From the TRUNK REL fuse
• Through the contacts of the rear compartment lid release relay
• Through CKT 56 (BLK/WHT) to the rear compartment lid release actuator
The rear compartment lid release actuator is grounded at all times through CKT 650 (BLK) to ground G400.
Pressing the rear compartment lid release switch provides a ground input signal to the body control module (SBM) through CKT 1576 (BLK), the switch contacts and CKT 450 (BLK). The SBM provides a message on the Class 2 serial data line to the remote function actuator (RFA) module. The RFA module in turn grounds the rear compartment lid release relay control at terminal A1. This terminal grounds CKT 1344 (LT BLU) which energizes the rear compartment lid release relay coil. The relay contacts close in order to perform the following functions:
• Actuate the rear compartment lid release actuator
• Release the rear compartment lid.
The rear compartment lid may be released using the keyless entry transmitter regardless of the valet lockout position. Pressing the rear compartment lid release button on the transmitter provides a signal to the remote function actuator (RFA) module. The RFA module grounds the rear compartment lid release relay control at terminal A1. This ground applied to CKT 1344 (LT BLU) actuates the rear compartment lid release relay.
Replacing a BCM without knowing what your doing could make thing's worst . These modules need to be programmed , Dealer only !
Your light problem probably is do to a none functional panel dimming module ! Lamp control module !
This vehicle has only one BCM !

Body Control Module (SBM)
Under the right side of the IP, near the rear of the IP compartment
Lamp Control Module (LCM)
Under the left side of the IP, to the right of the steering column

Rear Junction Block
In the center right rear of the passenger compartment, under the rear seat cushion

Trunk locks not opening


This is very complex if your not familiar with how Class 2 serial data communications work . When you press that trunk lid release button it sends a low voltage signal to the BCM - body control module. Here is how the factory service info. says how it works .
When the vehicle is in park and the trunk release switch is pressed it grounds the rear compartment lid release switch input in the Body Control Module (BCM). The BCM then sends a Class 2 message to the Remote Function Actuator (RFA). The RFA supplies an internal ground for the coil side of the rear compartment lid release relay activating the relay. The rear compartment lid release actuator receives battery voltage through the 15 A trunk release fuse when the relay closes. Ground is supplied by G400.
Your best bet is to take your vehicle to a dealer or some other qualified repair shop that has a factory scan tool or a professional grade type .
You could check the TRK/REL relay in the rear fuse/ relay box .Because you can't test the class 2 data to the rear integrated module. Fuse Block Rear
Under the left side of the rear passenger compartment seat

Can I reprogram my keyless remote from my 1995 eldorado to my 1996 cadillac eldorado

I recieved message ( RFA1 Battary low ) what does that mean


RFA means radio frequency actuation. This usually indicates one of your key fob batteries are getting weak. They work off RFA, by remotely operating your door locks thru radio signals. Its best to change the batteries in both remotes at the same time. They shouldn't, but not always need reprogramming. After replacing the battery, simply press the lock and unlock buttons together to re-synchronize the key fobs.

How do I program a Cadillac 2004 Deville remote key fob?


came across this, maybe this will help out...this is for analog gauges....

With the ignition in the "RUN" position (engine does not necessarily need to be running, but it will work either way).
Press OFF and WARMER (or the OFF and PASSENGER WARMER buttons) on climate control panel simultaneously. Instrument Panel Cluster (IPC) will light all telltales, then go blank. System is now in DIAGNOSTIC MODE. After diagnostic mode cycles through and stops, press FAN DOWN button until "RFA?" is displayed, then press FAN UP. If "RFA DATA?" is displayed, press FAN DOWN. If "RFA OVERRIDE?" is displayed press FAN UP button.

If "RFA S00 NO OVERRIDE" is displayed, press FAN DOWN. If "RFA S01 PROGRAM FOB #1" is displayed, press FAN UP button.

IPC will show "0" on right side of Drivers Information Center (DIC) display. Press WARMER button on the climate control unit until "99" is displayed.

Press and hold TRUNK button on the transmitter. While holding TRUNK button, press LOCK button and hold both buttons for a total of 3 seconds. Locks will cycle when programming is complete. If transmitter is not programmed within 30 seconds after entering "99" on the display, system will default and you must begin at step #2 again.
To program second transmitter, press FAN DOWN button until "RF S02 PROGRAM FOB #2" is displayed, then press FAN UP. Repeat step #4.

To exit system, press AUTO, MODE UP, MODE DOWN, or RESET button.
