Question about GMC Envoy

1 Answer

I have a 2004 GMC Envoy with 6 cyl engine. Both remote keyless entry went dead at same time and now I can't unlock the back hatch door. I had to release it manually but the sensor keeps locking it back. Tried: removing the Neg from battery for 30 minutes to reset modules. Didn't work. Considering: reprogramming the keyless entry remotes, changing the door lock actuator solenoid. Any other solutions?

Take it an have it check at a qualified repair shop for DTC'S - diagnostic trouble codes . Could have problem with the liftgate/endgate module. Don't try guessing to find a repair .
The keyless entry system has the following main components:
• The transmitters
• The endgate module (EGM) (XUV only)
• The liftgate module (LGM) (Except XUV)
When you press a button on a transmitter, the transmitter sends a signal to the liftgate module. The module interprets the signal and activates the requested function via a class 2 message over the serial data line.
Do you know what class 2 serial data communication network is ?

You need a scan tool to program the remotes .
Program All Key Fobs
To complete this programming operation, all keyless entry transmitters associated with the vehicle must be available for programming. Once placed into program mode, all previously programmed transmitters will be erased from memory upon the receipt of the programming signal from the first transmitter.
Close the lift gate.
Ignition ON, access the scan tool Liftgate Module Setup menu and select Program All Key Fobs.
Follow the the scan tool on screen instructions in order to program the transmitters. Select "Start" on the scan tool to enter the program mode.
As each transmitter is successfully programmed, the scan tool will show how many transmitters have been placed into memory.
When all transmitters are programmed, exit the program mode by selecting "Stop" on the scan tool. The vehicle will not respond to the transmitters until the program mode is exited.
Operate the transmitter functions in order to verify correct system operation.

SOURCE: keyless entry won't work

I have a 1999 BMW E46 I have had a problem with the keyless entry myself. I brought the car to BMW Dealer and they told me that my Lock had an issue and that they need to repair some wiring wich would cost me $1,023.98 to find out that it was a fuse that burned out. I have replaced the 5 amp fuse with another one but it burned the fuse again so I put a 10 amp fuse and i have not had a problems since. In my car is fuse # 54 if Im not mistaken. But waht you can do is open the fuse box which is located in your glove compartment look for a diagram that shows you which fuse is where it will give you a fuse name a number where the fuse is located and how many amps fuse it is.

I went through programing as far as lock recycling but wont go any further


Remote Transmitter Programming NOTE: All keyless entry remote transmitters must be programmed at the same time.
NOTE: Programming (or reprogramming) the keyless entry remote transmitters into the central security module can be accomplished using a diagnostic tool or by carrying out the following steps.
  1. Turn the ignition switch from OFF to RUN eight times within 10 seconds, ending in RUN. If the module has successfully entered program mode, it will lock and then unlock all doors.
  1. Within 20 seconds, press any button on a keyless entry remote transmitter, and the doors will lock and then unlock to confirm that each keyless entry remote transmitter has been programmed. Repeat this step for each transmitter.
  1. If the door locks do not respond for any keyless entry remote transmitter, wait several seconds and press the button again. If the door locks still fail to respond, refer to Inspection and Verification.
  1. Turn the ignition switch to the OFF position, or wait up to 20 seconds after Step 2, to exit program mode. If a keyless entry remote transmitter has been programmed (or reprogrammed), the doors will lock and unlock one last time to confirm.

2003 gmc envoy keyless entry is locked and will not unlock with the key or the remote. it does lock - horn and lights illuminate. is it the remote or the car? I can't even unlock to pop the hood.


if your key is not working to unlock door==try turning key over and then try to unlock door. I have had keys made for replacements and they sometimes don't work quite right one way but work just fine the other way.

to unlock hood with out being able to get inside; you need to reach up from under car and pull/yank on cable to unlock hood.

I have a 96 ford conversion van with a 600 plus addon keyless system and need to program new keyless remots , need to know how to get system in program mode.


Hi.

To program ( or reprogram ) a keyless entry remote transmitter into the remote keyless entry module, perform the following steps:

1. Turn the key to ON or ACC and short the two terminals of the program connector, a two-pin connector located below the driver's side of the instrument panel at the base of the steering column. All doors should lock and then unlock.
2. Press any button on each keyless entry remote transmitter in turn. All doors should lock and then unlock. If the door locks do not respond, press the button again (up to three times maximum with the same keyless entry remote transmitter). If the door locks still fail to respond, go to Pinpoint Test A.
3. Repeat Step 2 to program additional keyless entry remote transmitters into the remote keyless entry module (up to four keyless entry remote transmitters maximum).
4. Turn key off.
5. Remove the short from the program connector. All doors should lock and then unlock.
6. Verify that the keyless entry remote transmitters have been successfully programmed by pressing the LOCK or UNLOCK button on each one, and observing that the system responds by locking and/or unlocking the doors.


I hope this helps you.

Thanks!

Sounds like you need a new keyless entry box, but forst try resetting the computer, by taking the positive battery cable off for 10 mins.
