Keyless remote Problem for Yukon Denali 2005

Probably a bad fuse.

It sounds dumb but make sure you hit the lock button first I had the same problem and that works for me

If the control is set for ac when you turn the engine off, it should come back on when you start it by remote. Is the radio and other accessories working when you use the remote ? Could be the remote system is not powering the accessory circuit for some reason.

Is this an issue with all 2008 HHR remotes??? Highly doubtful , probably the vehicles keyless entry system . Taking the vehicle to a qualified repair shop an having the keyless entry system checked for DTC'S - diagnostic trouble code's . Do you know what a DTC is ?
The keyless entry system is a vehicle entry device. The keyless entry system is used in conjunction with the body control module (BCM) to remotely activate certain vehicle features. Keyless entry will lock/unlock the doors, or release the rear compartment lid when a corresponding button on the keyless entry transmitter is pressed. This is accomplished by the transmitter sending a radio frequency to the remote control door lock receiver (RCDLR). The RCDLR interprets the signal and activates the requested function via a serial data message to the BCM. A low transmitter or vehicle battery or radio frequency (RF) interference from aftermarket devices, such as 2-way radios, power inverters, computers, etc., may cause a system malfunction. High RF traffic areas may also cause interference that could lead to a malfunction. Keyless entry allows you to operate the following components:
• Door locks
• Liftgate lock
• Remote rear doors (Panel only)
• Vehicle locator/panic alarm
• Illuminated entry lamps
• Remote vehicle start
The keyless entry system has the following components:
• Keyless entry transmitters
• Keyless entry antenna
• 2 Way Advanced Remote Start RCDLR
• BCM

Guessing will not fix this .

Did you Check your Remote's Battery if enough Power, Change Battery .
Or the remote module has no power, Needs reprogrammed again.

Close all the vehicle doors.
Insert the ignition key into the ignition lock cylinder.
Press and hold the DOOR unlock switch.
While holding the DOOR lock switch in the unlock position, cycle the ignition ON, OFF, ON, OFF.
Release the DOOR unlock switch. The doors will lock and unlock to confirm the program mode.
Press and hold the LOCK button and the UNLOCK button simultaneously on one keyless remote. After a delay of approximately 15 seconds , the doors will lock and unlock to confirm the programming of that transmitter.
Repeat the previous step to program up to four transmitters.
Turn the ignition switch to the RUN (one more click forward) position in order to exit the keyless entry transmitter mode.
Operate the transmitter functions in order to verify correct system operation

my remote start ont work but door locks work 2007 buick

Check the buttons.. I have an 06 Grand Prix with the Remote starter on the top and it seems that the conductor on the buttons worn out.. Take the keyfob apart, pull the rubber buttons off the chip, lick your finger and touch the place where the unlock (right side of the fob) would be. That should unlock your doors. I just did it with mine. I would just buy another fob on ebay and change the buttons out.. Hope this works

change battery in your remote.

Hi Russell,

Absolutely no power? No dome light? No head lights? Nothing?
When you step on the brake pedal, no brake lights?

If true, start at the source and pop the hood.

This is going to be a bit of back and forth dialogue. I'll ask some questions and you get me the answers. That way we can get to the root of the problem. To save time, I'll ask multiple questions at a time. Here goes.

• Check the battery. Is it still there? (Valid question with no evidence of power)
• Are the terminal clamps tight?
• Are the terminals clean and free of corrosion?
• Are all the belts in place and tight? (pay special attention to alternator)
• If you have a voltmeter. test the voltage at the battery terminals. It should be +12.5VDC.
  

Try getting a jump, when the cables are attached does anything light up?
Does it turn over and start?
Does it do anything?

Comment me back with your findings
Mike
