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

How do I make my AC work when I turn on my YUKON DENALI 2007 with a remote?


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.

I have a 2002 yukon denali. Somehow my viper alarm needs reset. I cannot start the truck. When I replaced the car battery it was fine. Now when I press the buttons on my remote it does not do anything....


Your 2002 Denali is equipped with a security system from the manufacturer. The installation of aftermarket security systems such as the one you are describing is just trouble waiting for a place to happen.

General Motors has published several Technical Service bulletins regarding such aftermarket equipment and warns of the problems that can occur including No-Start conditions, trouble with the keyless entry system, engine misfire problems, transmission shifting problems and severe damage to high-dollar parts like catalytic converters.

My professional recommendation is to remove all of the aftermarket equipment from the vehicle and resore the vehicle wiring harnesses to a condition that would be acceptable to the people that built the vehicle.

Yes i have a 2007 gmc yukon denali. when i bought it they didnt give me the keyless entry pad with remote start, then when they did give me one it wasnt the one for my vehicle, they told me all i had to do...


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

2007 gmc yukon denali wont unlock w/ keyfob


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

How come on a 2002 GMC Denali if you lock your key inside


i would say the theft module saw the door trying to be open without the door lock or fob first, once the door lock button was pushed it shut down, it new doors were trying to be unlocked in a theft manner, once shut down it needs time to reset or needs to see ignition cycle with key and read chip in key, smart system isnt it, good luck.

Keyless remote Problem for Yukon Denali 2005


Have your dealership test the remotes for you, they will also use a "Tech-2" to re-program it and should not charge you to do so. "I know mine does not" The "puddle" lamps come on when you un-lock the doors with the remote."If they are enabled in the options on your dash information center or "DIC". "See owners manual for info on that". As far as the DRL's make sure your bulbs are good because they are known to blow out. But the remote should not have anything to do with those.Hope that helps a little?
