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.
Does it turn over and start?
Does it do anything?
Comment me back with your findings

Check battery voltage. if above 13.7 volts move to rear lock actuator and measure battery voltage at actuator if above 13.6
replace actuator if below specs. check grounds and alternator out put as follows, alternator output 13.7 to 14.25 volts. key off battery volts should be 12.90 + - 3/10 of a volt and about the same voltage at the actuator. let me know. kindest regards Bill

Here is a secret, I go to the Salvage Yard and buy them for $10.00 and reprogram them for the match the car's. When you go to the Salvage Yard, if there organized will have sets of fob keys in a box. Go though it and look for the same FCC numbers on your working Fob key and here is the instructions for you to do the relearn for your 2003 Yukon XL.
1. Close all vehicle doors.
2. Insert the key into the ignition.
3. Hold down the power UNLOCK button on the driver’s door panel-continue to hold
down until instructed to release in step 9.
4. Perform steps 5 through 8 in fairly rapid succession.
5. Turn the ignition switch to the ON position (as far as you can go without starting the
6. Turn the ignition switch to the OFF position.
7. Turn the ignition switch to the ON position.
8. Turn the ignition switch to the OFF position.
9. Release the power unlock button on the door panel. The vehicle will lock and unlock
the doors automatically.
10. Hold down the LOCK and UNLOCK buttons on the transmitter simultaneously until
the door locks and unlocks.
This step may take up to 30 seconds.
11. Repeat step 10 NOW for each additional transmitter (including any existing
12. Turn the ignition switch to the ON position in order to exit the transmitter programming
Good luck and thank you for using Fixya, just call around the different Salvage yards if not you can try E-bay.

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

locks have so many key positions but on a popular vehicle this can happen where they have the same key indentations ,but yopu friend couldnt start your car as it has a chipped key ,but years ago in the car rental we had two fiat puntos parked in the same car park in torrevieja and they got taken by the wrong persons so we had to drive around and find the houses and get the cars back and swop them over .but this was before chipped keys ,also had it with two ford fiestas in benidorm as well
