Have you been able to repair? What was the problem? My Yukon XL started doing this 2 days ago.

My Yukon XL started having the same problem. Any answers?

My 2000 Yukon SLT started having this problem in March, 2010. Today I solved it. My alarm is factory/dealer installed, so yours may be different.

On the underside of the dash to the left of the steering column is a small black box (about the size of your thumb) with a red LED on the front. On the back side of the box is a push button. Turn on the ignition key (don't start the engine)and press and hold this button for about 8 seconds, until the LED stays red continuously. This resets the alarm.

My car now responds properly to all variations of locking/unlocking and no longer randomly starts beeping.

Same symptom. I have the lift style tail gate and the problem was within the push mechanism that opens the rear glass window. Once this problem was solved the alarm functioned normally again.
