Car Alarms: car alar,, 2007 chevy tahoe, chevy tahoe

Question
I have a 2007 chevy tahoe and today I went to a glass place to get my windshield replaced. After leaving I did a few errands and kept hearing a horn of an alarm go off about every 5 minutes and it was honking for about 5-7 times and then would shut off on it's own. I brought it back to the glass place for them to say they did not cut anything so I would have to bring it to the dealer, called them and they can't see me for 4 days. Cannot lock the car even if I locked the doors manually cannot lock the hatch in back because there is no key to that it is locked by the remote. Any ideas what is happening nobody seems to want to help me.
Thank you in advance

Answer
It is obvious they did not connect the senor wiring back into place with the ne glass. Best thing is to run into GM and have the service dept. tend to it.
Then send the bill to the glass company for
they're insurance to pay.

That sort of thing is just iresponsible.
Show them they are acountable.

Good luck.
