Hey thanks for the reply, to answer your question it is a 1999 Yukon Denali and no no critter marks or anything like that....

Here’s a post from another site. Might be worth checking
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.
