Car Alarms: Factory alarm not working, yukon xl, simple answer

Question
My 2000 yukon xl had a after market alarm, so they bypassed the factory alarm.  When I hit the lock on the fob the interior lights come on. How can I undo the bypass?

Answer
Take this to a technician. You will need to determine
the make of the device, find the manual for it, and have a
tech, re configure it the way you want it.

I caan not provide a simple answer for this without all
the details, visual inspection, and see the wiring done
first hand.

Best suggestion is to have a pro do this.

Good luck.
