Had same problem on my 2002 Buick Lesabre. Lights would not turn off. I noted there was no "door ajar" message and all doors would generate the door ajar message properly. So I turned my research to the lighting switch on the inside panel. I pulled the switch out. Was easy in my 02 buick lesabre. Then I pulled the switch apart and carefully cleaned the interior light slider switch as it was dirty and had carbon buildup. I put it back together and reintstalled and yeah the lights worked properly. Alternatively you can buy a new switch from store or parts yard

You see the cars these days are riged to be always hot but require a ground to connect. The carbon buildup on slider switch was grounding the lights to always on. Free 20 minute fix.

The complexity of the problem depends upon whether your Buick has lights with or without illuminated entry. In the former, a remote accessory control module is used in addition to an interior lamps relay position F circuit which could have a sticking relay. The "simpler" circuit has no remote accessory control module.

I have GMC 1999 suburban wont start and it has the security light on

If it is a Pass III system like my 1999 Buick LeSabre. It means the key is weak. When my car was four years old this happened with all my keys at once. I found in the manual it stated if chip fell out system would reset immediately instead of 2 or 3 minutes. I bought a key from Sears identically cut to my GM but blank no chip to reset the system. When I tried it the car started and I bought four more keys and have used them since. ( 8 yrs) They cost $1.29 each, and have never left me waiting in a cold car again.

Security light stays on

First place to check would be a fuse.  See if there is one labled security or alarm.  If there is try changing that.
