Thank you for the response to my problem. I checked all and the opening and closing of doors with the dome light. Light stayed on for all doors, went out evenly at about 30 seconds. Is there a fuse for the security/alarm circuit? Not in the fuse panel inside driver side on firewall or outside under hook by battery.

I have a 1997 ES300, when doors are locked often the horn alarm goes off—but not immediately. Took to a Lexus dealer where they replaced a rear door actuator for around $400. Did not fix problem. I cannot find a fuse location for the alarm—if there is one. Neighbors do not like the middle of the night horn recital!
