there are a bunch of schematics for the contents alarm but none seem to have anything to do with the starting. i wonder if whatever is wrong with that is draining the battery and thats whats wrong with the pass key.

"#80-90-08: INFO ON THEFT DETERRENT ALARM SYSTEM INTERMITTENT ACTIVATION - (Jun 26, 199
THIS IS A MONTHLY SERVICE NEWSLETTER ARTICLE. THIS BULLETIN IS NOT INTENDED FOR PUBLICATION.
SUBJECT: INFORMATION ON THEFT DETERRENT ALARM SYSTEM INTERMITTENT ACTIVATION AND/OR SECURITY LIGHT STAYS ON
MODELS: 1992-98 BUICK LESABRE 1991-96 BUICK PARK AVENUE/ULTRA
ON VEHICLES THAT HAVE FORCED ENTRY THEFT DETERRENT SYSTEMS, A COMMON CONDITION HAS THE SECURITY LIGHT STAYING ON FOR ONE MINUTE OR LONGER, OR THE ALARM GOING OFF AFTER THE CAR IS LOCKED. THIS MAY BE CAUSED BY THE TAMPER SWITCHES OR WIRING FROM THEFT DETERRENT/RFA MODULE TO THE SWITCHES.
THE FIRST STEP IN DIAGNOSING THEFT DETERRENT PROBLEMS IS TO CONFIRM THE CAR HAS THE OPTION (UA6) ON THE SPID LABEL IN THE TRUNK. ON LATER MODEL CARS (96 AND UP), WHERE THE THEFT ELECTRONICS RESIDE IN THE RFA MODULE, THIS OPTION CAN BE TURNED ON OR OFF IN THE VEHICLE'* SOFTWARE. IF THE RFA MODULE IS REPLACED, THE OPTION IS ENABLED IN THE REPLACEMENT PART FROM GMSPO AND MUST BE TURNED OFF FOR A CAR NOT EQUIPPED WITH UA6. IF NOT TURNED OFF, WHEN THE CAR DOOR IS OPENED WITH A KEY, THE ALARM WILL SOUND. USE A TECH 1 OR 2 TO TURN OFF THE OPTION.
ON OTHER CARS THAT HAVE THE SYSTEM AND HAVE THE OTHER PROBLEMS, AN EASY WAY TO DIAGNOSE THE CONDITION IS TO BACK OUT THE LIGHT BLUE WIRE AT THE MODULE (CKT 263) AND SEE IF THE CAR NO LONGER HAS THE SECURITY LIGHT MODING PROBLEM OR THE ALARM GOING OFF INTERMITTENTLY WHEN THE CAR IS LOCKED. IF THE SYSTEM OPERATES NORMALLY, CHECK THE TAMPER SWITCHES AND THE WIRING FROM THE MODULE TO THE SWITCHES FOR A SHORT TO GROUND.
IF THE CAR STILL HAS THE PROBLEM, THEN THE THEFT DETERRENT PROBLEM IS IN THE DOOR LATCH (OR DOOR JAM) SWITCH CKT. CHECK THE SWITCHES FOR PROPER OPERATION. CHECKING FROM THE MODULE CONNECTOR, THE SWITCHES SHOULD BE OPEN WHEN THE DOORS ARE CLOSED AND HAVE CONTINUITY TO GROUND WHEN THE DOORS ARE OPEN. IF THERE IS RESISTANCE ON THE CKT WHEN THE DOORS ARE CLOSED, FIND THE SOURCE OF RESISTANCE TO GROUND AND REPAIR. THE RESISTANCE TEST IS ALSO VALID FOR THE TAMPER SWITCHES AND ASSOCIATED CIRCUIT EXCEPT THEY SHOULD SHOW OPEN ALL OF THE TIME"
the manual says the module is behind the pass side fuse/relay panel and you have to slide it out of the way to get to it

Thanks for all the responses guys, unfortunately Ive been working crazy hours at Town Fair, but will be able to try some of these suggestions tomorrow, Sunday since Im off. I did relearn VATs, yes my key has that black chip. Original GM non aftermarket key. It is a Buick Custom if that helps. Still no luck. Looks like I'll have to find one of these tech IIs if I tow the car to them. I will keep you updated tomorrow, thank you once again everyone for taking time out to answer.

Also before I head to work, noticed a new symptom when I get in the key and turn keyu to On and attempt to start. The Anti Lock Brake red light below instrument cluster flashes 3 times then pauses the blinks 3 times so on. Anything useful from that. This also started after disconnecting battery and have had no ABS issue before.
