disconnecting the battery may reset it

SOURCE: 1995 Buick Lesabre: security blinks and car will not start

If the starter is turning the engine, try re-setting the security system (leave key on till light stops blinking.) If the starter does not turn, you may have some success in re-setting system, if not you need to check battery voltage and voltages in starter system till you find the problem...can be something as simple as a bad connection at the battery. If you need help with further testing, just ask.

sounds like you have a short in the horn wiring or a bad ground wire these grounds are mostly located under the engine compartment near the back wall whitch is called the fire wall or beside the fenders

I had the same problem. The alarm system on my 1997 Le Sabre self-actuates. Luckily, it went off once when I popped the trunk. I went to Auto Zone and bought a generic trunk replacement lock. I noticed the original lock had a funky push-pull type of switch used to activate the alarm. This switch was likely hair-line on/off and when the temperature changed, it activated.

I went ahead and replaced the lock without the switch, but you can try simply unplugging the switch through the hole in the metal behind the lock to see if that might stop the alarm from arming itself (or cut the wire).

Good luck, it's a "hairy" problem.
