My car is beeping at me after I turn it on, just started 2 days ago. on 1997 Oldsmobile LSS

My car beeps at me after I turn it on. There are no dashboard lights on or check anything lights going. Just had alternator and battery changed. All lights work. I did open the door and hit the security/horn button on my key fob by accident and thats when the beeping after I turned the car on started. Yesterday I hit the button again, and then hit it to turn off the horn/security going on, then started the car and it still beeped at me. Anybody have this issue with their car?

I had the exact same problem w/ my LSS. It's the firewall (between dash & engine) that's allowing the water to get in. The water runs from front to back underneath all flooring layers & pools. My mechanic tore out what was left of the firewall & used some kind of high heat sealant. It still leaks if it rains for an extended period of time.
