Video: Non stop beeping sound. Car has no power!
I walk up to my car this afternoon and this non stop beeping noise is happening. The car has no power and I can't turn it off! I disconnected both batteries and the sound persists.
What could cause this? Is this the anti theft alarm. Is it a faulty LOW TONE ALARM SIREN HORN?

that or the alarm module. It's tucked under the driver's side fender, and it has it's own battery so if it tweaked out while it was dying, it will stay like that until the battery exhausts itself or you pull it out and throw it in the river.

Dead battery!
Turns out my gf left the lights on and the battery died. As it was dieing it set off the anti theft alarm. I measured the battery at 5 volts. Jumped it and noticed the lights were set on instead of auto. Also on a weird note, I still have a red battery alarm except my consumer items like AC, heater, seats control/cooling heat/ and lighters are all working again.

I used a Battery Tender model to bring my Aux battery back to like, took 5 or 6 days, it was at 5.5v before I hooked it up. Battery lasted another 2 years.
