I'm not savvy with car electronics/alarms, but I have an Alpine SEC-8028 and the alarm was functioning no problem. i let my car sit for a couple weeks and so i took the battery was weak took it to charge it. when I hooked it back up it was chirping non-stop so I disconnected it, reconnected it and i figured all is good. I may have pushed a few buttons on my remote by accident when trying to get the alarm to stop chirping

i have a feeling it's in some sort of valet mode, as now it doesn't chirp when arm/disarm, just lock/unlock with lights flashing once. on top of that it now auto locks the doors when i start the car, and auto unlocks the doors when i turn it off. any idea how to get it to stop auto lock/unlock and get the chirp back when i lock the doors? i read the manual and it didn't help me much
TIA
