Permanent hazards on

[Bmwe5320023.0]

I'll jump right into it.

My remote key wasn't working for a while, I was just using the key itself to lock and unlock the vehicle by physically turning the key.

Went to unlock it today, and I think the cylinder barrel broke for good. The key just spins inside. I ordered the repair kit right away and called a tow.

The tow guy opened the driver's side door, and the alarm went off. Now it goes off all the time, no matter what. When I'm driving it goes off continuously.
Central lock/unlock button doesn't work, turn signals obviously don't work, it's just flashing all hazard lights.
I had to pull the fuse for the siren in the meantime.
If I turn off the vehicle, it will stop flashing.
If I sit in a running vehicle for a while, it will stop flashing.
I don't know what to do in the meantime lol. I'm going to try and scan with ISTA and see if I clear the errors.
I feel like the barrel cylinder might be stuck in the "lock" position, so maybe the car thinks it's trying to lock itself all the time
