Try closing all the doors. Using the key in the drivers side door turn the key to lock all doors (i think it's to the right) then turn the key twice the other direction; unlocking all the doors and the alarm should stop. This just happened to me tonight.

Factory alarms rarely false alert, maybe someone did tamper with the car and ran off before you saw him. The one thing that will often trip alarms is a bad battery in the car, have it tested. Your car may have an add-on alarm in which case anything goofy can happen. It's odd that you had to hit the panic button to shut the alarm off, but if it functions normally otherwise it's unlikely to need a new battery. Is it at all possible that you hit the panic button and that caused the alarm to sound? If it was in your purse or pocket maybe it got pressed in which case it might be normal for you to have to hit panic again to turn it off.
Hi, if the car stay for long time the computer box lost memory. Now is not reading the key. You need to program your key again by BMW manufacturer. Also on bmw the alarm is connected to computer box too.
I had the same problem when my battery went flat and tried to use jumper cables connected to another vehicles battery. I called Volvo and they said I need to disconnect the battery terminal to reset the computer. After re-conecting it the remote control worked again and I was able to jump start the car. Maybe your car's computer went into a similar state.
Put your key in the drivers side door lock and hold it to the left. The alarm will sound for a couple seconds and then turn off. Open the door, hop in, and start your car and off you go................we have waited 4 weeks to find out how to solve this problem........hope this is useful to someone.
It is probably the remote. If you need to, to de-activate the alarm get in the car with all doors shut and turn the key to the on position and leave it for a couple of minutes, then the car will start. I haven't ever had to replace the etacs module for that complaint.
