Does a 1990 bmw 325i has alarm system?
i got a key and it has a button with a bmw emblem on it I was wondering if its alarm system? It doesnt work now because probably the batteries are dead if its an alarm. I dont want to try and open it because it might break.
Update:wat do i need to do to make it work?

No, they did not come from the factory with an alarm. It was only a dealer add on kit manufactured by Alpine. The roundel emblem button the the key was for the little light in the bottom black head of the key top to help you guide the key in the door lock when it's dark.
i have a 1994 325.
it has a bmw alarm system, but that is nothing to do with the button on the key.
the button on the key is just a small torch.
turn the logo and will pop out. then there is a bit of metal and a spring and a battery.
easy to change, just might be a bit brittle with age
Yep they have them and are better than ANY aftermarket system.
