Hello I've got a bmw 520i se model J reg. The alarm used to work on the key fub and would close all the windows and sunroof and open and close the doors.

There a small key you can you on the alarm siren to switch it on and off saying a bmw system. That works fine you switch it on the red light flashing inside the car fine. You can open and close the doors but the red light stays on flashing. If you go in the car the alarm will go on and lights flash and siren going.

Anyway bought new battery for the alarm fob cause it had run out. The light flashes on the fob showing its working. The fob black with 2 grey bottons. The key just standard with a light on it.

How do I re program the fob again?

Also how do I get the alarm to work with the normal door lock key?

Do a search with the words 'program alarm fob' and read some of the posts. I remember one of those thread covers programming :thumbsup
Been having alook there diffrent ones. Also Im not an expert on these cars. But the details must be the same as others.

Yes Pete, most BMW alarms are the same fitted over the different range of models. I'm guessing you have a Scorpion or something similar.
Hello do I need to take pictures of the fob and the siren so people know wat kind it is?

That isn't a standard BMW alarm, with that fob it's a aftermarket job, I've seen the small key before but not the fob I'm afraid :frown
Hello were the key goes in the small one in the siren. It has a bmw badge with a code on it?
