This is usually a good situation to bring to alarm shop and have them take it out and see if you can just keep the remote start or it might need a new brain on the alarm system

Some lady helped me get manual instantly from www.reliable-store.com thanks. best site for this

your car have a soon roof ? check if safe close

you must use the remotes to lock/unlock the car,otherwise it thinks your trying to steal it....

With alarm activated your ignition is disabled.Find the combination to disable it.With GM's you hold opposing buttons on the fob till it beeps twice. The dealer should help for no charge.

when you disarm the alarm make sure you hear a beep beep sound twice before you try to start the car.

this could be a couple of minor things which we can check first, open and close each door to see if they all operate the courtesy lights, open the trunk and push the trunl light button to ensure it is switching off. there may also be a button under the hood. lastly check the glove box button is turning off the glove/jockeybox light when it is closed. if any of these fail, that is the button that needs to be removed and inspected. Good luck

I have been having this same issue for the past 6 months. So far no one can give me an answer that solves the problem. I have done several things unsuccessfully 1) changed the battery (still happens) 2) flipped the valet toggle switch under the steering column (still happens) 3) I lock the doors using the automatic lock button on the driver and/or passenger door (the alarm will not self-activate and go off, but this still doesn't solve the root problem with the alarm)

The battery is low which is causing the alarm to activate, replace the battery. I'm going to guess that it gets pretty hot where you are between the times you listed. BMW cars have been known to be affected by heat.
