Has anyone installed the OEM alarm?

I went to install it today, got all the parts and pieces in properly and the damn thing wouldn't start. For some reason whatever I had installed drained the battery quite rapidly. I had the radio on but the car off while I was installing it. That was about 20 minutes. Not nearly enough to kill the battery.

Any suggestions? This should be an easy DIY.

Fortunately BMW roadside assistance showed up in about 30 minutes

Dunno what would have done that. Just jump it and see if everything works.

yeah it was jumped. I ripped everything out first though. I may just have the dealer install it. If it breaks, it's their problem.

the dealer must activate it. it cost me $60

I have install the OEM alarm in my car and it was a piece of cake. But you will need to goto the dealer to activate it in order for it to work. Its about $60 to program your keys and if you have anything else you want to program like turning on or off your day time running lights. I would have them do it at same time.

About draining your battery....:dunno: but I never work on my car with the radio running. I always disconnect the battery so you can't short anything while your working. I like to be safe cus you never know if you bump things by accident.

installing OEM alarm should be an easy DIY:thumbup:
And for the alarm to work, you have to have the dealer activate it.

You should DIY yourself and have the dealer activate it...much cheaper

It was VERY easy actually. I completely installed it, and went to turn the car on - nothing. It just sputtered. The dealer said it'd only be 47.50 to program the key and whatnot. I'm going to try again tomorrow. Worse comes to worst, I'll just jump the battery again.

BTW - what do you use to disconnect the battery? Physically I mean. And do you disconnect the connection in the front or back?

I disconnect right at the battery in the back and just used an adjustable wrench or socket wrench. good luck

Thanks - I'll try it again tomorrow. Fortunately BMW roadside assistance is FREEEEEE

Ok - it works. NEXT time I will disconnect the battery FIRST. I just have to go get it programmed.
