2000 bmw 5 series remote start

I already have the tech sheets for this car and all in all it dose not seem to be to bad except the fack of having to go into the drivers door. My question is, I will be installing a remote start and keyless entry in this vehilce. The key has the chip in it and the tech sheet calls out a DEI 556UW. This is where I need some insight. First of all the BMW key has the factory remote built into the key head so the head of the key is somewhat big. Will this key fit into the box? I do not have one on hand as they are on order. Also the BMW keys have a battery in them. The battery charges when the key is in the ignition. Dose the battery need to remain charged for the 556 to be able to pick up the signal from the key or is the battery strictly for the remote? Also if anyone has done one of these before klet me know how hard it was as well as any helpfull tips you may have

Thanks in advance for all of your help.

Lot's of tabe..... This I have done several times...

Center it with a tiny bit, test it.....then tape the cr*p out of it!

I will be installing a R/S and keyless system in a 2000 5 series. The one question, prob. a dumb one, I see that the factory alarm is operated by the door locks and the doorlock wires are inside the drivers door. Is there a way to momentary bypass the factory alarm during the remote start operation insted of having to unlock the vehilce before remote starting it?

also how much of a pain is it to get the drivers door panel off on this car. I seem to hear many of rumors about this car so any help would be great.

Thanks in advance

1.) No

2.) it's a pain

Check to see if your unit can be programmed to lock after start....like an astrostart.

Well after a long 7 hours I can say that BMW is now on the bottom of my list. I will most likely never want to do another one.

One problem that I ended up with was the battery was dead when I was done. I as pretty sure that this was because the drivers door was open for the 6-7 hours I was installing. One another note here is where the problem is, if it is coincidental or not I am unsure. The seatbelt light along with the transmission light are on. Acording to the guy I installed it for he said that the seatbelt light was never on. The light does go out when the belt is plugged in just like any other vehicle so I do not know what is going on here. As for the tranny light, everthing shifts fine on the car so there is nothing wrong with the tranny. I used both ignition wires as well as the 3 red 12V wires and the black starter wire. Tagged the door/alarm wires inside the drivers door, connected the 556U ( I did not use the ring, I tapped into the factory 2 wire ring per the DEI instructions)

Any help would be great,

Thank you.

Quick update!!

All the lights are off and the cart is running with no issues. It seems it was just a strange fluke, perhaps when we jump started the car.

My insight to everone that wants to do this car, PASS on it. It is do-able but getting through the door and pulling it apart i have to rate it a 9 out of 10.
