Hi Guys,

This is my first post here! - so I"m new to the forum, but no so to the nice RR.

Today in the morning my 04 RR HSE let me down and won"t open anymore the doors for me nor is reacting to the FOB.
Hoever the manual try to open it thru the drivers door keylock let the car wake-up, but no interior light nor I was able to open the doors manually.
I can pull on the handle as much I like but nothing happens. I had also a locksmith come out and we tried to open up the doors from inside and pushing the unlock button - no luck at all.

Battery is a half year old and I drove it yesterday - no problems at all.

Is there a other way to go in?

Thanks for any sugestions
Chris

Sounds like a power issue, new battery or not. You should start by trying to get power to the car. This is not easy. Various approaches. Some go through the starter cables, others open the hood through magic (lots of work), some through the trailer hitch if optioned, and finally some go through one of the rear side markers. For this approach you need to remove the rear side marker from the outside and send power through the wiring. If you do some digging you will find more information and more specifics. You are not the first or the last with this issue. What I mentioned above is what I have learned reading on the issue, preparing myself for your situation (which fortunately has not happened to me). I recommend the last solution as those that have done this have had success and it is very easy to do and causes no damage.

The door handle key will not work without power - so that is a clue this could be your issue. Once you get in you need to sort out what drained your battery - don't think it a random occurrence. Once the system is powered the key should work.

if its too cold to work,
drag the truck onto a flatbed and take it to the shop, they should be able to add 12V to the starter lug or get into the truck via the hatch

Thanks everyone for the help
I made a lot of magic and after several hours and a lot of bad words I finally was able to pop the hood
Now the alarm is going, me under the hood handling with cables :lol: and everyone passing by, watching me!
Battery tester connected and battery OK 12,3V - so, what next?
I disconnected the battery, after the obligatory 5 min pause and went home for lunch.
Now back with help and while I connected the battery my helper pulled on the handle and ... success the door opened, but the problem is still there. The RR is running and drives, but is not reacting to the FOB nor to the lock button. I guess that the BCM may be not so happy anymore or do he have a buddy somewhere for the central locking function?

I would spend the $25 to get a code reader for your car. This one works for the 2003 - 2005 with the BMW electronics. Scan tool on Amazon.

It says it only works on XP, but I'm running it on my 64 bit Windows 10 laptop. Had to download the drivers from the web and install them, and it works great. I also had to jumper a couple of pins on the device. Some ship jumpered, mine didn't. I'd be willing to submit a step by step process if anyone is interested.
