Just looked at the diagrams, use a link to disarm aux from the alarm via a relay (5 wire) to either black, blue or white going into the driver's door test which unlocks, of those three and that's the one to unlock when you turn off the alarm (with R/S) operating when you approach the vehicle. If taken from the central module, it will unlock all the doors, if taken from driver door loom, kick panel it will give you priority driver door unlock.

This seems like it will work. This will only be a solution to unlocking the doors when remote started using the remote starter's remote, correct? Therefore a remote starter with a remote without lock/unlock will not work here? I wonder if there is a solution where the factory key fob can be used.

No idea, never had this problem with a BMW before except an early battered X5 where the door module was faulty.
Actually you could run with this method to give you priority unlock on any BMW 98-05.

I was able to use multiple suggestions to come up with a solution. Here is what I ended up doing. I used a combination of multiple ideas. This was the one that I thought was the easiest. I used the remote start to unlock and disarm the vehicle before starting using the arm and disarm in the door. This helped provide synchronization. Once the vehicle was remote started, I used a relay on an extra ignition output on the remote starter to trigger the button on the console. This only operated while the engine was running. I then programmed lock after start. Which keeps the vehicle protected. This also set up the correct sync so when the customer walks up to the vehicle it will be ready to unlock. I had to tie lock and unlock together on the console switch as it is a flip flop. This is why the sync is important. If the customer doesn't hit either lock or unlock twice in a row the sync is always right on. Once I shut the vehicle down we went back to using arm and disarm at the driver door. Thus keeping all features. Possible solution for anyone with the same issue. It worked out great for our shop!

i have a few questions:
if only adding a single button remote starter, will ignition and transponder disarm fact alarm before remote start like tech files claim?
once remote started, if customer shuts off starter while approaching vehicle via remote, will factory remote unlock car without any issue?
im looking for a "less expensive" solution for these vehicles....
