I was told that the antenna amifpiler, that controls the unlocking of the car doors by using the key flob, was not working. I would like to know the part number of this unit. The car is 2000 528i Also, was this part used on any other years or model
You can get the PN for this and almost any other part on your car by checking out realoem.com, and following the prompts for your particular vehicle. It's a great resource I've used time and time again and is basically the same parts catalog your dealer uses.
My guess is that your p/n will be the same as for my non-DSP '99 540. Check it out and let me know what p/n realOEM gives you - I recently bought a used antenna amplifier for my car thinking I had a bad one. As it turns out my key fob is where my problem was, so I never installed the antenna amplifier I bought. I was going to hang on to it, but might be willing to let it go if it's the one you need.
Also - note that there are two "boxes" comprising the antenna amplifier - one in each C-pillar, next to the rear glass. So if RealOEM doesn't give you what you need, you can pry up the rear courtesy lights and lift off the c-pillar interior trim. It's only held on by a few clips and if you're careful you can re-use them. Once those trim pieces are off, you can easily see the amplifier boxes and their part numbers should be clearly labeled right on them.
PS - I believe this part was also used in the 7-series, but don't know which years.

i'll check it out this week. i'm also talking to local dealer to see if this is cover under CPO.
my problem is, both, keys will not unlock doors and i was advised it was the antenna amplifier.
what is SN of your unit?
Before going after the antenna amplifier try checking fuse # 53 in the RR side of the trunk. It is a common problem for this fuse to blow. Usually the root cause is a faulty gas door lid or trunk actuator ( more often the gas lid actuator) Replace the fuse and then initialize the keys using the procedure found at www.bmwtips.com and if the fuse continues to blow try leaving the gas door actuator disconnected for a period of time to see if that keeps the fuse intact. If so then you know the gas door actuator is bad.
