(the comments below are NOT an endorsement that this is the solution to the problem you only gives an example of how easy it is to find the answer to the question quoted above..using the online part case you have other situations like this in the future)

IF...there's something wrong with your (tumbler) ignition...there's no need to replace the key (which would add significantly to the overall cost)...the ignition barrel can be replaced much more cost effectively...and it can be ordered based on your car's VIN/key blade cut etc so that you can keep the keys you already have that also operate your door, trunk, and glove box. To get a new ignition & key would create a situation where you'd have to use two different keys with different cuts to operate all the lock cylinders on your car...which goes on to be even more difficult to imagine with overcoming EWS where the key, EWS control module, DME/ECU, and Ring Antenna must all have the same matching ISN (individual serial number) in order for the car to start.

My suggestion would be to find out why the ignition barrel (tumbler) is hanging up. There have been many discussions about this over the e38 & e39 production years (they both use the same set-up as well as other BMW models during this same time period). If you get nothing doing a search here...try a GOOGLE search or even YOUTUBE. Good luck.

To replace a bad ignition'd need to order item #6 in the diagram below from a BMW the link to the online part database to see the part nbr and approx (wholsale) price):
