key cost?

I have a 1997 BMW 528i, and the key cost $204 from the dealer in Austin, TX

I looked into a replacement key for my 2001 325Ci a few years ago, and it was $250 at the dealership. That was for the integrated key and remote--note sure if they had those in 1998, too.

A factory B.M.W. key from the dealer in Murray, UT. $64.00

how much does it cost for key replacement at the dealer

At the dealer its 75$ for the key and about 15$ for overnight shipping + Taxes for a grand total of about 100$.
