My 91 735i driver's door won't open

Hi guys,

When I inser the key to open the driver's door, it won't open/rotate completely. The other doors open just fine, except the lock at the driver's door gets a little stock (it won't go all the way up). Any suggestions/fixes?

Thank you in advance!!

The support beam for the lock solenoid is famous for cracking and allowing the solenoid to get misaligned. You need to pull the inner door panel and take a look. Here is a great site for this and other repairs (with pictures): Johan and Sean's site.
