Ignition lock

Hello, guys.

wanted to ask if any of you know what a new ignition lock incl. It costs installation?
Background: my ignition lock is jammed from the beginning, usually it could be jerked with a little bit and played again. Yesterday in the metro parking lot, totel failure! After half an hour I gave up and called the ADAC, which removed the lower panel and with the hammer would have been easily cut to the lock while I tried further. Then it went again! but how long?
He said it would probably be better to switch as long as it can be unlocked at all, if it doesn't unraise at all, it would probably be more expensive! Can you agree with that?
