Hey new here...
I have an 1990 Mercedes 190E sportline. I have got the common problem with the lock jamming, key wont turn at all to the NR 1 position..
Its really frustrating. I know a guy who used to be a mercedes mechanic. He told me the only way is too keep turning the key and eventually it would move.. Coult take hours though.
Ive been sitting about 5 hours now and nothing happens!
What im wondering is if some smart person in here has any tip of any kind!
Anything that can help cause its my first car and all that and all i see is it standing still
Im also wondering IF i can get the key to turn and pop out the lock cylinder, will the problem be solved if I just switch the lock cylinder? Or do I have to switch the entire lock?

Thanks heaps for any help!
