So out of the blue the key on my 1999 SLK230 (manual) won't turn in the ignition. Will turn enough to unlock the steering wheel but not enough to turn on the car. Tried my keyfob key, my spare key and my valet key to no avail. Wiggled and jiggled the key and steering wheel for ages - again no luck. Called MB dealer and we're talking over $1,000!!!! Looked online at You Tube and watched loads of videos (apparently it's not an uncommon problem) and finally found this one....that sounds like it might work but it's a little scary....don't want to screw anything up...
Opinions? Would sure appreciate any advice.
