Tumbler -lock failure Very important: The first time you have a problem teying to turn the key get it repair ASAP. The ignignition key has to be 'on'position in order to remove the tumbler which is a 15 mintute job. IF you leave it to the point as to where you can not turn- BIG JOB- They them habe to drill the thing out and it is not an easy process due to the bullet prove material Benz uses to differ theft. The most in expensive way to do it is to purchase an after market tumbler which comes comple with 2 keys. I paid $35.00 for mine online. Again ..Ve!ry iimportant that you repair at the first sign change it

I drove to work, parked and when I tried to start the car to leave the key would not turn. I tried to move the steering wheel while turning the key, but that did not help. I purchased a new ignition lock cylinder, but cannot find instructions on how to change the part. I believe the key needs to be turned to get the old one out. Can anyone help?

The car won't start and the key can not be inserted
$1800+ to repair. Very costly and lengthy repair. Even the dealership didn't want to do it!
ignition lock and tumbler willnot turn
key would not turn in cylinder.. had to replace. $750.00
Had the ignition tumblers portion replaced for about $350. However, was only given 1 key.
smart key won't unlock steering wheel, takes multiple attempts/time to unlock it and start car. Happening with increased frequency. Purchased new key from dealer but was temporary fix. Worried that it might require EIS replacement for $1500
Key wont turn. Took switch out to take to dealer as no one wants to work on these. Looking to bypass switch as this is rediculous crappy to leave a lady with two kids under 7 stranded because car ignition will not turn.
new key made car will not start
key wont turn in the ignition .Steering in locked
ignition switch, locked an will not allow the computer chip key to turn . can I fix my self.
Wife left inside lights on and drained the battery. Car would not rev past 1500 rpm. Hooked up obd II scanner and cleared codes. All was fine. Wife left lights on AGAIN and killed battery. Again car would not rev past 1500 rpm. She parked the car to wait for me to clear the codes again. Turned car off and removed key. When I went out to clear codes key would not turn switch. Thinking possibly when she removed the key she was not very gentle with it. WD 40 didn't help. I guess I am going to learn how to replace the tumblers in a MB. Lucky me.
