Mercedes-Benz E320 High Usage Vehicles May Experience Ignition Lock and Tumbler Failures
Due to wear, high usage vehicles can experience ignition lock and tumbler failures. The ignition lock cylinder will generally require replacement to correct this concern.
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 - miglenda

Unable to get key out of ignition sometimes. It usually comes out, but it takes about half a minute. - Visitor
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? - Visitor

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. - Visitor
