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?
Inserting key does not unlock the ignition. I have Googled till my eyes bled and all I can come up with for sure is I either need a new key fob $300+ or replace entire ignition system $1200+!OUCH! Currently Unable to even afford the tow to the MB Stealership let alone the key! Stranded and collecting dust...
Key will turn once in awhile when you hear a electronic click sound it will start. Otherwise sticks when key inserted will not turn to start. Where can I find a new Ignition key tumbler & How to fix it instructions?
I put in the key sometimes it doesn't engage then you have to pull it out put it back in and then the electronic key will engage and then sometimes you can turn the car over and then sometimes you can't when you can turn the car over it doesn't always start you have to do this a few times. Can I order this past somewhere. I need the one with the electronic key.
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.
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
The key stop communicate with the car. I use a regular key to open the door, the car's alarm activevated for few minutes (each time I open the door). The key cannot turn the ignition to start the car anymore
Unable to get key out of ignition sometimes. It usually comes out, but it takes about half a minute.
I believe there was a light bulb malfunction and I thought I fully turned my car off but come to find out it did not turn off now I can't start my car and even turn the ignition
Car ignition won't turn over. I insert key and it remains at starting point in ignition switch where system message say to "Remove Key". Called dealer 9/10/15 and they said I have to tow vehicle to dealer and pay $340 plus tax to purchase new key. Cost is for one key only. It will take 2 business days for key to arrive to dealer.
i bought a 96 e320 and the previouse owner tore the ignition apart, now i have to put the key in the round silver part that is laying on the dash board where my mph is and i have to use this mock up key type thing now my problem is i can turn my car over but it wont start,ive done the code on the radio, ive re synced my key it will start every now and then do i need to replace my ignition and keys?
