Have Mercedes Questions? Ask a Mechanic for Answers ASAP
Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.
Is the blade key turning in the cylinder at all in either direction?
Let me know so we can continue,thanks Pete.
O.k.,in some cases the cylinder can bind when turning with the metal key blade due to lack of use.Try spraying a small amount of lubricant into the cylinder hole then let it sit for about an hour then try and work the key in the cylinder hole to release the lock to then open the door so the battery can be accessed to be re charged or replaced.
If this does not work you will either have to have mercedes roadside assistance come out and unlock it with their tools as they can in some cases or a lock smith or AAA company will have to come out and unlock it with their tools as this is usually the only other option.
