I think I need a new ignition lock tumbler. The key won't start the car, or it is hard to start sometimes.
点火密钥难以转动并在点火开关中绑定还是没有开始问题?这点火锁cylinder would need to be looked at first to see if it is the cause of your problem and a diagnosis would need to be done. Some ignition parts may require very specialized Mercedes tools to replace and program to work properly. I would recommend a certified Mercedes mechanic or an certified mechanic from YourMechanic to check it out for you.
