Here's a breakdown of how to approach this, starting with the safest and least invasive methods:
1. Try the Obvious (But Important):
* Steering Wheel: Make absolutely sure the steering wheel is not slightly turned. Even a slight turn can engage the steering lock, preventing key removal. Gently wiggle the wheel while trying to remove the key.
* Gear Shift: Ensure the gear selector is in the "Park" position (P). Some automatic transmissions won't release the key unless in Park.
* Brake Pedal: Some Mercedes models may require the brake pedal to be depressed.
* Key Position: Double-check the ignition is fully in the "Off" position.
2. If the Above Doesn't Work:
* Try a Different Key: If you have a spare key, try that. This helps determine if the problem lies with the key itself or the ignition system.
* Lightly Tap the Ignition: Gently tap the area around the ignition switch with the palm of your hand. Sometimes, a slight jarring can release a stuck mechanism. Avoid using anything hard or metallic.
3. If Still Stuck - Professional Help is Needed:
If none of the above works, you need professional help. Attempting further DIY solutions could cause significant damage. Contact:
* Mercedes-Benz Roadside Assistance: If you have a warranty or roadside assistance plan, this is your first call. They are equipped to handle this type of situation.
* Locksmith: A qualified automotive locksmith specializing in Mercedes vehicles will have the tools and expertise to safely remove the key and diagnose the underlying problem. Be cautious and ensure you choose a reputable locksmith.
* Mercedes-Benz Dealership: This is the most expensive option, but it guarantees expertise and genuine parts should repairs be needed.
Important Considerations:
* Avoid using WD-40 or other lubricants: These can gum up the ignition mechanism and make the problem worse.
* Don't force the key: This is crucial. Forcing it will almost certainly cause damage.
Getting professional help is the best approach. The cost of repair from damaging the ignition switch will far outweigh the cost of calling a locksmith or roadside assistance.
