Here are some steps you can try to resolve the issue of the key getting stuck in the ignition of your 1995 E320:
1. Check the Shift Interlock System:
- Ensure the car is in "Park" position. Some vehicles have an interlock system that prevents the key from being removed unless the gear selector is in the "Park" position.
2. Check the Steering Wheel Position:
- Try turning the steering wheel slightly left and right while attempting to remove the key. Sometimes, the steering wheel may need to be in a certain position to allow the key to be released.
3. Inspect the Key:
- Examine the key for any signs of damage or deformation. If the key is damaged, it may not be able to properly engage the ignition switch.
4. Try Spare Key (If Available):
- If you have a spare key, try using it to see if the issue persists. This can help determine if the key is the cause of the problem.
5. Check the Ignition Cylinder:
- There might be an issue with the ignition cylinder itself. If the key is difficult to insert or turn, or if it feels loose, the cylinder may need to be repaired or replaced.
6. Gearbox Connection:
- While it's unusual for gearbox issues to directly affect the key getting stuck in the ignition, you mentioned a potential connection. It's worth having the gearbox inspected by a qualified mechanic to rule out any related problems.
7. Professional Help:
- If the above steps don't resolve the issue, it's best to seek the assistance of a qualified mechanic or automotive locksmith who can accurately diagnose and fix the problem.
Remember, safety is paramount. If the key is stuck and the car is in gear, do not attempt to force the key out or start the vehicle. Consult a professional to avoid causing any further damage to the ignition system or other components.
