How to Open the Door with the Mechanical Key of Mercedes-Benz E300L?

[OAddyson]

Insert the mechanical key directly into the keyhole on the door to open or lock the car door. There is usually a hidden keyhole in the armrest box or under the cup holder. Locate the keyhole near the steering wheel, insert the mechanical key, and you can start the car in the traditional way. If it's a conventional folding key, it is usually visible, and the mechanical key can be accessed by pressing a button or similar method. Another type is the mechanical key that is usually hidden within the main key and not visible. To access this key, you need to open the safety latch on the key before pulling it out.
