Mercedes-Benz car key can still work after being washed with water. Solution for water ingress: After the key gets wet, first use a dry cloth or paper towel to wipe the surface clean, remove the battery to wipe off water, and use paper to absorb water from the button gaps; then use a hair dryer to dry it or let it air dry naturally. Remember not to dry it in the sun or with hot air, as this may affect the key. How to use a Mercedes-Benz car key: Press and hold the lock button to close all windows and lock the car simultaneously. Press and hold the unlock button to unlock the car and lower all windows at the same time. Aim the key at the left front door handle of the car, keeping the distance close (within one meter), and press the lock button to automatically raise all the car's windows and close the sunroof.
