What to Do When a Mercedes Car Key Runs Out of Battery?
2 Answers
When a Mercedes car key runs out of battery, simply replace the battery. To start the Mercedes car, you can also press the key against the induction area to utilize the remaining power to start the vehicle. If it still cannot start, you will have to use the mechanical key to start the car. The method to replace the Mercedes car key battery is as follows: 1. Before replacement, prepare a new battery that matches the car key battery model. The battery model is usually found in the Mercedes car key user manual. 2. Push the switch upwards from the tail of the car key, and the mechanical key will pop out. Then remove the mechanical key. 3. Next, use the just-removed mechanical key to press against the notch on the car key and pry it open with force to open the back cover of the car key. 4. After opening the back cover of the car key, first remove the old battery and then replace it with the new one. 5. Finally, close the back cover of the car key and reinsert the mechanical key.
Last time my Mercedes car key suddenly ran out of battery, which was really frustrating. First step, quickly try the spare key; if not available, Mercedes cars usually have a hidden keyhole under the driver's door or near the trunk, use the physical key to manually open the door. After opening the door, don't panic if the car won't start. Mercedes' keyless start system allows you to place the dead key close to the start button for induction start. If this doesn't work, just head to the nearest auto parts store to buy a CR2032 button battery. Replacing it yourself is simple—carefully pry open the key's back cover, remove the old battery, and replace it with the new one. Make it a habit to keep a spare battery in your bag and check the key's battery indicator light once a year. Mercedes' alert system is quite sensitive and will warn you when the battery is low. Deal with it early to avoid getting stuck on the road.
