What to Do When a Mercedes Key Fob Battery Dies?
2 Answers
When a Mercedes key fob runs out of battery, simply replace the battery. The specific steps are as follows: 1. Slide the small toothed switch at the end of the key fob to the right, which will release the manual key. 2. Pull out the key and gently insert it into the hole behind the key slot to engage with the battery cover latch. Gently pry it open to remove the cover. 3. Once opened, the battery will be visible. 4. Press lightly on the battery to pop it out, replace it with a new one, and then close the key cover. Here are some important notes: 1. Different vehicle models may have different methods for opening the key fob. 2. Generally, replacing the battery as soon as it starts to run low can prevent many inconveniences.
Don't panic when your Mercedes key fob runs out of battery—I've been there too. First, find a small pointed object to remove the mechanical key. Pry open the small cover behind the door handle and insert the key to unlock the door. Once inside, place the key fob near the start button, and the dashboard will indicate that the key is recognized. Then, press the start button while holding the brake to ignite the engine. Afterwards, quickly grab a CR2032 coin cell battery from a convenience store or online. The key fob has clips on the side—use your fingernail or a small screwdriver to pry it open and replace the battery, making sure the positive side faces up. It's wise to keep a couple of spare batteries in your car's glove box; I always stash two in the center console—they saved me during a sudden downpour when my key died. Also, don't forget your spare key; alternate between the two to avoid both failing at the same time.
