What to Do When the Mercedes Key Fob Battery Dies?

[MacAbel]

When the Mercedes key fob runs out of battery, simply replace the battery. The specific steps are as follows: 1. Push the small toothed switch at the end of the key fob to the right, which will pop up the manual key. 2. Pull out the key and gently insert it into the hole behind the key slot. This will touch the latch of the battery cover. Gently pry it open to remove the cover. 3. Once opened, the battery will be visible. 4. Then, lightly press the battery to pop it out, replace it with a new one, and close the key cover. Note the following: 1. Different car models may have different methods for opening the key fob. 2. Generally, replacing the battery when it is almost dead can save a lot of trouble.
