Signs Your Key Fob Battery Needs Replacement

- Your vehicle is increasingly difficult to start because the vehicle is having trouble sensing that the key fob is in the car.

Replacing Your Mercedes-Benz Key Fob Battery
Follow these easy steps to proactively replace your key fob battery before it kicks the bucket.
- Determine which type of key fob you have. The Chrome Key and Smart Key fobs are slightly different.
- Get the appropriate replacement battery. The Smart Key uses two 3-volt CR 2025 batteries while the Chrome Key uses just one. These are the small flat silver batteries you can find at most grocery stores and hardware stores.
- Smart Key: At the end of the key holder, pull the latch and stick your key into the open slot. Lift the battery compartment out to replace the batteries.
- Chrome Key: Pull the tab at the bottom, and push the key into the narrow end of the slot to pop off the cover and replace the batteries.
