If you’re experiencing issues with your Mercedes key fob, such as decreased range or unresponsive buttons, it might be time to replace the battery. Luckily, this is a quick and easy process that you can do yourself in minutes without any special tools or skills. This guide will walk you through the steps of how to replace the battery in a Mercedes key fob, ensuring your key fob is back to working order in no time.
Identifying Your Mercedes Key Fob Type
Before you get started, it’s important to identify the type of key fob you have. Mercedes has used a variety of key fob designs over the years. The process of changing the battery is generally the same, but the type of battery and the way you access it may vary slightly.
Here are some common Mercedes key fob types:
- Chrome Key Fob: This type has a chrome metal piece that flips out.
- Smart Key: This key fob, sometimes called a keyless-go key, has a smooth, rectangular design. It may have a panic button on the back.
- Older Style Key Fobs: These key fobs vary in design but are often larger and more rectangular than the newer models.

Once you’ve identified your key fob type, you can gather the necessary materials.
What You’ll Need
- A small flat-head screwdriver or a plastic pry tool: This is used to separate the key fob casing.
- A new battery: The type of battery will vary depending on your Mercedes model. Common types include CR2025 and CR2032. You can find the correct battery type in your owner’s manual or by searching online for your specific Mercedes model.
How to Replace the Battery
Once you have your tools and new battery, follow these steps to replace the battery in your Mercedes key fob:
- Locate the battery compartment: The battery compartment is usually on the back of the key fob.
- Open the key fob: There’s typically a small slot or notch where you can insert your flat-head screwdriver or plastic pry tool. Gently pry open the casing. You may feel slight resistance, but it should open easily.
- Remove the old battery: Carefully remove the old battery from the compartment. Note the orientation of the battery, as you’ll need to insert the new one the same way.
- Install the new battery: Place the new battery into the compartment, making sure it’s facing the correct direction.
- Close the key fob: Align the two halves of the key fob and press them together until they snap shut.
- Test the key fob: Make sure all the buttons are working properly.
