A dead key fob battery can be a real pain, especially when you’re trying to get somewhere on time. Fortunately, replacing the battery in your 2007 Mercedes ML320 key fob is a relatively simple process that you can do yourself with just a few tools.
What You’ll Need
- Small flathead screwdriver
- New CR2032 battery
Step-by-Step Guide
-
Locate the release button on the back of your key fob. It’s a small, rectangular button usually located near the bottom.
-
Press the release button and simultaneously slide the back cover off the key fob. You might need to apply a bit of pressure to get it started.
-
Identify the old battery. It’s a small, round, silver battery that should be clearly visible once you remove the back cover.
-
Carefully pry out the old battery using the flathead screwdriver. Be gentle so as to not damage the key fob itself.
-
Insert the new CR2032 battery, positive side facing up. Make sure it’s properly seated in the compartment.
-
Align the back cover with the key fob and snap it back into place. You should hear a click when it’s secure.
Testing Your Key Fob
After replacing the battery, test all of your key fob’s functions – lock, unlock, panic button – to make sure it’s working properly. If not, double-check that the battery is correctly installed and that the contacts are clean.
Troubleshooting Tips
- If your key fob still doesn’t work after replacing the battery, the battery itself might be dead. Try a different brand or purchase from a reputable retailer.
- Corrosion on the battery contacts can prevent the key fob from functioning properly. Clean the contacts gently with a cotton swab and rubbing alcohol.
- In some cases, you may need to reprogram your key fob after replacing the battery. This can usually be done by following a specific sequence of steps outlined in your owner’s manual.
