Is your 2016 Mazda 6 key fob acting a little sluggish? Are you experiencing intermittent lock/unlock issues or reduced remote start range? Before you schedule a service appointment or call a locksmith, you may just need a simple battery replacement. Learning how to change the battery in a 2016 Mazda 6 key fob is a quick and easy DIY project that can save you time and money.
Understanding Your Key Fob
The key fob is a transmitter that sends signals to your Mazda 6, allowing you to remotely lock and unlock doors, open the trunk, and even start the engine. This handy device is powered by a small battery, and just like any battery, it will eventually lose its charge.
Gathering Your Tools
Before you get started, gather the following:
- A new CR2025 battery (available at most supermarkets, electronics stores, and auto parts shops)
- A small flat-head screwdriver
- A plastic pry tool or a fingernail
2016 Mazda 6 Key Fob Battery Replacement: A Step-by-Step Guide
Changing the battery in your 2016 Mazda 6 key fob is a straightforward process. Here’s how to do it:
-
Locate the Key Release Button: On the back of your key fob, you will see a small button. This is the key release button.
-
Release the Emergency Key: Press the key release button and gently slide the emergency key blade out of the fob.
-
Open the Fob Casing: With the emergency key removed, you’ll notice a small slot. Insert your flat-head screwdriver (or plastic pry tool) into this slot and gently pry open the two halves of the fob casing. Be careful not to use excessive force as this could damage the casing.
Opening the 2016 Mazda 6 Key Fob
-
Remove and Replace the Battery: Inside the fob, you’ll see the CR2025 battery. Note the battery’s orientation (+ side up). Carefully remove the old battery and install the new one in the same orientation.
-
Reassemble the Fob: Align the two halves of the key fob casing and press them together until they snap securely back into place.
-
Reinsert the Emergency Key: Slide the emergency key blade back into its slot on the fob until it locks in.
-
Test Your Key Fob: Verify that all buttons (lock, unlock, trunk release, panic) are functioning correctly. If not, recheck the battery installation and ensure it’s properly seated.
Troubleshooting Tips
If you’re still having issues with your key fob after replacing the battery, here are a few additional things to consider:
- Check the Battery: Ensure you’ve installed a fresh, unexpired CR2025 battery and that it’s oriented correctly in the fob.
- Reprogramming: In some instances, a key fob may need to be reprogrammed to the vehicle after a battery change. This is uncommon for a 2016 Mazda 6, but if you’re still encountering issues, consult your owner’s manual or contact a Mazda dealership for guidance.
- Additional Issues: If a battery replacement doesn’t resolve your issue, there may be a more significant problem with the key fob itself, such as internal damage or a faulty component. In these cases, it’s best to consult a qualified automotive locksmith or your Mazda dealership for further diagnosis and repair.
