Is your 2010 Mazda CX-7 key fob not working? The most likely culprit is a dead battery. Replacing the battery in your key fob is a simple and inexpensive fix you can do yourself. This guide will walk you through every step to get your key fob working again.
Knowing the correct battery for your 2010 Mazda CX-7 key fob is the first step. Mazda CX-7 key fobs typically use CR2025, CR2032, or CR1620 batteries. These batteries are commonly available online and at most stores that sell batteries. The good news is that a replacement battery for your key fob usually costs less than $6.
Step-by-Step Guide to Replacing Your Key Fob Battery
Whether you have a newer or older 2010 Mazda CX-7, the process to open your key fob is slightly different. Here’s how to open your key fob and replace the battery:
Opening Your Mazda CX-7 Key Fob
For newer Mazda CX-7 models, look for a hidden key within your key fob. Locate the designated slot on your key fob, and insert this hidden key into the slot. This action will help you to pry open the key fob case.
For older Mazda CX-7 models, you’ll need a thin, flat object like a flathead screwdriver. Carefully inspect your key fob for a small notch or opening. Gently insert the flathead screwdriver into this notch and twist slightly to pry the case open. Be careful not to use excessive force to avoid damaging the case.
Replacing the Battery
Once you have successfully opened the key fob case, you will see the circuit board and the battery. Gently lift the circuit board to get clear access to the battery compartment. Before removing the old battery, take a moment to note the battery’s orientation – specifically, which side is facing up. This will ensure you insert the new battery correctly.
Now, remove the old battery. Install the new battery, making sure to place it in the same orientation as the old one.
Testing Your Key Fob
After securely closing the key fob case, test its functionality. Press the buttons on your key fob to lock, unlock, or activate other features of your Mazda CX-7. If the key fob is still not working, double-check the battery placement and ensure that the battery contacts are clean and making good contact with the battery.

Understanding Key Fob Types
Key fobs come in various designs, but the battery replacement process is generally similar across types. Here are five common types of key fobs:
- Standard Remotes: Basic remotes with standard lock/unlock functions.
- Flip Keys: Keys attached to the remote that flip out, often seen in older models.
- Remote Heads: Keys that are directly attached and fixed to the remote, not retractable.
- Fobik Keys: Remotes with a separate, hidden key inside; the key and fob are not connected when separated.
- Smart Keys: Advanced remotes often associated with push-to-start ignition systems.
If replacing the battery in your 2010 Mazda CX-7 key fob doesn’t solve the problem, the issue might be more complex. In such cases, you may need to consider replacing the entire Mazda CX-7 key fob.
