Identifying Your Key Fob Type

Mazda CX-5 models have two main types of key fobs: the standard key fob and the proximity key fob. The standard key fob has physical buttons to lock, unlock, and open the trunk, while the proximity key fob has touch-sensitive buttons and allows keyless entry. Identifying your key fob type is crucial as the battery replacement process may vary slightly for each type.

Step-by-Step Instructions for Standard Key Fob

1. Locate the Key Release Button: On the back of the key fob, you’ll find a small button marked with a key symbol. Press this button to release the key from the fob.
2. Separate the Key from the Fob: Once the button is pressed, the key will pop out slightly. Gently pull on the key to detach it from the fob.
3. Open the Fob Case: Use your fingers or a small screwdriver to carefully pry open the fob case. There will be a seam on the side of the fob where you can insert your tool.
4. Locate and Remove the Battery: Inside the fob, you’ll see the battery. It’s usually a small, round lithium-ion battery.

6. Reassemble the Fob: Place the fob case back together and snap it shut. Make sure it’s securely closed.
7. Reinsert the Key: Align the key with the slot on the fob and push it in until it clicks into place.
8. Test the Fob: Press the lock and unlock buttons on the fob to confirm that it’s working correctly.

Step-by-Step Instructions for Proximity Key Fob

1. Locate the Battery Cover: On the back of the proximity key fob, you’ll find a small, rubberized cover marked with a battery symbol.
2. Remove the Battery Cover: Use your fingernail or a small screwdriver to pry open the battery cover. It should come off easily.
3. Locate and Remove the Battery: Inside the battery compartment, you’ll see the battery. It’s usually a small, rectangular lithium-ion battery.
