Step-by-Step Instructions to Open a Mazda Key Fob

1. Remove the Auxiliary Key

Locate the auxiliary key button on the back of your key fob. This is typically a small, recessed button.

  • Press this button to release the metal auxiliary key.
  • Important: This key can be used for manual entry into your vehicle if the fob battery dies.

2. Identify the Opening Slot

With the auxiliary key removed, inspect the edges of the key fob for a small slot or opening along the seam where the two halves of the casing meet.

  • This slot is where you will insert a flathead screwdriver.

3. Pry Open the Key Fob Case

Using a small flathead screwdriver, gently insert it into the slot identified in the previous step.

  • Important: To avoid scratching your fob, consider wrapping the tip of your screwdriver with tape.

  • Twist or pry gently to begin separating the two halves of the case. Start at one point and carefully work your way around the seam, applying gentle pressure.

4. Accessing Internal Components

Once you have successfully opened the case, you will have access to the internal components, including the battery.

  • If you are replacing the battery, note that most Mazda key fobs use either a CR2025 or CR1616 battery, depending on your model.

5. Reassemble the Key Fob

After replacing the battery or completing any necessary repairs:

  • Align both halves of the case and press them together until they snap back into place.
  • Reinsert the auxiliary key into its slot.
