Step-by-Step Battery Replacement

1. Remove the Internal Key

First, push down the button on the key fob to release the internal key. Pull the key out and set it aside.

You’ll notice a hole where the key was, and beneath it, a groove. This groove is crucial for opening the key fob.

2. Open the Key Fob

Insert a flathead screwdriver into the groove. Hold the key fob firmly and twist the screwdriver to separate the two halves of the key fob.

If needed, work your way down the groove, twisting or pulling apart the halves with your fingers. Be gentle to avoid damaging the key fob.

3. Remove the Old Battery

Once the key fob is open, you’ll see the CR2032 battery. It may be snugly fitted, making it difficult to remove with your fingers.

Use a precision screwdriver to pry the battery out from the sides. Alternatively, a thin object like a toothpick can also work.

4. Insert the New Battery

Take the new CR2032 battery and ensure the positive side, marked with the battery information, is facing down. Push the battery into the metal component first, then press down the top until it clicks into place.

5. Reassemble the Key Fob

Align the two halves of the key fob and press them together until they click into place. Reinsert the internal key into its slot.

Test the key fob by pressing a button. If the light turns on, the battery replacement was successful.
