Remove Old Battery
To remove the old battery, follow these detailed steps:
1. Ensure that the key fob is facing you, with the buttons facing upwards.
2. Locate the small, recessed button on the bottom edge of the key fob. It may be hidden by a small rubber cover.
3. Press and hold the recessed button while gently pulling the back cover of the key fob away from the front. The back cover should slide out easily.
4. Once the back cover is removed, you will see the old battery. It is usually held in place by a metal clip or a small plastic tab.
5. Carefully remove the old battery by gently prying it out of its holder. Avoid damaging the contacts or the battery itself.

1. Once the back of the fob is open, locate the battery. It will be a small, round battery with a positive (+) and negative (-) terminal.
2. Use a small screwdriver or your fingernail to gently pry the old battery out of the fob.
3. Insert the new battery into the fob, making sure that the positive (+) terminal is facing the right way.

Polarity Check
Before replacing the battery, it’s crucial to ensure you insert the new battery with the correct polarity. Incorrect polarity can damage both the battery and the key fob. Here’s how to determine the battery’s polarity:
- Examine the battery’s terminals. One terminal is usually slightly raised with a small dot or plus sign (+) indicating the positive terminal. The other terminal is usually flat or concave with a minus sign (-) indicating the negative terminal.
- Align the battery with the terminals in the key fob. The positive terminal of the battery should align with the positive terminal in the key fob, and the negative terminal of the battery should align with the negative terminal in the key fob.
- Gently press down on the battery to ensure it is securely in place. Do not force it if it doesn’t fit snugly, as this could indicate incorrect polarity.
- Once the battery is correctly inserted, test the key fob to ensure it is functioning properly.
| Positive Terminal | Negative Terminal |
|---|---|
| Raised with a dot or plus sign (+) | Flat or concave with a minus sign (-) |
