Why Your Key Fob Doesn't Work After Replacing the Shell
Replacing your key fob shell is a great way to restore its look and durability, but if your key fob suddenly stops working afterward, there may be a few common reasons why. In most cases, the issue comes down to missing components, improper assembly, or accidental damage during the process. Here’s what you need to check if your key fob isn’t functioning after a shell replacement.
1. Forgetting to Transfer the Immobilizer Chip
One of the most common mistakes is failing to transfer the immobilizer chip from the old key fob to the new shell. This small but essential chip is responsible for communicating with your car’s security system. Without it, your vehicle will not recognize the key and will prevent the engine from starting.
How to Fix It:
-Open your old key fob shell and locate the small transponder chip (often separate from the circuit board).
- Carefully remove the chip and transfer it to the corresponding slot in the new shell.
- Ensure it’s securely in place before reassembling the fob.
- Watch a video guide carefully to see where the immobilizer chip is located and where to put it. In some models, the immobilizer chip is embedded in the shell itself.
2. Battery Not Installed in Correct Orientation
Another frequent issue is installing the key fob battery incorrectly. If the battery is placed in the wrong orientation, it will not provide power to the key fob, rendering it non-functional.
How to Fix It:
- Check that the battery is installed in the correct orientation (positive and negative sides aligned properly).
- If the battery appears drained, replace it with a new one.
- Ensure the battery contacts are making a secure connection inside the fob.
3. Misaligned Silicone Buttons
If the buttons on your key fob are not properly aligned within the new shell, they may not press down correctly on the circuit board, resulting in unresponsive or inconsistent functionality.
How to Fix It:
- Before closing the shell, ensure that each button is positioned correctly in its slot.
- Press the buttons a few times to confirm they have a full range of motion and make contact with the circuit board.
- If needed, adjust the positioning before snapping the shell shut.
