What Do I Do If My Key Fob Dies? The Key Fob And Remote Shop Honolulu, Hawaii

When a key fob's battery dies, it can be inconvenient, but there are a few steps that you can take to resolve the issue. Here are the steps to take when your key fob stops working due to a dead battery:

  1. Identify the Key Fob: Make sure you're certain that the key fob's battery is the problem. Sometimes, other issues like a faulty key fob or a low car battery can mimic the symptoms of a dead key fob.

  2. Access the Physical Key: Most key fobs have a hidden physical key that can be used to unlock the car manually. Look for a small button or release mechanism on the key fob, and use it to extract the physical key.

  3. Unlock the Car Manually: Use the physical key to manually unlock the car's door. This allows you to access the interior of the vehicle.

  4. Replace the Key Fob Battery: The key fob's battery can usually be replaced easily. Here's how to do it:

    • Look for a small screw or slot on the key fob to open it. Some key fobs have a removable cover, while others require prying the two halves apart.
    • Once the key fob is open, locate the battery compartment. The battery type is typically indicated on the old battery or in the key fob's manual.
    • Carefully remove the old battery and replace it with a new one of the same type.
    • Close the key fob back up, ensuring it's securely sealed.
  5. Test the Key Fob: After replacing the battery, test the key fob to see if it's working. You may need to stand near the car and press the buttons to lock, unlock, or perform other functions.

  6. Reprogram (if necessary): In some cases, having a dead car battery for an extended period of time may require reprogramming the key fob to the car's security system. Consult your car's owner's manual for instructions on how to reprogram the key fob, or contact your dealership or a locksmith for assistance if your key fob is not self-programmable.

  7. Keep Spare Batteries: It's a good idea to keep spare batteries for your key fob on hand, especially if your key fob uses a common battery type. This way, you'll be prepared when the battery eventually needs replacement.

If replacing the battery doesn't resolve the issue, or if you're unable to reprogram the key fob on your own, it may be a sign of a more significant problem with the key fob itself, and you may need to consult a professional locksmith or the dealership to replace the key fob.
