Signs of a Faulty Car Key

  1. Key fob malfunction: If your key fob stops working, such as failing to lock or unlock the car, it may indicate a problem with the key itself or the fob's battery. Replacing the battery is a simple fix, but if the issue persists, it might be time for a new key.

  2. Key jamming: Difficulty turning the key in the ignition or experiencing frequent jams is another sign of potential trouble. This could be due to general wear and tear, dirt accumulation, or internal damage to the key. If you're encountering persistent key jamming issues, it's worth considering a replacement.

  3. Physical damage: Physical damage to the key, such as a cracked or bent key blade or broken buttons on the key fob, can compromise its functionality. While minor scratches or scuffs may not be cause for concern, significant damage may necessitate a replacement to ensure reliable operation.

  4. Unresponsive key: If your key becomes unresponsive, meaning it doesn't start the car or trigger any response from the vehicle, it's a clear indication that something is wrong. First, try replacing the battery in the key fob, but if that doesn't resolve the issue, it's advisable to seek a replacement key.
