Copying a key fob can be a convenient way to grant access to family members, roommates, or employees. However, if your copied key fob isn’t working properly, it can be frustrating. Fortunately, there are ways to diagnose and fix the issue.

In this guide, we’ll walk you through common reasons a copied key fob might not work and troubleshooting steps to resolve the problem. Whether you used a key fob copier at a local shop or an online service, this article will help you find a solution.

Common Reasons Your Copied Key Fob Isn’t Working

If your copied key fob isn’t unlocking doors or granting access as expected, here are some possible reasons:

1. Incorrect Frequency or Encryption

Most key fobs operate on different frequencies (e.g., 125kHz or 13.56MHz) and may have encrypted codes. If the fob was copied onto a chip that doesn’t match your original fob’s technology, it won’t work.

2. Poor Copy Quality

If the duplication process wasn’t done correctly or the equipment used was outdated, the new key fob might not be an exact match to the original.

3. Dead or Weak Battery

Some key fobs require a battery to function. If the copied fob has a weak or dead battery, it won’t transmit a signal properly.

4. Building or System Restrictions

Some buildings have security measures that prevent cloned fobs from working. Property managers may use rolling codes or blacklist unauthorized copies.

5. Interference from Other Devices

If there are other electronic devices nearby (such as Wi-Fi routers or other RFID-based systems), they could interfere with your key fob’s signal.

6. Copied Fob Needs Activation

Some key fobs need to be activated within the building’s access system before they start working.

How to Troubleshoot a Non-Working Copied Key Fob

If your copied key fob isn’t working, try these troubleshooting steps before replacing it:

1. Check the Battery (If Applicable)

  • If your key fob has a replaceable battery, open the casing and check if the battery is working.
  • Replace it with a fresh battery and test the fob again.

2. Test the Original Key Fob

  • Ensure your original key fob is still functional.
  • If the original fob is not working, the issue might be with the building’s access system, not the copied fob.

3. Verify the Fob’s Frequency

  • If possible, confirm that the copied key fob operates on the same frequency as the original one.
  • If they don’t match, the copied fob won’t work.

4. Reattempt Copying with a Reliable Key Fob Copier

  • If the copied fob isn’t working, you may need to duplicate it again using a high-quality key fob copier.
  • Some services offer re-copying for free if the fob doesn’t work the first time.

5. Check for Signal Interference

  • Move away from large metal objects, electronic devices, or Wi-Fi routers that might block the signal.
  • Try using the key fob closer to the reader to see if it improves response.

6. Ask Building Management About Security Features

  • Some buildings have advanced security systems that block copied key fobs.
  • Contact your building management or security team to check if your fob needs to be registered in their system.

7. Try a Different Key Fob Chip Type

  • If your copied fob isn’t working, the chip type may be incompatible.
  • Some key fob copiers can transfer the data to a different type of fob chip that may work better.
