What Will You Need?
Before we begin, make sure you have the following items:
- HID Prox Key Fob: This is the physical device that will be used to gain access.

9 Easy Steps on How to Use Hid Prox Key Fob
Step 1. Locate the Prox Card Reader:
Begin by identifying the prox card reader at the location you wish to access. These readers are usually installed near doorways, gates, or entry points that require controlled access. Look for a small rectangular device that resembles a scanner, often mounted on a wall or door frame. Ensure that the reader is powered on and operational—most readers will have an LED indicator or display to show they are active. Familiarizing yourself with the appearance and placement of the device will save time when you need to access the area efficiently.

Step 2. Hold Your HID Prox Key Fob Near the Reader:
Hold your HID Prox key fob close to the prox card reader. Typically, you need to position the fob within a few inches of the reader’s surface for it to detect the signal. You may hear a beep or see a light change on the reader, indicating that the fob has been recognized. Hold it steady for a moment to ensure proper communication between the fob and the reader. This process should be quick and seamless if the system is functioning correctly.
Step 3. Wait for Access Confirmation:
Wait for the system to confirm your access after the reader recognizes your HID Prox key fob. This is usually indicated by an audible sound, such as a chime or beep, and/or visual signals, like a green light on the reader. Some systems may trigger the unlocking mechanism immediately, allowing you to open the door or gate. If you do not receive confirmation, double-check the placement of your fob and ensure it is functioning correctly before attempting again.
Step 4. Troubleshooting Issues:

If your HID Prox key fob fails to grant access, there are a few troubleshooting steps you can take. First, ensure that your fob is in good condition, as damaged or worn-out fobs may not function correctly. Check the reader for any visible debris or obstructions that could interfere with the signal. It’s also possible that your fob’s credentials need to be updated or reprogrammed; in such cases, contact the appropriate administrator or security personnel for support. If the issue persists despite these efforts, the problem may lie with the system, requiring maintenance or technical assistance. Always report recurring issues to ensure the system remains functional and secure.
Step 5. Replacing Your HID Prox Key Fob:
If your key fob is lost, damaged beyond repair, or no longer functional, obtaining a replacement is essential to maintain access. Contact your facility’s management or security team to request a new fob. Depending on the protocol, you may need to provide identification or complete a formal request form. Keep in mind that replacement fobs may incur a fee. Once you receive your new fob, ensure it is programmed and activated before use. Safeguard your new fob by storing it securely and avoiding exposure to extreme conditions or physical damage.
Step 6. Returning a Key Fob:
If you no longer require using an HID Prox key fob—for instance, when leaving a facility or after your authorized access period—it is essential to return it promptly. Contact the facility’s management or security team to arrange the return process. Ensure the key fob is in good condition to avoid penalties or replacement charges. Returning the fob helps maintain the integrity of the access system and ensures that access is not left unauthorized.

Step 7. Replacing a Lost or Damaged Key Fob:
If your HID Prox key fob is lost or irreparably damaged, it’s essential to report the issue immediately to the facility’s management or security team. This step ensures they can deactivate the missing fob to prevent unauthorized access. Most facilities have a protocol for replacing key fobs, which may involve filling out a request form or paying a replacement fee. Ensure you provide accurate information during the process to expedite the replacement. Upon receiving the new key fob, test it at the access points to confirm it works as expected. Always handle your replacement fob carefully to avoid future issues.
Step 8. Proper Maintenance of Your Key Fob:
To ensure the longevity and functionality of your HID Prox key fob, it’s essential to practice proper maintenance. Keep your key fob away from extreme temperatures, excessive moisture, and direct sunlight, as these elements can damage the internal components. Avoid dropping or bending the fob, as physical impacts may cause it to malfunction. Clean your key fob occasionally with a soft, dry cloth to remove dirt and dust buildup. Regular maintenance can help prevent unexpected issues and extend the life of your key fob, ensuring reliable performance over time.
Step 9. Additional Uses for Your HID Prox Key Fob:
Aside from physical access control, your HID Prox key fob can also be used for other purposes, depending on your facility’s system capabilities. Some systems may allow you to use your fob as a time clock or attendance tracker, granting entry based on specific schedules or tasks assigned to the fob. In some cases, it can also serve as a form of payment or identification within the facility. Consult your facility’s administration or security team to explore other potential uses for your HID Prox key fob and maximize its features.

By following these steps and tips, you can confidently use your HID Prox key fob for secure and convenient access to various facilities.
