Understanding Key Fobs and Key Fob Replication

A key fob is essentially a small, handheld device that utilizes Radio-Frequency Identification (RFID) technology. When presented to a compatible reader, it grants access to a secured area, be it a building, office, or gated community. The convenience for users is undeniable – no more searching for keys. For property managers, key fobs offer streamlined access management, allowing for remote granting or revocation of access as needed. Issuing new fobs to residents or removing access for departing ones becomes a simple, efficient process.

However, this convenience comes with a caveat: the ease of key fob replication. Basic RFID key fobs, unlike encrypted systems, can be relatively straightforward to copy. This accessibility to replication tools presents potential security vulnerabilities that are important to understand. Furthermore, like any electronic device, key fobs and cards can be susceptible to demagnetization, leading to malfunction and access issues.

How to Replicate a Key Fob: A Step-by-Step Guide

Replicating a key fob, in basic terms, involves transferring the digital information from an existing fob to a blank one. While we emphasize the security concerns and encourage exploring alternatives, understanding the replication process is important for awareness. Here’s how it’s typically done in five steps:

Setting Up the RFID Copier: The first step is to power on your RFID copier. These devices are usually handheld and designed for user-friendliness with straightforward interfaces. Ensure the device is on and familiarize yourself with the “Read” and “Write” buttons, which are central to the replication process.
Reading the Original Key Fob: Take the key fob you intend to replicate and position it closely to the scanner on the copier. The proximity needed is usually quite small, within 1 to 3 inches, but can vary by copier model. Activate the scanning process by pressing the “Read” button. The copier will then scan and capture the RFID frequency and data encoded within the original key fob.
Preparing the Blank Key Fob: Remove the original key fob from the scanner and replace it with a blank RFID tag or key fob. These blank fobs are readily available from online retailers and are generally compatible with most RFID copiers designed for standard frequency fobs.
Writing Data to the New Fob: With the blank fob in place, press the “Write” button on the copier. This command initiates the transfer of the data previously read from the original fob onto the blank one. A beep or a flashing light on the copier usually indicates a successful data transfer.
Testing the Replicated Key Fob: The final and crucial step is to test the newly replicated key fob at the intended access point. If the replication has been successful, the new fob will function identically to the original, granting access as expected.

Important Note: It’s crucial to be aware that generic, readily available key fob copiers may not work for all key fobs, especially those that are encrypted or operate on less common frequencies. For secure and reliable key fob replication, especially for encrypted systems, contacting an authorized provider or the system manufacturer for a certified copier is recommended.

Security Concerns Associated with Replicated Key Fobs

While the ability to Replicate Key Fobs can seem convenient in certain situations, it introduces significant security risks. The ease with which unauthorized copies can be made raises concerns about property access control and overall security.

Potential Security Issues:

Unauthorized Access: Replicated key fobs can easily fall into the wrong hands, providing unauthorized individuals with access to secure areas. This can lead to breaches in security, potential theft, and compromised safety for residents or building occupants.
Loss of Access Control: When key fobs are easily replicated, it becomes challenging to maintain a secure record of who has legitimate access. This weakens the entire premise of controlled access systems.
Increased Security Vulnerability: Properties relying solely on easily replicated key fobs become more vulnerable to security threats. This is particularly concerning for apartment buildings, gated communities, and commercial spaces where security is paramount.

Exploring Mobile Access: Can You Replicate a Key Fob to Your Phone?

Directly replicating a traditional key fob’s RFID signal to a smartphone is generally not possible. Smartphones do utilize NFC (Near Field Communication) technology, which is related to RFID, but they are not inherently designed to mimic or copy the specific signals of most key fobs for access control purposes.

However, the concept of using your phone as a key fob is indeed a reality through mobile access control systems. Instead of replicating a physical fob, these systems utilize smartphone apps to grant access.

Mobile Access as an Alternative:

Mobile access control systems offer a secure and convenient alternative to traditional key fobs. Companies like ButterflyMX provide systems that allow residents and authorized users to use their smartphones as digital keys. This is achieved through dedicated apps that communicate with the access control system, granting entry upon authorized verification.
