Understanding Key Fobs: Convenience and Cloning
A key fob is essentially an RFID (Radio-Frequency Identification) credential. You gain property access by presenting this fob to a reader. For residents, key fobs are incredibly convenient, eliminating the need to handle traditional keys. They simply wave or tap their fob to gain entry.
Property managers also find key fobs advantageous. Access permissions can be managed remotely, making it simple to issue fobs to new tenants and deactivate them when necessary. This remote management adds a layer of administrative ease compared to traditional key systems.
Despite these benefits, a significant drawback of basic key fobs is their susceptibility to being copied or cloned. Furthermore, physical key fobs and cards can be demagnetized, leading to malfunctions and access issues.
Step-by-Step: How to Copy a Key Fob
Copying a key fob, in theory, can be a straightforward process using readily available RFID copier devices. Here’s a typical five-step procedure:
-
Prepare Your RFID Copier: Begin by powering on your RFID copier. These devices are generally user-friendly, featuring simple interfaces and clear instructions. Ensure the device is on and identify the “Read” and “Write” buttons, which are crucial for the copying process.
-
Initiate the Reading Process: Take the original key fob that you intend to duplicate and hold it in close proximity to the scanner on the copier. The reading range is usually short, around 1 to 3 inches depending on the specific model of the copier. Press the “Read” button on the device. The copier will then scan and capture the RFID frequency and data encoded on the original fob.
-
Prepare a Blank Key Fob: Remove the original key fob and replace it with a blank RFID tag or key fob. These blank fobs are widely accessible for purchase online and are designed to be compatible with most standard RFID copiers.
-
Write Data to the New Fob: Press the “Write” button on the copier. This action initiates the transfer of the data that was just read from the original fob onto the blank fob. The copier will usually provide an indication of successful data transfer, such as a beep or a flashing light.
-
Test the Duplicated Fob: Finally, it’s essential to test the newly copied key fob at the intended access point. If the duplication has been successful, the new key fob should function identically to the original, granting you access.
Important Note: While generic key fob copiers are available, many modern key fobs, especially those used in secure residential or commercial buildings, are often encrypted. Using a generic copier might not work for encrypted fobs. For encrypted systems, always consult the manufacturer for authorized duplication methods or replacements.
Can You Copy a Key Fob to a Phone? Exploring Mobile Options
Directly copying a traditional key fob’s signal to a phone is not feasible. Your smartphone doesn’t inherently possess the hardware to directly replicate RFID signals in the way a dedicated RFID copier does.
However, there are workarounds and more advanced solutions. One option is to use an RFID sticker. You can program an RFID sticker with the copied key fob data and then attach this sticker to your phone. This effectively allows your phone to act as a key fob when tapped against a reader.
A more sophisticated and increasingly popular approach is to utilize mobile access control systems. These systems are designed to leverage smartphones as keyless credentials directly.
Using Your Smartphone as a Key Fob: Mobile Access Control
Yes, with a modern mobile access control system, you can indeed use your smartphone as a key fob. Systems like ButterflyMX offer smartphone-based access that provides a significant upgrade in both convenience and security compared to traditional key fobs and key cards.

Key Fob Copying: FAQs and Security Considerations
Is copying key fobs illegal?
Generally, copying a key fob is not illegal if you are the legitimate owner of the fob. However, ethical and security considerations are paramount. Unauthorized duplication, especially for malicious purposes or gaining unauthorized access, can have legal repercussions. While copying your own fob for personal convenience might be acceptable, creating copies for others without authorization is a security risk.
What is the typical cost to copy a key fob?
The cost to duplicate a key fob can vary widely depending on factors like the fob type (basic vs. encrypted), the service provider (DIY kits vs. professional locksmiths), and geographic location. Professional key fob copying services can range from approximately $150 to $500. Basic DIY copiers and blank fobs are cheaper upfront but may not work with encrypted fobs and require technical understanding.
Can a locksmith duplicate key fobs?
While not all locksmiths are equipped for key fob duplication, many modern locksmiths are adapting to this demand. Some now offer key fob copying services, utilizing RFID copiers and blank fobs to replicate basic RFID keys. However, for encrypted or more complex systems, specialized services or authorized providers might be necessary.
Are key fobs typically programmed?
Yes, key fobs are programmed with unique identification codes during manufacturing. This programming and often encryption ensures that each fob is distinct and authorized only for specific access points. This prevents a generic fob from opening unauthorized areas.
What are the differences between RFID and NFC key fobs?
The primary difference lies in communication capability. RFID key fobs typically operate on one-way communication, simply transmitting their ID to a reader. NFC (Near Field Communication) fobs, in contrast, support two-way communication and can store more complex data. NFC is generally considered a more advanced and secure technology than basic RFID, often used for applications requiring data exchange and higher security levels.
