Key fobs are small yet powerful electronic remote keys that allow entry into electronically restricted facilities and devices securely. Learn more about how they work and keep them protected against risks here.
A key fob is a small physical device that provides access to a house, building, or car. The key fob is programmable to allow someone entry to authorized areas like buildings. The device in this setup acts as a person’s identification whose access can be activated or deactivated.
Key fobs allow hands-free, keyless entry. The handy device replaces traditional keys to access a matching car or office door, as programmed.
For building managers, office managers, and business owners, implementing a keyless system with fobs is a practical solution for managing and controlling people’s entry into and exit out of their premises.
Car owners use fobs to quickly and conveniently lock and unlock their vehicles without keys and from a distance. They also use the key fobs to start the engine, open the trunk, set off the car alarm, and activate other functions.
A key fob uses RFID or radio frequency identification technology. RFID refers to a wireless, contactless communication system that uses radio frequencies to track and identify objects with tags attached to them.
It mainly requires two things for an RFID system to work:
RFID tags operate on low, high, or ultra-high frequencies, as governing authorities allow for RFID key fob systems. Look at the band and its corresponding frequency range and wavelength:
NFC or near-field communication is a subset of RFID, specifically HF RFID. NFC systems like payments require you to be close (e.g., 10 cm) for them to work.
RFID tags are also classified as follows:
The key fob is a key piece to a car’s keyless entry system. It usually uses 315 MHz low frequency to communicate with the vehicle. When one pushes a button on their key fob remote control, it transmits a signal to the vehicle to unlock the door.
Keyless entry systems vary by model, with the key fob through the distinct code it sends the vehicle serving as a form of identification instantaneously.
A key fob for a car or clicker is one of the most popular. The remote key exists in many iterations and forms, including one with a key inside the fob and a push-button start key fob for a keyless ignition system.
Access key fobs are small devices that let you enter buildings. This is how they work: hold the key fob up close to a reader installed on the electronically powered door to unlock.
Similar to access key fobs are keycards, also credentials for entry to offices and hotels. Tap the card (or in some cases, swipe or insert the card) on the reader. Some access cards double as identification cards with names and photos.
USB flash drives that are set up to secure computer files are also referred to as key fobs. The flash drive and software act as a key to unlock the device and gain access to its contents.
Key fobs, along with key cards, are considered security tokens. These devices utilize RFID, FIDO, USB, Bluetooth, or other technologies to facilitate authorized access or authentication.
A proximity key, or proximity key fob, is primarily used to unlock or lock a vehicle. Even while the fob is inside your pocket or bag, it can communicate with the car’s sensors to allow access as long as it’s within the required proximity. You only need to touch the car’s handle.
Check out these top reasons why key fobs have been widely used and adopted in various settings:
It’s a small device that has a big impact on everyday life. Key fobs have practical uses almost anywhere, including the following:
Yes, key fob and card copying service providers cater to businesses and individuals. You will be asked to show proof that you own the key before any duplication.
The same procedure—showing that you are the owner—also applies to buying replacement car keys and fobs, usually done at dealerships.
Local locksmiths can also offer replacement or duplication services for your keys.
Yes, car key fobs and other keyless entry systems that rely on proximity are vulnerable to relay theft attacks. With an inexpensive relay box, a thief can access your vehicle in under 30 seconds, allowing your car to be stolen right out of your driveway.
The relay attack is among the many methods hackers use to exploit the keyless entry system’s vulnerabilities. Other examples of how they hack into the system are as follows:
Note that the vulnerability of a car to hacking depends on its model and age (if it’s installed with technologies that may have addressed those flaws).
Key fobs are part of a larger security system. They can be deactivated if lost or misplaced, unlike physical keys. This feature makes them more secure, and the additional security is worth the cost.
These convenient devices, however, carry security risks. They are susceptible to hacking and unauthorized key duplication because gaining access means getting high-value items like cars.
Protecting your key fob and keeping your property and the items inside it safe and secure is imperative.
Key fob security refers to processes or products designed to protect fobs and related devices or lower security risks associated with those kinds of systems.
