Door Key Fob

What is a Door Key Fob?

A Door Key Fob is a wireless device that allows users to unlock a door or lock. They are a common replacement for traditional metal keys.

They rely on RFID technology. When a fob is close to the reader device, a copper coil in both devices energizes and transmits a coded signal. The reader device only allows access if the transmission matches what it is programmed to accept.

Easy to Use

Key fob systems are easy to use and convenient for both building staff and tenants. They eliminate the need to keep track of multiple keys or have to worry about losing a key. Fobs are also more secure than traditional metal keys as they can’t be copied as easily and they offer superior tracking capabilities.

Fobs have a microchip inside that transmits a signal when tapped against a reader. The reader then checks with a central system to ensure the fob is authenticated. If it is, the reader will unlock the door for that individual.

These systems can be configured to limit access to specific rooms or doors within a facility, giving employees or contractors only the access they need to do their jobs. Additionally, fobs can be triggered to automatically open a lock when the user is in proximity to it.

Fob systems also require less maintenance than other types of security systems, such as a keypad or biometrics, which can be complicated to install and maintain. However, there are some things you should consider before implementing a key fob system in your commercial building:

More Secure

Key fobs are not only easy to use, but they are also much more secure than traditional key and lock systems. This is because key fobs utilize RFID (Radio Frequency Identification Device) technology, which is efficient, safe and programmable.

When a user approaches a door, he or she simply needs to wave the fob in front of the reader. It then Door Key Fob scans the information contained in the fob’s microchip. If the reader finds a match, it will open the door or lock. If not, the reader will reject the information and refuse to perform the function.

This makes a door entry system more secure than other methods of access control, such as coded options that can be easily shared and used by bad actors. With key fobs, it’s easy to track who is in and out of a building or room, which can reduce internal theft, shrinkage and loss.

It’s also possible to restrict who has access to your building, doors and locks based on specific days of the week or shifts, which is ideal for businesses. Fobs are also more secure than cards, because they cannot be easily copied and hacked by bad actors. They are also less prone to wear and tear, so they will not break or get lost as easily as a traditional card.

Easy to Manage

The key fob system allows for easy management of who has access to your building, and it also creates an audit trail. This means that you can easily keep track of when employees come and go and which doors they use. The system will also notify you if a fob is lost or stolen, meaning that the person who has it won’t be able to enter your property anymore.

Fobs are cheaper and easier to maintain than traditional keys. They’re also much safer, since they can’t be copied in the same way that physical keys can. They can also be deactivated if an employee loses one, allowing you to quickly remove access to your building or office. In addition, they can be linked to other security systems such as CCTV to provide two-layer security measures.

Key fobs are a simple, cost-efficient, and convenient option for business owners, apartment owners, and anyone else who requires access control to their building or area. They work in a similar way to traditional key cards, and rely on short-range communication to unlock doors and other devices.

Incorporating a visitor management component into your key fob system will enhance building security, streamline guest experiences and improve accountability for your staff and guests. By integrating a visitor management system with your key fob system, you can say goodbye to clunky sign-in books and long waiting times for visitors.


When you want to enter a door or access system, simply hold the fob up to it and it will trigger the lock to open. This works because most Key Fobs use RFID (Radio Frequency Identification Technology) to communicate with the system. When a Fob is held up to the reader, the copper coil on both sides energizes and creates a radio wave that reads a microchip inside of the fob. This microchip sends a unique number that identifies the fob and the user. These numbers are matched and approved by the system to grant access. Fobs can also be programmed to have customisable access levels. For example, building managers can have full access, while help desk employees can only access certain areas.

Fobs are more secure than keys because they are incredibly hard to copy. Plus, they have low to no mechanical Door Key Fob wear and can be programmed remotely. Fobs can even be paired with different systems such as CCTV to add an extra layer of security to your workplace by requiring two-layer verification before someone can enter.

Adding a Key Fob system to your commercial building can be a game-changing decision. Assess your building’s specific needs and prioritize the must-have features for enhanced security, user convenience, and seamless integration. By making smart choices, you can ensure a better future for your business.
