Key fobs also work well in a business environment. One reason for this is because of the additional security they provide. Fobs can be immediately blocked if they have been lost or stolen. They can also be blocked when an employee is let go or a service contract is terminated. Some businesses regularly change the access code for restricted areas and reprogram the fobs accordingly. Additionally, it is possible to integrate fobs into a commercial security system.
Among other benefits, this provides a way to track all employee and visitor movements. Although key fobs have many advantages over traditional keys, one disadvantage is that they may be difficult to program. First of all, you will need to purchase an RFID writer and at least one blank fob. Access control systems with proximity readers automatically make a full record of who enters the building and the time of entry. This valuable information is helpful in tracking visitor data, employee attendance, the movement of staff members and the presence of people in case of an emergency.
Key fobs and access cards are popular because they are very customizable. For example, they can be used at the company vending machine or copy machine, gym lockers, hotel supply closets, pharmaceutical stock, and medical equipment rooms. Key fobs and access cards eliminate the need for several keys granting employees access to the areas needed for their work without needing to keep track of multiple keys.
They offer extremely customizable, secure access management. By programming the system, you can easily allow access to particular people or restrict entry during certain time periods. Proximity credentials are also relatively inexpensive and easy to replace if they are lost, stolen, or worn out.
The access system will need to be reprogrammed to block the old fob and grant access to the new one with a new key ID. For most businesses and public buildings, the extra security of the facility, sensitive information, valuable products, and equipment is more than enough to outweigh the cost of up-front investment.
With proximity cards and key fobs, you can avoid the expense of prekeying the property and inconvenience of reissuing new keys to everyone each time one is lost. To open a door using a key fob, you simply need to hold or wave your fob in front of the reader.
Each key fob contains a microchip with a unique frequency that communicates with the reader and indicates that the door should be opened.
Fobs can be programmed to allow levels of access for different uses. For example, you could program your building manager's fob to access all doors in a facility , while a receptionist's fob may only allow access to a few areas. Key takeaway: Key fobs use RFID, or radio waves, to pass information from the fob to an electronic reader and unlock a door without physical contact between the devices. Key fobs are being widely adopted for their ease of use and management.
They eliminate the process of wiggling a metal key around in a lock — all you have to do is hold or wave the fob over the reader. Proximity keys are another great option for easy entry, because you don't even have to take them out of your pocket or purse for them to detect the lock. Key fobs provide the same function as traditional keys but offer additional convenience and security.
If a fob is lost or you wish to deny entry to someone say, a former employee or tenant , you can easily cancel access on that particular fob.

For example, you can allow access to a warehouse only to the necessary employees during their designated work times.
Fobs also enable you to keep records of entries and exits so that you can track attendance, visitors or staff mobility. Key takeaway: Key fobs allow you to limit access to certain areas of your facilities. You can authorize certain employees or other people to enter only the areas necessary to their roles during their designated shifts.
Key fobs and proximity keys are often used for cars with keyless entry, apartment or condominium buildings, parking garages, college campuses, gym facilities, office spaces, and buildings with restricted areas, such as rooms or warehouses that store valuable inventory. Yes, you can make a copy of a key fob. However, it requires some technical knowledge and an RFID reader, which you can buy online and allows you to read and write kHz key fobs, which are the most common type for apartment and office buildings.
If you don't want to do it yourself, there are several key-fob-copying services available that will clone your fob for you. Key fob copying is not a cause for concern; it's equivalent to taking your metal key to the hardware store to make a copy.
The copy is identical to your original fob, meaning it's subject to the same allowances and restrictions. Key takeaway: You can copy key fobs, but it's a somewhat complicated process involving an RFID reader.
Both the transmitter and receiver know the code numbers as they change because they are programmed with the same code generating algorithm. So, both the car and fob know what code number will be next due to sharing an algorithm.
The mathematics of the quasi-randomly generated codes is that it is about a one-in-a-billion chance that a car would mistakenly unlock because of a duplicate code transmission from a wrong fob. Now the car receiver and fob transmitter are no longer in sync as the fob will move one code number ahead of the car receiver.
This problem is solved by the receiver scanning the upcoming codes every-time it receives a signal to see if any of those codes match. If so, it accepts the code and resets the starting point.
So, you can press your key fob up to times out of range of your car without messing up the encryption system. However if you or your toddler or drunk spouse press it times you have an issue and will need to figure out how to reset it. Many times, I have in inadvertently left the fob inside the car and touched the handle to lock the car.
