An electric key, also known as a key fob, is a small, portable device that allows users to access buildings, vehicles, and other electronic lock systems. These keys are often used for keyless entry in automobiles, but they can also be used for a variety of other applications, such as opening specific doors or starting engines. They are highly convenient, especially for individuals with disabilities, as they eliminate the need for turning a physical key.

What You'll Learn
Key fobs
A "key fob", also known as a remote keyless entry system, is a small, hand-held electronic device used to control an electronic lock system, such as a vehicle. The word "fob" likely comes from the German "fuppe", meaning "pocket". Before the advent of electronic key fobs, the term referred to decorative keychains, often featuring a small trinket, a logo, or a photograph.
RFID key fobs are highly versatile and can be programmed to transmit a number of different commands. These often include functions such as opening a specific door or starting an engine. Most automotive key fob units have multiple functions assigned to different buttons. Some key fobs are simply badges that need to be passed in front of an electronic lock to open it, while others have buttons that transmit specific RFID signals to perform different functions, such as locking or unlocking a vehicle.

Electric key cards
An electronic key can refer to several items, including key cards, key fobs, and tokens. This response will focus on electronic key cards.
Electronic key cards, also known as keycards or key card systems, are used to gain access to restricted areas. They are commonly used in hotels, where they work with the most common brands using LOCO 300oe (Low Coercivity) lock types. These lock types are very common in lodging settings. The key card is inserted into a keycard reader installed on the door, which then communicates with the door lock. If the reader recognizes the unique code on the card, it grants access. Otherwise, access is denied.
Key cards can also be used to control electricity consumption in rooms. For example, when a guest inserts their key card into an energy-efficiency device, the electricity is switched on. When the guest leaves the room and removes the card, the electricity is cut off. This helps to reduce energy consumption and improve energy savings.
Key cards can be encoded in various ways, including magnetic stripes and chips. Newer models use radio-frequency identification (RFID) or "smart cards," which contain an embedded microcontroller to handle security. The frequency of the RFID signal determines how far it can travel and how much data can be transmitted. Low-frequency signals travel farther, while high-frequency signals transmit more data.
In addition to access control and energy management, key cards can also be used for payment and other applications. They offer a convenient and secure way to restrict access to specific areas or functions.

Prepayment meters
If you encounter an issue with your prepayment meter, such as a failed transaction or a dirty/damaged key, there are a few troubleshooting steps you can take. Firstly, check your receipt after topping up at a Post Office or PayPoint/Payzone location. If the transaction was unsuccessful, you will need to try again. Additionally, if your key or card is not working, try removing it from the meter, cleaning it with a dry cloth or toothbrush, and then reinserting it.
In the event that your electric key or gas card is lost, damaged, or not working due to an error code, you can obtain a replacement. Contact your energy supplier first to obtain a reference number, and then take that number to a local PayPoint or Payzone location to get a new key or card.
It is important to remember that if you use the emergency credit on your prepayment meter, you will need to purchase enough credit to cover the emergency usage the next time you top up. Your key or card will not function until you have repaid what you owe.

Remote keyless entry
The RKS system largely superseded keyless entry, which bound locking and unlocking functions to vehicle-mounted keypads. An RKS performs the functions of a standard car key without physical contact. When within a few yards of the car, pressing a button on the remote can lock or unlock the doors and may perform other functions.
The RKS system contains a short-range radio transmitter, usually within 5-20 meters, and sends a coded signal to a receiver unit in the car, which locks or unlocks the door. Most RKS systems operate at a frequency of 315 MHz for North American cars and 433.92 MHz for European, Japanese, and Asian cars. Modern systems implement encryption and rotating entry codes to prevent car thieves from intercepting signals.
The RKS system can include both remote keyless entry (RKE), which unlocks the doors, and remote keyless ignition (RKI), which starts the engine. Some remote keyless fobs also feature a panic button that activates the car alarm. Remote keyless entry systems are also used in buildings, providing access to certain areas.

Electronic lock systems
One of the most significant advantages of electronic lock systems is the ability to control access. With electronic locks, you can easily change and reprogram access codes or fingerprints to accommodate new staff or family members, or revoke access for former employees or tenants. This feature also eliminates the need to collect keys or change locks when a key is lost or stolen, saving time and resources.
Another benefit of electronic lock systems is increased convenience. Keyless entry options, such as key fobs, RFID badges, or mobile apps, make it faster and easier to unlock doors, especially for individuals with disabilities who may find it challenging to turn a physical key. These keyless entry methods also offer portability and can consolidate multiple functions into a small device.
When considering an electronic lock system, it's important to choose a system that accommodates your specific needs. Most smart locks are designed to work with standard pre-drilled holes, making installation straightforward. Additionally, some models attach to the inside of your door, utilising your existing keyed cylinder and deadbolt hardware, minimising installation requirements.
In conclusion, electronic lock systems provide a range of benefits, including controlled access, enhanced security, and increased convenience. With the ability to easily manage access codes, monitor entries, and enjoy keyless entry, electronic locks offer a secure and user-friendly alternative to traditional locks.
