Keyless entry systems are advanced access control mechanisms that allow users to unlock and enter vehicles or buildings without the use of traditional mechanical keys. Utilising radio frequency identification (RFID), these systems involve a transmitter and a receiver; the user carries the transmitter—commonly in the form of a key fob or a smart card—which, upon approaching the receiver, prompts an exchange of security-coded data, resulting in the unlocking of the door. This technology is often paired with a push-button start system in vehicles, enabling a keyless start function that enhances convenience and security.
The evolution of keyless entry systems integrates various technologies including Bluetooth, biometrics, and near-field communication (NFC), which further secure and simplify the entry processes. In more sophisticated setups, biometric verifications such as fingerprint or iris scans are employed, ensuring a higher level of security by tying access to unique human traits. NFC technology allows for the use of smartphones and other smart devices as transmitters, expanding usability and integration into personal device ecosystems.
The application of keyless entry systems spans across multiple domains from automotive to residential and commercial properties, reflecting a shift towards more secure, technology-driven environments. These systems not only offer enhanced security by employing encryption in the communication between transmitter and receiver but also provide data logging capabilities for entry monitoring, an important feature for security management in sensitive areas. Their adaptability in terms of access methods and the potential for integration with other smart home or smart vehicle systems position keyless entry technologies as a cornerstone of modern access control solutions.
