One of the most recent advancements in automotive key technology is push button ignition and keyless entry. Push-button ignition allows drivers to start their vehicles with the touch of a button, while keyless entry enables them to open and lock their car doors without needing the actual key.

These systems leverage a combination of RFID technology and proximity sensors to detect the presence of the key fob and allow access to the car. They offer greater convenience and ease of use for drivers, as they no longer need to physically handle the key to enter or start their cars.

However, they have some drawbacks, such as the possibility of hacking and theft, as well as the requirement for regular key fob battery changes.

4. Smart keys for cars and proximity sensors

The latest developments in automobile key technology include proximity sensors and smart keys for cars. Electronic and keyless entry advancements are combined with increased security and convenience in smart keys.

Smart keys employ a microchip to interact with the car’s computer system and alow push-button starting. Because of proximity sensors, they may also automatically open the automobile doors when the driver gets close to them, one of the example of this is smart key for BMW.

Additionally, smart keys provide several advantages, including automated climate control settings, memory for position of the seat and mirrors, and even remote engine starting. They also make it unnecessary for the car driver to manage the key physically, lowering the risk of theft and facilitating entry to the vehicle in dimly lit or difficult-to-reach areas.

5. Biometric car keys: Fingerprint recognition and beyond

Biometric car keys take automobile key trend to the next level by using biometric data, such as fingerprint recognition or facial recognition, to authenticate the driver and allow access to the car.

Today, fingerprint recognition is one of the most common form of biometric authentication used in car keys. It enables the car to be unlocked and started only by the driver whose fingerprints have been registered in the car’s computer system.

Needless to say, biometric car keys offer the highest level of security and convenience. They remove the need for physical keys or key fobs, and the risk of them being lost or stolen. They often also come with additional features to provide personalized settings for each driver, such as seat position, climate control, and infotainment preferences.
