The Future of Car Keys: Are Physical Keys Becoming Obsolete?

July 2, 2025

Over the last several decades, we’ve seen car keys evolve from mechanical devices into leading-edge digital technology solutions. With the rapid pace of advancement, it’s easy to wonder are physical car keys becoming obsolete?. These new systems feature digital keys, integration with your smartphone, and biometric-based systems. Digital car keys, once considered futuristic, are the new reality and technology for accessing your car.

Car keys were first introduced around 1910. They were designed to enhance security, allowing a driver to unlock the engine of the vehicle but they were not used to start the car. Later, in 1949, car keys changed so they could unlock and directly start the engine. Fast forward to today, we once again are seeing car keys undergo a major transformation. The traditional metal key, long a symbol of vehicle ownership, may soon become a relic of times gone by.

Digital Car Keys and Keyless Entry

With digital keys for the car, a driver can lock, unlock, start or share their car without needing a mechanical key. These keys typically use Bluetooth Low Energy (BLE), ultra-wideband (UWB), or NFC technology to communicate with the car. These may also be combined with biometric features that add to the level of security.

Major technology companies are eagerly partnering with manufacturers to help make smartphone-based digital entry systems the norm. In our hyper-connected digital world, consumers have increasingly come to expect integrated experiences. Digital keys let car owners customise their driving profiles. They can also share access to the vehicle remotely with friends or family and track the vehicle’s location in real time.

Integration with Your Smartphone

Integrating smartphones into the access system for your vehicle has opened up ways that a driver can interact with the car. Mobile apps make it easy to lock or unlock your car’s doors or start up the engine. Some also allow you to remotely adjust the vehicle’s climate controls. These new systems allow you to easily manage your vehicle from your smartphone, without any need for the key fob you used previously.

Leading manufacturers have developed their own proprietary mobile apps to manage and facilitate these advanced features, and to create a seamless, custom user experience. They have also included enhanced security measures like multi-factor authentication and encryption to help safeguard these new access systems.

Biometric Security and Vehicle Access

To further protect digital access systems, biomet

ric security and authentication is becoming critical. By utilising distinct physical aspects like facial recognition or fingerprints, these systems can identify and then authorise drivers of the vehicle. Since it is difficult to clone or steal biometric data, this technology offers a key level of security that helps protect both driver and car.

Some automotive manufacturers have equipped their cars and utes with fingerprint scanners that can be used to keylessly unlock or start the vehicle. As these technologies improve, expect to see biometric authentication become standard on new cars.

So, Are Physical Car Keys Going Away?

Over the years, car keys have evolved to go from mere mechanical devices to smart, seamless digital solutions. Integrating digital keys with smartphones, and protecting them with biometric authentication, has led to a dramatic revolution in how we secure and interact with our vehicles.
