Digital Car Keys: Everything You Need to Know

What Is a Digital Car Key?

A digital car key is a virtual version of your traditional car key, stored securely on your smartphone or wearable device. Utilising technologies like Bluetooth Low Energy (BLE), Near Field Communication (NFC), or Ultra-Wideband (UWB), it allows you to lock, unlock, and even start your car without a physical key. Think of it as turning your phone into a smart key, like how digital wallets have replaced physical wallets.

 

How Do Digital Car Keys Work?

Your device and the car communicate securely for digital car keys to work. Here's a simple breakdown.

 

• Authentication: Your smartphone or wearable device stores an encrypted digital key that is connected to your car.

• Communication: When you get close to the vehicle, the gadget uses BLE, NFC, or UWB to authenticate access.

• Access control: After successfully authenticating, you can start the engine, unlock doors, and even remotely grant others access.

 

Manufacturers frequently incorporate these functions into their proprietary applications to provide seamless user experiences.

 

What’s The Difference Between a Key Fob and A Digital Key?

Although they both provide access to your car, there are some key distinctions.

 

• Key fob: A physical gadget that connects with the car via radio frequencies. It requires batteries that need replacement and is subject to damage or loss.

• Digital key: An app-based, intangible solution that runs on your wearable or smartphone. Its improved features include real-time alerts, remote access sharing, and connection with other digital services.

 

Essentially, a digital key uses already-existing personal devices to provide additional convenience and utility, whereas a key fob is a specialised device.

 

What Are the Benefits of the Digital Key?

There are several benefits to adopting a digital key:

 

• Improved convenience: Your smartphone is the access point, eliminating the need to dig around for keys.

• Remote access: Perfect for family members or valet services, this feature allows you to grant or cancel access to others without requiring actual handovers.

• Integrated security: Biometric authentication, such as fingerprint or face recognition, and advanced encryption provide additional levels of security.

• Smooth integration: For a comprehensive driving experience, integrate with additional digital services like navigation applications or car diagnostics.

• Eco-friendly: Reducing the need for physical keys helps to cut down on waste from plastic and electronics.

 

Do Digital Keys Affect Your Insurance Premium?

• A digital car key enhances vehicle security but does not guarantee insurance discounts. 

• In India, insurers may provide a 2.5% discount (up to ₹500) for vehicles with ARAI-approved anti-theft devices (e.g., immobilisers, alarms, GPS trackers).

• Digital key systems are currently not recognised by ARAI for discounts, so an approved device is required to qualify. 

• Some insurers may consider digital keys in assessing theft risk, but this could also increase repair costs.

• Consider getting a Key Replacement Add-on in your Car Insurance policy. Although it is an additional charge, it can help cover the cost of reprogramming or replacing lost or damaged digital keys, which can be expensive.

• To improve security and possibly qualify for discounts, pair a digital key with an ARAI-certified anti-theft device.
