It takes less than five seconds for a hacker to compromise a standard keyless vehicle entry system. Bosch’s Perfectly Keyless system revolutionizes keyless entry systems. The technology works with a virtual key stored in the smartphone. Sensors installed in the car recognize the owner’s smartphone as securely as a fingerprint and open the vehicle only for them. Digital key management links the app and the vehicle via the cloud. The new smartphone-based key can be used in cars, entire car-sharing fleets, and commercial vehicles.

With conventional keyless entry systems, the car key still needs to be carried in a jacket or suit pocket, for example. To open the door and start the engine, it communicates with the car using a radio signal in the low frequency (LF) or ultra-high frequency (UHF) range. Instead of transmitting data via low or high frequency radio technology, the Bosch system uses the smartphone as virtual key and Bluetooth as the transmission technology. This means that the car key does not need to be carried in person.

Every smartphone contains tiny microchips to manage communication via Bluetooth, and these play a key role in the Bosch solution. Together with sensors installed in the vehicle and a special control unit, they form a system that opens the door only for the smartphone containing the virtual key that fits in the Perfectly Keyless system’s digital lock. The system blocks signals from other smartphones or from electronic devices that manipulate the radio transmission. In this way, Perfectly Keyless protects against unauthorized access.
