As one of the pioneers in the use of a smartphone as a digital vehicle key since 2018, BMW is pressing ahead with the development and popularisation of its BMW Digital Key feature, which is now available for iPhone users.
In line with this goal, BMW will introduce the BMW Digital Key Plus, a convenient and secure way of unlocking and starting a vehicle without the need to remove one's iPhone from their bag or pocket. This latest incarnation of the service is based on Ultra-Wideband (UWB) technology, the technology found on the U1 chip of the iPhone. The BMW Digital Key Plus feature will be first launched with the fully electric BMW iX.
The new ultra-wideband technology is characterised by an exceptionally precise localisation for the greatest possible security.
UWB's precision also ensures that relay attacks, where the radio signal is jammed or intercepted, are not possible. Apple and BMW have been working closely with the Car Connectivity Consortium to establish the Digital Key specification 3.0 for UWB, providing a global standard for the automotive industry.
