BMW has upgraded its Digital Key function so that it can now be shared across platforms between iPhone and Android devices. 

Keys – which allow a vehicle to be locked, unlocked, and started via smartphone – could previously only be shared via Apple iMessage. 

There is now no specific app or a set method of transmission needed, with keys able to be sent by methods including email, SMS, or any other messaging service.

The new function is available for all new vehicles with BMW Digital Key or BMW Digital Key Plus. Older suitably equipped vehicles will be able to make full use of this feature once their software has been updated to status “22-11” or later via Remote Software Upgrade.
