Car with no keys - Will phone apps take over?
You've heard of the pub with no beer - now we have the car with no keys.
Instead of a physical key which you would either have in your pocket or stick in the ignition, you'll get an app on your mobile phone that will do it all digitally.
And Volvo is planning to be the world's first carmaker to have the system up and running - they say by next year.
Basically, owners will be able to get an application for their mobile phone to replace the physical key with a digital version.
The Bluetooth-enabled technology will, Volvo say, give customers more flexibility.
They say it will make it much easier to use and share cars.
The app key will let you do everything - locking or unlocking doors or boot and starting the engine - that a current one does.
And it will be possible to have more than one 'key' on your app.
That, say Volvo, should make it possible to, among other things, book a rental car anywhere in the world and have the key delivered to your phone.
