Kwikset Kevo combines a traditional key lock with keyless entry; due for launch this summer
Kwikset has introduced a new lock that uses your iPhone as an alternative key mechanism.
The US lock maker unveiled Kevo, which has both a standard key tumbler as well as the new electronic mechanism.
Keyless entry technology has been around for a while now. Moving it to a device like the iPhone was a natural progression.
However, the new lock has some other tricks up its sleeve.
It is possible to send a key to someone else's iPhone 4s or 5. This means that in emergencies, someone like a relative or trusted friend could access your house without the need for an expensive locksmith call out.
The temporary keys can be set to work for a limited amount of time. For example, you could give your friend a temporary key that works for two weeks so they can feed a pet while you're away on holiday.
The technology is being positioned as more secure than a traditional key that can be lost.
According to Kwikset, the Kevo lock works for about a year on a set of two AA batteries.
It is set to be released in the US this summer. There is no word on whether it will see a UK release.
We've contacted Kwikset to find out though.
