Unlock your front door with your phone

nuki’s keyless way of unlocking the door makes it easy to get in the house when you’re laden with shopping by using your phone. You simply walk up to your front door (with your phone in your pocket or handbag) and it will unlock. Brilliant for teens who are in the habit of losing their keys (and strangely, not their phone…).
