Isn't it about time that your house caught up to your car in terms of remote access options? The Locca Access remote key entry allows you to open your house's front door from up to 50 meters away—super convenient for those times when you are laden with shopping bags, when it's dark, when the weather is bad or when you're just too damn lazy to use your complicated keys.
You can even let guests into your house remotely from up to 20 interior meters away, so there's really no need to put on clothes or get up from that sofa to answer the door. The Locca Access works in conjunction with your existing locks, contains a 48 hours battery in case of power failure and comes with a manual key override, so it seems like they've got all your bases covered. Retails for £150.
