We can't count how many times we've wished for something like this. If car makers have long known the convenience of an electronic remote key, why haven't homebuilders figured out a similar concept for the front door?
Locca Access is one such remote system made by a U.K. company that can unlock your door from up to 50 meters away. (That's about 164 feet to us Yanks.) It can store up to 19 keys and promises to work even in a power outage, running on its own battery for 48 hours.
The kicker? Red Ferret says it can work from inside the house as well, meaning that you can let in visitors without ever leaving the couch. Sweet.
