The Wireless Door Key
You have keyless locks for your car, and a keyless garage door opener, why not have a keyless house?
The Locca Access is a wireless door key is capable of unlocking your door, but don’t worry if something does wrong (or you lose the receiver, or forget to charge it) you can still use a traditional key (that is probably hidden under the flowerpot by the door) to get in. The Locca kit comes with a rechargeable battery that can last up to 48 hours, and is available for $290.

What’s the point if it’s larger than a bunch of keys and has to be recharged overy 48 hours?
I would muck rather some kind of device like at the office here where a Credit Card sized key (actually a card) is in my wallet and when passed over a sensor opens a door.
Much, Much better
either what you said or why not just use a number pad on your door???
$290 and I have to recharge it every other day?
Or I could just use my much-smaller regular key for free.
Uh oh, someone just hacked into my house and stole everthing
“Uh oh, someone just hacked into my house and stole everthing”
Yeah, it’s called lock picking. This isn’t any less safe than a regular lock.
And I agree, a fob that must be recharged every couple of days is lame. Why not just get an RFID chip in your hand and have a reader in the doorknob? That would be awesome. -)
It doesn’t have to be recharged after 48 hours. They say the battery backup will last 48 hours if the power goes out.
