Biometric locks are locks that don't need keys. Instead, the key is a person - either your fingerprint or your eye. And before you get carried away thinking about how people trying to get into your home will just cut off your finger or extract your eyeball - remember the convenience and safety factors.
Where the lock is biometric is really more about the opening mechanism. You can still choose between different types of locks to go with your biometric reader - from deadbolts to cylinder locks to magnetic locks.
And what could be more romantic? Giving your partner a key to your place has long been a symbolic step in a relationship but imagine stealing his or her finger print in their sleep and them magically opening the door? Okay, so maybe not. But biometric locks are probably the way of the future and are being used more and more often in small businesses and domestic homes.
The installation of a biometric lock is usually simple and requires few wires, but the trickiest part is getting power to the fingerprint reader. As there is wiring involved, the installation also requires a licensed electrician, however most locksmiths who offer biometric locks will work with an electrician to do this.
