What is a keyless entry lock?
Keyless entry locks include any type of lock that doesn't require a key to gain entry. This includes magnetic sensors, RFID chips, radio remote controls (like those used for cars) and number pads, though it can also include locks that use thumbprint and retinal scanners, voice recognition and biometric imaging.
These days most of these locks will by necessity contain some sort of electrical component, but some purely mechanical models do exist. Combination locks such as that on a safe are not usually included as the term ‘keyless’ is really only used to refer to lock types that have previously required keys.
How do keyless entry locks work?
Keyless entry locks may work on different systems of recognition – a correct PIN keyed into a number pad for instance, or a successful retinal scan - but the basic premise is the same. Once the correct data has been received, the bolt will either automatically slide back in an electronic model, or will allow release via a thumb button or twist lever in mechanised models.
Most electronic keyless entry locks work using batteries rather than mains power.
Where are keyless entry locks used?
Keyless entry locks are a fairly new phenomenon and until recently, were only used in high tech facilities requiring additional security. Nowadays though, they are being installed in safety-conscious homes across Australia as main entranceway locks. The lack of a physical key in most cases means that once a door is locked, it can’t be picked or otherwise opened except by those with either the right radio, magnetic or combination key, or even the right thumbprint or eyeball.
What types of keyless entry locks exist?
There are a lot of different keyless entry technologies on the market, all of which have their various pros and cons. For the most part, the types used in homes are of the deadbolt variety. It's worth investigating what's involved not just in terms of how easy each available model is to use, but also how it's likely to consume batteries, and how easily you'll be able to get help if you happen to need someone to fix it.
