Lock Key-less Entry Can Enhance the Protection of Your Home

In every type of door lock, a bolt or latch is moved to cross the opening between the door frame and the side of a door, and this acts to prevent access to the room or space served by that door. In normal locks, this movement of the latch is enabled by keys, that must be carried by the person wanting to lock the door or requiring to open it. A lock key-less entry device allows these latches or bolts to be actuated electronically by a motor that is buried in the door or frame.

To activate the lock it is necessary to key in codes on keypads that are near the doors, or even allow this activation through handheld devices or even messages sent over the internet, or through radio waves. Keyless remotes that are often used for cars have a short-range radio transmitter that needs to be within the range of the lock that needs to be activated. The push of a button will send a coded radio signal to a receiver unit that is in the car and this, in turn, allows the lock to be opened or locked. The earlier keyless system used infrared instead of the radio.

The radiofrequency in car locks that use keyless entry has a distinct code that ensures its digital identity and is put in place by automobile manufacturers though proprietary technical processes that ensure that every lock has its uniqueness. Other keyless locks trigger the transponder in the car when the key is in close proximity, and this does not require the pressing of any button or sending a code.

A lock key-less entry system can also be used for residences, offices, and businesses. Many of these systems use the internet to send a code that the user can activate through a smartphone or other devices. These smart locks or keyless door locks do not require any key. You can even have such key-less entry that is activated by bio-metric means through the use of facial, iris or thumbprint activation. These locks require careful programming that must take security into account.

The use of keyless locks reduces the need for carrying keys, which can get misplaced. Present-day keyless locks even allow you to create separate codes for guests, sitters, caregivers or others who need temporary access to your home or place of business. You can even put up these locks on homes or rooms that you lease out, and can just change the code one the renter leaves. Some of these locks can store as many as 30 different user codes that can be used at the same time, so you can even have every member of your family with his or her code to lock and unlock the door.

Most keyless locks require batteries and the best ones have a backup battery that allows you to change batteries in time before you get locked out, due to low power. Key-less locks have gone a long way in ensuring the safety and protection of premises.
