How Wireless Home Security Locks Work

Basic Components

• Wireless home security locks include a few standard components like an electronic door lock, doorknob, keypad, a wireless bridge and the necessary software. An electronic door lock is similar to a standard deadbolt, except that it uses electronic components to extend and retract the bolt rather than a manual key or knob turn.

Setup

• Electronic locks, doorknobs and keypads should be installed on your front door just like a regular deadbolt. Each particular system includes proprietary equipment, and each has nuances specific to it that require you to strictly adhere to installation instructions. A wireless bridge connects to your modem or router via an Ethernet cord. The bridge should be installed near the electronic lock because the signal between the two often is not that strong. Each system's manual should detail the maximum placement distance for your particular lock. You then install software on your computer to link into the system.

Communicating With a Lock

• The wireless bridge automatically detects the electronic lock and gives commands to the device. Communication between the two devices resembles that of a remote-entry car. The bridge sends low-powered radio frequencies to the electronic lock, triggering the locking or unlocking mechanism. If you press the "unlock" button using the provided key fob, it sends a signal to the wireless bridge, which then sends the proper command to the lock. The software on the computer allows you to set up PIN numbers for the lock's keypad.

Over the Internet

• Many wireless home security locks allow you to access the locks through the Internet or via your mobile phone. Depending on the system, the company will provide a secure website through which you can create an account and register your wireless lock. You can then access this site remotely or from your mobile phone (the company might provide a complete mobile application), to check the door or to lock or unlock it. This comes in handy if you have already driven to work or left for vacation and cannot remember whether you locked up the house before you left. The website and software trigger the bridge, sending the proper command to the electronic lock.

Potential Uses

• Wireless home security locks often tie into a larger home automation system, using the same software and wireless bridge. This means you can add additional locks around your house to remotely monitor and trigger. You can also monitor your lights and other appliances, such as a burglar alarm or a heater, with the proper hardware and connections. Some devices let you create user codes. This alerts the system to send an email or text message when someone uses a particular code. Depending on the brand, a device could let you configure a new key without the aid of a locksmith.
