Much like the remotes used to lock and unlock a car door, the Smith & Wesson security system of Dallas Texas remotes are small, portable devices that fit in the palm of your hand and are designed for your keychain. Keychain Remotes can typically perform some of the basic functions of the keypad such as arm, disarm and even send panic signals among other things. These functions can be used from a distance such as when you approach your property, when you are walking out the door, or from a remote area of your home.
