Electronic Door Hardware For Residences

Electronic locking systems have been popular for many years in commercial applications. Electronics have also been applied to automotive security beginning with a VATS system on the 1986 Chevrolet Corvette. Electronic door hardware for residences is probably the most significant area in terms of possible sales volume but this area has lagged behind in available products.

Master Lock now has a new electronic security product for the residential market. Features include a ‘weather tough’ keypad ready for harsh outdoor use, key cylinder backup with BumpStop technology and the NightWatch locking system to lock out all keys and codes. After the door is locked, owners can press a button on the bottom of the inner escutcheon and simultaneously pull outward on the thumb turn. This NightWatch system makes the thumb turn rigid and prevents anyone from unlocking the door from the outside.

Although the primary feature is keyless entry, a variety of cylinder keyways are available including Kwikset, Schlage C, Schlage E, Yale, Segal, Arrow plus the Master recodeable key system.

The keypad has six buttons labelled 1-2, 3-4, 5-6, 7-8, 9-0 and ‘enter’. Code numbers of 4 to 10 digits can be used. The Master Lock Keypad Deadbolt can hold up to 20 individual user codes. Locks are factory-set with two user codes. To operate the lock, press any button to activate the keypad. The keypad will illuminate in blue, indicating it is ready to operate. Next, enter a valid user code and then press the ‘enter’ button. The keypad will illuminate in green when a valid code is entered. A dial surrounding the lock cylinder is normally freewheeling. When the keypad is illuminated in green, the dial clutch engages and the dial can be turned to unlock the lock.

When leaving home, the inside thumb turn must be turned to unlock the door. Next, the ‘exit’ button located on the inside escutcheon plate must be pressed. This activates the clutch mechanism and also sets the keypad to flashing green. After closing the door from the outside, the homeowner has 15 seconds to turn the dial and lock the deadbolt before the dial clutch disengages and the keypad is no longer illuminated.

While at home, the owner can choose to set the NightWatch feature. A release button is located on the bottom of the inner escutcheon plate. With the lock in a locked position, the owner can push up on the release button and simultaneously pull outward on the thumb turn. This sets the thumb turn into a rigid position and prevents anyone from entering either with the proper key or a valid user code. The NightWatch feature can be released at any time by pushing inward on the thumb turn.

A factory-set administrative code must be used for all programming functions. Individual factory-set administrative and user code numbers are printed in the front of each user guide book. The upper portion of the inside escutcheon must be unsnapped and removed when reprogramming the Keypad Deadbolt.
