American Standard Mortise Lock Case for Grip Handle Door Lock

Because of the global first-creative revolutionary design and simple structure, our lock case contains only about 60 pieces components, while other American style door locks cases contain at least 90 pieces components. To achieve the same function, less parts means more simple, stable and effective, trouble free.

Style, security, and convenience are all factors you’ll need to consider when selecting a new lock for your entry, along with your comfort level with the technology needed to implement a smart keyless lock into your home system. Each style presents different benefits and requires different precautions, so you’ll need to consider your own security needs and your lifestyle when deciding which type is best for your home.

A home security system provides an extra layer of protection from intruders. Don’t rely on a door lock alone—Fuyu lock can help. With a comprehensive whole-house solution, you can be prepared for the unexpected.

Traditional key locks are most commonly used, but keyless smart locks are gaining popularity. 

Key locks are the standard in most homes. Available in many styles to fit the design of the door, cost to rekey locks can fit into handsets or latches and be added on as deadbolts. Traditional key locks offer tremendous security, many design options, and flexibility; owners can leave a spare key with a trusted relative or friend, tuck a key into a responsible teen’s backpack, or lend one to a neighbor to let a repairman in, all while knowing that when the keys are returned, the home is secure. The vast majority of households trust traditional key locks for these reasons—plus these locks require no wiring, no Bluetooth, and no internet connection, and they are impossible to hack without physically tampering with the lock. For these reasons, key locks provide a sense of solid security for those who aren’t comfortable enough with technology to entrust their home to it.

Keyless smart locks come in several configurations; some are simply a keypad onto which users type a pin number, but most contemporary versions work via Bluetooth or Wi-Fi and unlock using an app, a paired key fob, or sometimes even a fingerprint. The app or fob sends a message to the lockset on the door and automatically unlocks it, saving you the trouble of fumbling with keys at the door and making your entry hands-free. In addition, many of these locks allow you to unlock the door from great distances via an app; a parent can open a door while they’re at work for a child arriving home from school or even for a repair professional who has arrived at the home. The convenience and easy integration into other smart-home products has spurred a rise in the popularity of smart locks over the last few years, which has increased as more styles and smaller devices have become available. One drawback is that keyless locksets are dependent on power and Wi-Fi: While most come with a battery backup in case of a power outage, they may not function properly if the router has lost power as well.
