The Jacchozhi Warning: Why You Cannot Just "Install" This Smart Lock

The Jacchozhi 3D Face Recognition Smart Door Lock (ASIN B0DHCPRFHW) is not a simple upgrade; it is a structural renovation. While the marketing materials highlight its futuristic biometric capabilities—scanning faces in 0.3 seconds and detecting palms—the most critical specification is hidden in the fine print of the mechanical engineering: Lock Type: Mortise Lock.

For the average American homeowner looking to replace a standard deadbolt with a screwdriver on a Saturday afternoon, this distinction is the difference between a 15-minute project and a full day of carpentry (or a $300 locksmith bill).

The Anatomy of an Invasion: Mortise vs. Cylindrical

Most residential doors in the United States come pre-bored for cylindrical locks. These consist of two circular holes: a 2-1/8” hole on the face of the door and a 1” hole on the edge for the latch.

The Jacchozhi system, however, utilizes a 6068 Mortise Lock Body. As clearly visible in the exploded technical diagrams, this is not a simple latch; it is a massive, rectangular steel gearbox roughly 240mm (9.4 inches) tall and 100mm (4 inches) deep.

The Physical Conflict

To install this device, you cannot simply slide it into existing holes. You must carve out—or “mortise”—a large rectangular pocket inside the solid core of your door.
1. The Cavity: If your door is hollow-core, this installation is structurally impossible. The lock requires a solid wood or metal door to anchor its heavy chassis.
2. The Strike Plate: The receiving end on your door frame is equally complex. Unlike a single hole for a deadbolt, the Jacchozhi features a multi-point locking system with varying bolt positions. As one verified reviewer noted, “the unusual arrangement of dead bolts… need to be drilled out of the jamb.” This often requires cutting into the structural stud of the house frame.

Why Choose the Hard Path?

If the installation is such a formidable barrier, why does this product exist? The answer lies in security density.

A standard deadbolt relies on a single metal rod extending into the frame. If a burglar kicks the door hard enough, the wood frame around that single point often splinters and fails. The Jacchozhi’s mortise body distributes the force across a much larger vertical area. It typically engages multiple bolts simultaneously, transforming the door from a barrier into a barricade.

Furthermore, the “anti-prying safety lock” feature is integrated directly into this chassis. Sensors within the mortise body detect if the faceplate is being forcefully separated from the door. Because the lock body is deeply embedded inside the door rather than just clamped onto it, it is exponentially more difficult to attack with a crowbar.

The Verdict: Contractor Required

This lock belongs to a category of “prosumer” hardware that bridges the gap between residential smart locks and commercial access control.

• Do NOT buy this if you rent your home, have a hollow-core door, or expect a “plug-and-play” replacement for your Schlage or Kwikset deadbolt.
• DO consider this if you are installing a custom front door from scratch or are willing to hire a professional carpenter.

The Jacchozhi 3D Face Recognition Smart Door Lock offers a level of physical security that standard US smart locks cannot match, but it demands a blood sacrifice in the form of sawdust and drilling. It is not just a lock; it is a commitment.
