No Drilling Smart Door Lock Guide: Embedded 3D Face Lock

No Drilling Smart Door Lock: Upgrade Your Door Without Modification

Want to upgrade your old door to a smart lock but don’t want to drill holes or damage it? A no-drilling embedded smart lock is the answer. The SK-Q2 Tuya embedded smart lock installs directly onto your existing door — no drilling, no modification, no damage.

Why Choose a No-Drilling Embedded Smart Lock?

Traditional smart locks require drilling holes into your door and replacing the lock body — a messy, permanent modification that can damage old wooden doors and void warranties. No-drilling embedded locks mount directly onto the existing door surface, so you can upgrade in minutes and remove it without a trace.

3D Face Recognition for the Whole Family

The SK-Q2 uses true 3D face recognition that works in side face, occlusion, blur, dim light and backlight — no height restrictions. It stores up to 100 faces and detects in milliseconds. Walk up to the door and it opens automatically.

Palm Vein Recognition: The Most Secure Biometric

Wave your hand near the door and the near-infrared light scans the deep vein information in your palm. This internal biometric cannot be photographed, copied or spoofed — making it the most secure unlock method available. It works even if your palm is dirty or wet.

Built-in Camera and Video Intercom

When someone rings the doorbell, the SK-Q2 auto-captures and pushes a live video call to your phone. You can see, talk and remotely unlock — even when you are not home. Perfect for deliveries, food and unexpected visitors.
