Material analysis of the TEEHO Keyless Smart Door Lock reveals a zinc alloy construction with an ANSI Grade 3 residential security rating. Technical specifications categorize this unit as an air-gapped digital lock, as it lacks native Wi-Fi, Z-Wave, or Zigbee networking capabilities. The mechanical drive consists of a solenoid-driven clutch mechanism and a high-torque motor powered by four AA alkaline cells. Standardized testing suggests an operational lifespan of approximately six months per battery cycle.
Physical security features include anti-peep code masking and a physical key override, which is essential given the lack of remote low-battery alerts. The internal chassis is comprised of high-density polymers and zinc components. Because the device operates strictly as a local keypad/RF unit, it eliminates risks associated with remote network intrusion but lacks the capability for remote log history or guest access management.

Schematic analysis identifies the chassis as a Tuya-based ODM white-label, sharing internal layouts with several other budget-tier brands. This design is optimized for low-traffic residential applications rather than high-security environments.
- Access protocols: Local 4-10 digit keypad and physical override.
- Locking modes: Manual one-touch and auto-lock.
- Security tier: ANSI Grade 3.
The Kanfox KS2 Smart Lock offers a similar form factor but adds biometric capacitive scanning for users seeking faster entry without manual codes.
This unit is a standalone entry in the keyless smart locks directory, specializing in offline digital access.
