The Prezlock Smart Padlock combines a 508 DPI capacitive fingerprint sensor with a physical key backup. Material analysis confirms a zinc alloy chassis and a 3.7V 160mAh Li-Po battery. The mechanical actuator is a low-voltage DC motor. Technical documentation reveals that while the biometric response is fast, the mechanical linkage is a common failure point that may result in the locking pin failing to retract.
Aggregated reports indicate that the IP65 rating is often compromised by moderate rain, leading to circuit shorts. The physical key backup serves as a mandatory fail-safe for the common electronic and motor failures noted in this hardware class. High self-discharge rates in the lithium battery can occur in cold climates, necessitating regular charging via the micro-USB port.
The eufy C33 is an alternative for users who require a much more robust motor assembly and superior environmental sealing for permanent door installations.
This device is situated within the biometric padlock with mechanical override classification.
