Import Electronic Digital Keypad Door Lock — Buy in Bulk from Supplier in Taiwan

The electronic digital keypad door lock from Sun Castle Global Precision Technology Co. is a mechanical-electronic hybrid system designed for residential and commercial access control. It operates via a numeric keypad with temporary code functionality and supports backup access via physical card or override key. The lock body is constructed from die-cast zinc alloy with a corrosion-resistant finish, rated for outdoor use in temperatures from -20°C to 60°C.

The locking mechanism uses a motor-driven deadbolt with a 15 mm throw, powered by four AA alkaline batteries with a typical lifespan of 12 months under 10 operations per day. The keypad is IP54-rated for dust and water resistance, with backlit keys for low-light operation. The system includes an anti-tamper alarm that triggers after three consecutive failed attempts and logs up to 100 access events internally. There is no mention of wireless connectivity, remote control, or integration with smart home platforms.

This lock is primarily purchased by property managers, hotel operators, and small office landlords in North America, Europe, and Southeast Asia who require keyless access without network dependency. Units are shipped in bulk packaging with mounting hardware and installation manuals. Trade terms are typically FOB Taichung Port, with lead times of 3 to 5 weeks depending on order size. Buyers should confirm battery type compatibility and emergency override procedures directly with the supplier.
