Built with a durable aluminum alloy panel, the Tenon T15 is corrosion-resistant and built to last. It installs easily on most standard doors—compatible with 99% of door types—and offers 4-in-1 access via fingerprint, password, key fob, or mechanical key, making it ideal for homes, offices, bedrooms, and more. Powered by 4 AA batteries, it alerts you when power is low and includes a Type-C emergency charging port for backup. The Silent Mode ensures quiet operation at night, while the anti-theft alert triggers a loud siren if any break-in attempt is detected—keeping your space secure around the clock.
