F17: The Smart Lock Built for Russian Winters (-25°C)

A regular smart lock in Russian winter is a lottery: the reader freezes, the battery dies, the plastic panel cracks. F17 was built specifically for the cold climate of Russia and Central Asia.

What sets F17 apart

• Cold resistance to -25°C — electronics and mechanics rated for harsh winters
• Glass panel — doesn't crack in frost, unlike plastic
• Optional fingerprint module — wearing gloves? Enter a PIN
• TTLock ecosystem — codes, e-keys, logs, remote management

Ideal for

• Entrance doors of apartments and houses
• Offices and warehouses with unheated vestibules
• Short-term rentals — code check-in without meetings

Why it matters for importers

Most Chinese smart locks are rated for -10°C...-20°C. In Novosibirsk or Astana winters, that means returns and reputation damage. F17 closes the gap.
