The KS300 is our slimline smart lock — engineered for the narrow stiles found on french doors, aluminium joinery and sliding doors. A 303 × 42 mm panel squeezes into spaces no standard smart lock can reach, with the full TTLock feature set behind it.

Managed through the TTLock app, the KS300 brings keypad, RFID card, Bluetooth app, proximity unlock and a mechanical key backup to doors that previously couldn't fit a smart entry system. The slim profile pairs cleanly with both aluminium and timber construction.

Built for NZ conditions. IP65 dust- and water-resistant for full exterior exposure on covered or uncovered entries. Backed by a 2-year manufacturer warranty.*

Key features
  • Slimline profile — fits narrow stile doors that standard smart locks can't
  • Five ways to unlock: Bluetooth app, RFID card, proximity dot, PIN code or physical key
  • TTLock app (iOS & Android) — passcode sharing, eKeys, access logs, remote management
  • Hidden mechanical key cylinder for emergency override
  • Material: Aluminium alloy (Black) or 304 stainless steel (Brushed Nickel)
  • Finish: Matte black or brushed nickel
  • Panel size: 303 × 42 mm
  • IP65 dust- and water-resistant — built for NZ conditions
  • Powered by 4 × AAA batteries (8,000–10,000 unlocks / 8–12 months)
  • Bluetooth 5.0; Wi-Fi gateway compatible
  • 2-year manufacturer warranty*

Choose your backset:

The KS300 supports a wider range of mortice backsets than any other lock in the range — 30 mm to 60 mm for standard hinged doors, plus dedicated sliding-door options at 28, 35 and 45 mm. Select "Handle Only" if you already have a compatible mortice in place.
