N2 (N2F) Smart Handle Door Lock
Ultra-thin zinc alloy handle lock with six-month battery life
The N2 and N2F are ultra-thin all-zinc-alloy handle locks with an intentionally small lock core, so the door needs as little machining as possible during installation. They run five entry methods on four AA alkaline batteries for more than six months, and carry a free handle that keeps external force away from the internal structure.
- Ultra-thin lock core minimises the hole cut into the door
- More than 6 months and 180,000 operations on 4 AA alkaline batteries, with a USB port for emergency charging
- FPC semiconductor sensor with 360-degree, 550 DPI fingerprint recognition
- Free handle prevents external stress from reaching the internal structure
- Working temperature -30 C to +65 C, on wood, steel, stainless steel and aluminium doors
Suitable for: Hotel and apartment operators, and buyers specifying access hardware for mixed door materials.

Quality control
Every circuit board is tested to confirm its lifespan before assembly. Units pass waterproof, mildew-proof, high and low temperature, vibration and ageing tests so the lock holds up in harsh environments.
Customization
Body material can be specified in zinc alloy, stainless steel or copper. Ostuyad runs its own R&D team and production lines, and customers are welcome to come and inspect.
How it compares
Against the T1 and T2 hotel locks, the N2 leads on installation: the ultra-thin core cuts less of the door away. Choose the T2 when a SUS304 mortise and hotel card hierarchy matter more than a minimal cut-out.
Installation and use
Authorise an administrator in the TTLock app first, then add users and review unlock history from the app. Change batteries when the lack-of-voltage indication appears rather than waiting for a failure; the USB port covers the gap if it is missed.
FAQ
N2 / N2F questions
How long do the batteries last?
More than 6 months, rated at 180,000 uses, on 4 AA alkaline batteries. A low voltage indication tells users when to change them.
What if the battery dies while nobody is watching the indicator?
There is a USB port for emergency charging, plus a mechanical key.
How much of the door has to be cut?
The lock uses an ultra-thin core specifically so the breakage to the door when making holes is as little as possible.
Which door materials does it suit?
Wood, steel, stainless steel and aluminium doors.
Will it work in a cold climate?
The working temperature range is -30 C to +65 C, and units pass high and low temperature, vibration and ageing tests.
