DESLOC - B200 Smart Lock Keyless Entry Fingerprint Deadbolt with Handle/Lever Set, Front Door Replacement, Bluetooth App - Black - Knob Lever

The choice mainly comes down to your door style and personal preference. The knob version offers a classic look that matches many traditional homes and existing door hardware. It includes the same smart features as the lever versions, including fingerprint unlock, PIN access, the TTLock app, Auto Lock, and optional remote access with the DESLOC G2 Wi-Fi Gateway (sold separately). If you prefer the feel and appearance of a round door knob, this version is a great fit.

The B200 is designed for exterior residential doors and features an IP54 water-resistant rating for everyday outdoor use. Under normal residential conditions, the finish is designed to withstand regular exposure to weather. Like any exterior door hardware, its appearance can be affected over time by factors such as direct sunlight, coastal environments, or harsh cleaning products. Regular cleaning with a soft cloth and mild cleaner can help keep the finish looking its best.

Yes. The B200 is designed for exterior residential doors and is rated IP54 for weather resistance. It operates in temperatures from -22°F to 158°F (-30°C to 70°C), making it suitable for everyday use in rain, snow, and hot weather.

The lock works best when the door is properly aligned. If the deadbolt doesn't line up with the strike plate, it may not extend or retract smoothly. In many cases, a small adjustment to the strike plate or latch alignment will improve operation.

No worry. The B200 includes an Auto Lock feature that can automatically lock the door after it closes. You can enable and adjust the Auto Lock settings through the TTLock app.
