Frequently Asked Questions
Q: Does the TTlock K2/K2F work without a Wi-Fi gateway?
A: Yes. The K2 and K2F both operate via Bluetooth 4.1, so you can unlock the door using the TTlock smartphone app within Bluetooth range without any gateway. However, for remote access and management from outside Bluetooth range, the optional Wi-Fi gateway (compatible with K2F) is required.
Q: What RFID card standard does this access controller use?
A: The system uses the 13.56 MHz RFID standard (commonly associated with Mifare and ISO 14443 cards). It supports up to 20,000 cards, making it suitable for large-scale deployments like apartment complexes or commercial offices.
Q: Can I set time-limited access for guests or temporary staff?
A: Absolutely. Through the TTlock app, administrators can create time-restricted passcodes and eKeys that are only valid during a set date/time window. Once the period expires, access is automatically revoked — no manual intervention needed.
Q: What is the difference between the K2 and the K2F models?
A: The primary differences are the waterproof rating (K2 is IP66; K2F is IP65) and the K2F's support for fingerprint reader functionality and Wi-Fi gateway connectivity for remote management. Both models share the same core app, card, and keypad access methods.
Q: Is the TTlock K2/K2F suitable for outdoor installation?
A: Yes. Both variants carry high IP waterproof ratings — IP66 for the K2 (dust-tight and protected against powerful water jets) and IP65 for the K2F (dust-tight and protected against water jets), making them well-suited for outdoor gates, building entrances, and covered external doors.
