C1B Electronic Cylinder

The C1B electronic cylinder is a modern solution that combines elegant design with advanced access-control technology. It supports every popular access method: fingerprint, TTLock mobile app over Bluetooth, Mifare proximity card and PIN code. Every method can be granted or revoked from the app — creating permanent, time-based, one-time or recurring access. A perfect choice for those who value convenience and security but don't want to interfere with the door itself.

A huge advantage of the C1B is that it drops into the place of a standard euro cylinder — no need to replace the whole door, no drilling, no wiring. Installation typically takes 15–30 minutes and is fully reversible, which makes it attractive for tenants and anyone who wants to upgrade existing doors quickly. The cylinder has an IP55 rating, so it works on interior doors and on many exterior doors exposed to dust, humidity and temperature swings.

Memory holds up to 200 fingerprints, 200 proximity cards and 200 individual PIN codes, while the number of e-keys generated in the TTLock app is virtually unlimited. Power comes from four AAA batteries that last 8–12 months of daily use, and the app warns you in advance about low battery. If the batteries fully drain, you can temporarily power the cylinder from a USB power bank and open the door. Browse the rest of our electronic door locks and fingerprint locks.
