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

Thanks for your question! The B200 Set uses an **SC1 keyway (5-pin Schlage C style)** for its physical backup key. SC1 is a common residential key type, making replacement key blanks easy to find through most locksmiths and key-cutting services.

Hi Lis, B200 is designed to replace a standard deadbolt, so your door will need a deadbolt setup for installation. If your door does not currently have a deadbolt, you can still use B200, but you’ll need to add the required door and door-frame holes first. We recommend having a locksmith or professional installer prepare the door to ensure proper alignment and installation.

Yes. The B200 is designed for year-round outdoor use and operates in temperatures from -22°F to 158°F (-30°C to 70°C). It also features an IP54 water-resistant rating for everyday protection against rain and snow. Like all battery-powered devices, extremely cold temperatures may reduce battery life, so it's a good idea to replace the batteries when you receive a low-battery alert.

Yes. When connected to the TTLock app via Bluetooth, you can view the lock's activity history, including unlock records and timestamps. If you add the DESLOC G2 Wi-Fi Gateway (sold separately), you can also check these records remotely when you're away from home.

For most standard U.S. front doors, installation is a straightforward DIY project. If you're replacing an existing deadbolt and handleset with standard door preparations, you can usually install the B200 using only a screwdriver. Printed and digital installation guides are included to help you through the process.
