Smart lock fit
Compare retrofit locks, replacement deadbolts, and handle-style options before changing hardware, keyways, or keypad access on an existing door.
This smart lock core is for homeowners who want to upgrade their existing mechanical lock without a full replacement. It's perfect for adding keyless entry to your front door, so you can let in a neighbor to feed your pet while you're at work. While many locks focus on security, this one offers the convenience of never fumbling for keys again.
The fingerprint scanner recognizes your touch in under a second, even with wet hands from groceries. You can set temporary codes for guests that expire automatically, and the app sends alerts when someone enters. With a 180-day battery life, you'll rarely need to charge it, and the Type-C emergency port ensures you're never locked out.
