Wyze Lock Bolt

Fingerprint and keypad access. For fingerprint or keypad entry with a replacement deadbolt. Confirm door fit first. Replaces the deadbolt; check door measurements and connectivity.

SwitchBot Lock Ultra

Retrofitting compatible existing locks. For a retrofit lock setup. Check cylinder fit and the accessories needed for remote access. Verify cylinder compatibility, included accessories and hub requirements.

Fit comes before features

Check door thickness, lock type, permitted modifications and emergency access before ordering. A retrofit mechanism and a replacement deadbolt solve different installation problems. Compare the complete bundle price, including any keypad or hub you need, rather than the headline price alone.

Frequently asked questions

Will a smart lock fit my existing door?

Fit depends on the lock type, cylinder and door measurements. Check the exact manufacturer compatibility guide before choosing a retrofit lock or a replacement deadbolt.

Does a smart lock need Wi-Fi?

Connectivity varies by model. Local entry and remote control are different functions, so check which features work locally and whether remote access requires a hub.

What is the difference between retrofit and replacement locks?

A retrofit mechanism works with compatible existing lock hardware. A replacement model changes the deadbolt or lock assembly, so installation and door-fit requirements differ.

What should I check for backup access?

Check the exact model’s emergency power and backup-entry options before installation. Keep a practical entry plan for a depleted battery or an unavailable phone.
