Buying Guide
What to consider when choosing a sliding door digital lock
- Door compatibility: Check thickness range and frame width. Many models target 13/16″ to 4-3/4″ (22–120 mm) doors and frames of 1.6″–1.8″ or wider.
- Unlock methods: Decide which mix of fingerprint, passcode, RFID, app, and key backup you need. Consider how many users you’ll support and whether temporary access is important.
- Connectivity: Some locks require a 2.4 GHz Wi-Fi network for setup; others work via Bluetooth or local keypad without internet. Consider whether you need remote access or just local control.
- Power and backups: Battery life varies; check for low-power alerts and whether power-bank backups are supported for emergencies.
- Security features: Look for tamper alarms, lockout after failed attempts, and automatic relocking for added safety.
- Installation: Reversible handles and adjustable spindles help fit a range of door types. Ensure the mortise and lock dimensions align with your door’s construction.
- Multi-user management: If you’re renting or managing properties, verify how many digital keys or user profiles the lock supports and how to grant or revoke access quickly.
