JAIFY DLBS-Q20-PRO Smart Fingerprint Door Lock with Handle

JAIFY DLBS-Q20-PRO Smart Fingerprint Door Lock

Make your door smarter without making access complicated.

The JAIFY DLBS-Q20-PRO is a modern smart fingerprint door lock with handle designed for convenient, keyless access at home, in the office, or at rental properties.

Instead of relying on a traditional key, you can unlock the door using your fingerprint, PIN code, MIFARE card, temporary password, JAIFY app via Bluetooth, or emergency mechanical key.

The built-in handle gives the lock a familiar feel, while smart access management provides greater flexibility for households, businesses, apartments, and short-let properties.

Multiple Ways to Unlock

Choose the access method that suits you:

• Fingerprint
• PIN/passcode
• MIFARE card
• Temporary password
• JAIFY app via Bluetooth
• Emergency mechanical key

This gives family members, staff, tenants, and guests convenient access without requiring everyone to carry a physical key.

Fast Fingerprint Access

The DLBS-Q20-PRO uses a semiconductor fingerprint sensor with a stated matching time of less than 0.3 seconds.

With fingerprint access, your door can be unlocked with a simple touch rather than entering a PIN or searching for a key. JAIFY specifies a 500 DPI fingerprint sensor and a false-rejection figure below 0.15% in its detailed specifications.

Smart Access Through the JAIFY App

Connect the lock to the JAIFY app and manage access from your smartphone.

The app supports access management and entry-log review, while Bluetooth provides short-range configuration and unlocking.

Temporary & Time-Limited Access

Need to give someone temporary access?

The DLBS-Q20-PRO supports different password types, including permanent, one-time, recurring, and time-limited passwords.

This is particularly useful for:

• Guests
• Domestic staff
• Office workers
• Contractors
• Tenants
• Short-let properties
• Service providers

Virtual PIN Protection

Protect your password from people watching you enter it.

The virtual/decoy digit feature allows you to enter additional numbers before or after your real PIN. The system can recognise the correct password within the longer sequence, helping reduce the risk of someone learning your actual PIN by observation. JAIFY specifies a normal password length of 6–10 digits and a maximum virtual-key input of 16 digits.

Advanced Door Security

The DLBS-Q20-PRO combines several security features in one lock:

• Class C genuine lock cylinder
• Dual-factor authentication
• Lock trial-error alarm
• Anti-pry alarm
• Low-voltage warning
• Lock-body status monitoring
• Emergency mechanical unlocking

These features provide multiple layers of protection while retaining a mechanical backup option.

Automatic Locking Bolt

The lock’s bolt automatically extends to help secure the door after you leave.

That means you don’t have to rely entirely on remembering to manually lock the door every time you exit.

Built-In Electronic Doorbell

The DLBS-Q20-PRO also includes an electronic doorbell.

Visitors can press the doorbell button to alert occupants, adding another practical feature to the smart lock.

Easy-to-Replace AA Batteries

The lock uses 4 × AA batteries, which are widely available and easy to replace.

JAIFY also provides a 5V USB Type-C emergency power input, giving you an alternative power source if the batteries become depleted.

Designed for a Wide Range of Doors

The DLBS-Q20-PRO is specified for doors approximately 50–100 mm thick.

The lock uses a 6068 double-open, double-active lock body and does not require separate left- or right-hand door-opening selection according to JAIFY’s specifications. Some configurations may require an extra-long square bolt, so door compatibility should be confirmed before installation.
