Digital Locks

How to choose

• Start with how you unlock

  Fingerprint and PIN suit daily family use. RFID cards work well for staff or guests. App control adds remote access when connectivity is available. Face recognition is ideal for premium main doors. Keep a mechanical key as backup on most homes.

• Match the lock to the door

  Main wooden doors usually take mortise or rim locks. Glass and aluminium profile doors need models rated for those frames. Cabinet and secondary doors often use compact padlocks or slim units.

• Decide on connectivity

  Offline PIN and fingerprint work without Wi‑Fi. Choose Bluetooth or Wi‑Fi only if you need temporary codes, remote unlock or multi-user app management.

Compatibility

• Confirm door thickness (typically 35–55 mm for many residential locks) and whether the door is single or double leaf.
• Share material — solid wood, engineered, glass, or aluminium — so we can recommend the right body and strike.
• Check backset and handle height if replacing an existing lock; photos of both sides of the door help.
• Battery-powered locks need accessible battery compartments; emergency USB power is available on many models.

Installation

• Professional installation is recommended for secure fit, alignment and warranty support.
• Most replacements use existing door prep; new doors may need cutting for the lock body and strike.
• After fitment we guide you through user enrolment (fingerprints, PINs, cards) and basic app setup when applicable.
• Enquire with your city and door photos — Zen Circuit can quote supply, installation or both.
