Product information

Make everyday access more convenient with the Zen Series 3 Digital Lock. Unlock using a fingerprint, RFID card, six-digit PIN or mechanical key. Its Wi-Fi connection lets you use the Smart Life app to remotely unlock when someone presses the lock’s bell button, create OTPs, receive unlocking notifications, associate names with users and review one month of access history. The lock stores up to 100 fingerprints, 100 RFID cards and 100 six-digit PINs. Two RFID cards and two mechanical keys are included. The app supports Android and iPhone, with unlimited users. Additional security features include automatic locking, alerts after more than three incorrect fingerprint or PIN attempts, a siren and mobile notification if someone tries to remove the lock, PIN hiding, low-battery alerts and lost-card cancellation. Emergency power can be supplied by a power bank while batteries remain inside the lock. If the batteries are removed, the mechanical key is the only way to unlock it.

FAQs

Answers relevant to this category — ask us on WhatsApp for model-specific detail.

A smart lock replaces or works with your existing door hardware so you can unlock with PIN, fingerprint, card, app or key — without relying only on a mechanical key.

It depends on the model. Many locks work offline with PIN and fingerprint; Wi-Fi or Bluetooth is only needed for remote app features. We’ll confirm connectivity for the product you choose.

Most digital locks give a low-battery warning well in advance. Emergency power (USB / Type-C) or a mechanical key override is available on many models so you’re never locked out.

Compatibility depends on door thickness, type (single/double), and material. Share a photo or measurements and our team will recommend a fit.

We recommend professional installation for a secure fit and warranty support. Zen Circuit can guide you or connect you with an installer for your city.
