QuiC Q034+Smart Lock
Face recognition, palm vein, fingerprint, card or code, plus built-in Wi-Fi, a camera and video intercom, so you can see your door, talk to your visitors and open up from anywhere.

Built for 100% compatibility with doors in Türkiye.
Q034+ installs on monoblock lock doors by drilling only a single hole, and on central locking doors without any drilling at all. Fully compatible with steel, pivot and wooden doors.
What makes DESi different.
A smart lock is not an electronic gadget; it is a security system that directly affects your family's safety. That is why the real difference lies not in the device, but in the company behind it. DESi is one of Türkiye's largest smart lock manufacturers, built on 100% domestic capital and in-house engineering.
Proprietary, patented technology
Patented solutions from our own R&D, such as the virtual door handle and turn-count learning, have become benchmarks in the industry. Our designs are protected by design registration.
One of Türkiye's largest manufacturers
One of the largest manufacturers in its sector by production capacity and market share.
In-house R&D and software
Software, hardware and design are developed entirely in Türkiye by our own engineering team. Systems are continuously improved with software updates and security issues are addressed immediately.
Wide service network
One of the few companies able to provide on-site technical support across all 81 provinces of Türkiye.
Exporting to Europe
Used in more than 50 countries with CE certification and international security standards.
Spare parts guarantee

Comfort and aesthetics for a modern home.
Q034+ gives you the freedom to lock and unlock however suits the moment: face recognition, palm vein, fingerprint, card or password. Its always-on Wi-Fi lets you hold live video calls with visitors and keep an eye on your home from anywhere.

Learns its own rotation and stop point. (Patented)
Most smart locks, the Q032+ and Q034+ aside, strike the mechanical lock hard at the end of their travel when locking, which causes wear or breakage over time. DESi's rotation-learning technology finds the correct stopping point, eliminating that impact and protecting your mechanical lock.
Flexible access and authorisation options.
Up to 10 authorised users and 240 standard users, so you can set personalised permissions for family members or company staff, using palm vein, password, fingerprint, face recognition or card.

Virtual handle movement (Patented)
A light push of the inside handle in the locking or unlocking direction is all it takes. Q034+'s detection sensors read that first movement and complete the locking or unlocking for you.

Secured the moment the door closes.
As soon as the door closes, the system locks itself, keeping your home or workplace continuously protected. You can customise the auto-lock timing.

Watch your door, talk to your guests, open it from anywhere.
With connectivity built in, Q034+ keeps security at your fingertips. Unlock your door over the internet, hold a video intercom conversation with visitors, and watch the area outside your door in real time through the integrated camera.

Secure palm vein recognition.
An ideal answer for children who can't reach a camera: your child simply holds up a hand and the door opens.

Quality materials, built for outdoors.
A solid aluminium alloy body, IP54 protection and a total weight of 4 kg make Q034+ dependable for the long run. The multilingual menu, voice guidance and OLED screen keep daily use simple, and the battery charges through the Type-C port without being removed.
