TTLock connected lock: who it suits

This article was machine-translated from French and is being reviewed. Prices are in Algerian dinars excl. VAT.

TTLock is an ecosystem of locks and access controllers driven by a mobile app, published by the Chinese company Hangzhou Sciener. The products communicate with the phone via Bluetooth LERemote unlocking also requires a Wi‑Fi gateway.This guide explains what a TTLock smart lock does, what it doesn’t do, and which uses it is suitable for.

How TTLock works

• The phone and the lock communicate via Bluetooth LE. The administrator uses the TTLock app (iOS, Android). The TTLock account records access rights, codes and histories in the cloud.
• Opening methods: app on phone (electronic key or “eKey”), keypad code, Mifare card, fingerprint depending on model. Cards and fingerprints are registered directly on the lock via the app and verified locally.
• No bridge, everything works via Bluetooth. A change made in the app (new code, card removal) reaches the lock only when a phone from the account is in range.
• With a Wi‑Fi gateway (type G2), you can open remotely, send a code remotely, view the lock status and the history is automatically logged. The gateway connects to your Wi‑Fi network: place it on a separate network from your workstations, as explained in secure an invited Wi‑Fi. It is not listed in the price list of the store on 06/11/2026: it is requested during the quote.
• The codes can be permanent, time‑limited, single‑use or cyclic (e.g., every weekday). Codes generated by the app are calculated from the lock’s clock: they work offline. According to TTLock documentation, a random time‑limited code must be entered once on the keypad within 24 hours of its start, otherwise it becomes invalid. A custom code has no such constraint, but must be transmitted to the lock via Bluetooth or the gateway.
• The lock clock counts: if it drifts, a correct code may be rejected. Check it during commissioning and whenever batteries are changed.
• The history is kept in the lock’s memory. It syncs to the app on the next Bluetooth connection, or automatically via a gateway.

TTLock products from the AsloTech store

GL5T: frameless glass door lock

Product sheet: TTLock GL5T lock

Price: 34,000 DA HT (price on asloitech.com as of 06/11/2026, subject to availability).

The store sheet does not detail specifications. The points below come from reseller listings for this reference; the manufacturer’s sheet is authoritative:

• Opening by fingerprint (up to 100 claimed), code, Mifare 13.56 MHz card and app.
• Mounting by tightening on a frameless glass sash, for thickness 8–12 mm.
• Power by 4 AA batteries, with a USB port for backup power. No mechanical key is mentioned.
• Bluetooth range advertised 5–10 m. Battery life advertised 6–12 months depending on use, with low‑battery alarm.

Suitable for: office, office suite or meeting room with frameless glass door.

Check before buying: exact glass thickness, sash orientation and type, how the door opens from inside, and the emergency procedure if batteries are dead and no USB power is reachable.

S7-BLE: mini access controller for solid door

Product sheet: TTLock S7-BLE mini access controller

Price: 13,500 DA HT (price on asloitech.com as of 06/11/2026, subject to availability).

According to the manufacturer’s sheet (Secukey), the S7-BLE is a 73 mm diameter enclosure, with touch keypad and card reader:

• 12 V DC power (consumption up to 80 mA). No batteries.
• Lock command output up to 2 A.
• Mifare 13.56 MHz cards, up to 1,000 users, Bluetooth LE, gateway compatible.
• IP66 rating and operating range –20 to +60 °C.

It does not lock anything by itself. It commands a relay to control a electric latch or a suction cup 12 V that, in turn, holds the door. A 12 V power supply, a cable between the supply, controller and lock, and a way to open the door from inside are required. Connecting the power supply to 230 V mains is a qualified electrician’s job.

What does a door do without power? A suction cup releases. An electromagnetic latch stays locked. Battery backup avoids most of these situations; if you plan a UPS, see UPS: how to choose the power. For choosing between suction cup and latch, see electromagnetic lock or electric latch.

Hardware budget for a door with S7-BLE (approximate, excluding cards, cable and installation):

• S7‑BLE: 13,500 DA HT (store price).
• Electric latch from the range we install (AL135NC): 8,500 DA HT, median observed on our quotes (6 orders).
• 12 V 5 A power supply for access control: 5,900 DA HT, median observed on our quotes (18 orders).
• Total: 13,500 + 8,500 + 5,900 = 27,900 DA HT.

Variant with a 350 kg suction cup instead of the latch. The suction cup alone costs about 8,000 DA HT (median of our quotes for the 350 kg suction cup: 8,710 DA HT). With its L‑bracket support, expect about 16,000 DA HT: the shop lists 16,500 DA HT for the 350 kg ZKTECO electromagnetic lock (price from asloitech.com on 06/11/2026, subject to availability). The total becomes about 13,500 + 8,000 + 5,900 = 27,400 DA HT with the suction cup alone, and about 13,500 + 16,000 + 5,900 = 35,400 DA HT with its support, excluding cards, cable and installation.

Cards and badges

The S7-BLE and GL5T read Mifare 13.56 MHz cards. 125 kHz (EM) cards are not read. The shop sells a PVC Mifare 4K 13.56 MHz card, listed at 150 DA HT, marked “200 per box”: confirm the sales unit before ordering. The shop’s 125 kHz USB RFID reader is not intended for these products and is useless to register them: cards are added via the lock, from the app.

Usage examples

Office with a glass door. A GL5T equips the entrance door. Each employee has a fingerprint or card. A contractor receives a time‑limited code that expires automatically. If the administrator also wants remote opening, they add a gateway.

Technical room. An S7‑BLE controls a latch or suction cup on the door of the room containing the server, UPS and network rack. Access is by card or app, with a history.

Short‑term rental. Each stay receives a time‑limited code. Create it shortly before arrival, and remind the traveler to enter it once on the keypad within 24 h. In our shop record, we have no TTLock lock to embed on a full door: an S7-BLE with latch works, but it requires a 12 V supply nearby.

Limits and points to clarify

• No centralized system. A TTLock account manages several locks, but each operates independently, without a local controller or server. For many doors and users, wired access control is more suitable. We do not present TTLock as an access control solution for sensitive sites.
• Internet and cloud. Without internet, remote management stops, but opening by code, card or fingerprint continues. Data goes through the manufacturer’s cloud; the exact location of its servers is not published. Read its privacy policy.
• Personal data. An opening history associates a name with a time. Inform users. For the framework of data protection, see client obligations in CCTV. AsloTech can help you prepare the procedures with ANPDP (National Authority for Personal Data Protection); this assistance is not legal advice.
• Power. Replace batteries when the low‑battery alarm sounds and keep spare batteries. For a 12 V controller, a battery backup avoids shutdown during a power outage.
• Emergency exits. On an evacuation route, the door must open from the inside at all times, without batteries and without a phone. Have the device approved before installation.
• Installation. A lock on an existing frame requires adjustments. A technical visit is recommended.
