Zanda Stealth Longplate Smart Lock - 35mm Backset - Mortice

Zanda Stealth Smart Longplate - 35mm Backset - Mortice

The Zanda Stealth Longplate Smart Lock (Item Code: 1325) is a Bluetooth-enabled mortice lever lock for residential timber and aluminium doors, built on a 35mm backset mortice body. It is a complete smart lock set - lever handles are integrated on both the external keypad panel and the internal back panel, so no separate pull handle or passage set is required. It is managed via the TTLock mobile app (iOS and Android) and offers Bluetooth, PIN code, RFID card, fingerprint (optional) and mechanical key access. See Chapter 14 - the TTLock Platform Guide.

This 35mm-backset version suits narrower stiles than the 60mm mortice (1326); the lever operates the mortice latch for day-to-day entry while the smart credentials control access, with an auto-lock option to re-secure the door. The lock is IP66-rated for dust and water-jet resistance, making it suitable for external and weather-affected entry doors.

The lock runs standalone via Bluetooth in range; remote access, history review and credential management are available when it is paired with a compatible Zanda Wi-Fi gateway (sold separately). It suits doors 35-65mm thick, is supplied in four finishes, and is covered by the Zanda mechanical warranty (term varies by product and finish - see the Warranty section below).

Zanda Stealth Smart Range - Item Code Family

The Stealth range shares one app, credential set and optional Wi-Fi gateway, differing mechanically in body style, backset and installation method. This 1325 is the 35mm mortice longplate; the 1326 is the 60mm mortice version, the 1327 is the tubular-latch longplate, and the 1320 is a bolt-only deadbolt. If backset or door thickness is a live decision, see Chapter 02 - Measuring Your Door.

Accessories & Spares

• Zanda Stealth Electronic Lock Gateway / Wi-Fi Bridge (STK 1330.-) - the optional Wi-Fi bridge that adds remote access, remote credential management and remote history review. Without it the lock still runs fully via Bluetooth, PIN, card, fingerprint (if fitted) and key. See do you need a gateway?
• 4 x AA batteries - required to power the lock; not supplied. Use quality alkaline cells.

Frequently Asked Questions

Do I need a separate handle with this lock?
No. The Stealth Longplate is a complete lock set with lever handles on both the external and internal panels - no separate pull handle or passage set is required. See Chapter 01 - mortice lever locks.

What does the 35mm backset mean, and how is it different from the 1326?
Backset is the distance from the door edge to the centre of the lock spindle. This 1325 uses a 35mm backset (suited to narrower stiles); the 1326 uses a 60mm backset. Externally the longplate is identical. See how to measure backset.

Does this lock connect directly to Wi-Fi?
No. It uses Bluetooth. Remote access needs the Zanda Stealth Wi-Fi gateway bridging the lock to the TTLock app. Chapter 08 explains what a gateway adds.

How do I set the lever handle direction?
The lever direction on both panels is adjustable before installation - loosen the inner hex screw, remove and re-seat the handle, then re-tighten; the square shaft is set to suit door thickness and handing. See determining door handing and Chapter 02 - handing.

What happens if the wrong PIN is entered too many times?
After five wrong entries in a row the keypad locks out for 5 minutes. The door can still be opened with an RFID card, fingerprint (if fitted) or mechanical key during that time. See how PIN access works.

Does this suit aluminium doors?
Yes - timber and aluminium. The kit includes separate screws for each door type and waterproof rubber plates on both faces. See Chapter 04 - Door Type Compatibility.

Additional Information

Complete lever set (no separate handle)
The 1325 incorporates lever handles on both panels and operates the mortice latch directly, so it is the primary door hardware. Where a heavier security throw is wanted, a separate deadbolt can be specified alongside - see what a mortice lever lock is and secondary locks and the one-penetration principle.

Handle direction adjustment
Set the lever to match the door open direction during installation, and fit the correct square shaft (60mm or 80mm supplied) for the door thickness. Confirm the open direction before drilling - Chapter 02 - handing.

IP66 weather resistance
IP66 confirms the lock is dust-tight and resistant to powerful water jets from any direction, suiting external and weather-affected doors. It is not fully submersible - avoid direct immersion. See Chapter 11 - IP ratings, and for coastal longevity the realities of electronic door locks.

TTLock default password
All new Zanda Stealth locks ship with a default TTLock password of 123456 - change it immediately after installation. The lock is added to the app via Bluetooth, which must be enabled during pairing. See the TTLock app user manual and Chapter 14.

Fingerprint registration
For reliable enrolment, ensure fingers are clean and dry. Each fingerprint can be given a start and end time for time-limited access. If the sensor is unresponsive it should still beep when pressed; if not, check the wire between the front and back panels. More on fingerprint access.

Warranty
Backed by the Zanda mechanical warranty against manufacturing defects in materials and workmanship under normal domestic use. Warranty length varies by product and finish - see the Zanda Warranty document for the term that applies to this item. Proof of purchase required for all claims. Zanda Warranty · Returns & Warranty
