Frequently asked questions
How easy is the installation?
Installation is straightforward for gates already using a 3585 mortise lock, but minor modifications may be required depending on the existing cutout and hardware.
A drilling template is included if additional holes are needed. Professional installation is recommended if you are unfamiliar with gate hardware.
What is a 3585 mortise lock, and how do I measure mine?
A mortise lock is the lock body that sits inside the edge of the gate frame, behind a narrow metal plate. "3585" refers to two measurements: a 35 mm (about 1⅜″) backset from the edge of the gate to the center of the handle, and 85 mm (about 3⅜″) between the center of the handle and the center of the key cylinder. It is a common format in narrow-frame aluminum gates and doors.
How to measure your gate:
- Open the gate and look at its edge. A 3585 mortise has a metal faceplate about 22 mm (⅞″) wide with a latch and a deadbolt.
- Measure from the edge of the gate to the center of the handle spindle: 35 mm (1⅜″).
- Measure from the center of the handle spindle to the center of the key cylinder: 85 mm (3⅜″).
If both match, the Smart Lock fits, and a new 3585 mortise is included in the box. Not sure? Email us a photo of your gate's lock and edge, and we'll confirm the fit before you order.
Will it work on my gate?
This lock is a retrofit replacement and requires an existing mortise lock (keyed or electronic) already installed in your gate. If your gate does not currently have a mortise installed, this lock will not be compatible. Compare your cutout with the 3585 mortise dimensions (35 mm backset, 85 mm centers), or email us a photo of your gate's lock and we'll confirm the fit before you order.
Will this lock work for my patio or front door?
Only if the door already has a 3585 mortise lock installed. It won't work on sliding doors. Not sure what your door has? Email us a photo and we'll take a look.
Can you install this lock for me?
If you are located in Southern California, that is a possibility. Email us your request with your location and a picture of your gate.
Is this an alternative to the Alumalock?
Yes. Customers often choose this lock when they want a similar aluminum gate lock function with different pricing and more features. It fits common aluminum pedestrian gate profiles. See the Alumalock comparison.
Does this lock fit standard aluminum pedestrian gates?
Yes. This smart aluminum gate lock is designed around common aluminum pedestrian gate profiles used in residential and light-commercial installations. It is compatible with the majority of welded or modular aluminum gate frames used in backyard and side-yard applications.
Why do customers choose this over other aluminum gate locks?
Customers often choose this lock for its balance of durability, clean installation, and cost. It provides the same core function as many well-known aluminum gate locks, while offering straightforward installation and reliable daily use without unnecessary complexity.
What happens if the batteries run out or the power goes off?
The lock runs on 4 AAA batteries, so a power outage doesn't affect it. If the batteries run flat, use one of the two mechanical override keys, or power the lock temporarily through the USB port on the outside panel.
Can I open the gate remotely?
Within Bluetooth range you can unlock from the TTLock app. For remote access from anywhere, pair the lock with a TTLock Wi-Fi gateway (sold separately).
What is the warranty?
This Smart Lock comes with a 1-year warranty. Unused, uninstalled locks can be returned within 30 days of delivery, and defective locks are replaced or refunded within 30 days. See our return policy.
