Choosing the right lock

Start by identifying your door type (hinged, sliding, glass, or gate) and measuring the thickness of the door and latch spacing. Uploading clear photos of your door (front, back, and edge) through our form helps our team recommend the best compatible lock for you.

A mortice lock fits inside a pocket cut into the edge of the door - typically used for front or heavy-duty doors. A tubular latch is simpler and more common for internal or light-use doors. Choosing the right one ensures a smooth and secure installation.

Every door is different. Uploading photos lets our experts check your existing setup, latch size, and handle spacing to make sure you order a lock that fits perfectly. It prevents mistakes, avoids returns, and ensures your smart lock installs cleanly the first time.

We recommend three clear photos taken in good lighting:

• The front of your door (showing the handle and keyhole)
• The back of your door (inside view)
• The edge of the door (showing thickness and latch position)

This information helps us assess compatibility and recommend the right model.

If you don’t upload photos, we can’t guarantee compatibility. Since every door setup is unique, purchasing without confirmation means you assume responsibility if the lock doesn’t fit. We strongly recommend using our free photo check service before buying.

If your lock doesn’t fit because photos weren’t provided for review, Vault cannot take responsibility for incorrect compatibility. However, our team can help identify a suitable alternative and guide you through the exchange process if needed.

Check your door’s material, thickness, and latch type. Decide whether you want features like fingerprint access, facial recognition, or Wi-Fi control. Sending photos to our team ensures your chosen model is both compatible and functional.
