Frequently asked questions
How does an electronic rim lock work?
It fixes on the inside face of a gate or door. The motor retracts the latch when you press a remote or use the app, and the latch locks again when the gate closes. A key cylinder gives a manual backup.
Will it fit my gate?
Rim locks mount on most metal and wooden gates and doors that open inward or outward. Check the lock dimensions and the opening direction listed in the product details.
What happens in a power cut?
Use the key to open the lock by hand. A battery backup power supply can be added to keep the remotes working.
Is a GST invoice provided?
Yes. NavKar Systems provides a GST invoice with every order and delivers across India.
Is technical support available?
Yes. Free technical support is available for installation and setup.
