Is It Possible to Install SwitchBot Lock on a Steel Door?

Yes, SwitchBot Lock (including Lock Pro and Lock Ultra) can be installed on metal doors. However, since the lock uses a magnetic sensor, the door's metal material may occasionally interfere with the auto-lock function.

If this occurs, try repositioning the magnet 10-20mm farther than the default distance. For example:

Default spacing: 20mm from the Lock

Adjusted spacing: 30~40mm from the lock

This adjustment often resolves detection issues while maintaining reliability.
