Steel doors are the first layer of home security — but no matter how solid the door is, the security chain breaks if the lock is weak. In this article, we cover what to keep in mind when using a smart lock on a steel door.
Why are external-mount systems preferred?
For steel doors, smart lock systems that can be externally mounted without touching the existing cylinder mechanism are usually preferred. This approach preserves the door's original security structure while also speeding up installation.
The advantage of planning the door and lock together
If you're buying a new steel door, planning the lock together with the door — rather than afterward — guarantees installation compatibility from the start. This is exactly why ASUM TEKNOLOJİ is the official dealer of Falez Çelik Kapı: to offer a single-source solution without compatibility issues between door and lock.
Even if the door and lock are each excellent products on their own, compatibility issues can arise if they weren't planned together.
If you already have a steel door
If you'd like to install a smart lock on an existing steel door, the door's lock cavity and thickness need to match the model. Sharing a photo of your door speeds up determining the right model.
Maintenance and longevity
For smart locks mounted on steel doors, resistance to humidity and outdoor conditions matters. Models recommended for exterior doors have a different body and seal construction than indoor models — so telling us whether the lock will be on an interior or exterior door makes our recommendation more accurate.
