Korea #1 Digital Lock

Gateman A20-CH Digital Lock

Picture
The Gateman A20-CH digital lock is the epitome of good design: simple clean lines, slim front profile, matt black brushed surface that delivers an elegant overall look.

It is also heavily and robustly built compared to cheaper plasticky models.
​

Why Gateman A20-CH and not other brands? Other brands will not have Master Mode/Pin which prevents unauthorised changes to lock settings/registration. Only Gateman!

With pin and card access feature, it delivers consistently, it always work. We suggest this lock strongly for all kinds of doors and use cases, including room doors, storage places, small businesses doors, and especially for tenanted premises.
