Security from both inside and outside! 【Keylex Double-Sided Button Series】

Ideal for places where you want to restrict not only external intrusions but also internal exits! You can set separate PIN codes for inside and outside!

The "Keylex Double-Sided Button Series" features button locks (Keylex) on both the inside and outside of the door, allowing for access control via a passcode whether entering from indoors or exiting outdoors. You can set different passcodes for the inside Keylex and the outside Keylex, enabling you to have two separate passcodes: one for entry and one for exit. (Of course, you can also use the same code for both sides.) Each Keylex comes with a double-sided button option, allowing you to use it according to your needs. For example... - I want an auto-lock feature or one with a key (*1)! - I want to change the passcode without removing it from the door! - I prefer a compact type! - I want to use it for sliding doors! We have a wide variety of options to meet various requests. *For more details, please refer to the PDF document or feel free to contact us. (*1) Keyed: This type has a cylinder built into the Keylex body, allowing it to be unlocked not only by the button but also with a key.
