Overview

Adding a keypad to a standard knob position, this iulock set swaps the old knob for a lock with a touch keypad and a keyed override. It is waterproof, auto-locking and finished in matte black.

Fifty codes and auto-lock make it simple to give access to family, guests or staff without handing out keys. The limit is fit, since the listing gives no backset, door thickness range or bore size.

Who it's for

Interior or exterior doors with a standard knob, such as a side entry or workshop, suit this lock. A buyer who wants app control, a deadbolt or a verified door fit should look at a different model.

Pros and cons

Pros
  • Many user codes
  • Mechanical key backup
Cons
  • Backset not listed
  • Door thickness not stated
  • No app control
  • Battery type not listed

Performance notes

The keypad accepts a stored code and releases the knob, while a mechanical key handles power loss. Auto lock re-secures the door after a set time, and waterproofing protects the keypad when the door is used outdoors.
