In this category, you’ll find stand-alone mechanical keyless locks that do not require any wiring or batteries. These keyless locks are designed for residential, commercial, or industrial use. Usually they can be installed in place of regular locks with only minor modification to the door. They are perfect for people who don’t like to use keys, or who tend to lose their keys. They only work with one code combination, as opposed to electronic keyless access locks that can be loaded with more than one code. They are extremely reliable, can withstand high traffic volume, and can be used on both interior and exterior doors.
