"An $18 keypad lock offering basic convenience, but not meaningful residential security."
The 'ANSI Grade 3' certification means this lock meets the minimum residential standard for security. It is not designed to withstand a determined forced entry attempt like a Grade 2 or Grade 1 lock.
This product is for low-security interior doors, such as a pantry or home office, where keypad convenience is the only requirement. It could also serve as a temporary lock for a shed where it is not the primary security measure.
Anyone securing a home's front door, an apartment, or any space containing valuables should avoid this. The minimal security rating and questionable durability of an unknown brand make it a liability for genuine security.
