5.0 out of 5 stars Piece of mind
Reviewed in the United States on February 27, 2024
Color Name: Satin NickelVerified Purchase
This appears to be a durable inexpensive lock. We have a condo whereby the office maintains keys to get into our unit. We understand in a condo complex the office maintains keys to all the units but we are concerned because you just never know who might take advantage of the office set of keys and enter our unit without authorization. My partner wanted a security lock whereby no one could enter the unit while we’re sleeping. This lock was the perfect answer. It’s inexpensive and it’s a decent quality deadbolt. And since there’s no outside tumbler the door can only be locked/unlocked from the inside. Piece of mind for short money.

My old dead bolt broke and I wanted a cheap replacement that could be delivered quickly. It fit, it works and was easy to install. It, however, just like my old deadbolt, has plastic parts inside and will likely only last a few years as well. For now, it works and it was cheap.

I wanted a dead bolt lock for french door. If the key enter was visible on the outside, the glass would be broken to unlock it. This solves that problem. However the latch did not come with an extra plate and long screws to reach the stud. I think that this is because the door itself would break before the door frame would. It was easy to install with the right tools,

The description fails to mention you need to purchase a separate backing with a key. Bought a fill in cover plate at my hardware store and threw this out. Thankfully it was only $3.
There should be a warning it cannot be installed on its own.
