This keyless deadbolt does not have a back plate! Am I supposed to leave an open hole on the outside of the door! What a rip off!

Fits great and looks good (polished brass). It’s an exact replacement for what was installed in the door. Be careful to not over tighten the machine screws that secure the plate to the tumbler assembly- it’s plastic that the screws anchor into.

This is a blind dead bolt (thumb turn on the inside only, blank on the outside). Required in some jurisdictions for rental property. Kwikset brand, works great, and value priced. Have seen these in silver, polished brass, antique brass and antiqued copper (black)

I love how easy it is to install – it took me just a few minutes to set it up without any hassle. The unkeyed design is perfect for situations where keyless entry is preferred, providing convenient access without the need for keys.The build quality is top-notch, as expected from Kwikset. The lock feels solid and durable, giving me peace of mind knowing that my home is secure.One thing to note is that it's always locked from the outside, so you'll need to remember to keep it unlocked when you're not at home to avoid getting locked out.Overall, I'm very satisfied with the Kwikset 663 Deadbolt Unkeyed Deadbolt Lock. It's reliable, easy to use, and provides the security I need for my home. Five stars!

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.

En la descripción deberían mencionar que solo funciona para puertas de madera y delgadas; yo lo quise poner en puerta metálica con 4.2 cm de grosor y no quedó porque no queda fijo y al momento de apretar para fijarlo se tuerce y la perilla queda dura.Por lo tanto, tomen en cuenta que donde piensen colocarlo sea una puerta de madera, no ten gruesa donde el cilindro pueda quedar fijo y no bailando en el hueco.

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.

I really like this product, though I wish it was a little heavier, it's lighter than the other kwikset deadbolt that I purchased. The only problem I ran into with this single-sided dead bolt was that the plastic piece which allows the screws to hold it in place was too long for the existing hole that I had. I had to drill an additional hole for this item - the problem wasn't drilling the hole it's the concern I have regarding this product breaking like it did last time. The reason I needed a new one was the old thumb turn broke and just spun in place instead of unlocking the door. We were able to open the lock and slide it out from inside the house. Now that I've drilled it securely in place, if this issue were to ever happen again, I'd have no way of sliding it out. For those in a similar situation, be aware that if this lock were to break while it's locked, you're going to have to cause considerable damage to the inside of your door to get it back out.
