Safety 1st No-Drill Deadbolt Lock

This is one of the best childproofing locks for a deadbolt. There is no drilling, nor does it damage the door or lock. It was very easy to install, only taking 5 minutes to do so. My toddler boys always seem to figure out or break the childproofing items I have bought, but this item is hands down the best one out there on the market. Also, the seller shipped out the product faster than expected. I got it in two days instead of waiting a week.

It is very easy to install, and it completely blocks the deadbolt lock, making the process of opening the door extremely difficult for any of my children. Bought this because my three year old has been recently unlocking our backdoor to go outside without our knowledge, and he's completely stopped doing that ever since we installed thisndeadbolt lock.

Great safety product for toddlers!! I have a deadbolt my 2 year old learned how to unclock and ordered this and was super easy, probably one of the easiest safety 1st products I've used! Easy to assemble! Easy to use!

Easy to install and effective

I told my grandson it is to protect me from bad people so it's been working great

It works great to keep my autistic grandson in the house. Love it!!!!

it works great helps keep the kids in the house

The first one we bought got stuck and we were unable to turn it but we got a replacement and it has been great! The best part is that although my toddler figured out how it works the first day she can't physically operate it yet.

It works as a child safety lock but its ease of use is sub-par. It's stiff to turn and the latches will slip over the lock often requiring multiple attempts.

Easy to install. Lookwise it is very good. Little difficult to use. Not 100% secured.
