Review: NOT SMART KEY - NOTE: it isn’t a smart key lock, as I discovered after I installed it. It was described correctly so it’s my fault for overlooking it. I have been changing locks throughout the house because of a very unruly juvenile. I’ll be more careful next time. It just means I have one more key to keep up with.
Review: Perfect! - Amazing quality, installation was easy (I swapped out two old deadlocks and this was a straight replacement), instructions are easy to follow, and everything was included in the box with a minimal amount of wasted packaging materials. Super happy with these Kwikset locks. I bought Kwikset entry door handles as well and was able to key all the doors alike. Much better and a better price than anything you’ll find at Bunnings.

### ⭐⭐⭐⭐⭐ NOT SMART KEY
*by G***Y on 11 January 2026*

NOTE: it isn’t a smart key lock, as I discovered after I installed it. It was described correctly so it’s my fault for overlooking it. I have been changing locks throughout the house because of a very unruly juvenile. I’ll be more careful next time. It just means I have one more key to keep up with.

### ⭐⭐⭐⭐⭐ Perfect!
*by T***M on 28 January 2026*

Amazing quality, installation was easy (I swapped out two old deadlocks and this was a straight replacement), instructions are easy to follow, and everything was included in the box with a minimal amount of wasted packaging materials. Super happy with these Kwikset locks. I bought Kwikset entry door handles as well and was able to key all the doors alike. Much better and a better price than anything you’ll find at Bunnings.

### ⭐⭐ Not a Smart Key lock like photo!
*by K***E on 22 July 2023*

The lock came fast and complete. This would get you 5 stars. However the photo they use to sell is a “Smart Key” where you can re-key yourself. As you can see in the photo there is no slot for the Smart Key tool. This gets you 2 Stars. BUYER BEWARE!
