worked perfectly
It took me less than a minute to replace this lock, and I kept the old screw from the door and it worked perfectly

perfect replacement fit for the Anderson storm door lock-key set
This was a perfect replacement fir for the Andersen storm door lock set. The QEM was almost three times more expensive as this replacement unit. Well made, sturdy nice looking product. Highly recommend this product

Changed key lock to thumb key.
Excellent quality. I changed my key lock over to thumb key. I went to a locksmith before my purchase. Locksmith said they had one for $80. I decided to give this a try! I'm glad I did. I did purchase my lock longer than my original key lock due to the fact that I wanted to make sure it passed the storm window glass.

Got broken in a few months
It is not worth it. The screw gets loose all the time, and eventually it just stops turning. Have to buy another one.

Easy peesy
Came quick & easy to install. My husband did in a matter of minutes. Our lock had broken & when we called the installer we were quoted $150 to replace the lock... no thank you-we got this!
