The answer to my security questions.

I have a commercial property with the necessary mailbox. The problem with the mail slot is that the door could be opened through the mail slot with the right tools. As this is a commercial listing I was not allowed to install a two key deadbolt which is against fire codes. Even if it's only locked outside of working hours. So I had an issue that bothered me every time I left, it was always on my mind. I read about 200 reviews on this and others. I thought it was a commercial cinder block door so it might be too small. But I dared and BINGO! Also worked great. I no longer have to worry about someone gaining access through the mailbox. I installed it and used the tools and couldn't open it. What a relief. The o-ring is tight and when that becomes a problem I install a metal e-clip to hold the cylinder in place. I couldn't be happier. I'm updating the information about it becoming buggy with new information. Buy with confidence knowing your commercial building owners will fit the Schlage Front Door Handle!

Pros

DOOR HANDLE LOCK - The Defender security door handle lock can be fitted directly over the door handle to prevent access to the keyhole.

Cons

Questionable purchase for seniors
