Replaced expensive, but troublesome entrance locks with these in 3 locations without any serious difficulties. One installation required a call for help, but the technical support was excellent and got me on the right track quickly.
I can recommend this lock for anyone who wants to keep a doorway secure without worrying about keys.

The product was installed at our law office. While it appears rugged and easy to operate, it is very difficult to maintain the premises secure by routinely changing the combination to protect from individuals gaining access who no longer work at the office. There is no network of individuals to provide a combination changing service. So, if you are in a business that demands security and combination changes are necessary, this is NOT for you.

The lock would not work until my handyman called the company and figured out the cylinder was installed either backwards or upside down. Once he fixed it, it worked. Just thought you should know.

Paul from Michigan –
We have been using the Simplex 5021 model keypad in our food processing operation for more nearly two years now. With my previous brand’ a Codelocks 500′ I was replacing part of the lockset about every six months in my high-traffic area. I have not needed to repair or replace my first 5021in that same area in 22 months. I’ve outfitted my plant with 5021s throughout. No regrets.
