Need a hex commercial door key

[johninct]

I need a hex/ Allen wrench commercial door key to go onto a key chain. It is 5/32" or 4mm and used to lock a commercial door that is pushed to open. I do not know what they are specifically called or where to find one.

they are commonly called " dog or dogging keys"

 

[Crazyjake8493]

Yep, "dogging key" or "dog wrench." We have them on a lot of our doors, though some are dogged with the operator key.

A word of caution.

The cheap knock-off versions out there are often a bit too small.

They will work for a while, but will slowly wallow out the lock.
