I gave 5 stars to Tech Support even though I didn’t need any. ( Everything else was so perfect that I didn’t have the heart to grade less.)
I installed it on a wrought iron gate. Because you can reach right thru the gate, I took it upon myself to hack-saw off the thumb turner – at my own risk of ruining the lock. But it worked great, so for those who might be afraid someone could break a close-by window and reach in and unlock it, there is your solution. Just be aware that if you want to unlock it from the inside, you will have to come up with a solution such as to saw a slot in the residual thumb turner post and use a screw driver. For me, I just reach thru between the pickets and enter a code.
Imagine: You can set 10 different codes! One for the pool guy, one for the gardener, one for the maid, one for your favorite neighbor, etc. You can also set “one time use” code, like for the occasional repairman. Tip: The coding instructions are excellent, so follow them closely. The same goes for installing the lock.
