No, you cannot lock out the code with a key. You would need to go to an electronic lock with scheduling features that would allow you to lock out codes at certain times.

This wasn’t the easiest lock to install but it was well worth the struggle. It’s exactly what we needed; it looks great and so far is performing well.

Hannelore –
The basic product was great however, we were not advised that we had to obtain a cylinder to override the numbers in case of ermergency. That was a little tricky since we live in a very small community in British Columbia and these things are not easily obtained. BUT we prevailed and all is well now and our camp host is happy – no more leaving ordinary keys with the customers.

We recently installed two keyless locks, and we love them. They work great and have eliminated the need to carry keys everywhere.
