What options do I have for replacing this lock? (commercial)

[Kevin Richard]

So my wife's business has a back door with a failing lock and we also have a need to give access to many different people.

We have a digital deadbolt on our house and we love it.  This would work great for this situation as we could change the code when we needed to as well as have different codes for perm employees.

Is it possible to just drop one of these on here, is there some other option or do I just need to replace it with exactly what we have and go with a real estate style key lock box mounted on the wall?

Sorry, they are all sideways, send me your chiropractor bill. ;)

Thanks,
Kevin
