LOCKER will protect your Access files hiding all that can be hidden, and blocking all that can be blocked. It also converts your .accdb file into an .accde to protect your code. Not a bullet proof protection, of course (we're talking about Access!), but it gives you the top protection that Access allows. You can create different "tasks" to store your locking options, so if you need to re-lock a file after you modified the source, you can do it in two clicks only.
