Yale locks have been specially designed for ease of installation so that the average do-it-yourselfer can approach lock installation with ease.
When installing a handleset or an entry lockset and a deadbolt on the same door take the time to align the locks so that the deadbolt locks freely when the door is shut normally.
All Yale products come with detailed installation instructions.
NOTE: Doors with pre-drilled holes contribute to ease-of-installation. If a door is not pre-drilled, it may be prudent to have a qualified vendor or installer drill and mortise the door for you.
