This installation was for a new owner of an older home. The customer wanted all locks on the house keyed alike to a key that was not compatible to the old Yale on the basement door. The lock was an old Yale 197-1/4 drop bolt that was no longer lining up with the jamb anyway, so it just had to go.

The deadbolt being removed was also of an extinct type, it had an angled body that was cut into the edge of the door, not just mounted to the inner surface. So it was going to need a MAG repair sleeve, which would go with an Arrow E62 double cylinder deadbolt and a repair strike for the jamb.

First the old lock body and cylinder are removed, which is sometimes quite difficult on an older lock with one way anti theft screws installed. Sometimes the Dremel tool gets used for this. Fortunately, I was able to get these out without too much trouble.

Next, I mark the area to be bored out for the new lock and use a jig as a guide for the 2-1/8 inch hole saw. The jig is necessary since there is already a hole in the door, leaving no place for the pilot bit in the hole saw to do the guiding.

   After boring for the edge as well, I close the door and mark the exact position on the jamb where the 1 inch deadlock bolt will need to go. Then I slide the MAG sleeve over the door with the bolt portion of the lock already screwed to the sleeve. Using the 2 large mounting bolts, the outer body of the deadbolt gets mounted to the door, then the inner half gets attached with the 2 concealed screws to the outer half.

    Satisfied that the MAG sleeve and the deadbolt are lined up correctly, I can drill and install the four screws to fasten the MAG sleeve to the door

    This is a good sturdy lock installation, and the most economical way to keep this door secure and usable for years to come. The only thing left for the customer to do would be to worry about the paint and trim repair where the old installations strike was removed, but in this non visible basement area the customer is unlikely to go thru the expense and trouble.
