Q:Would this lock work to replace an old skeleton key and doorknob lock? Our entry door is an antique skeleton key and I don't know what will work to replace it with a more secure lock without damaging the door

Answer This Question

A:  Hi - Most skeleton mortise locks were used for interior doors that typically have a different setup than the exterior doors. Be sure to measure the cavity in the door to make sure the internal mechanism can be inserted into the door, the measurements of this are 3-5/8 in. x 5-1/2 in. x 1 in. Thanks!

    Answer This Question

    A:  Hi DeeDee - unfortunately this lock is compatible with doors 1-3/8" to 2". If you need a lock for an interior door, be sure to checkout interior mortise listings as the locks tend to be slightly smaller for interior doors. Thanks!

        Customer No Service!
        I purchased this mortise entry door handle online and picked it iup at the Pilaski, TN Home Depot store.I had my contractor oinstall it and it worked less than one year. One day I tried to enter my home through the door with this mortise handle and the handle moved but when I pulled on the door nothing happened. I had to use a metal putty knife to move the latch so I could open the door. There is a 2 year warranty so I called the number listed several times. Every time I called I got an answering machine so I left messages. NO RESPONSE! I also emailed the company and again, I NEVER GOT A RESPONSE! I then went to the store and had the store manager call the company. He was able to get the warranty manager who said he would send replacement parts. Two weeks and NO PARTS!I fault both Premier and Home Depot because products are being sold with no backing by the manufacturer or Home Depot .

          Beautiful! Love that it is a more subdued brass color rather than bright.
