Locksmithing/Locksmithing-LORI Deadbolt Removal


    I purchased a house which has a LORI double-cylinder dead bolt on the rear door.  The previous owner did not provide a key.  There are no visible fasteners on eitehr cylinder and the faceplate does not seem to be removeable.  A friend who is learning locksmithing as a hobby was able to pick the lock so I could open the door.  I would like to know how to remove this lock so I can put matching locks keyed the same on my home.  Any assistance would be appreciated. Thanks,


** 1/6/2013 I've updated the link to the photo I originally posted. **

Remove the plate from the edge of the door where the bolt extends from.

Insert a small allen wrench (sorry I can't remember the size) between the bolt and the edge of the door.  There is a set screw holding the key cylinder and once you back the set screw off a bit, you can unscrew the key cylinder from the door.

Open the following link in a new browser.  It's hard to describe in words what to do so here's a pictures:

Once you have the mortise cylinders removed, you can take them to a locksmith to have them rekeyed.  I wouldn't suggest getting the whole thing replaced since the lock you have is considered a commercial lock, and commercial locks last longer than residential locks due to their construction, plus they don't cause as many problems as residential locks.

I hope this helps.

I do not answer Safe or automotive questions. Period. I am knowledgeable in almost every area of Locksmithing. This includes locks, keys, lost keys, residential and commercial lockouts, rekeying, masterkeying, high security locks, access control, electric locks, security cameras and home safety. I have been running an online business since 2004 where I sell all types of lock and security hardware to everyone from apartment renters to business owners to the US government. Before that I started a locksmith service in 1999. I deal with many types of security equipment including high security safe locks, heavy duty padlocks, exit devices, biometric readers, electric strikes, magnetic locks, full surface hinges and I only sell what I personally stand behind 100%. The online business has given me a more in-depth look at the locksmithing industry, helping me to learn more about each and every product that I offer, as well as products I don't have but end up finding for customers to solve any issues they have with security or door hardware.

Please don't submit any automotive or safe questions as these aren't areas that I can help in.
