I've replaced an exterior door on my house and the old deadbolt won't fit in the new door because the back set is different.
The deadbolt key is common to all my exterior doors, and I'd like to be able use the same key with the new door.
About The Old Lock
The lock may be original to the house which was constructed in 1989. The brand Lori is also associated with Ilco, Kaba, and US locks. The lock cylinder is a mortise style cylinder. The diameter of the notches is 1" and the diameter of the threads is about 1.14". The deadbolt assembly appears to be model 4512-05 S/C US5. I'm only able to find 2" backsets but I need 2-3/4".
The Keyway is KW1 and there are 5 pins.
How can I find a deadbolt that uses the same key as my other locks but fits in this door?
