Interconnected Door Lock Help

Interconnected door locks are available in a couple of different styles. You'll want to verify how your existing door is prepped before ordering to be sure you order the correct door hardware. To help, here is some basic infomation about two types of interconnected locks.

Standard Bore Door Prep

Emtek has several sideplates and many handlesets that are designed to fit the standard 5 1/2" center to center bore door prep. You can select from any styles and finishes, just be sure to add the interconnect option when adding the hardware to your shopping cart.

2 7/8" Center to Center Bore Door Prep

Less common, but still out there quite often is a 2 7/8" center to center bored door. There are a few locks that will fit this type of set up. The interconnect on these works similar to Emtek's where the mechanism is behind the decorative backplate so no additional door prep is necessary to install the interconnected lock.

Mortise Locks

Mortise locks require special preparation and while a little less common and somewhat more expensive, are very nice locks. Mortise locks don't use the standard tubular latch that most of us have in our homes. Instead they use a narrow box that slides into the edge of your door. If you door is already prepped with bore holes, you may not be able to convert to a mortise box. The mortise locks have a very solid, smooth operation which is nice on a higher traffic door. The mortise box is interconnected so that when you turn the knob or lever to open the door it also unlocks the deadbolt. You can also set the hardware to lock behind you when you leave (this locks the handle, not the deadbolt).
