| Hardware Type in Kensington | Why Standard Retail Parts Misfire | Our Inspection Focus | Preferred Service Path |
|---|---|---|---|
| Older Residential Mortise Lock | Modern 2-1/8" tubular retail deadbolts do not fit rectangular mortise edge pockets. | Inspect edge faceplate dimensions, hub springs, and spindle play via photos. | Repair internal mortise case/springs, rekey mortise cylinder, or fit clean wrap plate. |
| Decorative Brass / Period Handleset | Thumbpiece shuttle fractures while upper deadbolt and exterior finish stay intact. | Check center-to-center bore spacing and internal tubular latch retraction. | Replace worn internal latch/spindle or rekey cylinder while retaining exterior trim. |
| Swollen Exterior Wood / Patio Door | Forcing the key bends brass blades and snaps tailpieces when frames swell. | Test bolt throw open vs. latched; inspect hinge mortises and strike lip. | Re-seat hinges with long framing screws and adjust strike clearance cleanly. |
| Historic-District Commercial Entry | Narrow street parking and older wood/aluminum storefronts need careful fitment. | Confirm street/loading parking spot and photograph both sides of lock body. | Match commercial cylinder cam, deadlatch backset, and smooth closer sweep. |

Many Kensington hardware failures start with 2 millimeters of strike-plate friction or a worn brass key copied too many times. Testing shear-line action, backset geometry, and frame clearance on-site in Montgomery County determines whether rekeying, adjustment, or Grade 1/2 replacement fits your door.
From Kwikset SmartKey and Yale touchscreens to Medeco commercial cylinders and Toyota/Volkswagen laser blades, we verify Kensington parts compatibility before cutting or programming.
