Explain whether your Lanham lock binds when latched, lost its last key, or rejected an electronic PIN/fob so our van brings matching parts.
Before unlocking or repinning at your Lanham site, we check ID/registration and agree on the full scope and cost.
Every rekeyed plug, adjusted strike box, exit bar, or vehicle key in Lanham is cycled repeatedly with you present.
Many Lanham 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 Prince George's 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 Lanham parts compatibility before cutting or programming.
