King Locksmith and Doors helps high schools in Maryland, DC, and Northern Virginia lock down, control who gets in, and keep every exit code-ready, from front office to field house.
Teachers should never step into a hallway to lock up. We install locks that secure the room from inside, instantly.
Open side doors invite trouble. Door alarms, closers, and access control alert staff when an entrance stays open too long.
Missing master keys put every room at risk. Restricted keyways and rekeying stop copies and restore control across your campus.
Barricade devices can block exits and break fire code. We fit lockdown hardware that keeps free egress and ADA access.
A high school is more than classrooms. Gyms, stadiums, auditoriums, labs, and offices each need their own level of protection. Some spaces stay open for night games and community events. Others hold costly tech, chemicals, or private records. King Locksmith and Doors designs a layered plan, so each area locks, unlocks, and alerts staff exactly when your schedule requires.
Secure vestibules, video intercoms, and electric strikes keep visitors at the front office until staff approve their entry.
Lockdown locksets and keyed storage protect students, lab chemicals, and computer rooms without slowing anyone's exit in emergencies.
Scheduled access control opens doors for games and practices, then locks them again automatically when evening events end.
High-security locks and safes guard student files, exam materials, and cash from ticket sales and weekend school fundraisers.
Safety and security must work together. A lock that traps students during a fire is not a solution. We follow NFPA 101, IBC, and ADA rules on every classroom door we touch.
Our locks engage from inside without opening the door, and they always release with one motion. You get real protection and a clean fire marshal inspection every time.
A broken lock or a door that will not latch is a safety gap. You cannot wait days for a fix. Our mobile technicians carry common commercial parts and respond fast across the entire DMV.
We secure the opening the same day whenever possible. Then we schedule lasting repairs around your bell schedule and testing days, so learning never stops.
Juggling a lock vendor, a door shop, and an access control company wastes time. Details fall through the cracks.
King Locksmith and Doors handles it all. We install doors, frames, locks, exit devices, card readers, and safes. One team means one plan, one point of contact, and hardware that works together.
In a high school, keys pass through many hands. When a master key goes missing, every room is exposed.
We design restricted master key systems with patented keyways that cannot be copied at a hardware store. We also help you track who holds each key and rekey fast when staff change.
School funds are tight, and every dollar must count. Not every door needs the most costly upgrade.
We start with a site walkthrough and rank risks by priority. Then we build a simple phased plan that fits your budget and supports state safety grant requests, like Maryland’s Safe Schools Fund.
