King Locksmith and Doors has served Maryland for over 25 years, and our mobile units cover every street from Cobb Island Road to Fisherman’s Field, plus the mainland along MD-257 through Newburg and Rock Point. Whether you need a lockout resolved tonight, a rental rekeyed before Friday check-in, or corroded waterfront hardware replaced before it fails, one call to (240) 345-1455 gets a licensed, in-house technician on the way.
Don't wait on a dealership or a locksmith dispatched from Waldorf. King Locksmith and Doors sends licensed Maryland technicians straight to Cobb Island 24 hours a day with upfront pricing and everything needed to finish the job in one visit.
Cobb Island residents have limited options this far down the peninsula, and too many “local” listings are call centers that subcontract the job to whoever’s available. King Locksmith and Doors is different: every technician is our own employee, licensed in Maryland, background-checked, and equipped to handle residential, commercial, automotive, and safe work in a single trip.
King Locksmith and Doors is a licensed, bonded, and insured Maryland locksmith company. Our technicians complete ongoing training on high-security, electronic, and automotive lock systems, so the person who arrives at your Cobb Island door is qualified for the job, not learning on it.
We are authorized supplier and installer for most door hardware brands trusted in hospitals, schools, and government buildings across Maryland. For Cobb Island homes and businesses exposed to salt air and storm weather, we recommend and install Corbin Russwin, Sargent, Medeco, and Best hardware rated for corrosion resistance and long-term durability.

From the bridge over Neale Sound to Cobb Island Station at the southern tip, and across the mainland along Cobb Island Road and Rock Point Road, our locksmiths cover the entire island and the surrounding Cobb Neck peninsula.
Cobb Island homes are mostly cottages and waterfront houses, many built decades ago with original hardware that salt and humidity have quietly worn down.
Our residential locksmiths repair and replace sticking deadbolts, rekey every entry to a single key, extract broken keys from corroded cylinders, and cut duplicates on site. We also install screen door and slider locks, garage locks, and mailbox locks, and we recommend weather-rated hardware that holds up on the water.
A single failed lock can shut down a restaurant or leave a marina office open overnight. Get commercial-grade hardware, master keys, and emergency repair from a licensed Maryland locksmith who serves the island.
Keys dropped off the pier, fobs left in the boat, or a car locked with the engine running at the crab house happen more often than you’d think.
Our automotive locksmiths come to you anywhere on Cobb Island or the Cobb Neck with the equipment to cut and program transponder keys, replace key fobs, unlock any make or model without damage, and repair worn ignitions on the spot. It’s faster and far cheaper than a tow to a dealership in Waldorf.

Salt air, humidity, and storm exposure from Neale Sound and the Potomac corrode brass and zinc lock components, leading to seized cylinders, sticky deadbolts, and keys that break off inside. We recommend and install marine-grade, weather-rated hardware from brands like Medeco, Schlage, and Corbin Russwin that resists corrosion and lasts years longer on the water.
