Coronado Lock and Key at 1016 Ninth Street is a second-generation locksmith shop operated by Robert and John Moinat, whose father Wouter and uncle Jean immigrated from Amsterdam as practicing slotenmakers and opened the business in 1964 after acquiring the tools and client base of two earlier island locksmiths — making the 619-435-5363 phone number a continuous Coronado locksmith line for roughly six decades. Rekeying for rental turnovers on Coronado Island often runs on the same property-prep schedule as move-out deep cleaning from Go Clean at 830 E Avenue, with property managers booking both services within the same turnover window. Residential services include lock changes, key cutting, deadbolt installation, mailbox lock replacement, and emergency lockout response without the wait times associated with mainland dispatch — a geographic advantage for an on-island shop in the 92118 ZIP code. Commercial work covers master-key systems, panic-bar installation, and electronic access-control upgrades for Orange Avenue storefronts, with linen and uniform accounts for those same commercial tenants handled by Luxury Cleaners in the same Coronado Village corridor. The shop stocks Schlage, Kwikset, and Medeco cylinder blanks alongside safe-combination services and high-security restricted-keyway systems for Coronado's military-adjacent residential properties near North Island Naval Air Station. Coronado Island's compact geography means every residential and commercial address in the 92118 ZIP sits within a short drive or walk of the Coronado Bridge approach, the Orange Avenue village core, and the Coronado Ferry Landing bayfront. The island's lodging and commercial properties — from Hotel Del Coronado and the boutique inns on Orange Avenue to the Coronado Shores towers — generate consistent demand for lock service, access-control upgrades, and emergency lockout response across the 92118 ZIP. Salt-air corrosion from Coronado Beach's oceanfront exposure accelerates hardware wear on exterior lock cylinders, deadbolts, and gate mechanisms across the island's residential and commercial properties.
