El Cajon has thousands of apartment and condo units along Broadway, Madison Avenue, Mollison Avenue and Second Street, many built in the 1960s-to-1980s with knob-and-deadbolt sets that have been rekeyed dozens of times. Single-family streets in Fletcher Hills, Bostonia and off Chase Avenue are mostly 1950s-to-1970s homes, often with the original Kwikset hardware. The heat is a factor: summer afternoons that often top 90 degrees expand doors and make marginal deadbolts bind, which a rekey and strike adjustment usually fixes. Storefronts along Main Street and Magnolia Avenue mean a steady run of commercial rekeys as well.

El Cajon questions
I own a small apartment building in El Cajon. Can my key open every unit while tenants only open their own?
Yes. That is a small master key system, and it is standard for El Cajon rentals. Each tenant gets a key to their unit only, you carry one master, and we can rekey a single unit at turnover without disturbing the rest.
My deadbolt binds every summer afternoon. Do I need a new lock?
Usually not. Heat swells wood doors and shifts the bolt against the strike plate. We adjust the strike, deepen the bolt pocket if needed and service the cylinder. If the lock itself is worn, we will say so and quote a replacement.
Do you rekey storefront doors on Main Street and Magnolia?
Yes. Aluminum storefront doors use a different cylinder type than a house, and we service them. We can also key a back door and storefront alike or set up a master for staff, usually in a single visit before or after business hours.
Timing and cost in El Cajon. Most El Cajon appointments are same day during business hours (Mon–Fri 7am–8pm · Sat–Sun 8am–6pm), with an arrival window and a firm price given up front.
