Lock Rekey Service in Rockville, MD

Why most Rockville homeowners rekey instead of replacing locks

Rekeying is the single most cost-effective security upgrade most Rockville homeowners ever make. The job swaps out the internal pins inside your existing cylinder so the old keys stop working, while the hardware itself stays on the door. You keep the deadbolt and knobset you already have (assuming they are in good condition), and you walk away with a brand-new key your previous owner, previous tenant, contractor, dog-walker, or ex-roommate cannot use. The math is simple: rekeying a typical four-door Rockville home costs a fraction of replacing the same four locks with new hardware.

The four Rockville scenarios where rekeying is the right call

We handle hundreds of Rockville rekeys each year and they almost always fall into one of four buckets. First, post-closing rekeys: new homeowners in Twinbrook, Fallsgrove, King Farm, and Rockville Town Center call us within a week of move-in because they have no idea who else holds keys to the house — contractors, the previous owner's family, the realtor's lockbox crew. Second, lost-key rekeys: you misplaced a key, can not find it, and would rather kill the old key than gamble. Third, roommate or relationship rekeys: someone moved out and you want their key dead. Fourth, keyed-alike conversions: you are tired of carrying three different keys for front, back, and garage entry, so we re-pin every cylinder to share one key.

What a Rockville rekey appointment actually looks like

We arrive in an unmarked vehicle, confirm your identity, and walk the home with you to identify every cylinder you want rekeyed. Most Rockville single-family homes have four to six: front deadbolt, front knob (if separate), back door deadbolt, garage entry deadbolt, side or basement walkout, and sometimes a patio slider lock. We remove each cylinder, change the pin combination on a portable bench in your driveway, cut a fresh set of keys to match, reinstall the cylinder, and test every door with you before we leave. The whole job is typically 30-60 minutes for a four-door home, with no door removal and no debris.
