Why Residential Lock Rekey After Move-In Is a Non-Negotiable First Step
When you receive keys at closing, those keys represent the final known set — but they are rarely the only set that has ever existed. Sellers routinely give copies to family members, property managers, cleaning crews, and even dog walkers over the years. A lock rekey addresses this by having a trained technician disassemble each lock cylinder and replace the internal pin tumblers so that every old key becomes permanently useless. Your new key is the only key that will ever work again. This is categorically different from simply changing your locks, because a rekey preserves your existing hardware while eliminating all prior access — making it faster, less disruptive, and a smarter use of your investment in quality deadbolts, mortise lock assemblies, and door knob locks already installed in the home.
Blythewood has grown steadily over the past decade, and a large share of its housing stock is resale homes that have passed through multiple owners. That history is exactly why our technicians emphasize move-in rekeying so strongly. A single service visit can cover every exterior entry point — front door, back door, garage entry, and any secondary access points — so you finish move-in day knowing your family is the only family with working keys to your home.
