Why a Lock Rekey After Home Purchase Is Non-Negotiable
When a home sells, the locksmith industry rule of thumb is simple: treat every key in existence as compromised. Your seller may have been scrupulously careful, but prior tenants, in-home service workers, dog sitters, and extended family members could all hold copies. A lock rekey renders every one of those unknown keys permanently useless without replacing the hardware itself. The internal pins inside the cylinder are reconfigured to a brand-new cut, and only the fresh keys your technician hands you will work. It's a damage-free process that preserves the condition of your door and lock hardware — important when you're already managing closing costs and moving expenses.
This is especially relevant for Merrillville homeowners buying resale properties. Older neighborhoods like Ross Township and established subdivisions off US-30 often have homes that have changed hands multiple times. Each transfer is another opportunity for key copies to circulate. Even brand-new construction isn't immune — builder-grade lock sets commonly share keyways across multiple units during the construction phase. A thorough lock rekey service at move-in closes all of those gaps at once, giving you full control over who can enter your home from day one.
