Homeowners don't know how to securely rekey locks after moving into a new house

New homeowners face uncertainty about rekeying their locks—they don't know if they should do it themselves, hire a locksmith, or replace locks entirely. This creates security anxiety since previous owners or contractors may have copies of keys. Current solutions are fragmented: DIY options are confusing and risky, locksmiths are expensive and hard to vet, and homeowners lack clear guidance on which approach is safest and most cost-effective.
