DIY or hire

Angi says rekeying is a DIY job in a pinch, but you need the exact rekey kit for your lock’s brand, and buying the wrong one is the usual mistake.4 Kits cost $10 to $25 each. If you have many locks, a kit set is cheaper than a locksmith’s per-lock fee, and a locksmith is faster if you are locked out. Home Depot’s door lock category lists locks by brand so you can check which kit fits yours. Renters should ask the landlord before rekeying.1
