Rekeying vs Replacing Locks After Buying a Home

When you buy a home, deciding between rekeying and replacing locks comes down to cost and condition. Rekeying is cheaper and keeps your existing hardware, while replacing locks lets you upgrade security or match your style. I'd rekey if the locks are sturdy, but swap them if they're worn or you want keypad entry.
