Rekeying vs. Replacing Locks Between Tenants: What Landlords Need to Know

When tenants move out, deciding between rekeying and replacing locks comes down to security and cost. Rekeying changes internal pins so old keys don't work, perfect for standard cylinders. Full replacement is needed for worn or high-security systems. I usually assess lock condition first; a quick rekey saves money but only if the hardware is solid. Either way, never skip updating keys between tenants—it's a basic safety practice and often legally required.
