How to Save Money When Changing Locks: A Locksmith’s Guide to Rekey vs Lock Change
Most homeowners search for a “locksmith near me” to change their locks when they want different keys than the ones they have now. In many cases you don’t need new hardware. A locksmith rekey changes the internal lock configuration so only the new key works. That is why rekeying is usually the cheapest locksmith solution and the first step to securing access to your home.
Rekey vs lock change — 30-second answer
Rekey = new keys, same lock body. A locksmith changes the internal lock configuration so only the new key works.
Lock change = new cylinder or a full new lock. Choose this for worn hardware, visible damage, or a planned upgrade.
Why rekeying saves money
Lock cylinder removed for rekeying—a lower-cost option than a full lock change.
You pay for labor and small parts, not full lock sets.
One visit can key-alike multiple doors to one house key when locks are compatible.
Less drilling and adjustment means faster service and lower total cost.
Moving in? Rekey all exterior doors on day one
Prior owners, tenants, cleaners, contractors, or sitters may still hold copies. Rekey every exterior door when you move in. We serve all Arlington and can put front, rear, side, and garage-to-house doors on the same new key where compatible.
Keyed-alike convenience and compatibility
A locksmith can set multiple locks to one key if they share a compatible keyway. Compatibility depends on:
Brand/keyway families: Schlage and Kwikset use different keyways. Other brands and sub-brands may be compatible or not depending on the exact keyway.
How to spot likely compatibility: if one key inserts smoothly into another lock’s keyway (never force it), the cylinders often share a family and may be keyed alike. It is not a 100% guarantee; a pro confirms by checking keyway codes and cylinder specs.
When locks are usually not compatible to key-alike
Different brands with different keyways (e.g., Schlage vs Kwikset).
Different keyway cuts within a brand that do not match.
When a lock change makes more sense
When a lock change makes sense: replace worn or damaged hardware or upgrade security.
Wear or damage: gritty turns, plug wobble, bent latches, or tamper marks.
Upgrades: stronger deadbolt, new finish, or adding a keypad/smart deadbolt with key override.
Standardization: replacing a few outliers to move everything to one brand, then rekeying the set to one key.
Quick homeowner checklist before you book
List each exterior door to include.
Note lock brand stamped on the keys or trim (e.g., Schlage or Kwikset).
Choose a plan: one key for all, or keep shed/garage separate.
If any door drags or sticks, request a strike/hinge adjustment during the visit.
