Rekey vs Replace Locks in Garland TX - Which is Right for You?

Fast Decision: Rekey or Replace?

Choose rekeying when the lock works smoothly and the main problem is access control: old owners, tenants, contractors, roommates, or lost keys. Choose replacement when the lock is worn, damaged, unreliable, mismatched, or missing the feature you want, such as a keypad, smart lock, better finish, or higher-security hardware.

• Rekey: working hardware, old keys need to stop working, same look stays on the door
• Replace: worn or damaged hardware, security upgrade, smart-lock/keypad upgrade, new finish or function
• Mix both: replace the bad lock and rekey serviceable locks to match when compatible

What Rekeying Does and Does Not Do

Rekeying changes the internal pin configuration of a serviceable lock so the previous key should no longer operate that rekeyed cylinder when the work is done correctly. It keeps the same hardware, finish, and function. GLC's published range is $19-$110+ per lock, and current service data lists a standard residential rekey at about 15-30 minutes per lock depending on the lock and condition.

• Cost: $19-$110+ per lock
• Typical 3-lock Garland home: $75-$150+ total
• Keeps existing hardware and finish
• Does not repair worn hardware, add a keypad, or improve the lock grade

What Replacing Locks Solves

Replacing means installing new deadbolts, knobs, levers, or smart hardware. It is the better choice when the lock is stiff, damaged, unreliable, mismatched, or not the security level or function you want. GLC's published replacement range is $65-$315+ per lock, including hardware and labor, with the final quote tied to the selected lock and door condition.

• Cost: $65-$315+ per lock including hardware and labor
• New hardware, keys, finish, or function
• Best fit for worn locks, damaged locks, smart-lock upgrades, or security-grade upgrades

When to Rekey

Rekeying is the right move when your locks are in good condition and you need old keys to stop working. Common examples include buying a house, ending a lease, a roommate moving out, a contractor key you cannot account for, or a lost key. For move-in planning, see why change locks after moving into a new house.

When to Replace

Replace your locks if they are worn, stiff, damaged, mismatched, or not suited to the door's job. Replacement is also the path for a smart lock, keypad, new finish, or a security-grade upgrade. Rekeying cannot add electronics, repair broken hardware, or turn a low-grade lock into higher-grade hardware; it only changes key access on a serviceable lock.

Can You Mix Rekeying and Replacing on the Same Visit?

Yes, when the locks and keyways are compatible. Example scope: replace one worn front deadbolt, then rekey the serviceable back door and garage-entry locks to match the new key. GLC quotes each lock separately so you can see which openings are rekeyed, which are replaced, and which price range applies. For every published range, see the 2026 locksmith cost guide.
