Rekeying Locks vs. Replacing: How to Choose the Right Option for Your Home or Business

Rekeying locks is one of the most practical security decisions a homeowner or business owner can make, but knowing whether to rekey or fully replace it is not always obvious. This guide breaks down both options so you can make a confident, cost-smart choice for your Scottsdale, AZ property.

Rekeying locks means a locksmith changes the internal pins of your existing lock cylinder so old keys no longer work. The hardware stays in place. Lock replacement means the entire assembly is removed and a new one is installed. Rekeying is typically faster and more affordable.

Rekeying locks typically costs between $15 and $40 per lock, takes around 10 to 20 minutes to complete, and allows you to keep your existing hardware. Full lock replacement generally runs between $75 and $200 or more per lock, takes 30 to 60 minutes, and requires removing the old hardware entirely. Prices vary depending on lock brand, quantity, and service call fees.

Rekeying works best when your lock hardware is in solid condition. Common situations where a rekey makes sense include:

▸ You just moved into a new home or rental and do not know who has copies of the existing keys.

▸ A tenant moved out and you cannot account for all key copies.

▸ An employee was terminated or left your business.

▸ A key was lost or stolen, but the lock shows no damage.

Professional lock rekeying in Scottsdale, AZ, restores full access control without replacing every lock on the property. For businesses managing multiple doors or tenant turnover, explore commercial re-key services as a streamlined option.

Full replacement is often the smarter investment when the lock itself is the problem. Consider replacing if any of these apply:

▸ The lock is visibly worn, corroded, or difficult to turn.

▸ The cylinder was drilled or damaged during a break-in attempt.

▸ You want to upgrade to a smart lock or keypad entry system.

▸ The lock brand is outdated and no longer meets modern security standards.

Scottsdale's extreme summer heat deserves special mention. Prolonged exposure above 110 degrees Fahrenheit causes door frames to expand and contract, placing extra stress on lock cylinders. If your locks are binding or feel gritty, the mechanism may be worn beyond what rekeying can fix. Neighborhoods from McCormick Ranch to Grayhawk all contend with the same desert wear.

▸ The key requires force or jiggling to turn.

▸ The deadbolt does not seat fully into the strike plate.

▸ The lock is over 10 to 15 years old with no prior maintenance.

▸ The exterior finish is cracked, pitted, or corroding.

These signs point to a lock that has physically degraded and would benefit from full replacement rather than an internal pin change.
