So you’ve been asking yourself, Can I Rekey My Own Locks? It’s a fair question — and honestly, a smart one to ask. Whether a tenant just moved out in Gilbert, a relationship ended, or you bought a home near Arcadia in Phoenix and have no idea who still has a key, that uneasy feeling is your instincts talking. Listen to them. I’m Josh, and after ten years running service calls across Maricopa County, I’ve seen DIY rekeying done well and done in ways that left doors genuinely less secure. Let me give you the straight answer.
What DIY Lock Rekeying Actually Gets Right
Rekeying kits — mostly designed for Kwikset and some Schlage cylinders — have genuinely improved. A motivated homeowner with patience, the right kit, and a working lock can swap the driver pins and springs to render old keys useless. For a single, simple deadbolt in good condition, DIY rekeying can work. The rekey kit pros cons breakdown does favor the homeowner on pure cost: a kit runs roughly $15–$30 at a hardware store, versus a professional service call.
If you’re mechanically inclined and your lock is a standard residential Kwikset on a Chandler or Tempe track home, you might pull it off without a hitch. That’s the honest truth.
Where DIY Rekeying Goes Wrong — Fast
Here’s where things unravel. Most homes have multiple locks — front door, back door, side gate, interior deadbolts. Rekeying them to match, correctly, without a professional pinning tray and the right key gauge, is where small errors compound. Drop a spring inside the cylinder, reassemble it wrong, and you may not notice until the lock fails at 11 p.m. on a Tuesday. I’ve taken service calls in North Scottsdale and Paradise Valley where a homeowner tried a kit on a high-security Medeco or Mul-T-Lock cylinder — locks that require completely different tooling and factory-pinned key blanks. Those situations always cost more to fix than a professional visit would have cost upfront.
- Wrong kit for the brand: Schlage and Kwikset are NOT interchangeable — pins are different sizes.
- Worn or damaged cylinders: If the lock is already stiff or sticky, rekeying it doesn’t fix the underlying wear.
- High-security locks: Medeco, Abloy, and similar locks require proprietary tools — no consumer kit touches them.
- Multi-lock keying: Getting five locks to accept one key without professional gauging is genuinely difficult.
- Smart and keypad locks: If you’re considering an upgrade, explore embracing keyless door locks — rekeying isn’t even part of the equation.
Real security doesn’t come from saving $40 on a service call. It comes from knowing the job was done right and that your family is actually protected.
Rekeying vs Hiring a Locksmith: The Real Comparison
When you factor in your time, the cost of a kit, and the very real risk of a misassembled lock, the math shifts. A professional rekey service in the Phoenix area typically runs $20–$30 per lock for labor when bundled, with a service call fee on top. For most homes — say three or four exterior locks — you’re looking at a reasonable investment for guaranteed results, all locks keyed alike, and a professional eye on the hardware condition while we’re there. Our professional rekeying service covers exactly this scenario.
We also check for signs of forced entry, worn strikes, and misaligned doors — things a kit sitting on your kitchen table can’t do. If you’re a new homeowner near Camelback Mountain or just took over a rental in Mesa, that walkthrough matters. Our broader residential locksmith services include exactly that kind of complete security review.
When You Should Absolutely Call a Professional
Some situations don’t have room for a learning curve. Call us when:
- An ex-partner, former tenant, or terminated employee still has a key — urgency is real here.
- You’re rekeying more than two locks and want them keyed alike.
- Your locks are branded Schlage B-series, Medeco, or any commercial-grade hardware.
- You’re in a property near Old Town Scottsdale or a HOA community with specific hardware requirements.
- You want a professional to confirm your door frame and strike plate are actually holding up — because a perfectly rekeyed lock on a weak frame is still a security gap. The Library of Congress home security resource guide reinforces that physical door integrity matters as much as lock quality.
