What Is Lock Rekeying?
Lock rekeying is the process of changing the internal pin configuration of your existing lock so that old keys no longer work and new keys are required to operate it. The lock hardware itself — the deadbolt, knob, or lever — stays in place on your door. Only the pins inside the cylinder are changed. This makes rekeying significantly faster and more affordable than full lock replacement while achieving the same result: old keys become useless and only your new keys work. Rekeying is one of the most common residential locksmith services we provide, and it's the #1 recommendation for homeowners who have just moved into a new property.
When Should You Rekey Your Locks?
We recommend rekeying in these situations: when you buy or move into a new home (you don't know who has copies of the old keys), after losing a key, after a roommate or tenant moves out, after a relationship ends and an ex has a key, when you want all your locks to work with one key (keyed-alike service), after a contractor or service worker had temporary key access, and after any situation where you're unsure who might have a copy of your key. Rekeying gives you peace of mind by ensuring that only you and the people you choose have working keys to your property.
Rekeying vs. Lock Replacement
Choose rekeying when your locks are in good working condition and you simply want new keys. Choose lock replacement when the hardware is damaged, outdated, or you want to upgrade to a higher security grade or different style. Rekeying costs $25-50 per lock; replacement costs $100-300 per lock. Our technician evaluates your hardware and recommends the most cost-effective option.
Keyed-Alike Service
Tired of carrying a different key for every door? We can rekey all your locks to operate with a single key — front door, back door, garage entry, side gate, and more. This is one of our most popular add-on services during a move-in rekey. One key for everything, without replacing any hardware.
Frequently Asked Questions
How much does lock rekeying cost?
Lock rekeying typically costs $25-50 per lock cylinder. Most homes have 3-5 exterior locks, putting a full-house rekey at $75-250. Multi-lock discounts are available. High-security and smart lock cylinders may cost more. We provide exact pricing before any work begins.
How long does rekeying take?
Rekeying a single lock takes 5-10 minutes. A full-house rekey of 3-5 locks is typically completed in 30-60 minutes. Our technician comes to your home with all necessary tools and pins — no need to remove locks and bring them to a shop.
Can you rekey smart locks?
Most smart locks with a physical key cylinder can be rekeyed. Fully keyless smart locks that have no physical key option do not need rekeying — you simply change the access codes. We can advise on the best approach for your specific smart lock model.
Is rekeying as secure as changing the lock?
Yes. Rekeying changes the internal pin configuration so old keys cannot operate the lock. The security level of the rekeyed lock is identical to a new lock of the same grade and type. The only reason to replace rather than rekey is if the hardware is damaged or you want to upgrade to a higher security grade.
