Rekey vs. Replace: Choosing the Right Lock Update After a Move or Lost Key
Call Now to Get MatchedQuick Answer
Rekeying keeps your existing lock hardware and changes it to work with a new key — usually the faster, simpler option after a move-in or lost key. Replacement makes sense when the lock itself is worn, damaged, or you want different hardware or stronger security. Call +1 (833) 770-4413 to describe your situation, and we'll help connect you with a local provider who can recommend the right approach.
What Rekeying Actually Changes
Rekeying replaces the small internal pins inside a lock cylinder so it responds to a new key instead of the old one — the lock body, exterior hardware, and everything visible about the door stays exactly the same. Any old keys stop working the moment the pins are changed, which is the entire point.
When Rekeying Makes Sense
Moving into a new home or apartment is the most common trigger, since you have no way of knowing how many keys exist or who has them. Losing a key without knowing where it ended up is another — rekeying closes that gap without the cost of new hardware. It's also a reasonable step after a roommate or tenant moves out, or simply for peace of mind if you're unsure who might still have access.
When Replacement Is the Better Call
If the lock itself is visibly worn, damaged, or unreliable — sticking, hard to turn, not latching consistently — rekeying won't fix any of that, since it only changes what key works, not the mechanical condition of the lock. Replacement also makes sense if you want to upgrade to a higher security grade, add smart-lock features, or simply want hardware that matches the rest of your doors.
What Generally Differs Between the Two
Rekeying is typically the quicker visit, since the provider is working with hardware that's already installed and functioning. Replacement takes a bit more time because new hardware has to be selected, fitted, and installed — but it's also the only option that changes anything about the lock's condition, features, or security level. Ask the provider directly for their assessment and pricing once they've seen your specific locks.
If You're Considering a Bigger Change
Rekeying and replacement both assume you're sticking with a similar type of lock. If what you're really weighing is a move to something different entirely — a smart lock, or an access control system for a business or rental property — our security upgrade comparison guide walks through that decision instead.
Frequently Asked Questions
How does SkilledMob Locksmith matching work?
SkilledMob is a call-referral service, not a locksmith company. When you call, we ask a few quick questions about what's going on with your locks or keys, then help connect you with an independent local provider who handles that type of job, where service is available in your area.
How do I know what kind of locksmith service I need?
The right service usually comes down to what's happening — a lockout, a broken key, a malfunctioning lock, or wanting stronger security all point to different types of jobs. When you call, describe exactly what you're dealing with and we'll help match you with a provider suited to that specific situation.
Is rekeying available for every type of lock?
Most standard residential and commercial locks can be rekeyed, though some specialty or high-security locks may have restrictions — ask the provider about your specific lock when you call.
If I rekey now, can I upgrade to a smart lock later?
Yes — rekeying and upgrading later are independent decisions, so choosing to rekey today doesn't rule out a bigger upgrade down the road.
