You just got the keys to your new place on, say, Dunton Avenue or somewhere off Rand Road — congratulations. But before you unpack a single box, there's one question worth settling: who else might have a copy of your front door key? Previous owners, former tenants, a contractor who did work last spring — you have no way of knowing. That's why rekeying or replacing your locks is one of the smartest first moves any new Arlington Heights homeowner can make, and it's a decision our team helps people work through every single day.
The good news is that you don't necessarily need a brand-new lock to get brand-new security. This guide breaks down exactly what rekeying means, when a full lock replacement makes more sense, what factors shape the final cost, and how to figure out which path is right for your specific doors — including older mortise lock setups, modern smart locks, and everything in between.
## Rekey or Replace: What's Actually the Difference?
Rekeying a lock means a skilled locksmith disassembles the cylinder and swaps out the internal pins so that your existing hardware now responds only to a brand-new key. The lock body, the deadbolt, the strike plate — all of that stays exactly where it is. So how do you rekey a door lock? A trained technician removes the cylinder, reconfigures the pin stack to match a new key cut, reassembles everything, and tests it. The whole process usually takes just a few minutes per lock when done by an experienced professional. The result: every old key that once opened your door is now useless, and you control who gets the new one.
A full lock replacement, on the other hand, means removing the entire lockset — cylinder, housing, handles, and all — and installing new hardware. This makes sense when the existing lock is worn, damaged, an outdated mortise lock that no longer engages cleanly, or simply not the security grade you want on your home. Replacement takes longer and involves parts, which is one reason the final quote will differ from a straight rekey job. Neither option is universally better; the right answer depends on the condition and type of your current hardware.
## How Do You Rekey a Lock — And Can You Rekey Any Lock?
One of the most common questions we hear is: can you rekey any lock? The honest answer is almost, but not quite. The vast majority of standard pin-tumbler deadbolts and door knob locks — Schlage, Kwikset, and most other major hardware brands — can be rekeyed quickly and cleanly. A mortise lock, which you'll find on many older Arlington Heights homes and on most commercial storefronts along Campbell Street or Algonquin Road, can absolutely be rekeyed as well, though the cylinder design is different and requires a technician familiar with mortise lock systems specifically. Where things get more nuanced is with smart locks.
Can you rekey a smart lock? It depends on the model. Some smart locks have a physical key cylinder as a backup entry method, and that cylinder can be rekeyed just like a traditional one. Can you rekey a Yale smart lock, for example? Many Yale models do include a rekeyable cylinder, so yes — but the process varies by generation, and some require the original key to initiate it. Can you rekey a smart lock without the original key? In some cases a trained technician can still service the cylinder, but it requires additional steps and may not be possible on every model. If you're not sure what you have, call us before assuming — we'll tell you upfront what's feasible. Can you rekey a lock to match an existing key? Yes, this is a common request when homeowners want all their exterior doors to operate on a single key, and it's a straightforward service for a qualified locksmith.
## When a Full Lock Replacement Makes More Sense for Arlington Heights Homes
Rekeying is elegant when the lock itself is in good shape. But there are clear situations where replacing the hardware entirely is the smarter call. If the lock is visibly worn — the deadbolt drags, the cylinder is loose, or the door knob lock feels sloppy — rekeying a failing mechanism just gives you a new key to a lock that's already on its way out. Similarly, if you've moved into a home with an older mortise lock that's showing its age, upgrading to a modern mortise lock with a higher security rating gives you both fresh keying and better protection in one step.
Security upgrades are another reason to replace rather than rekey. Grade 1 deadbolts offer substantially more resistance to forced entry than Grade 3 hardware, and the physical difference in the bolt and strike plate matters. If your current locks are lightweight builder-grade hardware, a replacement is an investment in the door itself, not just the key control. Our team can assess what you have, explain the difference between your options in plain language, and give you an exact up-front price before touching anything — so there are no surprises on the invoice. If you're ready to talk through your specific doors right now, call (224) 494-2075 and we'll walk you through it.
## What Determines the Cost — and What to Expect in Arlington Heights
We don't list flat prices here because an honest quote depends on real variables that differ from job to job. The factors that shape what you'll pay include the type and brand of lock (a standard door knob lock costs differently to service than a high-security mortise lock), the number of locks you're having done, the time of day (our emergency locksmith availability around the clock means we respond at 2 a.m., and after-hours calls involve different logistics than a Tuesday afternoon appointment), and whether parts are needed. Travel distance within the Arlington Heights area also plays a role for mobile service calls.
What we commit to every time: you get a confirmed, exact price before any work begins. No hourly guessing, no surprise charges when the job is done. One question we hear often is 'What is the average call out fee for a locksmith?' — and the honest answer is that it varies by provider and by circumstance. What matters more than an average is knowing exactly what you'll pay before you say yes. That's the standard we hold ourselves to on every residential and commercial locksmith call across Arlington Heights.
## Smart Locks, Mortise Locks, and Commercial Properties: Broader Scenarios
New homeowners aren't the only ones asking these questions. If you manage a small business along Northwest Highway or own a rental property near Olympic Park, key control is a recurring challenge every time a tenant turns over or an employee leaves. Commercial locksmith work — rekeying office deadbolts, servicing mortise lock hardware on storefront doors, or upgrading to access-controlled systems — follows the same decision logic as residential work, just with higher traffic demands on the hardware. A commercial-grade mortise lock is built to handle hundreds of cycles a day in ways a residential lock isn't.
Smart lock questions come up constantly too. Can a locksmith reprogram my key fob? For vehicle smart keys and proximity fobs, yes — programming is a separate service from rekeying but one our mobile team handles regularly. Can a locksmith open my door if you're locked out? Absolutely — that's one of the core reasons a 24/7 emergency locksmith exists. Our technicians use professional, non-destructive methods to verify ownership and regain entry. And if the question in the back of your mind is 'How do I know if a locksmith is legitimate?' — look for a team that arrives in a marked vehicle, provides a written quote before starting, and asks for proof of ownership before opening any lock. That's standard practice for every call we take. If you ever need us in the middle of the night or on a holiday weekend, we're reachable at (224) 494-2075 — 24 hours a day, 7 days a week.

Frequently asked questions
How do you rekey a lock, and is it something I can do myself?+
Rekeying involves disassembling the lock cylinder and replacing the internal driver and key pins with a new set that matches a different key cut. Rekey kits exist for some popular lock brands, but getting the pin depths right requires precision — an incorrect pin combination can leave you with a lock that binds, sticks, or fails entirely. For a single lock on a quiet afternoon it's a manageable DIY project if you're mechanical and patient. For multiple locks, a mortise lock cylinder, or any smart lock, a trained locksmith will get it done correctly and quickly, and you'll have confidence the lock actually works as intended when they leave.
What is the crime rate in Arlington Heights, Illinois, and does it affect which lock I should choose?+
Arlington Heights consistently ranks as one of the safer communities in the Chicago suburbs — property crime rates here are well below state and national averages, and violent crime is rare. That's genuinely good news, but it doesn't mean lock quality doesn't matter. Opportunistic break-ins happen even in low-crime areas, and a worn deadbolt or a door knob lock with a flimsy strike plate is an invitation regardless of neighborhood statistics. The right lock choice is less about local crime rates and more about controlling who has key access to your home — which is exactly what rekeying or replacing addresses directly.
Can a locksmith open my door if I'm locked out, and will they damage the lock?+
Yes, gaining entry for verified owners is a core part of what an emergency locksmith does. A trained technician will ask for proof that you own or are authorized to access the property — a photo ID matching the address, a lease, or similar documentation — before beginning. Professional, non-destructive entry methods are used whenever possible, meaning your lock and door frame are left intact. In situations where the lock itself is damaged or picking isn't viable, the locksmith will discuss options with you before proceeding with anything that affects the hardware. You're always informed before any action is taken.
Can you rekey a smart lock without the original key, and what about reprogramming key fobs?+
It depends on the specific lock model. Some smart locks allow cylinder service without the original key through a disassembly process, while others have design constraints that make it difficult or impossible without the manufacturer's credentials. A skilled technician can assess your exact model and tell you on the spot what's feasible. Key fob reprogramming is a related but separate service — our mobile team handles transponder key programming and fob replacement for a wide range of vehicle makes, which is different from physical lock rekeying but equally common as a service call. Call (224) 494-2075 and describe what you have; we'll tell you exactly what's possible before you commit to anything.
