Same-Day Service on the Main Line, Chester and Delaware counties.
If you just moved into a home in Wayne, lost a key, or had a roommate situation change, your locks need attention today. Lock rekeying is the fastest and most affordable way to regain full control of who can access your property.
At Mline Locksmith, we service homes and businesses throughout Devon, Wayne, Berwyn, and the entire Main Line corridor, seven days a week from 7 AM to 11 PM.
Call us at (267) 609-9459 and we can be at your door in as little as 5 to 10 minutes.
Every pin tumbler lock contains a series of small metal pins inside the cylinder. When you insert the correct key, those pins align at a precise height and the cylinder rotates. Rekeying means we disassemble the cylinder, swap out those pins for a new set, and cut a fresh key to match. Your existing hardware stays exactly where it is. The old key simply stops working.
We rekey deadbolts, knob locks, lever handles, and mortise cylinders. We work with all major brands, including Kwikset, Schlage, Medeco, Yale, Mul-T-Lock, and Baldwin. Whether you have a classic stone colonial off Conestoga Road or a newer townhome in Chesterbrook, we handle the job on-site without removing your door hardware.
The process typically takes 10 to 20 minutes per lock. For most Main Line homes with three to five exterior doors, we complete the entire job in under an hour.
Rekeying is not just for emergencies. These are the most common situations where it makes clear practical sense.
If you just closed on a property in Wayne’s Downtown Historic District or anywhere along Lancaster Avenue, you have no way of knowing how many keys exist from the previous owner. Real estate agents, contractors, and prior tenants may all have copies. Rekeying immediately after closing puts you in control from day one.
It takes only 30 minutes for someone to make as many copies of your key as they want, and a “do not copy” warning rarely stops them. If a key is missing, rekeying is faster and cheaper than wondering whether it turns up in the wrong hands. Our same-day service means you are not waiting overnight on this.
A roommate moving out, the end of a relationship, or a family member who should no longer have access are all valid reasons to rekey. You deserve to feel completely secure in your own home.
For business owners and landlords throughout Wayne, Berwyn, and Paoli, staff turnover is a routine trigger. Periodic rekeying ensures that only current, authorized personnel hold working keys to your inventory, files, or office space.
FBI crime statistics indicate that 73.2% of burglary offenses are committed in residential properties, and roughly 55.7% of residential break-ins involve forced entry. If someone tried your door, your cylinder may have been damaged or manipulated. We inspect the hardware first and advise you honestly on whether rekeying or replacement is the right call.
If your home or office uses several different keys for different locks, we can often rekey every cylinder to operate on a single key. Fewer keys on your ring means fewer opportunities for one to go missing. Check our master key systems service.
Rekeying saves 50 to 70 percent compared to full lock replacement when your hardware is in good condition. Lock replacement costs around $315 on average, while rekeying a typical three-door house ranges from $150 to $250. If your deadbolts function smoothly, show no signs of wear, and are not visibly damaged, rekeying is almost always the smarter financial decision.
Replacement makes sense when the lock mechanism is worn out, the door frame or strike plate has damage from forced entry, or you want to upgrade to a high-security cylinder like Medeco or Mul-T-Lock. We also recommend replacement when a customer wants to convert to a smart lock or keypad entry system. Most residential locksmiths agree the average lock’s lifespan is about seven years, so if your hardware is aging, that conversation is worth having.
We never push for replacement when rekeying solves the problem. You get an honest assessment before any work begins. Learn more about our lock installation options if an upgrade is what you need.
There are no surprises with how we work. Here is exactly what happens when you call us for lock rekeying in Devon or anywhere on the Main Line.
You call (267) 609-9459 and describe what you need. We give you a clear price range before we dispatch. A licensed, insured technician heads to your location from our Devon base. Response time is typically 5 to 10 minutes for addresses in Wayne, Radnor, Strafford, and St. Davids.
On arrival, we inspect each lock for wear, damage, or tampering. We disassemble the cylinder, replace the key pins with the correct new driver pins, and cut fresh keys on-site. Every lock gets tested before we consider the job complete. We also do a quick post-service check to confirm smooth operation and proper door alignment.
No tools are left behind. No cosmetic damage to your door or frame. And every rekeying job includes a 1-year warranty on our labor.
We serve two distinct customer groups, and the approach differs for each.
For residential customers, the most common scenarios are new homeownership, tenant turnover in rental units, and post-lockout security reviews. We work in historic estates throughout Radnor Township, apartment units near Villanova University, rowhouses in Ardmore, and single-family homes across Tredyffrin Township and Chester County. If you live on the Main Line and need rekeying in Devon, PA 19333 or the surrounding zip codes, we cover your area.
For commercial customers, the stakes involve access control and liability. Office suites in Wayne and King of Prussia, retail spaces near Devon Yard, and storage facilities along Route 202 all benefit from scheduled rekeying after employee changes. We also set up master key systems for property managers who oversee multiple units, giving tiered access without duplicating keys across every tenant.
Landlords managing rental properties in Bryn Mawr, Haverford, and Wynnewood rely on us for between-tenant rekeying. It is a simple, affordable step that protects both your investment and your incoming tenant.
The average cost to rekey a lock in 2025 ranges from $50 to $150 per lock, depending on lock type, service fees, and location. A typical locksmith charges an average of $18 per keyhole to rekey, and $25 when additional work is required, such as decoding a lock without the original key or working with an electronic cylinder.
For a standard Main Line home with three exterior doors, the total typically falls between $150 and $250. In 2024, average service call fees ran $94, with labor charges of $104 during regular hours and $151 after hours. We are transparent about every component of your quote before we begin.
After-hours calls between 7 PM and 11 PM may carry a higher labor rate. We tell you that upfront. No technician starts work until you agree to the price.

Yes, in most cases. If the original key is lost or unavailable, a skilled locksmith can pick or decode the cylinder first, then proceed with rekeying. This step adds a small amount to the total cost, but it is straightforward work for an experienced technician.
We handle this regularly for new homeowners in Wayne 19087 who receive no keys at closing, and for tenants who inherit a rental unit with an incomplete key set. Call us and we will walk you through the specifics before anyone shows up at your door.
Security professionals generally recommend rekeying your home every three years as a baseline. If your household sees frequent visitors, contractors, or housekeepers, consider doing it more often. Beyond the routine schedule, you should rekey immediately after any of the six trigger situations listed earlier in this page.
For commercial properties with regular staff turnover, an annual rekeying schedule is a practical minimum. Property managers overseeing multiple units in Radnor or Upper Darby often build it into their tenant turnover checklist. Check our locks rekeying for landlords

Rekeying changes the internal pin configuration of your existing cylinder so only a new key operates it. The hardware stays in place. Replacement removes the entire lock and installs a new one. Rekeying is 50 to 70 percent cheaper when your hardware is in good working condition. We inspect your locks and give you an honest recommendation before quoting either option.
Each lock takes 10 to 20 minutes. A full home rekey covering three to five doors is typically complete in under an hour. Our technicians arrive in 5 to 10 minutes from our Devon base, so total time from your call to a secured home is usually well under two hours.
Yes. We work with all standard and high-security brands including Kwikset, Schlage, Medeco, Yale, Mul-T-Lock, and Baldwin. High-security cylinders like Medeco require brand-specific pinning kits, which our technicians carry on every vehicle.
