Rekeying locks is the service Rockville homeowners ask for most, and it’s not close. The city’s post-war brick ramblers, split-levels, and newer townhomes all share the same security reality: locks that have seen decades of keys, tenants, and weather. In Rockville’s humid summers and freeze-thaw winters, exterior deadbolts stick, corrode, and misalign, which makes rekeying as much about fit and finish as it is about new pins. Coral Locksmith has served Rockville since 2018, working across Kwikset, Medeco, Yale, and Baldwin hardware. Call (855) 382-1343 for a rekey quote that’s the same price on the invoice as it is on the phone.
Why Rockville Homes Are Different
Rockville’s locksmith work is shaped by a housing stock most cities don’t have. The 20850 through 20853 core is dense with mid-century planned-community housing: 1950s and 1960s brick ramblers, split-levels with original mortise locksets, and builder-grade knob locks that were never upgraded to proper deadbolts. A huge share of jobs in Rockville are rekeys and security upgrades on these older single-family homes rather than emergency break-ins, because the city’s large federal and scientific workforce tends to be security-conscious and proactive about who has keys.
The climate does real work on exterior hardware. Rockville’s humid Mid-Atlantic summers swell wooden doors, throwing off strike alignment, and freeze-thaw winters cause deadbolts to freeze and internal springs to fatigue. A lock that works fine in October can bind in January. That’s why a Rockville rekey isn’t just swapping pins: it means checking door-to-frame fit, adjusting strike plates, and making sure the hardware will cycle cleanly through a full Rockville winter.
The 20851 and 20853 corridor is a good example. Homes there often have original 1960s mortise locks that homeowners want rekeyed rather than replaced. Doing that correctly means hand-fitting old mortise bodies to modern deadbolt standards while matching the existing finish, which is slow, precise work that most locksmiths won’t quote honestly. We do it regularly, and we’re comfortable saying so.
Styles & brands we work with
Our Main Rockville Services
Rockville homeowners call Coral Locksmith most for two things: car key replacement and emergency lockouts. Each has its own dedicated Rockville page with full pricing and details, linked below.
Car Key Replacement in Rockville
Losing a car key in Rockville usually means a tow to a dealership and a three-figure bill for the privilege. We handle car key replacement directly, without dealership wait times or markups, for most major makes. Rockville drivers often discover us in parking lots near Rockville Town Center or the Twinbrook Metro area, where a broken or lost key strands the car. Read the full breakdown on our Car Key Replacement in Rockville page, including transponder and fob programming specifics.
Emergency Locksmith in Rockville
A locked-out situation in Rockville rarely happens at a convenient time. Whether it’s a deadbolt that won’t retract on a 1960s rambler or a front door that swelled shut in July humidity, emergency response is about speed and calm resolution, not panic. We walk you through what we’ll do before we arrive, and we quote the full price on the phone before anyone is dispatched. See our Emergency Locksmith in Rockville page for what’s covered and how quickly we can reach your part of the city.

Rekey Locks in Rockville
Rekeying a lock in Rockville is the most common job we do, and the housing stock is the reason. Homes built in the 1950s through 1970s in the 20851 and 20853 corridors often still have their original mortise locksets or builder-grade knob locks. In a city where many residents work for federal agencies or scientific employers, security-conscious homeowners rekey on move-in, after a tenant change, after a lost key, and before handing a key to a contractor. Rockville’s humid summers and freeze-thaw winters also mean exterior locks wear faster, so rekeying here routinely includes realigning strike plates and freeing corroded cylinders, not just dropping in new pins. That’s the job, and that’s what separates a proper rekey from a pin-swap. If you want the fuller picture on how rekeying compares to replacing hardware across brands, see our Rekey Locks service page.
Lock Rekey
Signs you need it
You’ve moved in, a tenant has moved out, a key has gone missing, or you have no idea how many copies of your house key are floating around Rockville.
What it costs in Rockville
A standard residential lock rekey in Rockville typically runs from $20 to $60 per lock depending on the cylinder type and whether we’re also correcting door-to-frame fit.
How we do it
We remove the cylinder, replace the pins and springs to match your new key, lubricate and reassemble, then test the lock through a full cycle and correct any strike misalignment caused by Rockville’s seasonal door swell.
Locksmith Rekey
Signs you need it
You’ve bought a home in an older Rockville neighborhood like the 20851 corridor and you don’t know who the previous owner gave keys to.
What it costs in Rockville
Most Rockville homes with two exterior doors and one deadbolt run $75 to $170 total when we come to you, depending on the hardware condition.
How we do it
We key all exterior locks to a single new key, so one key works the front door, back door, and deadbolt, and we check that each cylinder is in serviceable condition before we pin it.
Rekey Door Lock
Signs you need it
Your door lock sticks, is hard to turn in freezing weather, or you want a fresh key after a divorce, roommate change, or lost key.
What it costs in Rockville
A single door lock rekey in Rockville is typically $20 to $60 plus the trip, and if the lock is too corroded to rekey reliably we’ll tell you before doing anything.
How we do it
We remove the lock from the door, strip and inspect the cylinder, replace the pins, reassemble, and test the key and knob, making sure the latch lines up cleanly with the strike.
Rekey Service
Signs you need it
You’re a Rockville landlord rotating tenants, a property manager onboarding new staff, or an owner who just wants every lock in the house on a single key.
What it costs in Rockville
Multi-lock rekey service across several units or doors typically runs $20 to $60 per lock, with volume pricing on larger Rockville properties.
How we do it
We come to your Rockville property with the pins and key blanks for your hardware tier, key every cylinder on-site, and leave you with a working keyed-alike system before we go.
Keyed Alike
Signs you need it
Your keychain has four different keys for five doors and you want one key that works everything.
What it costs in Rockville
Keyed-alike rekeying in Rockville runs $20 to $60 per cylinder, and there’s no premium for making all cylinders match the same key.
How we do it
We pin every cylinder to a shared key code, then physically test each lock with the same key, including deadbolts, knob locks, and any mortise locks in older Rockville homes.
What Rekey Locks Costs in Rockville
| Item | Typical range in Rockville |
|---|---|
| Per-lock rekey (standard residential cylinder) | $20 – $60 |
| Multi-lock rekey (volume or keyed-alike) | $75 – $170 |
| Deadbolt rekey with strike realignment | $20 – $60 per lock |
How long does rekeying take in Rockville?
A typical Rockville home with two or three exterior locking points takes 30 to 60 minutes on-site. Older mortise locks in 1950s and 60s housing can take longer, and if yours is one of those, call (855) 382-1343 and we’ll tell you straight.
Can you rekey a lock that’s frozen or rusted?
Usually yes. Rockville’s humid summers and freeze-thaw winters corrode cylinder internals, but most clean up fine. If the cylinder is beyond safe rekeying we’ll stop, show you the problem, and quote replacement before doing anything. Call (855) 382-1343 to talk it through.

We service the full range from consumer-grade to high-security, and we tell you if a lock is worth rekeying or better off replaced.
