Rekeying locks is the service we perform most often in Kensington, and the town’s housing stock explains why: hundreds of 1920s to 1960s detached homes still carry original mortise locksets and brass hardware that new homeowners want secured before move-in. The seasonal swelling and shrinking of wooden door frames from Mid-Atlantic humidity means many of those locks also need realignment or retrofitting rather than a simple cylinder swap. If you’ve just bought a bungalow near Connecticut Avenue or need a rental unit rekeyed on Knowles Avenue, call Coral Locksmith at (855) 382-1343 for a straight answer and an honest price.
Why Kensington Homes Are Different
Kensington grew as an old streetcar suburb, and most of its housing stock dates from the 1920s through the 1950s: bungalows, Colonials, and post-war capes on compact lots. That age matters for locksmith work. Many original entry doors still have mortise locksets rather than modern cylindrical deadbolts, which means rekeying often involves working inside the lock body and sometimes replacing worn internal springs. Glass-paneled front doors are common on the side streets, and they create a security issue we see regularly: a single-cylinder deadbolt can be bypassed by breaking the glass and reaching through. We frequently recommend double-cylinder deadbolts or reinforced strike plates on those doors.
The local climate works against exterior hardware. Freeze-thaw cycles each winter cause wooden doors and frames to swell and warp, which throws strikes out of alignment by spring. Summer humidity makes it worse. Exterior brass and steel corrode faster here than in drier climates, especially on homes near salted roads in winter. When we rekey a Kensington home, we typically check the strike alignment and bolt throw at the same time, because a newly rekeyed lock still sticks if the door has shifted a quarter inch since November.
There’s no apartment-tower inventory here and no big-box retail corridor inside town. Most jobs are residential, many are for repeat customers, and quite a few happen within a few blocks along Connecticut and Knowles Avenues. People in Kensington tend to stay in their homes for decades or buy from a renovator who flipped the house, so the work skews toward rekeying, retrofitting vintage hardware, and quiet preventive upgrades, not high-volume commercial master-key systems.
Styles & brands we work with







Our Main Kensington Services
Two services account for most of the calls we take from Kensington residents, and each has a dedicated page with the full detail: car key replacement and emergency lockout response.
Car Key Replacement in Kensington
Losing a car key on a street with no dealership anywhere nearby turns into a real disruption. We replace car keys directly, including transponder keys and fobs, without the wait or markup a dealership adds. Kensington’s narrow side streets and driveway-only parking mean most jobs happen at the home rather than a parking lot, which works in your favor: we come to the vehicle. If you need a spare key cut or a lost key replaced, Car Key Replacement in Kensington covers what to expect.

Emergency Locksmith in Kensington
Locked out of a house on a February night in Kensington, when the temperature is below freezing, is exactly the situation where you want a calm voice and a fast arrival. Our emergency service covers residential and automotive lockouts, stuck deadbolts, and locks that fail after a break-in attempt. Older mortise locks on 1940s doors fail unpredictably, and when they do, it tends to be at the worst time. Emergency Locksmith in Kensington explains response expectations and what to check before you call.

Rekey Locks in Kensington
Rekeying in Kensington is usually the smartest first move after buying one of the town’s older homes, because you have no way of knowing how many copies of the old key floated around over the decades. These 1920s to 1960s houses have passed through multiple owners, tenants, contractors, and sometimes a full renovation crew, and every one of those people could have held a key. Rather than replace working vintage hardware, we rekey the cylinders so the old keys stop working while the original brass and mortise bodies stay in place. That preserves the character of a Kensington entry door and costs far less than new hardware. Our full rekeying process is on the Rekey Locks page.
Lock Rekey
Signs you need it
You’ve just moved into a house in Kensington, a key has gone missing, or a tenant has moved out and you don’t know whether their key was copied.
What it costs in Kensington
Rekeying a standard lock in Kensington typically runs $65 – $180 per lock depending on cylinder type and hardware brand.
How we do it
We disassemble the cylinder, replace the internal pins so the old key no longer turns, cut new keys, and test the lock through several cycles before we leave.
Rekey Door Lock
Signs you need it
Your mortise lock or deadbolt works fine mechanically, but you want all exterior doors on one key or need to shut out someone who had a key.
What it costs in Kensington
Expect $15 – $20 per cylinder in labor plus parts, with many Kensington homes having two or three exterior cylinders to rekey.
How we do it
We remove the lock from the door when needed, rekey the cylinder to a new key code, then reinstall and align it with the strike plate so the bolt throws cleanly.
What Rekey Locks Costs in Kensington
| Item | Typical range in Kensington |
|---|---|
| Rekey standard lock cylinder | $65 – $180 per lock |
| Labor per cylinder | $15 – $20 |
| Service call / trip charge | $50 – $100 |
How much does it cost to rekey locks after moving into a Kensington home?
Most Kensington homes have two or three exterior cylinders, so the typical move-in rekey totals $180 – $450 including the service call. Older mortise locks may run toward the higher end of that range because the cylinder takes longer to remove and reinstall. Call (855) 382-1343 for a precise quote before we dispatch.
Can you rekey vintage mortise locks in older Kensington houses?
Yes, we rekey original mortise locksets regularly, including the brass hardware common on 1920s and 1930s Kensington doors. If the internal springs or tailpiece are worn, we can replace those parts, and we will tell you before doing any work beyond rekeying.
Brands We Service in Kensington
We work across Schlage, Kwikset, Medeco, and Yale hardware, which covers most of what’s installed in Kensington homes. Because the town’s older houses often mix brands from different decades, we stock common cylinders, pins, and tailpieces in the truck so a rekey doesn’t stall waiting on a part. See our brands for the full range, including high-security lines like Medeco.
Pricing for Locksmith in Kensington, MD

|---|---|
| Rekey lock (per lock) | $65 – $180 |
| Rekey labor (per cylinder) | $15 – $20 |
| Service call / trip charge | $50 – $100 |

In Kensington specifically, the age of the lock drives the biggest price swing: a 1950s mortise cylinder takes more time than a modern Kwikset deadbolt, and warped door frames on older homes often need strike adjustment before a rekeyed lock will throw cleanly. Whatever the estimate, the price we quote on the phone is the price on your invoice, with no dispatch fee added on arrival.

What Kensington Customers Say
"Quoted a price on the phone and honored it. After the last locksmith I called, that alone is worth a review."
— Ebony Ingram"Rekeyed every lock in the house the day after we closed. Six doors, all matched to one key, done in about ninety minutes."
— Shanice Dawson"The old deadbolt was mounted crooked by whoever lived here before and had been sticking for years. He redrilled and reset it properly rather than just replacing the hardware."
