Rekeying locks in Paramount is the service we handle most often here, and for good reason. The city’s dense mix of 1940s-1970s rental apartments and long-time owner-occupied bungalows means keys change hands constantly, and old hardware takes a beating from sun-baked dust and years of wear. Greystone Locksmith has served Paramount since 2011, and we stock the parts to rekey Schlage, Kwikset, Yale, and Baldwin cylinders the same day we arrive. Call (866) 497-9415 for a free estimate, and we’ll tell you honestly whether rekeying or replacing is the smarter move for your doors.
Why Paramount Homes Are Different
Paramount sits in the heart of the Gateway Cities stretch of southeast LA County, and the housing here shapes nearly every lock job we take. The city is almost entirely within the 90723 ZIP code, and a large share of homes went up between the 1940s and 1970s. That means single-story stucco bungalows and low-slung duplexes and fourplexes dominate, with a healthy stock of older rental apartments mixed in. Many of these buildings still carry their original knob locks, single-cylinder deadbolts, and weathered wood or metal door frames that need retrofitting when you move to modern hardware.
The climate adds another layer. Hot, dry inland summers and Santa Ana wind events push dust and grit into exterior mechanisms, so cylinders and deadbolts on gates and entry doors wear faster than you’d expect. A lock that worked fine in April can feel stiff and gritty by September. All of that means we’re not just swapping pins. We’re often straightening strike plates, lubricating sun-abraded cylinders, and fitting new hardware into doors that have shifted over decades. Paramount is a compact, high-turnover rental market too, so a landlord rekeying a unit on Monday often means a tenant lockout on Thursday. We schedule for that reality.

Our Main Paramount Services
The two services homeowners, renters, and property managers in Paramount call on most are car key replacement and emergency lockouts. Here’s what each one involves in this city.
Car Key Replacement in Paramount
Losing a car key on a residential street in Paramount is a different problem than losing one at a mall. There’s no parts counter nearby, and a tow to a dealer in a neighboring city can eat an entire afternoon. We cut and program replacement keys, including transponder and remote-head keys, in the field, so you’re not stranded. Dust from the LA basin’s dry air is rough on worn ignition cylinders too, and we sometimes find a key that won’t turn because the cylinder itself is packed with years of grit. We’ll tell you if it’s the key or the lock before you spend on the wrong fix. Car Key Replacement in Paramount covers the full range of what we handle curbside.

Emergency Locksmith in Paramount
A lockout at a fourplex off a residential side street in Paramount often means a landlord in another city and a tenant standing on the porch with groceries. We get there quickly because most of the city is within a short drive, and our techs carry the tools to open Kwikset, Schlage, Yale, and Baldwin hardware without wrecking the door. When the lock is decades old and already failing, we can rekey or replace it on the spot, which saves a second trip. Emergency Locksmith in Paramount spells out response times and what we handle after hours.

Rekey Locks in Paramount
Rekeying in Paramount is often the smarter move than replacing, because so much of the housing stock here still has solid, serviceable hardware from the 1940s through the 1970s. A new tenant moves in, an old roommate moves out, or a contractor never returned a key, and the fix doesn’t have to be four new locksets. We change the pins inside the cylinder so the old key stops working and a new one operates the lock. The hardware stays put, the cost stays down, and the job is usually done in under an hour. That’s the core of what we do, and it’s why we treat Rekey Locks as a core service, not an upsell.
Lock Rekey
Signs you need it
You’ve moved into a Paramount home or apartment and don’t know who else has a copy of the key, or a relationship ended and a key never came back.
What it costs in Paramount
A standard single-cylinder lock rekey in Paramount typically runs $65 – $120, depending on the brand and cylinder type.
How we do it
We remove the cylinder, swap the pins to match a new key, test the lock for smooth operation, and hand you the new keys on the spot.
Rekey Door Lock
Signs you need it
Your landlord just turned over the unit, you lost a key and want the lock changed without buying new hardware, or you bought a foreclosure in Paramount and aren’t sure who holds old copies.
What it costs in Paramount
Rekeying a door lock on a typical Paramount bungalow runs $65 – $120 for the first cylinder and $20 – $40 for each additional cylinder keyed alike.
How we do it
We confirm the lock’s brand, match the pin profile to a freshly cut key, and reset the cylinder so every old key is dead.
Keyed Alike
Signs you need it
You carry three keys for one house and want a single key to operate the front door, back door, and garage side door.
What it costs in Paramount
Keying multiple locks alike in Paramount starts at around $65 – $120 for the first lock, with $20 – $40 per additional cylinder matched to the same key.
How we do it
We re-pin every cylinder in the set to a shared key code, confirm all locks turn with one key, and label nothing, so the old keys quietly stop working.
What Rekey Locks Costs in Paramount
| Item | Typical range in Paramount |
|---|---|
| First cylinder rekey (standard) | $65 – $120 |
| Each additional cylinder keyed alike | $20 – $40 |
| High-security cylinder rekey (Medeco, Mul-T-Lock) | $100 – $180 |
How long does a rekey take in Paramount?
Most single-family and apartment rekeys in Paramount take 30 to 60 minutes once we arrive. Multi-unit buildings with several doors keyed alike can run two to three hours. Call (866) 497-9415 to schedule a window that works.
Should I rekey or replace my locks after moving in Paramount?
If the hardware is sound and you just want old keys dead, rekeying costs less and keeps original hardware. If cylinders are worn, corroded, or you want a security upgrade, replacement makes more sense. We’ll tell you which fits your situation.
Brands We Service in Paramount
Greystone Locksmith works on the lock in front of us, not just the brands we prefer. That means we’re ready for the Kwikset and Schlage hardware common in Paramount’s older homes, the Yale and Baldwin sets on nicer entries, and the Medeco and Mul-T-Lock cylinders we see on commercial doors along the Alameda corridor. Our techs carry pins, springs, and common replacement parts for these brands in our service vehicles, so most rekeys and repairs happen in one visit. For our full rundown, see our brands.

In Paramount, prices move with two local factors: the age of the hardware and how much sun-abraded grit has worked its way into the cylinder. Homes with original knob locks and misaligned door frames often need a little extra labor to get everything turning cleanly. Whatever the job, we quote the full price on the phone before anyone is dispatched, and that is the price on your invoice. No call-out surcharge added on arrival, ever.

What Paramount Customers Say
"Rekey was done properly. One of the keys he cut was slightly stiff in the back door and I had to call him to swap it, which he did without a fuss."
— Neil Mehta"Locked out at eleven at night with a kid asleep in the car. He was there in 25 minutes, had the door open in under two, and did not do the thing where the price goes up once he's standing in front of you."
— Shannon Hoffman"Key snapped off in the deadbolt. He extracted it without damaging the cylinder, which I did not think was going to be possible."
— Beatriz Torres
