Fast, Reliable Residential Locksmith Across Florence-Graham
If you’re locked out of a unit on Compton Avenue or need a deadbolt swapped on a house near Nadeau Street, call (409) 405-4485 and get a written price before anyone is dispatched. We work throughout Florence-Graham, CA, and a big share of our residential calls here involve multi-unit buildings where the person at the door isn’t always the person who owns the hardware. That’s exactly the situation where a vague phone quote turns into a porch renegotiation, and it’s why our price is in writing before the tech leaves the van. Kevin Yoon leads the team, and every job carries the 365-Day Done Right Promise.
Why Preston Locksmith & Security Is Florence-Graham’s Preferred Residential Locksmith Company

You see a live arrival time on your phone, and we send before-and-after photos of every job. That’s The Relay Visibility Guarantee, and it applies to every residential call we run in Florence-Graham.
Our Residential Locksmith team handles lockouts, rekeys, deadbolt installation, and lock changes across Florence-Graham, including the older duplexes and triplexes along Alameda Street and the single-family pockets east of Central Avenue. We know the housing stock here, and we know how much of it is renter-occupied. That changes the job, and we’ll tell you exactly how before you spend a dollar.
Deadbolt Installation in Florence-Graham
Deadbolt installation in Florence-Graham typically runs $95 – $190 for a standard single-cylinder deadbolt, including the hardware and labor, with the written price confirmed before we start. In older Florence-Graham rentals and owner-occupied homes alike, a deadbolt is the single most effective upgrade you can make to an entry door, especially on units where the existing strike plate is barely holding in soft framing. We remove the old hardware, bore or ream the door if the existing prep doesn’t match, mount the new deadbolt with full-size screws into the frame, and test the throw so the bolt seats fully without rubbing.
When Your Florence-Graham Landlord Won’t Replace the Deadbolt
This comes up a lot in multi-unit Florence-Graham buildings. The landlord says the knob works, so the deadbolt isn’t a priority, but you want a deadbolt on your unit door. We can install one at your request as long as you have permission to alter the door, which brings up a point worth knowing: in a rental unit, the door and its hardware belong to the owner, not the tenant. Changing them without permission is a liability. We’ll ask who owns the door before we touch it.
What Deadbolt Installation Actually Involves
The job usually takes 45 – 75 minutes. We check the existing bore size, align the new bolt with the old strike plate or replace the strike plate entirely, and ensure the key turns without resistance. If the door is steel-clad, the prep is trickier and takes longer, which is reflected in the quote up front, not added later.
Locksmith Key Replacement in Florence-Graham
Locksmith key replacement in Florence-Graham runs $5 – $12 for a standard Schlage or Kwikset key copy and $30 – $65 per cylinder for rekeying, which is often the wiser move. Key replacement usually means one of two things: you need a new copy because yours snapped or you need the lock itself rekeyed because someone else’s key still operates it. In Florence-Graham’s rental-heavy market, the second situation is more common. A previous tenant moves out, and the new tenant wants assurance that old key in someone’s pocket doesn’t work anymore. Rekeying swaps the internal pins so old keys stop working, no new hardware needed. It’s faster and cheaper than replacing the lock.
Rekeying vs. Replacing: What Florence-Graham Tenants and Landlords Should Know
If the lock is a Schlage, Kwikset, or Medeco cylinder that’s in good shape, rekeying is almost always the right call. It costs a fraction of full replacement and takes about 15 minutes per cylinder. Replacement only makes sense when the lock is damaged, worn past reliable function, or you want a different finish or grade on the door. We’ll tell you which path fits your situation and quote the exact price for both before any work starts.
When a Key Snaps in the Florence-Graham Weather
Brass keys get brittle with repeated use, and coastal marine air that creeps up from the South Bay combined with the hot South LA summers can accelerate wear on cheaper key blanks. If a key breaks off in the cylinder, don’t force it. We extract broken keys without damaging the lock and cut a replacement on the spot, usually for under $35 on most standard residential cylinders.
Trusted Brands We Service in Florence-Graham
We’re trained and equipped to service Schlage, Kwikset, and Medeco hardware, along with Baldwin, Yale, Mul-T-Lock, Sargent, and Abloy. That means we stock common pins, cylinders, and tailpieces for the brands most often found in Florence-Graham’s older residential stock, and we’re familiar with the newer smart lock integrations that show up more on newer construction near the Alameda corridor. If your unit has an Abloy or Medeco high-security cylinder, we can rekey it according to the brand’s own system without sending you to a specialist. One tech, one visit, one written price.
Common Residential Locksmith Problems We See in Florence-Graham Homes
- Painted-over lock cylinders. Florence-Graham’s rental turnover often means quick paint jobs that cover the cylinder face and the screws holding the lock body. We see this constantly on Kwikset pin and tumbler knobs along Compton Avenue. It makes entry harder and often leads less careful techs to drill when a non-destructive latch entry would work.
- Landlord-tenant authorization tension. In a densely built, largely renter-occupied pocket of South LA, many residential lock calls are initiated by a tenant but legally require the property owner’s sign-off. If you rent in Florence-Graham, the door and its hardware belong to the owner. We’ll ask who authorizes the work before we change anything.
- Front gates with different keying than the unit door. Many Florence-Graham triplexes and fourplexes along Alameda Street have an outer pedestrian gate keyed to one set of keys and unit doors keyed to another. If you lose your keys, we only work the hardware you have a right to request service on. The gate stays untouched unless the owner requests it.
- Strike plates pulling out of old frames. Older Florence-Graham door frames are often soft from decades of screw movement. A deadbolt that worked for years suddenly won’t stay closed because the strike plate’s short screws have pulled free. Fixing this, not just replacing the lock, is what actually makes the door secure again.
On a Saturday call off Compton Avenue, a tenant in a triplex was locked out of her unit through a Kwikset pin and tumbler knob that had been painted over. Our tech used non-destructive entry through the latch rather than drilling the lock cylinder, then rekeyed the existing deadbolt and gave her a fresh key so the previous tenant’s copy stopped working. The landlord’s on-site gate key stayed untouched because we only worked the unit’s own hardware. That’s the standard we bring to every Florence-Graham residential call.

FAQs About Residential Locksmith in Florence-Graham
Yes, in almost every case. In a rental unit, the door and its hardware belong to the property owner, not the tenant, so you need the landlord or property manager’s authorization before we can rekey a lock. If you’re a tenant in Florence-Graham and want your unit rekeyed, have your landlord call us or put the request in writing. Once that’s clear, we’ll rekey the existing hardware and confirm the price before we start. Call (409) 405-4485 and we’ll walk you through the exact authorization you need.
In most cases, yes. We use non-destructive entry techniques on standard residential locks, including painted-over Kwikset knobs like the ones we regularly see in Florence-Graham’s older triplexes. Drilling is a last resort, and we’ll tell you before we do it and confirm the cost. The price you get on the phone is the price on the invoice, drilled or not.

Yes, as long as the property owner or manager authorizes access.

If the deadbolt works and you just want old keys to stop working, rekey it. In Florence-Graham, rekeying runs $30 – $65 per cylinder and takes about 15 minutes.
