Why Preston Locksmith & Security Is Del Aire’s Preferred Rekey Locks Company
Del Aire is a small, unincorporated pocket of Los Angeles County, and we treat it that way. Our techs know the tract-home layouts, the older Kwikset and Schlage hardware on these doors, and the fact that a rekey job here rarely means replacing hardware, it means repinning what’s already there and doing it right. Kevin Yoon leads Preston Locksmith & Security, and he built our Rekey Locks team around one rule: the price you agree to on the phone is the price on the invoice. No dispatch fee surprises, no “your locks are too old to rekey” upsell once we arrive.
Our customers in Del Aire tend to call for the same reasons. A new home purchase, a roommate or tenant change, a lost key, or a falling-out with someone who still has a copy. We answer the phone with a live person, 24/7, which matters when you’re standing in your driveway at 9pm wondering whether a spare key is floating around. Every technician is background-checked, uniformed, and arrives with a trackable live arrival time, so you know exactly who is pulling up and when.
Rekey House in Del Aire
A Rekey House job in Del Aire means changing the internal pins inside every lock cylinder on the property so that every old key stops working, without swapping out the hardware itself. For a typical 1950s tract home in the 90250 ZIP, that usually means three to five cylinders: front entry, side door, a deadbolt or two, and maybe a sliding door. We rekey each cylinder to a keyed-alike setup unless you tell us otherwise, so one key operates every door you want it to.
What the work physically involves
Our tech removes each lock cylinder, dumps the old pins, and installs new pins matched to a fresh key cut. No drilling, no damage to the door. The whole job on a standard Del Aire home runs about half an hour. If you want some doors on a different key than others, we set that up on site at no extra charge.
When this is the right call
Just closed escrow on a house near Del Aire Park? The seller’s agent, the prior owner, a housesitter, a contractor, a dog walker, and who knows who else may still have keys. Rekeying kills every one of those copies the same day. It’s also the right move after any break-in attempt or when a key goes missing and you can’t account for every copy.
Lock Rekey in Del Aire
A Lock Rekey in Del Aire usually involves a single cylinder, a deadbolt, or a handful of locks on one door, and it runs $85 to $160 per cylinder plus the service call. This is the job for partial access changes: you want a new roommate to have a key, but not access to the garage; you want the front door changed but the back door left alone; you want a specific key killed while keeping all others working. We handle these on a per-cylinder basis and give you the written total before any work starts.
Killing one key, keeping the rest
You can absolutely keep some keys working and retire others. We’ll pin the cylinder so the key you want dead no longer turns, while the keys you want to keep still work. That’s standard, not an upgrade. For landlords with a four-unit building near the 405, we can set up a master key system where tenants each hold one key for their unit and you hold a single master for everything.
When a rekey isn’t enough
If the lock cylinder is worn to the point that a key drags or jams, we’ll tell you before we quote, not after we start. Sometimes the fix is still a rekey, sometimes it’s a $25 cylinder swap. You’ll know which one and what it costs before we touch the door.
Trusted Brands We Service in Del Aire
Most doors in Del Aire are wearing Kwikset and Schlage hardware, and we stock pins, springs, and common replacement cylinders for both, so we rarely have to leave mid-job to chase a part. We also rekey and service Medeco, Baldwin, and Abloy hardware for the handful of homes and small offices here that stepped up to high-security cylinders, and we’re factory-trained on those systems, not winging it with a universal pin kit. If your Del Aire door is still running the original builder hardware from the 1960s, we can rekey it, or we can walk you through what an upgrade looks like, at a price you approve first.
Common Rekey Locks Problems We See in Del Aire Homes
- Builder-grade Kwikset and Schlage cylinders from the 1950s and 60s. These are simple pin-and-tumbler locks that rekey perfectly well, but if the springs are tired, the new key might feel loose. We check for that and tell you before we quote.
- Worn strike plates and door sag. A rekey fixes the key, not the door frame. If your deadbolt has been dragging against the strike plate, we’ll point it out and give you a price to correct it, because a rekeyed lock on a sagging door is still a door that doesn’t latch cleanly.
- Mixed keyways across the house. Del Aire tract homes often have a front door Kwikset and a back door Schlage, or vice versa. That means two different keys unless we convert one to match the other. We do that on site when it’s possible and quote it up front.
- A previous “rekey” that was just a cheap pin swap. Some low-bid outfits change pins but leave the wrong cylinder cap or a loose tailpiece, and the lock fails within a month. We test each cylinder through a full lock and unlock cycle before we leave.

FAQs About Rekey Locks in Del Aire
A full-house rekey on a standard Del Aire home, meaning four or five cylinders, takes 30 to 45 minutes once the tech is inside. Single-lock jobs are done in 15 to 20 minutes. The service call itself is usually dispatched same day, and our live arrival tracker shows you exactly when we’ll be at the door. Call (409) 405-4485 for a time estimate for your street.
No. A properly done rekey means removing the cylinder with the existing key, replacing the internal pins, and reinstalling it. Drilling is only ever needed when a lock is damaged or a key is broken off inside, and if that’s the case on your Del Aire door, we’ll show you and get your approval before any drilling starts. The written price still applies.
Every Preston Locksmith & Security tech arrives in uniform, in a marked vehicle, with a company ID that includes their photo and name. You also get a live arrival link before they show up, so you can watch the vehicle approach your street in real time. We do not send anonymous subcontractors in unmarked vans. If someone at your Del Aire door claims to be us but has no ID and no trackable arrival, it’s not us.
Yes. We rekey cylinders individually, so we can retire one tenant key while leaving all other copies functional, or set up a master key system where you hold one key for every unit and each tenant’s key only works on their own door. This is common for the small multi-unit buildings near Aviation Boulevard. The per-cylinder price covers the setup.
Yes, in nearly every case. These older pin-and-tumbler locks rekey cleanly and the new key will turn smoothly if the cylinder itself isn’t physically worn out. If the cylinder is too far gone, we’ll tell you before quoting and give you the option to rekey what’s salvageable or swap a cylinder for around $25. You approve every dollar before we begin.
