Fast, Reliable Rekey Locks Across Montclair
If you’ve just moved into a house off Holt Boulevard or handed a spare key to a contractor near Monte Vista Avenue and never got it back, you need your locks rekeyed. Rekeying actually means swapping the internal pins inside the lock cylinder so your old keys stop working entirely, no new hardware required. In Montclair, we typically arrive within 60 to 90 minutes of your call, and Kevin Yoon’s team at Preston Locksmith & Security will give you a written per-lock price before anyone is dispatched to your door. Call (409) 405-4485 for a free estimate right now.
Why Preston Locksmith & Security Is Montclair’s Preferred Rekey Locks Company
We work in Montclair every week, and we know the housing stock here. The 1950s and 60s tract homes near Holt Blvd often still have their original mortise lock bodies, while the newer infill along the 10 freeway corridor tends to carry builder-grade deadbolts. That mix matters because a rekey quote given over the phone for a “standard lock” can change the moment our tech sees whether the door has a Schlage deadbolt or an older Baldwin mortise cylinder. We quote per lock only after confirming the cylinder type, and that written price is the price you pay, no arrival surcharge, no bill that swells between the estimate and the invoice.
Every Preston Locksmith & Security technician arrives in uniform, background-checked, and ready to show company ID at your door. Calls are answered by a live person 24/7, so when you call Montclair from your phone at 9pm you’re not leaving a voicemail and hoping. And every rekey job carries the 365-Day Done Right Promise: if it’s not done right, we make it right, backed by a written guarantee stamped on every repair, including a free second visit if something fails.
Locksmith Rekey in Montclair
Locksmith Rekey in Montclair means one of our uniformed techs drives to your address, identifies each lock cylinder on the property, and re-pins the internal tumblers so every old key is rendered useless. A homeowner calls us for this right after closing on a house near Mills Avenue, after a roommate moves out of an apartment near the Montclair Place mall, or when a housekeeper, dog walker, or ex-contractor still holds a key. The work itself usually takes 20 to 45 minutes for a typical front door, back door, and garage access door, and we confirm the per-cylinder price in writing before a single tool leaves the bag.
What the tech actually does
The cylinder comes out of the knob or deadbolt, the old pins are dumped, and a fresh pin and tumbler set is inserted to match a new key. Your existing hardware stays in place. Old keys stop working immediately.
After the rekey
You get new keys cut on the spot, we test every lock twice, and you receive a digital invoice with a pay link plus before-and-after photos. That’s The Relay Visibility Guarantee at work.
Rekey Door Lock in Montclair
Rekey Door Lock in Montclair typically means a homeowner wants one key to operate every exterior door. The most common request we get near the 10 freeway corridor is a “keyed alike” service: front door, back door, and side garage door all matched to a single key. A single door rekey in Montclair generally runs $45 to $95 per cylinder depending on whether it’s a standard Kwikset or Schlage deadbolt. Homes with multiple doors usually fall between $120 and $250 total because we rekey each cylinder individually.
Mortise locks are different
Older Montclair homes off Holt Blvd often have mortise lock bodies built into the door edge, not a simple cylindrical deadbolt. Those take longer to disassemble and re-pin, which is why we confirm the lock type before quoting.
When to rekey versus replace
If the existing hardware is in solid shape, rekeying is almost always the smarter spend. You keep the original finish and fit. Replacement only makes sense when the lock is physically worn, rusted, or you want to upgrade to a smart lock or higher-security cylinder.
Trusted Brands We Service in Montclair
Our techs are trained on premium lock brands including Medeco, Mul-T-Lock, and Abloy alongside everyday Schlage, Kwikset, and Yale hardware. That means when we rekey a Montclair home, we’re not one-trick installers. We can re-pin a builder-grade Kwikset knob on a 1960s tract house, then walk to the back door and shim the plug on an original Baldwin mortise body without blinking. We stock common Schlage and Kwikset pin kits in our service vehicles, so most Montclair rekeys are completed in a single visit with no parts run back to a shop.
Common Rekey Locks Problems We See in Montclair Homes
- Worn cylinders on original 1950s-60s locks. The brass pins inside have rounded over decades of use, so a straight rekey without shimming the plug can leave the new key sticky or unreliable. We inspect and shim where needed before re-pinning.
- Builder-grade Kwikset knobs with loose tolerances. These are everywhere in Montclair’s tract home inventory. They rekey fine, but if the cylinder is heavily worn we’ll tell you honestly whether rekeying is worth it or whether a new Schlage deadbolt is the better long-term call.
- Doors with mismatched hardware from previous handyman work. We regularly see a Schlage deadbolt paired with a no-name knob on the same door. We can rekey both, but keying them alike sometimes means a cylinder swap or a new keyway.
- Contractors or previous owners still holding keys. The most common rekey trigger in Montclair is a renovation where multiple subs had access, or a home purchase where the seller never turned over all copies. Rekeying eliminates that risk in under an hour.
Pricing for Rekey Locks in Montclair, CA
A straightforward single-cylinder rekey in Montclair runs $45 to $95 per cylinder. Most homes with two or three exterior doors land between $120 and $250 total. Mortise lock bodies take longer and typically add $25 to $45 per lock because the cylinder extraction and re-assembly is more involved. High-security cylinders from Medeco or Mul-T-Lock run higher because the pin kits themselves cost more. You will always get a written price before we start, and that written price is the price on your invoice. No call-out surcharge added on arrival, no bait pricing. Call (409) 405-4485 and we’ll confirm the per-lock number over the phone based on what you tell us about your doors, then lock it in writing before our tech leaves the shop.

Twenty to forty-five minutes for a standard front door, back door, and garage access door with cylindrical deadbolts. Older mortise locks off Holt Blvd can add 15 to 20 minutes per door. We usually complete the whole job in a single visit.
Almost always, yes. The 1950s and 60s homes around Holt Blvd and Monte Vista Avenue often have original mortise lock bodies, and we re-pin those regularly. The cylinder comes out differently than a standard deadbolt, but we have the pin kits and the experience to do it on site. If the body is physically broken or rusted through, we’ll show you what we see and give you a replacement price before proceeding.
Every technician arrives in a Preston Locksmith & Security uniform, carries company ID, and can show you the written price before touching a tool. The Relay Visibility Guarantee also sends you the tech’s live trackable arrival time before they knock, so you know exactly who is coming and when. If someone at your door can’t produce ID, don’t let them in.
Rekeying changes the pins so old keys stop working and new keys operate your locks. A master key system means different keys open different doors, while one master key opens everything. In Montclair, we set up simple residential master key systems for homes with separate tenant doors or a detached ADU, and the per-lock rekey price still applies to every cylinder in the system. Call (409) 405-4485 and we’ll map out the exact configuration you need.
