Fast, Reliable Rekey Locks Across Covina
Rekeying a lock in Covina typically costs $25 to $45 per cylinder for standard pin-and-tumbler hardware, and most single-family homes take under an hour once we’re on site. That price gets confirmed in writing before anyone is dispatched, so the number you agree to on the phone is the number on your invoice. If you’re holding a new set of keys after closing escrow on a house off Badillo Street or you just fired a roommate and want every door changed, call (409) 405-4485 and we’ll scope the job by your home’s build era and lock type.
We know Covina’s housing stock because we work on it every week. A 1950s ranch near downtown needs a different approach than a 1990s tract home up in the northern hills, and the quote should reflect that before we roll out. The Relay Visibility Guarantee backs every job: a live trackable arrival time, before-and-after photos, and a written price locked in before the first tool leaves the bag.
Why Preston Locksmith & Security Is Covina’s Preferred Rekey Locks Company
Covina homeowners call us because we answer the phone with a live person and give a written price before dispatch. No voicemail trees, no callback queues, no anonymous technician showing up with a vague hourly rate. Kevin Yoon leads our team, and every technician who arrives in Covina is background-checked and in uniform. You’ll know who is coming, what they look like, and when they’ll knock.
Our work across Covina covers everything from a single deadbolt rekey on a condo near the 10 Freeway to whole-house key control on ranches off Citrus Avenue. The 365-Day Done Right Promise applies to every rekey we perform: if it’s not done right, we make it right, and the written guarantee comes stamped on every job. Founded in 2008 and part of the Relay Home Co. family, this location is independently owned and operated. Dispatch and scheduling are coordinated from the brand’s Los Angeles office, and crews serve Covina locally.
We stock common pin kits and cylinder parts for Covina’s specific mix of hardware, which keeps most rekey jobs to a single visit. Whether you have original Kwikset cylinders from a 1960s bungalow or a Baldwin deadbolt installed last year, our techs carry what’s needed to re-pin on the spot instead of ordering parts and making you wait.
Rekey Deadbolt in Covina
Rekey Deadbolt work in Covina means replacing the internal pins and springs inside your existing deadbolt cylinder so old keys stop turning it, no new hardware required. This is the single most common job we do across the city, especially after a tenant moves out of a duplex near Glendora Avenue or a home changes hands in the neighborhoods around Covina High School. In Covina, rekeying a standard deadbolt runs $25 to $45 per cylinder depending on whether it’s a builder-grade Kwikset or a higher-security Medeco or Baldwin cylinder that needs matched pins.
What the job involves
Our tech pulls the cylinder, removes the plug, and swaps the pin stacks to match a new key. Worn builder-grade cylinders often need the plug cleaned before new pins seat correctly, which is common on Covina homes built in the 1980s and 1990s. We hand you the old pins in an envelope so you can see exactly what changed.
When Covina homeowners need it
You need a deadbolt rekey after eviction, roommate turnover, a lost key, or any time you can’t account for every copy of a house key. If one deadbolt on the front door is rekeyed but the back door, garage entry, and side gate still take the old key, you don’t have key control. We check every exterior lock during a rekey and flag anything still on the old key.
Rekey House in Covina
Rekey House service in Covina means re-pinning every exterior lock on the property so one new key operates all of them, and every old key stops working. For a typical 3-bedroom Covina home with three to four exterior doors, expect $75 to $180 total depending on cylinder count and whether any pre-1960 mortise locks are in play. The price per cylinder is the same whether we do one lock or six, and the full written quote is confirmed on the phone before dispatch.
All doors on one key
Most Covina homeowners want every door, plus the garage entry and side gate if it has a keyed lock, working off a single new key. We can match cylinders with different keyways to one key in many cases, but some older mortise locks need a dedicated cylinder swap to join the same key system. Our tech will tell you on site if any hardware can’t be keyed alike without replacement.
Key control after closing
Escrow closings are the biggest driver of whole-house rekeys in Covina. The seller’s keys are never fully accounted for, and the only way to reset access is to re-pin every exterior cylinder. We were dispatched to a 1950s ranch off Citrus Avenue near downtown Covina where the new owner had just closed and every door still took the seller’s keys. Our tech pulled two original Kwikset pin-and-tumbler cylinders and an older mortise lock on the front door, re-pinned all three to a new set of five keys, and handed the homeowner the old pins in an envelope so they could see exactly what had been swapped. No drilling, no new hardware, all three doors on one key before we left.
Trusted Brands We Service in Covina
Our techs rekey Kwikset, Schlage, Yale, Baldwin, Medeco, Mul-T-Lock, Sargent, and Abloy hardware daily across Covina, from builder-grade residential deadbolts to high-security commercial cylinders. We keep common pin kits and cylinder parts stocked for the brands Covina homes actually have, which means most rekey jobs finish in one visit. If your Covina property has a Kwikset from the 2000s, a newer Baldwin on the front door, or a commercial Medeco cylinder at your shop off San Bernardino Road, we service it. We never push a hardware replacement when a rekey of the existing cylinder does the job.
Common Rekey Locks Problems We See in Covina Homes
- Pre-1960 mortise locks near downtown. Houses off Citrus Avenue and around the old Covina core often still carry original mortise locks or early pin-and-tumbler cylinders. These need the cylinder pulled and the worn plug cleaned before a standard pin kit seats correctly, which a lazy phone quote will miss.
- Builder-grade deadbolts in the northern tracts. The 1980s to 2000s homes up toward the hills off Grand Avenue are mostly Kwikset and Schlage deadbolts that rekey fast with a standard cylinder follower. The failure mode here is rekeying only one or two doors and leaving a garage entry or side gate on old keys.
- Paying for new hardware when a rekey would fix it. Some Covina homeowners get quoted a full deadbolt replacement when the existing ANSI Grade 1 deadbolt just needs its cylinder re-pinned. Rekeying stops the old keys for a fraction of the cost of new hardware.
- Old keys still circulating after a partial job. A house off Rowland Avenue with a back door, garage entry, and side gate left on the previous keys isn’t key control no matter how many front deadbolts were swapped. We check every keyed entry and tell you if any cylinder still takes the old key.
Pricing for Rekey Locks in Covina, CA
A standard pin-and-tumbler cylinder rekey in Covina runs $25 to $45 per cylinder, and a full house with three to four exterior doors falls between $75 and $180. Pre-1960 mortise locks and high-security cylinders from Medeco, Mul-T-Lock, or Baldwin can push the per-cylinder price to $45 to $75 because they need matched security pins or a dedicated rekey kit. The quote is scoped on the phone by asking your home’s build era and lock types, so the written price you agree to before dispatch is the price on the invoice. Call (409) 405-4485 for a free estimate. No call-out surcharge gets added when we arrive, and our Rekey Locks team in Covina confirms everything in writing before work starts.

FAQs About Rekey Locks in Covina
Most Covina homes with standard Kwikset or Schlage deadbolts take 30 to 60 minutes once our tech arrives, including verifying the cylinders work and handing you the old pins. Pre-1960 mortise locks near downtown add time because the cylinder must be pulled and the worn plug cleaned before re-pinning. We show up with a live trackable arrival time, so you’ll know exactly when we’re pulling up. Call (409) 405-4485 for a quote and time estimate for your specific home.
Yes, in almost every case. Rekeying replaces the internal pins and springs inside the existing cylinder, so the old keys stop working while your existing hardware stays in place. The only time replacement makes sense is when the cylinder is physically damaged, the keyway is too worn to seat new pins, or you want to upgrade to a higher-security lock. We’ll tell you which situation applies before doing any work, and the price stays whatever was agreed in writing beforehand.
Ask for the price per cylinder in writing before dispatch, whether it includes all exterior doors, and whether the price on the phone is the final invoice amount. Ask if the tech is background-checked and in uniform, and whether they’ll provide before-and-after photos. Our answer to all of those questions: yes, and the written price is locked before we roll. Call (409) 405-4485 and we’ll walk through the scope of your rekey.
You do need to be home, and we verify you have lawful access before touching any lock. For rental properties we ask for the lease or written authorization from the property owner. For a new home purchase we ask for something showing you closed, like escrow paperwork or a utility bill in your name. It’s a quick check that protects everyone, and it’s done before any cylinder is pulled.
Yes, that’s the default outcome of a whole-house rekey. We re-pin every exterior cylinder to the same new key so one key operates every door, the garage entry, and the side gate if it’s keyed. Some older mortise locks need a cylinder swap to join the same key system, and we’ll tell you if that applies to your Covina home before quoting. Call (409) 405-4485 to scope your doors and get a written price.
