Fast, Reliable Rekey Locks Across South Miami
Rekeying a lock in South Miami typically runs $20 to $55 per cylinder for standard Schlage and Kwikset hardware, with the full price written down before anyone leaves our shop. We serve every South Miami neighborhood, from the ranch houses off Ludlam Road to the newer builds near Dante Fascell Park, and we answer the phone with a live person around the clock. That matters in a city where half the calls we get come from new owners standing in an empty house on closing day, holding a key ring they don’t trust. Call (409) 405-4485 and you’ll get a real price, not a teaser.
Why Preston Locksmith & Security Is South Miami’s Preferred Rekey Locks Company
We’re the Rekey Locks crew that South Miami property managers call when key control actually matters. Every technician is background-checked, arrives in uniform, and carries a company ID next to a state locksmith license. Before we touch a single screw, you get a written price and a live arrival time you can track on your phone. The Relay Visibility Guarantee means you’ll also get before-and-after photos of the work and a digital invoice with a pay link. No anonymous van, no mystery technician, no number that changes at the door.
Most South Miami rekey jobs are done in under an hour, and the price we quote on the phone is the price on the invoice. Kevin Yoon, who leads our operation, set that standard because he saw too many homeowners burned by quote-and-switch pricing in this market. We’ve been doing it this way since 2008.
Keyed Alike in South Miami
Keyed Alike in South Miami means every lock you choose works from one key. We physically remove each cylinder, swap the internal pins to match a single key code, and test each lock from both sides before we leave. For a typical South Miami home with a front door deadbolt, a back door, and a side gate, this runs $95 to $180 total depending on how many cylinders are involved.
What the Job Involves
We pull each cylinder, decode the existing pin stack, and repin it so one key operates all of them. The old keys stop working immediately. No new hardware is required unless the cylinder itself is worn past the point of reliable operation, which we see often on 1950s mortise locks in South Miami.
When Homeowners Ask for It
The most common trigger is a closing. You bought a house in South Miami and you have no idea who still holds copies of the old keys. Keying everything alike on one Kwikset KW1 or Schlage SC1 key is the fastest way to restore key control without replacing hardware that still works fine.
Rekey Deadbolt in South Miami
Rekey Deadbolt in South Miami runs $25 to $45 per deadbolt for standard Schlage, Kwikset, or Yale hardware, and the work usually takes 15 to 20 minutes per lock. We repin the existing cylinder so the old keys stop turning and the new key operates the deadbolt.
Single Deadbolt vs. Whole-Home Rekey
A single deadbolt rekey makes sense when you’ve lost one key and don’t want the old one floating around. A whole-home rekey covers every exterior entry point, and in South Miami that should include the deadbolts, the entry knobs, garage side doors, and any gate locks the previous occupant might have had keyed separately.
What We Check While We’re In There
When we pull a South Miami deadbolt apart, we check the strike plate screws, the bolt throw, and the tailpiece for wear. Older homes off Red Road and Sunset Drive frequently have strike plates screwed only into the door frame, not the stud behind it. We’ll rekey the cylinder and flag that issue for you, with a written recommendation and a price for the fix if you want it done that day.
Trusted Brands We Service in South Miami
We rekey and service Medeco, Schlage, Kwikset, and Abloy hardware across South Miami. Our vans carry common pin kits and cylinder parts for these brands, so a rekey job on a Schlage deadbolt near South Miami Middle School doesn’t turn into a two-trip job. If you have high-security Medeco cylinders, bring the card that came with the locks; that card controls who can legally order your key blanks, and we’ll verify it before we cut anything.
Common Rekey Locks Problems We See in South Miami Homes
- 1950s mortise locks with worn pin stacks. Many South Miami homes built in the 1940s and 1950s still carry original mortise lock bodies in solid wood doors. A standard modern pin kit doesn’t always drop in cleanly; the cylinder often needs fitting and adjustment before the rekey will hold.
- Partial rekeys that leave the back slider on the old key. We see this on South Miami rentals all the time: someone rekeyed the front door but left the back slider and side gate on the tenant’s old key. Key control was never actually achieved.
- Doorstep price changes on older hardware. A phone quote that assumes a modern Schlage or Kwikset cylinder becomes a bigger number when the tech opens the door and finds a 1950s mortise lock that needs different pins and springs. Our written quote accounts for what’s actually in the door before we dispatch.
- No proof of identity from the tech. In South Miami, a huge share of rekey calls come from new owners and property managers who have never met the crew before. If the person at your door can’t show a state locksmith license and a company ID, that’s a problem. Our techs always carry both.

FAQs About Rekey Locks in South Miami
We rekey the original mortise locks. We carry pin and spring kits sized for 1940s and 1950s cylinders and we’ll fit the lock back into the original door rather than pushing a replacement that changes the look of your hardware. If the cylinder is genuinely beyond repair, we’ll show you why and give you a written price for both options. Call (409) 405-4485 and we’ll quote it honestly before we dispatch.
Yes. We repin each cylinder to a single key code so one key operates the front deadbolt, back door, and side gate. This is the most common request we get from South Miami buyers on closing day, and it runs $95 to $180 for a typical three-point setup. The exact figure depends on the cylinder types involved, and we’ll confirm the number on the phone before a tech is dispatched.
Every tech carries a state-issued locksmith license and a Preston Locksmith & Security company ID. They arrive in uniform, in a marked vehicle, and your live tracking link will show their arrival time before they knock. Kevin Yoon’s team has run this way since 2008, and we’ll never send someone who can’t prove who they are at your South Miami door.
Yes, as long as the cylinders and housings are in working condition. Rekeying swaps the internal pins so old keys stop working. The physical lock body stays the same, so the security level is unchanged from the original hardware. If your South Miami deadbolt is worn, rusted from humidity, or has a loose strike plate, we’ll flag it and quote the fix separately, in writing.
Most rekey jobs take 30 to 60 minutes for a standard South Miami home with two or three exterior locks. Mortise locks on older homes can add 10 to 15 minutes per lock because we fit and adjust the cylinder rather than just swapping pins. We’ll give you a time estimate when we quote the price, and you can track our arrival in real time. Call (409) 405-4485 for an exact quote, free.
