Why Dunmore Locksmith Is Three Lakes’s Preferred Change Door Locks Company
The security concern in Three Lakes isn’t abstract. Homeowners here protect their front doors with rejas, impact-rated steel, and multi-point hardware because they understand what a weak entry point costs. So do we. That’s why the Change Door Locks team at Dunmore Locksmith carries parts for Medeco, Schlage, and Kwikset hardware plus the rim locks, surface bolts, and specialty handle sets common on Miami-Dade iron gates.
Perry Osgood leads the team, and the standard he set is simple: every technician is background-checked, identity-verified, and sent to your phone with a name and photo before they ever pull up to your house. The technician arriving at your Three Lakes door wears a clean uniform and carries a photo ID badge shown at the door before any work begins. If someone shows up who wasn’t announced, that visit is covered at no charge. We don’t leave room for guessing who’s at your door.
Phones are answered by a live person 24/7, not a voicemail tree or chatbot. That matters at 2 a.m. when the deadbolt won’t throw and you can’t lock up. It matters at noon when a tenant just left and you need the locks changed before evening. A real human picks up every time.
Lock Change in Three Lakes
Lock Change in Three Lakes means replacing the hardware that secures a door, and on most homes here that means addressing at least two points of entry: the main entry deadbolt and, in many cases, the rim lock or surface-mounted bolt on the wrought-iron reja out front. Homeowners call for a lock change after a break-in or attempted break-in, when keys are lost or unreturned, after divorce or roommate changes, or when storm damage has compromised the existing hardware. A straightforward lock change on a standard door in Three Lakes typically runs $95 to $180. When the job includes an impact-rated steel door with multi-point hardware, expect $180 to $260 because the lock body, strike plate, and frame alignment all have to be addressed together.
What Actually Gets Replaced
We remove the old deadbolt or knob assembly, check the condition of the bore and strike plate, and install new hardware that matches your door prep. On Three Lakes homes the bore is often through steel or iron, not standard wood, which means the installation has to account for thicker door slabs and reinforced frames. We carry longer tailpieces and strike plates sized for post-Andrew doors so the lock engages cleanly on the first throw.
When the Reja Gate Has to Be Included
Changing only the front door deadbolt while leaving the reja rim lock on an old key is a real problem here. Whoever holds that old key can still open the gate. We service the gate lock in the same visit: replace or rekey the rim cylinder, check the surface-mounted bolts for corrosion, and make sure the gate closes tight against its frame. That’s the difference between a partial fix and a property that’s actually re-secured.
Change Lock Cylinder in Three Lakes
Change Lock Cylinder in Three Lakes is the more surgical job: replacing just the internal cylinder where the key inserts, without removing the full lock body. It’s the right call when the lock hardware itself is still in good shape but the key turns rough, sticks, or the cylinder has seized from South Florida corrosion. In Three Lakes, a lock cylinder change on a standard deadbolt runs $65 to $120. For high-security cylinders from Medeco or Schlage, the price runs $110 to $180 including keying to your existing or new key.
Cylinder Corrosion From Humidity and Salt Air
The humidity here isn’t a minor inconvenience for lock hardware. Brass and zinc cylinders absorb moisture year-round, and the salt content in the air accelerates internal corrosion. A cylinder that works through the dry season can bind badly by August. When we replace a cylinder in Three Lakes, we use sealed or marine-grade components where available and apply a dry lubricant that doesn’t attract the grit that seizes pins.
Re-Keying as the Lower-Cost Option
Re-keying means changing the internal pins so your old keys no longer turn the lock. It costs less than a full cylinder replacement, usually $45 to $85 per lock in Three Lakes. If the cylinder itself is sound, re-keying is the smarter spend. If it’s corroded or starting to bind, we tell you plainly and recommend replacement instead of a re-key that would fail within a season.
Trusted Brands We Service in Three Lakes
We’re factory-authorized to install and service Schlage, Kwikset, Medeco, plus Abloy and Mul-T-Lock hardware on both residential and commercial jobs. Three Lakes homes carry a mix of standard residential brands and higher-security hardware installed during post-Andrew rebuilds. We stock common cylinders, tailpieces, and strike plates for those brands locally, so most lock changes and cylinder swaps happen in one trip. If your door has proprietary multi-point hardware from a European or high-security line, we can usually source the parts within 24 hours and return to finish the job at the original written price.
Common Change Door Locks Problems We See in Three Lakes Homes
- Post-Andrew steel doors with proprietary multi-point hardware. Miami-Dade’s wind-load codes after Hurricane Andrew pushed builders toward impact-rated steel entry doors with locking systems you won’t find at a big-box hardware store. A locksmith carrying only standard Kwikset or Schlage parts will be stuck on a large share of Three Lakes lock calls. We carry the extended locks, strike plates, and tailpieces those doors require.
- Wrought-iron reja gates left on old keys. Homeowners often change the front door lock after a tenant or service provider leaves, but the gate out front still opens with the old key. If anyone still holds that key, the home isn’t secure. Every lock change here includes a check of the reja rim lock and surface-mounted bolts.
- Deadbolts binding in wet-season frame shifts. Concrete-block frames in South Florida move slightly as the ground swells and contracts through the wet season. A deadbolt that threw cleanly in March can bind hard by July. Installing a new cylinder without adjusting the strike plate and frame alignment means the problem returns. We adjust the frame as part of the lock change, not as an add-on surprise.
- Corroded cylinders from year-round humidity. Brass and zinc lock cylinders in Three Lakes fail faster than they would in a drier climate. Frequent symptoms: a key that turns hard, sticks mid-turn, or won’t insert fully. We see it most often on reja gate rim locks, which take direct exposure to rain and sun, and on entry deadbolts soaked by afternoon thunderstorms.

FAQs About Change Door Locks in Three Lakes
My Three Lakes home has a steel impact door from a post-Andrew rebuild – can you still change the locks?
Yes. We stock extended tailpieces, reinforced strike plates, and multi-point lock components sized for post-Andrew impact-rated steel doors. A standard deadbolt swap won’t fit most of these doors correctly, and we don’t force one in. We measure the door thickness and existing prep, then install hardware that engages cleanly without binding. The price runs $180 to $260 for a full lock change on these doors. Call (910) 714-4287 for an exact number before you book.
Does changing my door locks in Three Lakes include the wrought-iron gate (reja) out front?
Yes, and we recommend you include it. The reja gate has its own rim lock and surface-mounted bolts, and if you only change the front door deadbolt, the gate still opens with the old key. On a lock change visit we either re-key or replace the gate rim cylinder so the whole property goes onto one new key. Cost for the gate lock service runs $45 to $120 depending on whether it’s a re-key or cylinder replacement. We’ll quote it before starting.
Why does my deadbolt keep binding in the wet season here?
South Florida’s wet season saturates the soil, and the concrete-block door frames in Three Lakes shift enough to misalign the strike plate and make the deadbolt bolt bind. Installing a new lock cylinder alone won’t fix that, because the frame is the actual problem. During a lock change, we check and adjust the strike plate position and tighten the frame hardware so the lock throws cleanly. If it binds again within 365 days, the Done Right Promise means we return free.
Can you avoid drilling my lock during a Three Lakes lock change?
In most cases, yes. If you still have the working key, the lock can be removed and replaced without drilling. Even when the cylinder is seized or the key is lost, we use non-destructive entry methods whenever possible. Drilling is a last resort, and if it becomes necessary we tell you before doing it and include any damage repair in the written price. On a recent post-storm call off the SW 56th Street corridor, we used non-destructive entry on a post-Andrew steel door with seized multi-point hardware, so the family didn’t lose a door they’d already rebuilt once.
What hardware holds up best in Three Lakes humidity – should I replace or re-key?
For humid, salt-adjacent climates like Three Lakes, high-security cylinders from Medeco or Schlage’s weather-resistant lines hold up better than budget brass cylinders, which corrode and seize within a few seasons. Whether you replace or re-key depends on the cylinder’s condition: if the key still turns cleanly, re-keying at $45 to $85 is the better value. If it sticks, binds, or shows visible corrosion, replacement at $65 to $180 saves you a second service call within the year. Call (910) 714-4287 and we’ll help you decide over the phone without a site visit.
