Lock Rekeying in Fontainebleau

If any neighborhood in Miami-Dade is defined by rekeying, it is this one. Fontainebleau holds 59,870 residents across 3.96 square miles of dense low-rise condominium and garden-apartment housing, built out from the 1970s as a set of subdivided villages. Roughly half the housing is renter-occupied, and the proximity of Florida International University's campus at 11200 SW 8th Street and its Engineering Center at 10555 West Flagler Street drives a fast-cycling student and young-professional rental population.

Short leases, frequent move-ins, lost keys and landlords who need documented rekeys between tenants add up to one thing: unit turnover rekeying is the single largest recurring job type in this community. It is not an occasional service here, it is the baseline of the work, and doing it correctly means doing it inside the building's existing key system rather than around it.

What Rekeying Does

A pin tumbler cylinder holds a row of chambers, each containing a spring, a driver pin and a bottom pin whose length matches one cut depth on the key. The correct key raises every bottom pin so the gap between bottom pin and driver sits exactly at the shear line between the rotating plug and the fixed housing, and the plug turns. Any other key leaves at least one pin crossing that line and nothing moves.

Rekeying removes the plug, takes out the existing bottom pins and installs a set matched to a different key. Springs and drivers generally stay. The lock body, strike, screws and finish remain exactly as they were, the door is untouched, and every copy of the old key stops working the instant the plug goes back in. On a unit that turns over annually, the whole operation is measured in minutes once the hardware and the system are understood.

Turnover Rekeying as the Core Job

When a tenant leaves, whatever keys they had cut during the tenancy go with them, and nobody has a reliable count. With short leases, roommate arrangements and mid-year moves, a unit here can pass through several people in a single year, each of whom may have made a copy for convenience. The only honest position for an owner is that an unrekeyed unit has an unknown number of keys.

Treating a rekey as a fixed step in the turnover, alongside cleaning and painting, removes the question entirely. It is quick, it costs a fraction of replacing hardware, and it leaves the door exactly as it was. The step most owners skip is the record: the date, the unit, how many keys were issued and to whom. For a landlord who needs documented rekeys between tenants, that note is the whole point of doing it, and it takes half a minute. There is a second reason to do it on a schedule rather than on suspicion. A rekey performed as routine takes minutes and is planned around the unit being empty between tenants. A rekey performed urgently, after a key has gone missing while somebody is living there, costs more and happens at a worse time.

Staying Inside the Building Master System

Most of these buildings run a master key system with a management-held master. A master system adds a second shear point in each chamber by stacking a master wafer between the bottom pin and the driver, so two different keys can both align the stack. A unit rekey inside that structure means choosing new bottom pin and wafer heights that produce the new change key while still allowing the master to operate.

Get it wrong and there are two failure modes, both bad. Lock the master out of a unit, which is a management and emergency access problem and in a rental removes access the landlord is entitled to. Or create unintended key combinations that open doors nobody authorized. This is why a rekey here starts with the system chart rather than with a pinning kit, and why fitting an unrelated hardware store lock silently breaks something nobody will notice until it matters.

Rated Corridor Doors and What Rekeying Avoids

Where a unit door opens onto an enclosed corridor or interior stair, the assembly is usually rated, which means it has to be self-closing and positive-latching, closing and latching on its own from any position. Hardware changes on a rated assembly carry real constraints, because a lock that is not part of the listing, or a change that stops the door latching on its own, compromises the rating.

Rekeying sidesteps all of it. Re-pinning a cylinder changes nothing about the assembly: nothing is unbolted, nothing is substituted, and the door closes and latches exactly as before. That is another reason rekeying rather than replacing is the right default on these doors. Where a cylinder genuinely must be replaced, the correct replacement is one on the building's keyway that suits the existing lock case, not a different lock with a different footprint. There is a related point about hardware selection. Where a rated door genuinely needs a new lock, the replacement has to suit both the listing and the building keyway, which makes it a specification exercise rather than a purchase. Getting that wrong means removing and replacing the same lock twice.

Interconnected Locksets and What Not to Change

Many unit doors here carry interconnected locksets, where turning the interior lever retracts both the latch and the deadbolt in a single motion. That exists so an occupant can always leave without unlocking anything first, and it is a life safety function rather than a convenience feature. It should never be defeated, disabled or replaced with something that requires two separate actions to exit.

During a rekey, the cylinder in an interconnected set is re-pinned like any other and the interconnection is unaffected. Where one of these is being replaced because the mechanism has genuinely failed, the replacement should be an interconnected set of the same configuration rather than a separate knob and deadbolt, because the footprint, the door prep and the egress behavior all depend on it. It is a specification question and it is worth getting right.

Designing a System That Survives a Hundred Turnovers

For an owner or manager with a block of units in a fast-turnover community, the design matters more than any individual rekey. A properly planned system has unit change keys at the bottom, building or section masters above, a management key at the top, and a separate branch for laundry, storage, mechanical and telecom spaces so a common-area key cannot be extended into a residence.

It also reserves pin segments so future units and future rekeys do not collide with existing keys. This is the part that gets skipped when a system is built one turnover at a time at the door, and the consequence shows up years later as a master that opens an unpredictable subset of doors and a drawer of keys nobody can match to anything. Rebuilding that starts with an audit: what keyway each cylinder is on and what the master actually opens today.

Mailboxes, Storage Rooms and Village Gates

Beyond the unit doors sits a large population of small hardware that nobody manages as a system. Mailbox banks with cam locks and a management access panel. Storage rooms, laundry rooms, bicycle storage, electrical and telecom closets, trash areas. Pool gates and clubhouse doors. Gated vehicle and pedestrian entrances with their own latches, locks and operators.

The failures are consistent: a mailbox cam lock whose key went with a tenant two years ago, a storage room opened by a key nobody can identify, a pedestrian gate whose latch no longer aligns because the gate has sagged. Bringing this under control as a single project is far more efficient than a year of small emergencies. Rekey the cam locks onto a controlled key, put storage on a defined branch, and record what exists. Pool gate hardware must keep closing and latching on its own.

Single-Family Houses and Townhomes

The villages also contain single-family houses, garden homes and townhomes, and those rekey more conventionally. There is usually no building master to work around, so the sensible target is a single key covering the front door, any rear or side door, the passage door from the garage into the house, and the garage service door. Keying alike achieves that in one visit and removes a whole class of minor lockout.

Two things are worth doing at the same visit. Check that the passage door from the garage into the house actually has a deadbolt rather than just a knob lock, because on most of these houses that opening is the weakest one and it is the cheapest to improve. And confirm that any keypad on the exterior of the overhead garage door is not still running the code a previous occupant or a contractor set, since codes and keys are separate systems. It is also worth checking the exterior side service door into the garage, since those are frequently fitted with the lowest grade hardware on the property and are often the last opening anybody thinks to include in a keying plan.

Controlling Duplication

A rekey retires every key that exists today. It does nothing about copies cut tomorrow, because standard keyways can be duplicated at any hardware counter or self-service machine by anyone holding a current key. In a community with this much turnover, that gap is the real exposure rather than the keys just retired, and it is exactly why some landlords find themselves rekeying the same unit twice in a year.

Restricted and patent-protected keyways close it by controlling the blanks, so copies are only produced through an authorized channel for someone on an authorization list. It costs more initially and it changes how tenants operate, since a copy is no longer something anyone can obtain casually. That is the point. For an owner it converts an unknown key count into a known one, which also makes the next rekey decision a matter of policy rather than guesswork.

Documenting Every Change

In a portfolio with constant turnover, undocumented rekeys become a problem quickly. Record the date, the unit, the keyway, the pinning, how many keys were cut and who received each one. For a landlord this is the difference between knowing that a unit was rekeyed at the last turnover with two keys issued, and guessing, and it is the document that answers a dispute about access after the fact.

Keep the master system chart somewhere safe and off the property. A system whose chart has been lost has to be rebuilt from scratch, which across a block of units means touching every cylinder. Keep a note of the hardware on each unit door so a replacement cylinder can be specified without a site visit. None of it takes long at the time, and all of it saves money the next time somebody needs a key cut in a hurry.

Preparing Your Keys and Hardware List Before the Visit

A few minutes of preparation can make a rekey in a condo or townhome noticeably smoother. Start by gathering every key you have to the unit: the main door key, any secondary lock keys, mailbox keys if they are yours to manage, and any spares kept with relatives or neighbors. Lay them out and look for stamps or marks. Having this information on hand makes every later decision about the property simpler. A key stamped do not duplicate may be a restricted type, and that detail changes the options.

Next, check what each door has. Take a quick photo of the entry hardware from inside and outside, including the brand name on the cylinder if it is visible. Note whether the door has both a knob or lever and a separate deadbolt, and whether both turn with the same key today. If you are unsure about any step, pause and ask before the work continues. If the building has rules about door appearance, hardware changes or contractor access, find them in your association documents and keep a copy handy for the technician.

Finally, decide how many keys you want after the work and who will hold them. Name them if you can, since knowing the holders makes the key count easy to settle. Tell the technician about any electronic parts, such as a keypad or fob reader on the door, so the rekey does not interfere with them. The scope and any quote are explained before work begins, and the new keys are tested in the lock before the technician leaves. Good habits at this stage pay off for years afterward with very little effort. Call us to confirm availability.
