The Crestview Landlord's Guide to Rekeying Between Tenants
By the Crestview Locksmith team · 2026-07-18
The Reality of Key Control in a Military Town
Living in the shadow of Eglin and Hurlburt Field defines our rental market. We have a high volume of tenants who move frequently, often on government orders with tight timelines. This transient nature creates a specific risk for landlords regarding key control. A key handed to a relative three years ago before a deployment to the Middle East could still be floating around a neighborhood in Crestview long after that tenant has moved to a new duty station in another state.
Real security means treating physical keys like ammunition: you must account for every round. When a tenant moves out, you have zero confirmed knowledge of how many keys exist for that lock. They might have kept a spare for a neighbor, lost one at a park in Bluewater Bay, or had one cut at the local hardware store without your permission. Rekeying resets the lock mechanism so that the old keys operate like pieces of scrap metal and only the new key works. It is the only way to guarantee that the new tenant holds the exclusive power of access. In this market, asserting control over your keys is as important as asserting control over your lease terms.
Why Coastal Humidity Kills Locks (and When to Replace)
Rekeying is the standard for turnover, but living on the Gulf Coast introduces a mechanical enemy that plain rekeying doesn't fix: corrosion. The humidity in Crestview and the salt air coming in from the coast are brutal on the internal brass pins of a lock cylinder. I frequently open doors in older developments near downtown Crestview or in the outlying rural areas where the internal mechanism looks like it has been submerged in saltwater.
If you simply rekey a lock that has already begun to corrode, you are putting fresh pins into a corroded shell. The result is a lock that works perfectly for the technician on a sunny Tuesday but sticks or jams completely for the new tenant on the first humid morning. The binding caused by rust on the plug or the tailpiece can render the new key ineffective. My rule of thumb for landlords in the Panhandle is this: if the lock is more than five years old and shows signs of pitting or stiffness, replace it rather than rekey it. The cost of a new residential grade lock is negligible compared to the emergency service call required to unlock a door for a frustrated tenant at 2:00 AM because a corroded cylinder seized up.
The Process: What Actually Happens During a Service Call
Understanding the mechanics helps you manage your properties better. When we rekey a lock, we are not changing the hardware visible on the door—the knob or the deadbolt stays in place. We remove the cylinder from the housing, strip out the existing bottom pins, and replace them with new pins of varying heights that correspond to a completely different key cut.
For landlords managing multiple units, this is the time to consider a "keyed-alike" system. If you own a duplex or a small apartment complex, having a single master key that opens all units while individual tenants have keys that only open their specific unit is a massive efficiency booster. However, be warned: master keying requires slightly more complex pinning stacks, which can make the lock slightly more sensitive to wear and tear. If you choose this route, invest in higher-quality locks with tighter tolerances. Cheap locks with master systems tend to fail faster, especially when subjected to the heavy use common in rental properties.
Smart Locks and the Modern Rental
We are seeing a massive shift in Crestview vacation rentals and long-term leases toward electronic smart locks. This technology solves the physical key problem entirely. You can issue a temporary code to a tenant that expires the moment their lease does, or generate a code for a cleaning crew that works only on Tuesdays.
However, do not assume "smart" means "maintenance-free." The batteries in these units drain faster in temperature extremes, and our summer heat can be brutal on electronics. Furthermore, the smart features on many retail-grade locks are housed in the exterior escutcheon, making them vulnerable to being stripped off by a determined thief with a screwdriver. If you go this route, buy commercial-grade hardware where the electronics are internal or protected by a reinforced shroud. A smart lock that fails because of a dead battery or a cracked circuit board leaves your tenant locked out just as surely as a rusted mechanical lock, but it requires a much more expensive fix.

Is it cheaper to rekey or replace locks?
Rekeying is generally less expensive because you are only paying for the labor and a small kit of pins rather than new hardware. However, if the existing lock mechanism is damaged by our coastal humidity or age, replacement is the more cost-effective long-term solution.
Can I rekey my own rental property locks?
You can buy rekeying kits at hardware stores, but without the training, it is easy to pin a cylinder poorly, causing the lock to stick or fail entirely. For a liability-critical asset like a rental, a professional ensures the job is done right the first time.
How long does a rekeying service take?
A standard rekey on a single deadbolt or knob usually takes about ten to fifteen minutes per door once the technician is on-site. If you are managing a large property with multiple doors, plan for the service to take an hour or more to account for travel and setup.
