Rekey or Replace? How to Decide for Your Jacksonville Home

What rekeying actually is

Every pin-tumbler lock has a row of small pins inside the cylinder. Your key works because its cuts line up with those pins at exactly the right height. Rekeying means a locksmith removes the cylinder, swaps those pins for a new set, and cuts a new key to match. The lock body, the deadbolt, the handle and the strike plate on the door frame all stay exactly where they are.

The result is that every old key stops working immediately. It does not matter how many copies were made or who has them. The lock looks the same from the outside, works the same, and now answers only to the new key. Rekeying takes a few minutes per lock once the technician is at the door.

When rekeying is the right call

Rekeying is the default when the hardware is fine and the problem is who has a key. These are the common situations in Jacksonville homes.

In all of these cases the locks themselves are doing their job. Paying for new hardware would buy you nothing but a different finish. Rekeying gives you the security reset you actually need.

• You just bought or moved into a home. Previous owners, their relatives, contractors, cleaners and agents may all still have keys.
• You lost a key or had one stolen, especially along with anything that shows your address, like a wallet or a bag with mail in it.
• A tenant moved out and you are turning the unit over.
• A roommate, partner or ex moved out and did not return every key.
• A contractor or house sitter had a key for a project that is now finished.
• You have several locks that take different keys and want one key for the whole house.

When replacing the lock is the better choice

Sometimes the hardware is the problem, not the key. Replacement is the right move in these cases.

A locksmith can also mix and match on one visit: rekey the good locks, replace the tired ones, and key everything to a single key so you leave with one key that works at every door.

• The lock is worn, sticky, loose on the door, or the key has to be jiggled to turn. Rekeying a failing cylinder is a short-term fix.
• The lock or the door was damaged in a break-in or an attempted one.
• You only have a knob lock on an exterior door and want to add a real deadbolt. That is an upgrade, not a rekey.
• You want a smart lock with keypad codes, a phone app, or auto-lock.
• The existing lock is a light-duty builder model and you want a sturdier grade on a front or garage entry door.
• Your locks are a mix of brands with different keyways and you want them all keyed alike. Cylinders from different manufacturers usually cannot share a key, so one or more need replacing to match.

What each option costs, in plain terms

Rekeying is priced per cylinder plus the service call, so a house with four exterior locks is a known number before the technician leaves the shop. Every door done in one visit costs less per lock than coming back later, and keying them all to one key is part of the job, not an extra. Replacement adds the hardware: a builder-grade deadbolt is inexpensive, a Grade 1 deadbolt costs more, a smart lock more still, and bringing your own lock from the hardware store lowers the price.

Neither option should come with a surprise. Ask for the whole price on the phone, including the drive and the labor, and expect it to change only if the technician finds something different at the door, such as a lock that is already failing.

Lock grades, and what Grade 1 actually means

Residential locks are rated by ANSI and BHMA on a scale from Grade 3 to Grade 1. Grade 3 is the builder-grade hardware on most new Jacksonville homes: it works, but it is the minimum. Grade 2 is a solid step up. Grade 1 is the commercial standard, tested for far more cycles and impacts, and it is what to ask for on a front door if you are replacing anyway. The grade is printed on the box and often stamped inside the packaging.

The grade of the lock only matters if the door and frame hold. A Grade 1 deadbolt in a strike plate held by half-inch screws still fails at the frame. Any replacement is the moment to add a reinforced strike and three-inch screws into the framing, which costs little and does more for a kick-in than the lock itself.

Rekeying a Kwikset SmartKey versus a standard cylinder

If your locks have a small horizontal slot next to the keyway, they are Kwikset SmartKey and can be rekeyed in seconds with a reset tool and the new key, without taking the lock apart. Standard pin cylinders from Schlage, Baldwin and most other brands are rekeyed by removing the cylinder and swapping the pins, which takes a few more minutes per lock. Both are done at your door.

The one thing rekeying cannot do is make a Kwikset key work in a Schlage lock, because the keyways are different shapes. If your doors are a mix of brands and you want one key, the technician can swap cylinders so they match, which costs less than replacing whole locks.

Landlords and lock changes between tenants

Florida law does not set a rule that landlords must change or rekey locks between tenants. Even so, it is standard practice among landlords and property managers in Jacksonville, for a simple reason: you cannot know how many copies a former tenant made or handed out. Rekeying between tenants is inexpensive and quick, it protects the new tenant, and it protects you from the argument that a former tenant's key caused a loss.

Many landlords rekey at every turnover and keep a record of the date and the key code. If the property has several doors, keying them alike means one key for the tenant and one record for you. If your lease or your insurance carrier has any lock requirements, follow those. A rekey visit is also a good moment to check that strike plates are screwed firmly into the frame and that sliding doors have a secondary lock.

Keyed alike, smart locks, and what happens on the visit

Keyed alike means several locks are set up to take the same key. For a house that usually means the front door, back door, side door and garage entry all open with one key. A locksmith does this by pinning each cylinder to the same key cuts. Locks in the same brand family can be keyed alike easily; mismatched brands may need one cylinder swapped so it uses the same keyway.

If you are replacing anyway, a smart lock is worth a look. You can give codes to family or a cleaner and delete them later instead of rekeying again, get a phone alert when the door unlocks, and stop hiding a key under the mat. Most smart deadbolts still have a key cylinder as a backup, and that cylinder can often be keyed to match your other doors.

On the visit, the technician looks at each door, confirms what you want rekeyed versus replaced, and gives you a flat price before starting. Rekeying is done on the spot, and new keys are cut and tested in every lock before the technician leaves. For replacements, mention your preferred finish and style, or ask what is in stock; We Do Locksmith carries common residential hardware in the van and at the shop counter at 8727 Old Kings Rd S. Test every key at every door before you sign the invoice.

A five-minute checklist before you call

A little preparation turns the call into a precise quote and the visit into a single trip.

• Count every exterior door, including the garage side door and the door from the garage into the house
• Note the brand stamped on the latch edge of each lock; Kwikset and Schlage are the usual two
• Decide whether you want every door on one key, and whether the mailbox and gate should match
• Gather any old keys so the technician can check which locks they fit and which should be rekeyed
• For a rental, have the lease or a message from the landlord ready; for a new purchase, the closing paperwork
