Lock Rekeying in Jacksonville

Rekeying keeps your existing locks and retires every old key. 904 Locksmiths rekeys Jacksonville homes and businesses on-site, with new keys cut before the technician leaves. Call (904) 447-5436 to book a visit.

• Each cylinder removed, repinned to a fresh key cut, and reinstalled in its own door.
• Old keys checked against every rekeyed lock to prove they’re dead.
• New keys cut on the van and tested in every door they should open.
• Worn cylinders flagged honestly when repinning won’t save them.

Rekey work stretches from Fort Caroline and Monument Road houses out to newer builds near Girvin. Closings, new tenants, and contractors wrapping up a job drive most of it; the visit is the same either way, and it ends with one working set of keys.

What Rekeying Actually Does Inside the Lock

Every pin-and-tumbler cylinder holds a stack of pins sized to one key. Rekeying pulls the cylinder, follows the plug out with a follower tool, and replaces those pins with a new stack sized to a new cut, straight out of the pinning kit on the van. The old key stops lining the pins up at the shear line, so it stops turning anything, permanently. Nothing about the door, the latch, or the finish changes, which is exactly why rekeying costs less than new hardware.

Locks That Rekey and Locks That Argue

Conventional Kwikset and Schlage cylinders are the everyday case and go quickly. Kwikset SmartKey hardware rekeys with its own tool in minutes when the mechanism is healthy. Mortise cylinders in older Jacksonville houses and storefronts come out on a set screw and repin like anything else. High-security cylinders with restricted keyways can usually be rekeyed too, though their blanks are controlled, so key copies run through authorized channels rather than a hardware-store kiosk.

What Moves the Price

Cylinder count is the main dial. After that: mixed brands that need a cylinder swapped to reach one keyway, master-key layering for landlords who want an owner key over tenant keys, and cylinders worn far enough that they need service before they’ll hold a new pin stack. Timing plays its usual role. The number gets agreed on the phone, and it covers the keys cut at the end.

Does rekeying weaken the lock?

No. Fresh pins in a cleaned cylinder usually leave the lock crisper than it was, because years of grit and wear come out with the old stack. Security is unchanged or better; the only thing that dies is the old key.

We manage rentals. Can rekeys be standing work?

Yes, and it’s common. Turnover rekeys with keys handed to the manager, an owner key that survives every tenant change, and documentation of which cut went where make property turnover a routine call instead of a scramble. One phone call per unit, no meetings required. The same arrangement covers the harder days too: post-eviction rekeys happen once the legal process is complete and the unit is lawfully yours again, scheduled fast because that’s precisely when the old keys matter most.

Keyed-Alike vs Master-Keyed: Which One Do You Want?

They solve different problems and get confused constantly. Keyed alike means several locks share one identical key, which is what most households want: one key, every door. Master keying means each lock has its own key and a master opens them all, which is what landlords and small buildings want: tenants isolated, owner unrestricted. Keyed alike is a pinning choice; master keying is a designed system with a chart. A rekey visit can produce either, but knowing which you’re asking for keeps the quote and the outcome honest.

When Rekeying Isn’t the Answer

Hardware that’s physically worn out, a latch that no longer throws, or a door being upgraded anyway all point to replacement instead, and the technician will say so at the door. The same goes for the move to a keypad: if the real goal is to stop carrying keys, a rekey only postpones the decision.
