Is it the lock or the rollers?

Often the rollers. When a panel sags on worn rollers, the latch drops below the keeper and the lock stops catching even though nothing inside it is broken. The technician checks panel height before condemning the lock.

Does salt air really reach my house if I am not at the beach?

Yes. Salt off the Atlantic and the tidal St. Johns River shortens the life of exterior hardware well inland in Jacksonville. It corrodes the lock spring and the keeper along with rollers and tracks.

Do I need a permit for a lock or handle repair in Jacksonville?

Like-for-like repairs such as roller, track, handle or lock replacement normally require no permit in Florida. Replacing the whole sliding door unit or altering the opening usually does. Check with the Jacksonville or county building department for your specific address.

Can a lock be matched to an older aluminum slider?

Mortise locks, keyed locks and handle sets are matched to the door's make, and older single-pane aluminum sliders are still widely in service across Florida. The technician identifies what the door takes when he looks at it.

Lock or handle in Jacksonville, FL

You turn the handle and nothing catches. Or the handle swings loose in your hand and the latch never reaches the keeper. Most of the time the lock itself is not the problem. The panel has dropped a little on worn rollers, so the latch no longer lines up with the hole it is supposed to drop into. That is why rollers get checked first on a lock call. The other thing to know: forcing the handle to make a stubborn lock catch is what breaks the lock body inside the stile, and then you are replacing more than you started with.

Jacksonville is hard on this hardware. Salt-laden air off the Atlantic and the tidal St. Johns River corrodes the lock spring and the keeper, and it does that well inland, not just at the beaches. Year-round humidity keeps steel rollers and bearings rusting and pits aluminum tracks and sills. Blown sand, grit and heavy spring pollen pack the track and grind rollers flat, which is exactly how a panel sags out of alignment. Florida homes often have two or more sliders onto a patio, screened lanai or pool deck, and older single-pane aluminum sliders are still in service all over town.

While you wait — please don't

Stop forcing the handle. Levering hard on a latch that will not reach the keeper breaks the lock body inside the stile and turns a small repair into a bigger one.
Do not leave it unlocked and hope. A patio door that cannot be locked is an open door, so treat it as something to get fixed rather than live with.
Do not lift the panel out yourself. A sliding glass panel weighs as much as a person and shatters into the room if it slips; if the glass is cracked or the panel is off its track, stop using the door and leave it to the technician.
Do not pack the lock with grease. Heavy grease holds the blown sand, grit and pollen that are already working into the track, and the lock gets stiffer rather than freer.

What the technician does

The rollers get checked firstThe technician looks at whether the panel has sagged on worn rollers before touching the lock. A lock that stopped catching is often a height problem, not a broken lock.
Roller height adjustedWhere the latch no longer lines up with the keeper, the roller height is adjusted to bring the panel back up. Sometimes that alone fixes the catch.
Keeper realigned or replacedThe latch keeper in the jamb is shifted back into line, or swapped out if it is corroded or chewed up.
Lock and handle set matched to the doorMortise locks, keyed locks and handle sets are matched to the door's make. A flopping handle usually comes off with the old lock body.
Secondary locks and foot boltsIf the door needs to stay secure, secondary locks and foot bolts can be fitted. Ask the technician to show you the worn roller or lock body and to put the reasoning in writing.
Free estimate firstThe technician looks at the door and gives you the price before any work starts. You approve it first.

Why this happens in Jacksonville, FL

Jacksonville runs very different housing stock inside one city. Riverside, Avondale, Ortega and Springfield hold early-1900s wood-frame and brick homes; Mandarin, Southside, Baymeadows, Arlington and Bartram Park lean toward 1990s-and-newer stucco and block subdivisions, often inside HOA or gated communities. The sliders are different ages and different makes, which is why lock bodies and handle sets get matched to the door rather than guessed at. Along the beaches and the river, condo balcony sliders take the worst of the salt air.

Timing matters too. Problems climb through the summer rainy season and the June-to-November hurricane season, when wind-driven rain hits the sill and people start checking whether every opening actually locks. Spring pollen and blown coastal sand bring a second wave, because that is what packs the track and wears the rollers that hold your panel at the right height. Northeast Florida also sees several freezes and the occasional hard freeze each winter, which stiffens lubricant-starved door mechanisms. Like-for-like repairs — rollers, handles, locks, keepers — normally need no permit in Florida, but replacing a whole sliding door unit typically does, along with a product carrying current Florida Product Approval. Your local building department can confirm what applies at your address.
