What actually goes wrong with sliding door locks, from JDM elite technician Yuval.
About 10 to 20 percent of the time, a lock that will not catch is not actually broken.
The rest of the time, the lock mechanism itself has worn out and simply stops working, the latch will not throw or hold anymore.
Not always. About 10 to 20 percent of the time the lock is fine and the door has drifted out of alignment, so the latch no longer lines up with the keeper. We check alignment first and adjust it. If the mechanism itself is worn out, we replace it with the correct lock for your door.
The most common failure is the internal mechanism wearing out so the latch will not throw or hold. Before replacing anything, we confirm it is not simply an alignment issue, which accounts for 10 to 20 percent of lock calls. If it is the mechanism, we swap in the right lock and test it.
From Gal Cohen, Field Area Manager: "I have been on sliding door lock repair jobs since 2012, and our crews now run them across Florida, New York, Georgia, Colorado, Texas and South Carolina. Most repairs we handle wrap up in roughly 2 hours, same-day, and you can see the real before-and-afters in the photos and videos on this page."
JDM repairs sliding door locks that won't engage, feel loose, or take too much force to throw, restoring secure operation usually in a single visit. A lock that doesn't latch fully is a real security gap, and it only gets worse: daily use wears the internal parts, humidity corrodes the mechanism, and a settling frame pulls the lock out of alignment.
We start by inspecting the whole locking assembly, the latch, keeper, handle mechanism, and mounting hardware. We pinpoint the exact cause, whether that's worn internal parts, a misaligned strike, corrosion, or a mix, then fix that rather than guess. Getting the diagnosis right the first time saves you time and money.
Our techs carry a full inventory of lock parts for all major sliding door brands, so most repairs finish same day. We realign hardware, replace worn internal parts, reset keeper positions, and dial in the mechanism so it engages smoothly and holds. Every repair comes with upfront pricing, no hidden charges, and our satisfaction guarantee.
These two get described the same way on the phone, and they point at different parts.
A door that will not latch closes but the lock never catches. You throw the lever and it swings through with no resistance. Nine times out of ten the keeper, which is the metal plate on the fixed panel that the latch hooks into, has drifted out of position or the panel has settled a few millimeters. The latch is passing above or below the slot instead of into it.
A door that will not lock is the opposite. The lever will not move at all, or it moves partway and stops hard. That is inside the mortise lock body, the cartridge buried in the edge of the door. Internal springs break, the cam hook seizes, or corrosion binds the mechanism.
The reason it matters is cost. A keeper problem is an alignment fix and it is the cheaper visit. A seized mortise lock means the cartridge comes out and a new one goes in. Telling us which behavior you are seeing helps us bring the right parts.
There is no universal sliding door lock. The mortise cartridge is sized to the door it came in, and the wrong one will not seat.
We match on three measurements: the face plate length, the distance from the face plate to the center of the handle spindle, and the screw hole spacing. Andersen, Pella, PGT, Milgard and the older aluminum frames all use different combinations, and several changed their spec partway through a production run, so the year of the door matters as much as the brand.
If your door has no brand sticker left on the frame, the tech pulls the existing cartridge and measures it on site. We carry the common sizes on the truck. When a door uses a discontinued cartridge, which happens on aluminum frames from the seventies and eighties, we fit a current lock and adapt the mounting rather than telling you the door has to be replaced.
We would rather say this up front than after you have paid twice.
A lock repair holds when the door itself still runs true. If the panel rolls smoothly and sits square in the frame, resetting the keeper or replacing the cartridge fixes the problem for years.
It does not hold when the door has dropped. Worn rollers let the panel sag, the sag pulls the latch out of line with the keeper, and any alignment we do gets undone the next time the door settles. On those we replace the rollers first and then set the lock, because doing the lock alone means you call us back in a month.
A frame that has bent or a door that has racked out of square is the other case. There the lock is a symptom. We tell you what the frame needs and quote both parts so you can decide.
★★★★★ Verified Google Reviews ★★★★★ · a month ago"After I made an appointment I decided I was going to try and do it myself. Michael FaceTimed me, walked me through what to do, then call back if I still needed him. An hour later I called him and he was at my house in 35 minutes. Some of the best service I've ever received from a contractor. He finished in two hours and went above and beyond. The same-day service was incredible. Absolute professionals."
★★★★★ · a year ago"After a couple of hiccups with getting our repair done by someone else, our technician Richard showed up on time (actually half an hour earlier than the appointment time). He was very polite and got the job done in the time he told us it would take. Our glass door now glides smoothly and is able to lock again. I highly recommend Richard, he represented his company very well. I will definitely consider using them in the future!"
★★★★★ · 9 months ago"David, thank you so much for taking the time to explain everything to us. He was so patient, and I appreciate him doing a clean and awesome job. He was respectful of my home and cleaned up after the work was complete. Now my door slides like new, quiet, and smooth. Again, thank you David."

Lock won't catch? Ask us to check the alignment first.
About 1 in 5 lock calls is just a door out of alignment, not a broken lock. We adjust it before we ever talk about new parts.
The mortise lock is the in-frame body that grabs the keeper. We replace it to bring back a smooth key turn and reliable deadbolt engagement. It fits Andersen, Pella, PGT, CGI, and ESW sliders.
The keeper is the strike on the fixed panel that catches the lock hook. When it drifts out of line the lock will not fully engage, which people often mistake for a broken lock. We realign it.
The cam hook is the swinging hook inside the lock body. We replace it when the hook shaft wears down or the return spring gives out and the lock stops catching.
We service base-mounted foot locks, pin locks, and cam locks. These secondary locks are common on older Andersen and Pella units and add a second point of security.

Here are straight answers to the questions we hear most about sliding door lock repair.
Difficulty engaging a sliding door lock is usually caused by misalignment between the lock latch and the keeper on the door frame. This can result from the door settling on worn rollers, track debris shifting the door's position, or the keeper itself becoming loose. Our technicians realign these components and address the underlying cause for a lasting fix.
Many sliding door lock issues can be resolved through repair, including realignment, internal component replacement, and mechanism adjustment. We always attempt repair first as the most cost-effective solution. If the lock body is cracked, severely corroded, or the internal mechanism is beyond repair, we will recommend replacement and explain why.
Lock repair costs depend on the type of lock, the nature of the problem, and whether replacement parts are needed. Simple realignment is at the lower end of the scale, while internal mechanism repair or component replacement costs more. We always provide a clear quote before starting work so there are no surprises.
Yes, a lock that does not fully engage or can be forced open with minimal effort is a significant security vulnerability. Sliding doors are common entry points for break-ins, and a compromised lock makes unauthorized access much easier. We recommend having lock issues addressed promptly to maintain your property's security.
Most lock repairs are completed within 30 minutes to one hour on-site. More involved repairs that require disassembling the lock mechanism or addressing frame alignment may take up to two hours. We carry common lock parts on our service vehicle, so most repairs are completed in a single visit.
That is almost always the keeper, the metal plate on the fixed panel that the latch hooks into. When the door settles or the keeper works loose, the latch passes by the slot instead of into it. Resetting the keeper position usually fixes it, and it is one of the quicker repairs we do.
Yes. Patio door and sliding glass door describe the same opening, and the lock work is the same. Older aluminum frames often use cartridges that are no longer made, so on those we fit a current mortise lock and adapt the mounting instead of replacing the door.
