Patio & Sliding Door Lock Repair across greater Los Angeles, Ventura County & the Bay Area.

This page explains patio & sliding door lock repair: what the job includes, what to have ready, honest limits and what sets the price.

Sliding glass doors lock with a hook-style mortise latch set into the door edge that catches a keeper on the jamb, and hinged patio and French doors use a mortise lockset or a multipoint lock that runs the height of the door. Over time rollers wear, the panel drops, the hook misses the keeper, and the latch housing or handle breaks. Repair means identifying which part has actually failed and replacing it with a matching or universal component.

We dispatch across greater Los Angeles, Ventura County, Silicon Valley and the Bay Area; see the city pages for local detail. The dispatch line at (888) 492-0666 is answered around the clock.

• Diagnosis of whether the problem is the latch, the keeper, the rollers or the track
• Replacement of the mortise latch cartridge with the correct hook style, handle spacing and backset
• Keeper adjustment or replacement so the hook engages fully with the door closed
• Roller adjustment or replacement so the panel sits high enough to latch and slides freely
• Replacement of handle sets, including keyed exterior pulls where the door takes one
• Multipoint lock gearbox and handle repair or replacement on French and hinged patio doors
• Secondary security hardware: foot bolts, loop locks, security bars and anti-lift blocks

• Patio door won't latch when closed
• Sliding glass door has come off its track
• Mortise lock body inside the door has failed
• Charley bar or security bar bent or missing
• French doors won't align after settling

• The door brand if there is a sticker on the frame or glass edge (Milgard, Andersen, Pella, Jeld-Wen, Marvin)
• Photos of the latch face on the door edge and of the handle, inside and out
• Whether the door is hard to slide (rollers or track) or slides fine but will not latch (latch or keeper)
• The distance between the handle screw holes if you can measure it, since that identifies the handle set
• Ownership proof or written landlord authorization

Typically 30-60 minutes for a latch cartridge, keeper or handle replacement. Roller replacement that requires lifting the panel out of the track, multipoint locks on French doors, and discontinued hardware that needs a universal substitute or an order take longer.

• Many sliding door latches are proprietary; when the manufacturer no longer makes the part, a universal replacement may change the handle look or need new holes
• Rollers and the track are frequently the real problem; a latch cannot be made to work on a panel that has dropped, so roller service may have to come first
• A badly worn or corroded aluminum track needs a track cap or a new track, which is door work beyond the lock
• Multipoint locks on French doors (Hoppe, G-U, Fuhr) use model-specific gearboxes that are identified from photos and often ordered
• A sliding door cannot take a conventional deadbolt; its security comes from secondary locks and anti-lift pins, and the glass itself remains the limit
• Keyed exterior pulls exist for only some door models; others cannot be locked from outside
• Rentals need owner authorization, and HOAs may have rules on exterior hardware appearance

The price follows the part needed (latch cartridge, keeper, rollers, handle set, multipoint gearbox), whether the panel has to come out of the track, whether a universal replacement needs new prep, any secondary locks added, and the time of day.

The dispatcher gives you a range on the phone, and the technician confirms a written quote before any work starts.

Payment is by Cash, Credit Card, Debit Card, Apple Pay and Google Pay, and you receive an itemized receipt listing what was done.

• Mortise hook latch cartridges with 45-degree and 90-degree keyways for Milgard, Andersen, Pella, Jeld-Wen, International and Columbia doors
• Keyed and non-keyed sliding door handle sets (Prime-Line, Strybuc, manufacturer originals)
• Tandem and single steel and nylon rollers for aluminum and vinyl panels
• Multipoint locks and gearboxes for French and hinged patio doors (Hoppe, G-U, Fuhr, Truth)
• Foot bolts, loop locks, security bars and keyed patio door pins

Repair makes sense when the lock body is sound and the problem is alignment, a worn spring, a loose spindle or a sticking cylinder. Replace when the lock is worn through, parts are discontinued, the door was forced, or you want a higher grade. On sliding and patio doors the hook or latch is often replaceable without changing the handle set; on garage and gate hardware the latch and the lock are usually separate parts.
