Door Knob & Handle Repair across greater Los Angeles, Ventura County & the Bay Area.

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

Knobs and levers fail at a few predictable points: the spindle or tailpiece strips so the knob spins without pulling the latch, the spring cassette weakens so a lever droops, a set screw loosens so the handle wobbles, or the latch itself jams. Many are fixed with internal parts; the rest are replaced with hardware in a matching finish, and keyed exterior levers are keyed to your existing key when the keyway allows.

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 the failure: spindle, latch, spring cassette, rose, set screw or door alignment
• Tightening or replacing through-bolts, set screws and roses on loose knobs and levers
• Replacement of broken spindles, tailpieces, latch assemblies and spring cartridges
• Freeing stuck privacy locks on bathroom and bedroom doors and replacing push-button or turn-button mechanisms
• Full knob or lever replacement in a matching finish when the body is worn out, keyed to your existing key where compatible
• Knob-to-lever swaps for easier use by anyone with limited grip strength
• Strike adjustment so the latch catches without slamming the door

• Knob spins without retracting the latch
• Lever droops and won't lock or unlock
• Latch refuses to retract even with the right key
• Privacy knob on bathroom door is stuck in the locked position
• Want to upgrade from knobs to ADA-friendly levers

• What the knob or lever does: spins free, droops, will not turn, will not latch, or is stuck locked
• Which door it is on: interior passage, interior privacy, or exterior keyed
• The brand if it is stamped on the latch face (Kwikset, Schlage, Weiser, Defiant, Baldwin)
• The finish you want matched
• Ownership proof, or the landlord's contact if you rent, since the owner usually approves hardware replacement

Typically 20-40 minutes for a repair or a straightforward replacement. Older mortise knob sets with cast bodies, discontinued designer hardware, and doors where the bore has worn oversized take longer.

• Builder-grade knobs often cost less to replace than to repair; we say which it is before doing either
• Discontinued designer hardware from older Baldwin, Emtek and similar lines may need parts ordered or a full set replaced
• Mortise knob sets on older homes use a lock box in the door edge; parts are rebuilt or the box is replaced with a compatible mortise lock, not a modern tubular knob, unless you want the door reworked
• A keyed lever with a worn or stripped cylinder gets a new cylinder; a cylinder that is out of tolerance cannot be rekeyed back to health
• Lever handles must clear the door stop and nearby trim, and some doors need a different rose size to cover old marks
• A knob that is loose because the bore has worn oversized needs a wrap-around plate or door repair, not just tighter screws
• In a rental, hardware replacement is usually the owner's call

The quote depends on whether the fix is parts or a full replacement, the hardware grade and finish, keyed versus passage or privacy function, keying to your existing keys, and the number of doors.

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.

• Kwikset Tylo, Juno and Halifax; Schlage F-series (Georgian, Plymouth, Accent, Latitude); Weiser and Defiant
• Baldwin Estate and Reserve, Emtek and Yale residential knobs and levers
• Replacement latches in 2-3/8 and 2-3/4 inch backsets, drive-in and faceplate styles
• Privacy turn-button and push-button assemblies, spring cassettes and spindles
• Mortise knob sets and skeleton-key locks on older homes
• Lever sets with a return for easier operation

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.
