Lock Repair in Cupertino, CA.

If you need lock repair in Cupertino, this is how One & Only Locksmith handles it.

Lock repair finds the actual reason a lock sticks, spins or will not latch and fixes that part instead of replacing the whole lock. The cause is often a cylinder gummed up with the wrong lubricant, a sheared tailpiece, a weak spring, a strike that no longer lines up, or a door that has dropped on its hinges. We replace what has failed and leave the rest of the hardware in place.

The technician comes to your address in Cupertino, in Silicon Valley. The dispatch line at (888) 492-0666 is answered around the clock, and the dispatcher confirms the details and an ETA before anyone is sent.

• Inspection of the cylinder, latch, bolt, strike, hinges and door alignment to pin down the failure
• Cleaning and dry lubrication of a cylinder that has gummed up from oil-based sprays or dust
• Replacement of broken springs, tailpieces, thumbturns, retainer clips and spindles
• Strike plate adjustment or relocation so the bolt throws fully without lifting the door
• Hinge screw replacement and shimming for doors that have sagged into the strike
• Re-pinning a cylinder whose pins have worn to the point the key hangs up
• Function test with the door closed and a straight answer on whether the lock is near the end of its life

• What the lock does: key will not go in, goes in but will not turn, turns but the bolt does not move, bolt stops short, knob spins free, latch will not catch
• Whether it happens with every key or only one copy
• Whether it got worse over months or failed suddenly
• Whether anyone has sprayed oil or penetrating lubricant into the keyway
• The brand on the lock face or the key bow if you can read it
• Proof of residency, and the landlord's contact if you rent, since the owner usually approves parts replacement

Typically 20-45 minutes for a single lock. Seized cylinders that must be fully disassembled, strike relocation that needs the jamb chiseled, hinge repair, and locks whose parts have been discontinued take longer.

• Builder-grade locks often cost more to rebuild than to replace; when that is the case we quote the replacement and let you choose
• Cylinders with an elongated keyway or pins worn out of tolerance are replaced rather than repaired, because fresh pins will not fix a plug that is out of spec
• Parts for discontinued or imported locks may not be available, and the repair then becomes a replacement
• A lock on a warped door or a shifted frame keeps failing until the door is fixed; carpentry is outside lock repair
• Smart locks with a failed motor or circuit board are handled under the manufacturer's warranty or replaced; they are not rebuilt on site
• Restricted and high-security cylinders are serviced only with the authorization the manufacturer requires, and some must go back to the dealer

The price is driven by diagnosis time, the parts replaced, whether the cylinder has to be disassembled or re-pinned, any strike or hinge work, and the time of day. If a repair is not worth it, we quote the replacement alongside so the choice is yours.

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