A customer who asks, "How much to change my locks?" may need a residential rekey, several replacement deadbolts, or help securing a damaged door. Those jobs involve different parts and labor. A short, ordered set of questions gives an owner-operator or small locksmith shop enough detail to offer a useful estimate and prepare the technician.
Start with rekeying versus replacement
Customers often use "change the locks" to mean any work that makes old keys unusable. Ask about the desired result before assuming they want new hardware.
Rekeying changes the working key while keeping compatible lock hardware in place. It may suit locks that work properly when the customer wants to invalidate old keys after a move, tenant turnover, or lost key.
Replacement removes some or all of the lock hardware. It may be needed when a lock is damaged, worn, incompatible with the requested keying, or unsuitable for the door. Customers may also want a different finish, function, or lock type.
A useful opening question is: "Are the current locks working normally, and are you mainly trying to make the old keys stop working?" The answer guides intake. The technician confirms the scope onsite.
Count doors and cylinders
"Three doors" does not describe a complete job. One door might have a keyed knob and deadbolt, while another has a single cylinder. Ask how many keyed locks or cylinders are on each opening and what type of hardware is present, such as a knob, lever, deadbolt, handleset, mortise lock, rim cylinder, keypad, or panic hardware.
Record any double-cylinder locks that use a key on both sides. Also identify glass storefront doors, fire-rated doors, gates, and commercial openings. Loose, jammed, damaged, or missing hardware can change the work required.
Photos help when callers do not know the terminology. Request clear images of both sides of the door and the edge where the latch or bolt sits. The caller should never disassemble a lock for intake.
Ask about brand and keyed-alike goals
A brand name may appear on the deadbolt face, latch plate, key head, or interior trim. Ask whether all locks look like the same brand and whether one key already operates several doors. Mixed brands or keyway families may require different cylinders, special parts, or replacement hardware.
Clarify which openings should share a key. A homeowner may want one key for every exterior door but keep a workshop separate. A property manager may need unit doors separated while common-area locks follow another keying plan. Existing hardware does not always support the requested arrangement, so compatibility needs onsite confirmation.
Identify the caller's relationship to the property
Ask whether the caller is the homeowner, tenant, landlord, property manager, business owner, or another representative. Then confirm who will meet the technician and who can approve the work.
A tenant may need landlord approval or must follow building key requirements. A property manager may need to provide the unit, onsite contact, billing contact, and information about master-key or restricted-key systems. For every caller, explain the shop's identification and authorization policy before dispatch.
AI-assisted intake can collect and organize these details. It should not decide whether a person has legal authority or claim that authority has been verified. The locksmith follows company policy and applicable law before starting work.
Identify safety urgency without prying
A call may involve a lost key, suspected unauthorized access, break-in damage, a domestic safety concern, or a door that will not secure. Dispatch needs enough information to prioritize the request and keep the visit safe. The caller does not need to share personal history.
Ask whether anyone is in immediate danger, whether the property can currently be secured, whether the door or frame is damaged, and whether emergency services are already involved. If someone reports immediate danger, direct them to local emergency services according to shop policy. Intake software may flag the caller's stated urgency for staff review, but it should not decide whether an emergency exists.
Avoid questions about who the caller fears or why a relationship ended. Record only what affects safe access, scheduling, and the requested locksmith work.
Confirm access and site conditions
Find out who will be onsite and how the technician will enter. Ask whether the caller is locked out, whether another entrance is usable, and whether gates, building staff, parking rules, pets, alarms, or tenant schedules could affect access.
For vacant rentals and managed properties, collect lockbox or entry instructions through the shop's approved secure process. Sensitive access codes do not belong in open notes or text chains. A phone conversation, photo, lease, or ID should never be presented as automatic proof of legal authority.
Explain why blind quotes are unreliable
A blind quote treats every lock-change call as the same job. The scope can shift when the technician finds an extra cylinder, incompatible brands, a damaged latch, a misaligned door, unusual commercial hardware, or a keyed-alike request that the existing locks cannot support.
A useful estimate states its assumptions. It might cover a stated number of serviceable residential cylinders during normal hours, with replacement parts quoted after inspection. Explain service-call charges, keys, hardware, after-hours work, and travel according to the shop's actual policy.
Use a range or conditional estimate when the hardware has not been inspected. Repeat the recorded scope before booking and note which details still need onsite confirmation.
Final qualifying-questions checklist
