Locksmith Letting Agent Work: How to Win Repeat Instructions

A letting agent sends an address and a tenant’s number, but nobody says who authorised entry or who can approve a new lock. That is how locksmith letting agent work turns into waiting, unpaid extras and disputed invoices.

Treat the agent as an account. Set the rules before dispatch. Keep every instruction, approval, key movement and completion record against the property.

Decide whether the account fits your operation

Letting agents need more than a locksmith who can open a door. They need somebody who answers the booking, checks authority, attends when agreed, controls keys and sends paperwork their office can understand.

Start by writing down the work you will accept. Your service list might include:

• Emergency entry after authority checks
• Tenant lockouts
• Failed lock diagnosis and repair
• Lock replacement where repair is not suitable
• Planned lock changes between occupancies
• Key cutting and controlled key handover
• Door and surrounding hardware checks
• Planned security work agreed with the property manager

Do not promise every service at every hour. State your coverage area, booking channel and availability in plain language. If emergency attendance depends on who is available, say that. Give a live update after the job is accepted rather than making an arrival promise you cannot control.

Check whether your office process can keep up. Somebody must record the instruction, contact the occupier, monitor approvals and send the completion record. Fast entry followed by missing paperwork still creates work for the agent.

If attending alone forms part of your operation, set a procedure for check-ins, site risks and failed contact. Check current lone-working guidance with the Health and Safety Executive (opens in a new tab) before writing that procedure.

Set the account rules before accepting the first instruction

Ask the letting agent for a named account contact. Then ask who may book work, who may approve extra work and where invoices must go. Those people may not be the same.

Record the following account rules:

• Properties or branches covered
• Services you will accept
• Normal booking method
• Emergency contact method
• People allowed to instruct work
• People allowed to approve extra work
• Billing name and address
• Purchase order or job reference requirements
• Key collection and return process
• Completion evidence required

Set an approval route, not just an approval limit. You need to know who to call when the lock described in the booking cannot be repaired. Record a backup contact for cases where the main property manager is unavailable.

Separate emergency entry from planned work. An emergency booking needs immediate authority and occupier checks. A planned lock change allows time to inspect photographs, identify hardware and agree key quantities before attendance.

Use the same rules for landlords, letting agents and other commercial locksmith clients. The names change. The control points do not.

Confirm authority and access before dispatch

Property access authorisation comes before the van moves. Do not try to reconstruct it after opening the door.

The instruction should identify:

• The full property address and postcode
• The person requesting the work
• The company or landlord responsible for payment
• The occupier or site contact
• The reported fault
• The requested outcome
• The person authorised to approve the work
• The intended access method

Ask whether the property is occupied. Ask who may be inside and whether they expect the visit. Confirm whether the tradesperson will meet a tenant, collect management keys or attend with an agent.

A tenant reporting a failed lock may be allowed to arrange access but not approve replacement hardware. A property manager may approve the work but have no direct knowledge of who is inside. Keep those roles separate in the job record.

Apply lockout customer verification and emergency entry checks at every access job. Match the caller, address, instruction and person on site before starting. The exact evidence available will vary, so use a recorded decision process rather than relying on familiarity or urgency.

For a fuller access-checking process, use the locksmith proof-of-address and right-to-enter guide.

Stop when the details do not line up. Call the authorised account contact. Record what did not match and wait for a clear instruction. A busy letting office is not a reason to weaken the entry check.

Triage the fault before choosing the appointment

Ask what the door is doing, not just what the caller thinks the lock needs. “Jammed lock” is a report. It is not a scope.

Ask for clear photographs of the door, lock, handles, frame and visible damage where practical. Ask whether the door is open, closed or insecure. Ask whether a key turns, sticks, spins or has broken. Record any attempted forced entry or damage around the hardware.

Then choose the purpose of the visit:

• Entry only, followed by an inspection
• Diagnosis before a quote
• Repair within an agreed scope
• Replacement of identified hardware
• Temporary make-safe work before a planned return

Do not turn a repair booking into an automatic replacement. Inspect the lock, door, frame and surrounding hardware first. A replacement may need different materials, more labour and fresh approval.

Tell the agent what happens next. Confirm that the booking has been accepted, who will contact the occupier and when the next attendance update will be sent. A realistic update is more useful than an unsupported arrival time.

Scope and price locksmith letting agent work

Build the price from the job in front of you. Include labour, materials, equipment costs, overhead and markup. Do not invent a standard lockout rate and hope every door fits it.

Labour includes attendance, inspection, entry, repair, fitting, testing and job records. Materials include the lock, cylinder, keys, fixings and other hardware required by the agreed scope. Equipment costs belong in the calculation where the job consumes or uses them. Overhead covers the business costs that cannot be assigned neatly to a single door.

Markup is what you add to cost to reach the selling price. Margin is the profit left as a share of that selling price. Use your own costs and target, or work through the practical job-pricing method.

A sound quote for locksmith letting agent work states:

• The property and instruction reference
• The fault reported
• The work included
• The hardware included
• Key quantities or key handling included
• Attendance assumptions
• Access assumptions
• Exclusions
• The approval route for extra work
• The payment and invoice details agreed for the account

Keep repair and replacement as separate scopes. If the initial instruction covers diagnosis and repair, say whether replacement is excluded until the lock has been inspected. This prevents the person on site from being asked to approve work they do not control.

Stop and write a variation when the scope changes

The lock described as jammed may be damaged beyond the quoted repair scope. Stop. Photograph the condition. Describe the replacement needed. Send the price and get approval from the named contact before fitting it.

Record the variation against the original instruction. Include who approved it, what changed and how the price changed. A phone conversation can move the job along, but follow it with a written record before continuing.

Worked example: scope, variation and invoice

Oak Street is the house electrical example from another trade. It shows how the same control works when the site condition differs from the quote. All figures are sample currency units, not a rate card.

R. Chen’s job at 14 Oak Street covered a bathroom exhaust fan, ducted through the roof, and four LED downlights. Quote Q-1847 was 1,105. The ceiling was lined and the quote excluded chasing.

Extra cable and chasing were approved on site as a 160 variation. Invoice INV-1847 was therefore 1,265.

The original quoted scope had a job cost of 850. Against the original quote, profit was 1,105 − 850 = 255. Margin was 255 ÷ 1,105, or about 23%. Markup was 255 ÷ 850, or 30%.

Do not calculate profit by subtracting 850 from the 1,265 invoice. The costs belonging to the 160 variation are not given. Combining the revised invoice with the original job cost would produce a false result.

Keep useful locksmith key records

A key without a property record is a loose security item. Record custody from collection to return.

Your locksmith key records should connect each key or set with:

• The property
• The job reference
• The collection or issue event
• The person handing it over
• The person receiving it
• The door or purpose it relates to
• The return destination
• The return status

Describe keys clearly enough to control them without spreading unnecessary security information. Avoid putting detailed access notes into messages that do not need them. Keep key records with the restricted property job rather than in a general diary entry.

Before changing a lock, ask who should receive the new keys. Confirm the quantity in the approved scope. At handover, record who received them and what happened to any old or management keys.

If a tradesperson receives a key set but the job does not state how many keys were supplied, which door they open or where they must be returned, stop and update the record before leaving the collection point.

Hand over a job the agent can close

The door working is not the end of the office job. The letting agent needs a short record that explains what happened without another phone call.

Write the handover in plain language:

• Fault found
• Entry method or work completed
• Lock or hardware repaired or fitted
• Final door condition
• Keys issued, received or returned
• Variation approval reference
• Any work still required

Attach photographs that prove the useful facts. Show the relevant condition before work where possible, the fitted hardware and the secure final condition. Do not collect unrelated photographs from an occupied home.

Tell the site contact what changed. Demonstrate the lock where needed. Confirm who has the keys and where management keys are going next.

Send the completion record to the property manager. The office should be able to match the address, instruction, approval and finished work without asking the tradesperson to remember the visit later.

Match the invoice to the instruction

Use the same property address and job reference shown on the booking. Name the approved scope. Show an approved variation separately so the accounts team can trace it.

Write the work description for somebody who was not on site. “Works completed” says nothing. State the fault found, the repair or replacement completed and the final condition of the door.

Send the invoice with the completion record, photographs required by the account and approval reference. Missing evidence delays the agent’s internal check even when the work itself is sound.

Before sending, check the billing party. The tenant, landlord and letting agent may all appear on the job, but only the agreed party belongs on the invoice.

Review cost tracking before taking more of the same work

Repeat work is only useful when you know which jobs make money. Review each finished instruction using the selling price for the agreed scope and the actual costs belonging to that scope.

Compare estimated and actual:

• Travel and site labour
• Office time spent arranging access
• Materials and keys
• Equipment costs
• Return visits caused by missing information
• Time spent chasing approval

Keep variation costs separate when you can. That lets you test the original scope and the changed scope without mixing them.

Check job profitability by job type and by agency account. A lock repair may have been priced correctly but weakened by repeated failed access. Another account may send complete instructions that keep office time down. The invoice total alone will not show that difference.

Use the finished-job cost tracking process to compare the quote with actual labour and materials. Then change the next scope, booking questions or approval route where costs went missing.

Common questions

Is locksmithing a good side hustle for letting-agent work?

It can fit only if your promised availability matches the hours you can cover. Letting agents also expect access checks, status updates, key control, completion records and invoices. If limited hours leave those tasks unfinished, do not offer an emergency service you cannot support.

Start with planned jobs or a tightly defined coverage window. Write the boundary down and make it part of the account rules.

How do you turn one completed instruction into repeat work?

Make the finished job easy for the property manager to close. Send the completion note, photographs, key status, approval reference and invoice together. Then ask whether another property has a planned lock, key or access issue that needs inspection.

Keep the follow-up about the property portfolio, not a vague request for more work. The same operational principle applies across trades; the call-out follow-up process for winning repeat work gives a practical structure.

What if nobody can approve extra work while you are on site?

Do only the work already authorised and leave the property in the agreed condition. If the door needs temporary security work, describe the immediate problem and ask the named contact for approval before changing the scope.

Record the delay, photographs and contact attempts. Do not ask the tenant to approve costs unless the account record says they have that authority.

Send the agent an account onboarding sheet

Use a short document. The agent should be able to complete it without a meeting.

Send this sheet before accepting regular locksmith letting agent work. Use the answers to build the property file and reject incomplete instructions before they reach the van.

Yes Foreman can keep the instruction, quote, variation, key notes, completion evidence, costs and invoice attached to the same job. See the job setup for locksmith businesses if you need a place to hold that record.

Create the blank onboarding sheet now. Send it to the letting agent who last asked you for a lock job, and ask them to name the people allowed to instruct and approve the next visit.
