Locksmith invoices get disputed when the service call, labour, and hardware are mashed into one number. Customers understand “$95 to get me in” plus “$35 per cylinder re-keyed” plus the deadbolt they can see. They do not understand a $340 lump sum after a 20-minute lockout.
This template starts with a service call, three re-key cylinders, and a Grade 1 deadbolt so you can edit instead of starting from a blank invoice. Emergency after-hours work is called out in the terms at 1.5×.
Include the service address, whether it was a lockout, re-key, install, or automotive job, and how many cylinders or keys were involved. If you opened a vehicle, note the make, model, and last four of the VIN when you have it — insurance and fleet accounts ask.
Hardware should be its own line (lockset, deadbolt, keypad, closer). Do not bury a $145 lock inside “labour.” Sales tax usually applies to parts; labour rules vary by state.
Pre-filled numbers you can overwrite on site or back at the van.
| Line item | Qty | Rate | Amount |
|---|---|---|---|
| Service call & lockout service | 1 | $95 | $95 |
| Re-key cylinder | 3 | $35 | $105 |
| New deadbolt — Grade 1 commercial | 1 | $145 | $145 |
| Sales tax (7%) | — | — | on taxable items |
Residential lockouts are due before you leave. Re-key and install jobs for property managers are often Net 15. Automotive and safe work can be higher ticket — take a card on file or collect before the job if the customer is not a repeat account.
State the after-hours multiplier in writing. “24/7 emergency at 1.5×” on the invoice prevents the 11pm argument at the door.
Yes. A visible service-call line is the industry norm and is easier to defend than a padded labour rate.
Per key or per cylinder. Customers compare those unit prices. A lot total hides the math and invites haggling.
Charge the service call / diagnostic and note “repair declined.” Do not leave that visit unbilled.
Yes — many cities require it. Add them under your business details so they print on every invoice.
Collect before you leave. Lockout customers you will never see again are the highest non-pay risk in the trade.
