Locksmith invoices and authorization forms: protect every job
Short answer: A locksmith should never open a lock, cut a key or rekey a property without a written record of who asked for the work and why they are entitled to ask. The core set is an estimate, an authorization form that records identity and proof of ownership or right of access, a work record, and an invoice that matches the estimate.
Why authorization is the form that protects you
Locksmith work is sensitive: the same service that helps a locked-out owner could help someone who has no right to enter. An authorization form records who requested the work, how identity was checked, and what proof of ownership or right of access was shown. It shows that you acted in good faith.
Keep the form short enough to complete at the door. Record the name, the property or vehicle, the type of proof, the work authorised and a signature, and store a copy with the job. Check your state and local licensing rules for any extra requirements.
Quote first, especially for emergencies
Emergency calls are where price disputes start. Give the customer a clear estimate before work begins: a service call fee, the labor for the job, parts, and any after-hours surcharge. A signed or acknowledged estimate prevents the argument that the final price was a surprise.
If the job changes on site, such as a high-security lock that needs a different part, update the estimate and get approval again. A short written change is better than a longer verbal debate later.
Vehicle and key work records
Automotive jobs carry extra detail: make, model and year, the VIN where required, the type of key or fob and whether it is programmed on site. A vehicle record protects you if the key later fails or the owner claims damage.
For master key and access control work, keep a key log that records who holds which keys and when they were issued or returned. It is the record a property manager will ask for when a key goes missing.
The invoice that gets paid
Use an invoice that mirrors the estimate line by line and shows the date, the address of the work, the amount, accepted payment methods and the warranty period on parts and labor. Send it at completion while the customer is still satisfied.
Sequential invoice numbers and a consistent header make your records easy to hand to an accountant, which matters at tax time.
Frequently asked questions
Do I need an authorization form for every job?
For lockouts, rekeying and key duplication, a written record of who requested the work and what proof they showed is good practice. Confirm what your state requires.
What belongs on a locksmith estimate?
Service call fee, labor, parts, any after-hours surcharge, the work description and an expiry. Get acknowledgement before starting.
Can I add my license number to the forms?
Yes. The headers are editable for your business name, logo and license details.
