Key Takeaways
- Scenario 93 is locksmith / key-blank impression MMS — not storm-limb tags, radon gauges, irrigation valves, elevator plaques, or garage-door springs.
- A cropped blank silhouette and pin count are the payload. Do not MMS door hardware, house numbers, or neighbor yards.
- Read MMS and “cut complete” SMS must not share a radio with portal OTP or a “book a rekey” blast.
- Priced by devices and SMS send volume. You use your own phone and operator SMS credit. Free is 1 / 300 / 300. Developer is 25,000 SMS per year.
- Operator MMS is usually dearer than SMS. Budget after-hours calls separately.
- REST attachment fields live in Developer Center — not a CodeCanyon locksmith add-on. MCP, if you use it, is only a REST wrapper.
Summary
Scenario 93 is field-service MMS for locksmith key blanks. Dispatch owns the job id. The van Android still has to send “blank BLANK-4, 6-pin” without attaching the whole door. Priced by devices and SMS send volume. You use your own phone and operator SMS credit.
A wide lock-face selfie is not proof of cut. It is a security leak — and a second MMS when dispatch retries the same job.
