Onyx Lock N Key

A good first visit is half diagnosis and half estimate — if a provider commits to numbers before walking the job, treat that as a warning sign. Onyx Lock N Key shows up in Portland, ME as a swift lock candidate worth scoping before booking. The notes below separate public-source documentation from what still needs to come from the dispatch line. No structured service signals are present in the public-source pass for this listing. That makes the dispatch conversation the primary signal — ask which services they actually perform versus those that get subcontracted. No structured homeowner use-case mapping is on file. Ask the dispatch what their typical recent jobs are — small repairs, full replacements, or commercial maintenance contracts. A defensible quote should break out major job phases — diagnosis, parts, labor, follow-up — as separate line items. If they bundle everything into a single round-number fee, ask what is and is not included.
