Google Maps is spammed by fake locksmith or other trades that make it look like they're local but all route to the same boiler room (probably right next to the tech support or IRS scammers) from where they dispatch a crooked & most likely unlicensed tradesman that will do a poor job and overcharge you (destroying the lock so they can sell you an overpriced replacement instead of picking it, etc). For licensed trades the solution is to go to your official trade licensing body (for the UK it's the NICEIC for electricians and the Gas Safe Register for gas/HVAC technicians), for unlicensed ones it's more difficult. There are "review" sites that claim to provide good results but their business incentives & vulnerability to spam/fake reviews are unknown.
