Michigan locksmith marketing that gives callers a filed name, an honest price and a real arrival time

A caller standing outside a locked house in Warren cannot look you up on a state license board, because Michigan has none for locksmiths. What they can check is your name, your address and whether the two match everywhere they look. Make that match your first job.

The trade group ALOA lists the states that license locksmiths, and Michigan is not among them. Neither are Ohio, Indiana or Wisconsin. So a shop near Toledo or the Indiana line has no neighboring license to borrow as proof, and no fake listing has one either. The locksmith page covers why fake call centers thrive in that gap.

Michigan does ask one thing of a shop with a brand. An owner who trades under any name other than their own files a certificate with the clerk of every county where the business works or keeps an office, under the assumed name law. That statute sets the fee at $6 per filing, and lets a county of over two million people set its own. Corporations and limited partnerships sit outside that county rule.

For a mobile shop, "every county" matters. A van that runs Wayne, Oakland and Macomb works in three counties. Each clerk's certificate is a public record a caller, a reporter or Google's reviewer can find.

• One name, everywhere. The name on the certificate goes on the Google profile, the site footer, the van and the invoice.
• The same name in the ads. Google's locksmith ad policy wants your legal name or a registered fictitious name, and nothing else.
• Verification takes a while. Google's help page says its locksmith review typically takes 6 to 8 weeks, so the paperwork starts before the ad budget does.

Property managers in Lansing, Kalamazoo and Detroit change keys every time a unit turns over. That makes them steady, repeat customers. But some calls from owners ask for something the law does not allow, and your phone script should catch them.

Michigan's tenant lockout law counts changing or adding locks without immediately giving keys to the tenant as unlawful interference. Under that law, a tenant can recover actual damages or $200, whichever is more, for each occurrence. Removing locks or doors is on the same list.

The law names when an owner may act. A court order is one. A good-faith belief that the tenant has abandoned the unit, with rent unpaid, is another. Short repairs and inspections allowed by law are a third.

So the intake script asks three plain questions before a van rolls:

• Is the unit empty, between tenants?
• If not, does the tenant get a key today?
• If not, is there a court order or a court officer on site?

A yes to any one of them is a normal job. Three noes means the owner is asking you to help with an eviction the court has not ordered. Write that answer down and pass on the job.

The upside is the turnover work itself. A rekey package priced per door, with a key log the manager can show a new tenant, sells to every company running more than a few units.

Michigan does not have one locksmith season. The cold runs longer inland, campus towns empty and refill on a schedule, and Detroit's suburbs are separate markets. Budget each one on its own.

Cold first. NOAA's 1991 to 2020 normals give Lansing 142.5 nights a year at or below freezing. Flint logs 140.8 and Grand Rapids 133.1. Detroit Metro Airport has 119.5. In our experience, frozen car locks and dead fobs follow those nights, so mid-Michigan ads get the longest winter run.

Students next. The Census Bureau's city estimates put East Lansing at 48,030 in 2020, 34,857 in 2021 and 49,355 by 2025. A town that can lose a quarter of its people when campus empties has a rekey rush every time leases change hands. Those dates belong on the calendar for any shop near East Lansing or Ann Arbor.

Detroit last. The city's estimate in the same file has grown three years running, to 649,095 in 2025. Yet the city is one slice of the metro. The Michigan page explains why Wayne, Oakland and Macomb rank apart, so each gets its own ad group and its own landing page.

• Detroit tri-county: car keys and lockouts all year, with commercial rekeys in Troy, Southfield and Livonia office parks.
• Grand Rapids and Kentwood: a long winter on the west side, with its own ad group and its own reviews.
• Lansing and East Lansing: the longest freeze season, plus lease turnover around the campus calendar.
• Ann Arbor: student rentals and university-area landlords, priced per door.
• Flint: a cold-weather lockout market with a small footprint, worth a modest budget.
