Locksmith in St. Louis, MO

A Mobile Locksmith for St. Louis City

From a brick two-family in Tower Grove South to a loft near the Gateway Arch, St. Louis City has every kind of door and lock there is. Prime Locksmith Services is a family-owned mobile locksmith that works across the city’s neighborhoods, from Carondelet and St. Louis Hills on the south side to the streets around Forest Park.

We open locked homes, apartments and cars, rekey and replace locks, cut keys and program fobs, all from our van at your door. You get the price on the phone before we come out, and you deal with a local technician, not a national call center.

Emergency Locksmith Service in St. Louis

When a lock fails at the wrong moment, here is how we help in the city.

Urgent lockouts

Locked out of a home on The Hill, or a car parked off I-44 with the keys inside? Our St. Louis emergency locksmith service gets you back in without damage and secures the door before we leave.

After a break-in

Report it first to the St. Louis Metropolitan Police Department at 314-231-1212 (911 if the intruder may still be there). Then call us to repair the door, replace the damaged lock and rekey the rest.

A city of renters

About 55% of homes in St. Louis are renter occupied, according to the U.S. Census. We rekey between tenants for landlords and change locks for renters with the landlord’s approval.

Locks, Leases and Move-In Day in St. Louis

St. Louis requires a Certificate of Inspection before anyone moves into a rental unit or a home that has just been sold, and rental units are reinspected every three years or when occupancy changes. That inspection cycle is a natural moment to rekey, because nobody can tell you how many keys the last occupant handed out.
