Clayton packs a lot into a small footprint: the St. Louis County courts and government offices, law and finance firms, pre-war apartment blocks in DeMun, and quiet residential streets like Brentmoor Park and Carrswold. Prime Locksmith Services works all of it, from a jammed office suite door near Forsyth to a lockout on a student apartment off Wydown Boulevard.
We are a mobile, family-owned locksmith, so we come to your building with the tools, keys and hardware to fix the problem on the spot, and we quote the price before we drive over.
