Lock and key service in Frontenac

Frontenac is one of the smallest and most affluent cities in St. Louis County, sitting between Ladue and Creve Coeur near Plaza Frontenac. Homes here tend to sit on acre-plus wooded lots, often French Provincial or Colonial in style, with gated entries and multiple outbuildings — a detached garage, a pool house, sometimes a guest house — in addition to the main residence.

That changes what a typical call looks like. Instead of one front door lock, a Frontenac property often has a wrought-iron entry gate, several structures that ideally share one key, and higher-end designer hardware that a generic locksmith isn’t stocked to service. We carry the cylinders and smart lock brands that fit that kind of hardware, and can master-key an entire property — house, garage, and pool house — to one key.

What we handle here

  • Estate gate entry systems — lock and keypad service for gated driveway entries
  • Multi-structure master keying — house, detached garage, and pool house on one key
  • Lock rekeying after a purchase, a move, or a lost key
  • High-security and designer hardware fitted to custom entry doors
  • Smart and keypad locks for main and secondary entrances
  • Deadbolt installation and upgrades
  • Car lockouts — vehicle opened without damage (we don’t cut or program car keys)

Why multi-structure properties need a plan

The most common request we get in Frontenac isn’t a lockout — it’s a homeowner who’s ended up with three or four different keys for the house, the garage, the gate, and the pool house, usually because each was installed at a different time by a different contractor. We can rekey the whole property to a single master key so one key opens everything you’re supposed to have access to, while keeping separate access for anything you want to restrict, like a guest house or a home office.

Gated entries add their own wrinkle. A keypad or lock on a driveway gate sits outside year-round, so it takes more weather exposure than an interior door ever will. If yours has gotten stiff or slow to respond, that’s usually the mechanism rather than the whole gate needing replacement.
