Lock Installation in St. Louis

New Locks, Installed Right

A good lock badly installed is a weak lock. A deadbolt that doesn’t fully extend, a strike plate held by short screws, or a latch that rubs every time you close the door all cost you security. Prime Locksmith Services installs new locks for homes and businesses across St. Louis and fits them properly, so they lock cleanly and stand up to a kick or a pry bar.

We install deadbolts, knob and lever sets, handle sets, patio door locks, keypad locks and high-security cylinders from brands such as Schlage, Kwikset, Medeco and Mul-T-Lock. We can bring the hardware, or install locks you have already bought.

For lock installation in St. Louis or any job for a residential locksmith in St. Louis, call (314) 745-4590.

How We Install Your Locks

From choosing the hardware to a door that closes smoothly.

Tell us about the doors

Which doors, what lock you have now, and what you want: keyed, keypad or high security.

Hardware and price

We recommend hardware that fits your door and budget, and quote it upfront.

Measure and prep

We check the backset and bore holes and adjust the door so the bolt throws fully.

Install and reinforce

New lock, a solid strike plate and long screws into the door frame.

Key alike and test

All new locks can be keyed to one key. We test every one before we leave.

The cheapest upgrade: longer strike screws.

Many front doors are held shut by strike plate screws that only reach the thin trim. Three-inch screws into the wall stud make the door far harder to kick in, and we fit them with every deadbolt we install.

Prime Locksmith Services’ own price ranges from our pricing page. The final price depends on the hardware you pick.
