Lock Replacement in St. Louis, MO: Deadbolts, Smart Locks, and Rekeying

Lock replacement in St. Louis, MO is the move you make for security, convenience, or both — a new deadbolt after a move, a smart lock so you stop hiding a key under the mat, a rekey so the old tenant's key doesn't work anymore. Here's what we install, when to rekey vs. replace, and how we make sure the new lock actually fits the door it's going into.

What we install

• Deadbolts — single-cylinder, double-cylinder for glass doors
• Handlesets and keyed entry knobs
• Smart locks — keyed, keypad, and app-connected (Ring, Nest, August)
• Rekeying existing locks so old keys no longer work
• Door hardware — levers, backplates, and strike plates

Full scope on our doors, windows and locks page.

Rekey vs. replace

If the lock body is sound and you just want to invalidate old keys, rekeying is the cheaper move — we re-pin the cylinder so a new key works and the old ones don't. If the lock is worn, the finish is dated, or you want to upgrade to a smart lock or a higher-security deadbolt, replacement is the call. We carry both options and tell you which fits the situation.

Smart locks

A smart lock is a convenience upgrade — codes instead of keys, remote locking, and entry logs. We install them, connect them to your home network, and confirm the door still latches and aligns (a misaligned door is the number one reason smart locks fail to lock remotely). We install Ring, Nest, August, and keypad deadbolts.

The strike plate and the deadbolt throw

A new deadbolt is only as secure as its strike plate and the door frame behind it. We install the deadbolt with a reinforced strike plate and long screws that reach the framing, and we confirm the bolt throws fully into the strike — a deadbolt that only throws halfway because the door is out of alignment isn't doing its job. We'll fix the door alignment too if that's the issue.
