"The deadbolt had been mounted crooked by whoever lived here before and had stuck for years. He redrilled and reset it properly rather than just swapping the hardware."

Parts we install
Premium, Long-Lasting Lock Parts
The part decides how long the repair lasts. Here is what we fit, and what the cheap version costs you later.
Lock Cylinders
The cylinder is the part your key turns and the part an intruder attacks. Everything built around it is really just housing.
What we install
We install cylinders with anti-pick pin stacks, hardened anti-drill inserts, and a restricted keyway so copies cannot be cut at a hardware kiosk.
What other companies fit
A basic five-pin cylinder with standard drivers and a common keyway is what ships on most doors. It rakes open quickly, drills in seconds, and anyone can copy the key.
Deadbolts
Deadbolt grade is a real, measurable standard, set by cycle testing and by how much force the bolt takes before it fails.
What we install
We install Grade 1 deadbolts with a full one inch throw and a hardened insert in the bolt, tested to the highest cycle and impact levels in the standard.
What other companies fit
Grade 3 residential deadbolts are the builder default. Shorter throw, softer bolt, lighter internals, and they are tested to a fraction of the same force.
Strike Plates
Most kicked-in doors do not fail at the lock. They fail at the jamb, where the strike plate is held by short screws in soft trim.
What we install
We fit reinforced box strike plates with three inch screws that reach the wall framing behind the jamb, so force spreads into the structure of the house.
What other companies fit
The standard plate is thin stamped steel with short screws that bite only the trim. One solid kick splits the jamb and takes the entire lock with it.
Smart Locks
A smart lock is still a lock. The mechanical half underneath the keypad is what actually keeps the door shut.
What we install
We install smart locks built on a graded mechanical deadbolt, with a real key override, encrypted credentials and a low battery warning well before it dies.
What other companies fit
Cheap keypad locks are built on plastic internals with an ungraded bolt. The keypad wears until the used digits are obvious, and a flat battery locks you out entirely.
Key Blanks
A duplicate key is only as accurate as the blank it was cut from. Bad blanks are the reason a brand new copy sticks in the lock.
What we install
We cut on nickel silver or brass blanks matched to the manufacturer specification, on a calibrated machine, and we test every key in the lock before we leave.
What other companies fit
Thin aftermarket blanks cut on a worn machine come out off by enough to bind the pins. The key wears the lock, snaps in the cylinder, or simply stops turning.

What Our Customers Say
Homeowners in every market we serve, in their own words.
★★★★☆
"Got me back in and the price was fair for the hour. He arrived closer to forty five minutes than the twenty he estimated, which feels long standing outside, though he was honest that traffic was the problem."
★★★★☆
"Rekey was done properly. One of the keys he cut was slightly stiff in the back door and I had to call him to swap it, which he did without any fuss."
★★★★☆
"Does good work and knows his trade. Taking a card payment was a bit of a production, so have another option handy."
★★★★★
"Rekeyed every lock the day after we closed. Six doors, all matched to one key, done in about ninety minutes."
★★★★★
"Told me over the phone that what I needed was a five dollar part from the hardware store, not a locksmith. I called him back a month later for real work because of that."
★★★★★
"Used them at two different addresses now. Both times the tech was in uniform, introduced himself and showed ID without me having to ask."
★★★★★
"Key snapped off in the deadbolt. He got it out without wrecking the cylinder, which I did not think was going to be possible."
★★★★★
"Locked out at eleven at night with a kid asleep in the back seat. He was there in twenty five minutes, had the door open in under two, and did not do the thing where the price goes up once he is standing in front of you."
★★★★★
"File cabinet key that had been lost for a decade. He made one from the lock itself in about fifteen minutes."
★★★★★
"Quoted a price on the phone and honored it. After the last locksmith I called, that alone is worth writing down."
★★★★★
"Panic bar and a master key system for a small office. Clean install and clear paperwork showing which key opens what."
★★★★★
"Installed a smart lock and actually set up the app and the codes with me instead of leaving me to work it out from a leaflet."
★★★★★
"Safe had been in the house when we bought it and nobody knew the combination. He opened it without damaging it and reset it while he was there."
★★★★★
"Programmed a transponder key for an older car that the dealership wanted an absurd number for. Same key, fraction of the price, twenty minutes in my driveway."
