About Us
What Our Customers Are Saying
"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."
"Panic bar and a master key system for a small office. Clean install and clear paperwork showing which key opens what."
"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."
"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."
"File cabinet key that had been lost for a decade. He made one from the lock itself in about fifteen minutes."
"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."
"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."

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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
