How it works
From your call to back inside
Call or text
Tell us what happened and where you are. We ask a couple of questions about the lock or vehicle so we arrive with the right gear.
Get a price
You hear the price and an honest arrival window before you agree to anything. No “we’ll see when we get there.”
We come to you
The van carries key machines, blanks, programming tools and common hardware, so most jobs finish in one visit.
Job done right
We open it, rekey it, or replace it — and we tell you plainly which of those you actually need.
Locked out? Call and we’ll give you a price and an arrival time.
We carry the key blanks, programming tools and common hardware in the van — so most jobs are finished on the first visit.

Common questions
Answers before you call
How fast can you get here?
Most calls in the West Chester, Mason and north Cincinnati area are reached within the hour. Call and we will give you an honest arrival window before you commit — not a guess.
Do you charge before you start the job?
We give you the price up front, before any tool comes out of the van. If the price changes because the job turns out to be different than described, we tell you first and you decide.
Are you open on weekends and holidays?
Yes. We answer seven days a week, 7am to 11pm, weekends and holidays included.
Can you make a car key if I lost every key?
In most cases yes. We cut and program replacement keys and fobs on site for most makes and models, so there is no tow to the dealership.
