Worried someone could pick your lock - or copy your key without asking?

High security locks are cylinders engineered to resist picking, drilling, and bump attacks, paired with restricted keyways so blanks aren't sold at hardware stores or cut at a kiosk - you control who gets a working key. Express Local Service (Texas Locksmith License B19775) supplies and installs genuine high security hardware in San Antonio, matched to your door rather than sold by the box, and we explain the real difference between marketing-grade and true Grade 1 security before you spend a dollar.

What real high security hardware actually means

Not every lock labeled "high security" earns it. The protections that matter are pick and bump resistance from sidebars and security pins, drill resistance from hardened steel inserts and ball bearings, and ANSI/BHMA Grade 1 ratings for cycle life and forced-entry strength. The piece most people overlook is key control: a restricted or patented keyway means duplicate blanks are not on the open market, so a tenant, contractor, or ex can't quietly run a copy. We register your keyway and document who holds authorization.

This is a step up from a standard lock change, which swaps in new but ordinary-grade hardware. If your goal is controlling who already has a working key rather than upgrading the cylinder itself, a rekey may be the smarter, lower-cost fix - and we'll tell you which one your situation actually calls for.

What to tell us when you call
List the doors you want hardened (front entry, side door, server or storage room), the brand stamped on your current locks if you can see it, and whether your real concern is break-in resistance, key copying, or both. That lets us scope the right keyway and grade and quote it before any work begins.

What makes a lock 'high security' versus a regular deadbolt?▾
True high security cylinders add pick- and bump-resistant pinning, hardened steel inserts that resist drilling, and an ANSI/BHMA Grade 1 rating for strength and durability. Just as important, they use restricted keyways so the blanks aren't sold openly. A regular deadbolt has none of those layers, even if the package says 'maximum security.'
Can someone still copy my key at a hardware store or kiosk?▾
No - that's the point of a restricted keyway. The blanks are not stocked on the open market, and cutting requires authorization tied to your registered key system. We document who's allowed to request a copy, so a tenant, contractor, or former employee can't quietly make one.
Do I need high security locks, or would a rekey or lock change be enough?▾
It depends on your goal. If you just need old keys to stop working, a rekey or a standard lock change is usually enough and costs less. High security hardware is worth it when you want genuine pick and drill resistance plus strict key control. We'll tell you honestly which one fits - we don't upsell for the sake of it.
Are you licensed to do this work, and will I know the price first?▾
Yes. We hold Texas Locksmith License B19775, and every high security job is scoped around your door type, the grade and keyway you need, and the number of cylinders - then quoted before we pick up a tool. You'll know the price before any work begins. No published price list, because the right hardware depends on the door.
