How It Works

Help is four simple steps away

No call centers, no runaround. From the moment you reach out to a guaranteed finish.

01

Call or Book Online

Tell us what's going on. We confirm your location and the exact, all-in price on the spot.

02

A background-checked Sentinel tech is dispatched with a live ETA — 15 minutes on average.

03

Job Done Right

Damage-free work, clean install, and a full walkthrough of any new smart hardware before we leave.

04

Guaranteed & Backed

You're covered by our 90-day workmanship warranty and manufacturer parts warranties. Sleep easy.

The No-Scam Promise

Locksmith horror stories end here

The industry has a trust problem. We built our business to be the opposite of everything you've been warned about.

Locked-In Price Before We Start

You hear the exact, all-in price on the phone and again in writing before any work begins. The number we quote is the number you pay — no surprise fees at the door.

Real Local Technicians

We're a licensed local shop, not a lead-gen call center that dispatches unvetted contractors. The person who answers dispatches a Sentinel employee.

Damage-Free Guarantee

Our entry methods are non-destructive by default. If a job ever requires drilling, we tell you why and what it costs before we touch your door.

90-Day Workmanship Warranty

Every install and repair is backed by a 90-day workmanship warranty, plus full manufacturer warranties on all parts and smart hardware we supply.

Every quote is locked in before we start. Zero surprises, guaranteed.

Who We Help

Built for every kind of home & host

Whether you own, rent, host, or manage — we've got a security plan that fits.

Homeowners

Upgrade to high-security or smart locks, rekey after losing keys, and harden every entry point.

New Move-Ins & Renters

Just got the keys? Rekey every lock so previous owners, agents and contractors can't get in.

Airbnb & Short-Term Hosts

Self-check-in keypads and time-limited guest codes that expire automatically between stays.

Property Managers

Master-key systems, rapid turn-over rekeys, and smart access across your entire portfolio.

Certified to install & service

Locked out at 1am with a newborn in the car. They answered instantly, quoted the exact price, and had me inside in 20 minutes with zero damage to the door.

Installed biometric deadbolts on three doors and tied everything into HomeKit. The tech walked my whole family through the app. Genuinely the cleanest install I've seen.

Cedar Park, TX · Smart Lock Install
After a break-in they reinforced the frame, replaced the locks, and even gave me documentation for my insurance claim. Felt safe in my own home again the same night.

The security audit found two windows I never thought about and a smart camera with a default password. Worth every penny for the peace of mind.
