Novak Lock & Security in South Dakota
Novak Lock & Security has been handling locks, keys, and access systems for South Dakota homeowners since 2002. We’re part of the Haven family, which means every job we do across the state starts with a written price and ends with a documented record. No exceptions. Our technicians arrive in uniform, with background checks complete, and they work to a published standard you can hold us to. Since 2002, we’ve installed or serviced over 60,000 locks and systems, and every single one began the same way: a firm number agreed before we dispatched anyone.
Why South Dakota Homeowners Choose Novak Lock & Security
The locksmith trade has a reputation problem, and South Dakota isn’t exempt from it. The familiar story is a quoted price that triples at the door and a technician who won’t leave until you sign. We built Novak Lock & Security to be the opposite of that. Our dispatcher quotes a firm price on the phone and the technician arriving at your door is not permitted to change it. That rule has been in place since 2002 and it’s not a policy, it’s a contract term. When a South Dakota homeowner calls us about a rekey, a deadbolt install, or a lockout, they know the number before anyone starts driving.
We work on the full spectrum of hardware: Medeco, Mul-T-Lock, Abloy, Baldwin, Schlage, and standard entry-grade locks. Every job, from a single cylinder rekey on a 2018 starter home in a newer development to a full high-security retrofit on a mid-century property, gets the same treatment: a written scope, a documented photo record left with you when we finish, and a 365-Day Done Right Promise. If it isn’t right, we return and make it right. We don’t ask you to trust us. We hand you the paperwork that lets you verify us.
Backed by the Haven Family

Haven was formed in 1998 with a simple bet: buy good home-service companies and leave them alone, while holding every one to a published standard. That standard, The Haven Standard, is five clauses: written price before work starts, a real arrival window with a named technician, licensed and insured crews with background checks, photo evidence on every visit, and no upsell at the door. Every Novak Lock & Security job in South Dakota operates under those five clauses. We’re independently owned and operated, and we carry the Haven name because we agreed to be held to it.
