Certified installation centers in Centennial
Sorted by how far they are from the center of Centennial. Where two providers work out of the same garage, we list the garage once with both names, and we include nearby towns when their center is closer than one of your own.
Compiled from providers’ own public location directories and deduplicated to unique physical places (how we build this index). Listing is not an endorsement, and no center pays to appear.

What Colorado requires
Colorado uses the interlock for early reinstatement: instead of sitting out a revocation, you fit a device and drive from the first day the action goes active. What you trade is time on the device — nine months at a lower reading, two years above 0.15% or after a refusal.
- First offense: 9 months for a first offense below 0.149% (running alongside the revocation); 2 years at 0.15% or higher, and 2 years automatically for refusing the test
- Lockout threshold: Set by the approved device standard adopted by the Department of Revenue
- Program run by: Colorado DMV (Department of Revenue)
Why Colorado orders these devices
An interlock order is not a judgment about you personally — it is what the state does with every case of this kind, and the reason sits in the crash record.
Source: NHTSA Fatality Analysis Reporting System, 2020–2022. The count covers fatal crashes where police recorded that a driver had been drinking, which is narrower than the federal 0.08 BAC measure and therefore understates the real figure. Arapahoe County runs above the Colorado average, which is part of why the interlock requirement here is enforced the way it is. What the device changes is measurable too: a car fitted with one cannot be started over the limit, which is why the order attaches to driving privileges rather than to the sentence.

Interlock questions in Centennial
Where can I get an ignition interlock device installed in Centennial, CO?
We index 2 certified installation points in Centennial, run by Smart Start, Guardian Interlock, LifeSafer. Addresses are listed above. Book with the provider your paperwork names, not the nearest one — a device approved in one state is not automatically approved in the next, and switching brands mid-term means a second installation fee.
How much does it cost to have an ignition interlock device installed in Colorado?
Colorado does not publish a price, so the honest answer is the national one: NHTSA puts installation at $70 to $90 and monitoring at about $70 a month, roughly $3 to $4 a day. Quotes in Centennial will sit around that unless the provider is charging for something the state does not require.
Can I drink one beer and still start the car in Colorado?
Almost certainly not. Colorado does not print one fixed number in the statute — the level is set by the certifying agency in the device standard, typically between 0.02% and 0.025% BAC, far below the 0.08% driving limit. The device is not testing whether you are impaired, it is testing whether you drank. One drink shortly before a test is enough on most programs, and the fail is recorded whether or not you try again.
What does an ignition interlock device do?
An ignition interlock is a breath-alcohol tester wired into your car ignition. You blow into it before starting the engine; if your breath alcohol is above the state threshold, the engine will not start.
While you are driving, the device asks for rolling retests at random intervals. Every sample, skipped test, and lockout is recorded and sent to the agency monitoring your case.
