Certified installation centers in Decatur
Sorted by how far they are from the center of Decatur. 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 it costs in Decatur

|---|---|---|
| Installation | $75 | the same cap applies to de-installation or a secured deposit |
| Monthly | $75 | inspection and recalibration every 30 days |
| Removal | $75 | Taking the device out at the end of your term |
State-capped maximum — a provider may not charge more · Rules of the Department of Driver Services, Subject 375-3-6 — Ignition Interlock Devices · checked 2026-08-23
- A provider may not charge an installation or monitoring fee before actually providing the service.
What Georgia requires
Georgia routes you through a limited driving permit rather than a flat suspension. For a second DUI within five years the interlock permit requires three things before it is issued: proof the device is already installed on every vehicle you will drive, a certificate from a DUI risk reduction program, and authorization from the court that handled the charge.
- First offense: Set by the permit rules: a second DUI within five years requires the interlock permit under O.C.G.A. 40-5-63(a)(2), and anyone excused from the device on financial hardship grounds gets no limited permit until the required period is served
- Lockout threshold: Set by the device approved by the Department of Driver Services
- Program run by: Georgia Department of Driver Services, with court authorization for repeat offenses
Why Georgia 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. DeKalb County runs above the Georgia 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 Decatur
Where can I get an ignition interlock device installed in Decatur, GA?
We index 3 certified installation points in Decatur, run by Intoxalock, Smart Start. 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 Georgia?
Georgia publishes its own figures rather than leaving it all to vendors: up to $75 to fit the device and up to $75 a month while it stays on the car, and the monthly figure is a ceiling an approved provider may not exceed. Removal is billed separately at the end of the term.
Can I drink one beer and still start the car in Georgia?
Almost certainly not. Georgia 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.
