Certified installation centers in Seattle
Sorted by how far they are from the center of Seattle. 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.

The fees nobody quotes you over the phone
These are charged on top of the three above, and they are where a cheap-looking Washington quote turns expensive.
| Fee | Amount |
|---|---|
| Typical total for one year, as the legislative audit states it | about $2,700 |
| With high-risk insurance and court fines | around $5,000 |
| Financial assistance for low-income drivers | up to about $1,400 reimbursed; the $21 monthly fee is waived |
| Device transfer to another vehicle | assistance up to $100 a year |
- Figures come from the legislature’s own audit of provider fee schedules, not from vendor marketing.
- Calibration is required at least every 65 days.
What Washington requires
Washington issues a separate license class for this — the Ignition Interlock Driver License. You may apply at any time, including straight after arrest and before the revocation begins, and it lets you drive normally as long as every vehicle you drive has a device. Work vehicles count too if your employer owns, leases or maintains them.
- First offense: For the remainder of the suspension, revocation or denial — you may apply at any point, including immediately after arrest
- Lockout threshold: Set by the device standard adopted by the Department of Licensing
- Program run by: Washington State Department of Licensing
Why Washington 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. King County runs at or below the Washington average — the requirement is set state-wide regardless. 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 Seattle
Where can I get an ignition interlock device installed in Seattle, WA?
We index 1 certified installation point in Seattle, run by Intoxalock. 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 Washington?
Washington publishes its own figures rather than leaving it all to vendors: up to $250 to fit the device and $150 to $191 a month while it stays on the car. Removal is billed separately at the end of the term.
Can I drink one beer and still start the car in Washington?
Almost certainly not. Washington 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.
