Price: 299.0 USD
Availability: InStock

Keepr Drive is a small breathalyzer that connects to your car's ignition. One breath, a reading in seconds, and the car starts when the reading is under the limit you set. No alarms. No lectures. No guessing.

Is it right for you?

Backed by 35 years in alcohol detection. Installed by certified technicians. Keepr Drive is available in select U.S. markets. Device shown is a rendering; actual product may vary.

Three things happen before every drive.

Tap a step, or just watch.

Lid open. Blow steadily for a few seconds.

1

Open the lid and blow steadily for a few seconds. The mouthpiece tucks under a soft-touch cover, so closed, it looks like a case for earbuds — not a breathalyzer.

Test at the ignition, on a schedule, or on demand — in the car, at dinner, anywhere.
2

A fuel-cell sensor returns breath alcohol concentration in seconds. The number lands on the device, in the app, and on the phone of anyone you've chosen to share with.

Every result is time-stamped and kept in the app, so you can look back at any week.
3

Under the limit you set, the engine is yours. Over it, the car stays put — quietly. No horns, no flashing lights, no report to anyone but the people you chose.

You decide the limit, and you can change it from the app whenever you like.

Where it fits

Four seconds, wherever the day goes.

Living room, kitchen counter, dinner out, the morning after. The Keepr check fits wherever the day goes — a quick reading, then on with it.

A man at home in a green shirt holding up the Keepr device reading 0.000 — **Living room, 7:10am**Reads 0.000, grabs the keys

A woman at a kitchen counter with the Keepr device beside a glass of water — **Kitchen counter, 6:40pm**Lives next to the keys

A man in a restaurant holding the Keepr device as the reading climbs — **Reading: 0.030**The car waits. So does he. No argument.

A woman at a bar showing the Keepr device to the camera — **Before the second round**Checks first, decides second

A man in a gym with a towel over his shoulder talking to the camera — **Saturday, after the gym**Last night is last night. The car checks anyway.

The Keepr app

A record when you want it. Privacy when you don't.

A tool you chose, not one you were handed. Every test lands in the app. Nothing is sent to a court, a state or a monitoring company. Look at a week and see the pattern. Share it with the people you choose, and no one else.

A photo with every test: The camera captures who took the sample, so each result comes with a face and a time attached.
Shared only when you say: Your test results are shared only with people you've authorized to see them.
Not clear yet? Retest.: A reading over your limit isn't a lockout. It's a result. Wait a few minutes and take it again. The car waits with you.

Two roles, one account

Keepr Drive takes two.

You can set up your account with an admin who manages settings and one or more drivers who take tests.

An admin can be a partner, sibling, or friend who helps drivers stay accountable.

Admin Holds the settings Who tests, when the car asks, what reading starts it. Sees the results that are shared with them.
Driver Takes the test Blows, reads, drives. Results stay private unless marked Shared. One person can be both, but never alone.

You set the rules. The car keeps them.

Three decisions, made once in the app: who tests, when the car asks, and what reading starts the engine. Change any of them as life changes. Flip a switch and watch the rule rewrite itself.

Admins and other drivers don't need to take a test to start the car.
Off for the school run, on for Saturday night.
Results are private by default. Share them only with the people you add.

Built for the people who'll actually use it.

For your teen or college kid

You trust them. You just don't trust the night. Keepr Drive turns “text me when you're home” into something you can count on — without a speech every time they leave.

You set the limit. Results on your phone. Testing off for the school run, on for Friday night.

For someone you love

Helping without hovering is hard. Keepr Drive makes the check automatic, so you're a partner in it — not the one guarding the keys.

Private by default. Share exactly what you both agree to, and nothing more.

For you and your passengers

The honest answer to “am I fine?” is usually “not sure” — and nobody in the passenger seat wants to be the one to ask. Keepr Drive settles it before you leave the lot. Blow, read, decide, and the night ends on your terms.

Finished an interlock program? Keep the backstop. Lose the horns, the retests and the reporting.

Smarter than guessing. More freedom than an interlock.

A handheld breathalyzer gives you a number and then trusts you to act on it. A court-ordered interlock acts on it, but on the court's terms, with a horn and a report to the state. Keepr Drive is the version you'd actually choose.

Why it matters: in 2023, 12,429 people died in alcohol-impaired crashes in the U.S., and drivers aged 21 to 24 had the highest rate of impairment in fatal crashes. Keepr Drive exists so “probably fine” never has to be the deciding factor. Source: NHTSA.

Is Keepr Drive right for you?

Four quick questions. There are no wrong answers — just a clearer picture of what you'd actually get out of it.

Built on 35 years of alcohol detection.

Keepr is part of Mindr — 35 years of alcohol detection, and the same fuel-cell sensor technology trusted in monitoring programs across the country. This is that technology, redesigned for people who were never ordered to use it.

Questions people ask before they buy.

Something else? Send us a note and we'll get back to you.

What exactly is Keepr Drive?

Keepr Drive connects the Keepr breathalyzer to your car's ignition. Before the car starts, the driver provides a breath sample. Under the limit you've set, the engine starts. Over it, the car stays put until a passing sample comes through.

Is this a court-ordered interlock?

No. Keepr Drive is voluntary, and it isn't a substitute for a court-ordered IID. There's no state reporting, no horns or lights, and you can pause or cancel whenever you like. If you've finished an interlock program and want to keep a backstop without the hassle, this was built for you.

Does the driver have to test every single time?

Only if you say so. Choose which drivers test and when — every drive, nights and weekends, or custom hours. Turn it off for the school run and on for Saturday night, straight from the app.

We share the car. Does that work?

Yes. Each driver has their own profile and rules. Drivers who aren't required to test just get in and go.

Who sees the results?

Only the people you choose. Results are private by default and can be shared in real time with anyone you add — a parent, a partner, a sponsor. Every result is time-stamped and kept in the app.

How accurate is it?

Keepr uses a fuel-cell sensor — the same class of technology used in professional alcohol monitoring — with a detection range of 0.000–0.400% BrAC and ±0.005 accuracy at the low end, where the decisions actually get made. Results come back in seconds.

How does installation work?

Keepr Drive is installed by a certified service-center partner so it's connected correctly. You choose the shop and an appointment time when you order. Drop the car off, pick it up when it's done. Installation starts at $200, paid at the shop; the final price depends on your vehicle.

Can I set it up for just me?

You'll need one other person. Every Keepr Drive account has an admin, who holds the settings, and a driver, who tests. If you're doing this for yourself, pick an accountability buddy: a partner, a sibling, a sponsor or a friend. They hold the rules and see only the results you choose to share.

What does it cost after the first three months?

Your first three months of Keepr Drive are included with the $299 system; installation is paid separately at the shop. After that it's $49.99 a month, or 10% less on an annual plan. Cancel any time with no fees. The breathalyzer is yours either way.

Where is it available?

Keepr Drive is available in select U.S. markets, installed by certified service centers in dozens of states. Enter your ZIP to see the shops closest to you. If there isn't one nearby yet, tell us your state and we'll let you know the moment Keepr Drive is near you. You can start with the Keepr breathalyzer on its own today.

Decide once. Then just drive.

Order today, pick your shop at checkout, and every drive from here on starts with a clear reading and ends with nothing to explain.
