FLEX Ignition Interlock FAQs

Below you will find answers to a list of common questions for the FLEX™ Ignition Interlock program. To simplify the list below, you may sort the questions by using the subject links located immediately above the list.

You can always ask our service technicians for instructions at your installation appointment. You can also find online training videos with step-by-step instructions for using your IID.

You can access the Menu by selecting the middle button. Select the top button to move up and the bottom button to move down. Click here to watch the instructional video.

“Blow harder” means that your breath sample did not last long enough for your test to register. “Hum stronger” means that you began humming either too late or too soon. It might also mean that your hum was not strong enough to register. “Blow softer” means that your breath sample was too strong. “Don’t inhale” means that you might have inhaled while your lips were still around the mouthpiece, therefore sucking air into the unit. “Abort tamper” means that you covered the vent on the back of your IID while blowing. “Mouth closer” means that you’ll need to hold the Ignition Interlock Device more firmly against your mouth to avoid letting the device pull away as you blow. To complete your test successfully, you will need to blow steadily for the full time of your test. Keep both your breath volume and your hum even during testing.

“Abort lock” means that you have exceeded the allowed number of aborts during a 15-minute period and will need to wait until the countdown completes before you attempt another test.

“Initial BAC” means that the device has detected alcohol during your initial test. “RRTEST” means that the device detected alcohol during your rolling re-test. “CIRC” means that circumvention has occurred in the form of you disconnecting your handheld while driving. “Templock” means that your test detected a low level of alcohol and your device has been temporarily locked based on your state’s limits. “RRSkip” means that a rolling re-test skip has occurred because you did not take a test when prompted after your initial test. Even if you are at your destination, you must test again if your device prompts you to do so.

Yes, you can provide a breath sample without a mouthpiece.

Yes, you can wash your mouthpiece and place it back on for reuse. However, only use a mild soap-and-water solution to clean your mouthpiece, then rinse it thoroughly. Give it a few minutes to dry before putting it back on the device. It is important not to use an alcohol-based or chemical-based cleaning solution.

The laws vary from state to state, so it’s very important to check with your state authority or with Smart Start before you disconnect your handset.

If your state allows, your handset can be quickly disconnected at the silver push-pull connector. Just squeeze the connector body and pull back on the outer sleeve to unlatch. To reconnect and lock the handset, simply push the plug into the receptacle.

Watch how to disconnect your handset here.

Your FLEX is built to withstand extreme temperatures. However, if your state allows it, you can disconnect the handset so you can take it inside. Doing this will speed up the warmup times in cold weather and also keeps your device safely with you.

When the device displays “PAYMENT DUE,” this means a payment must be made to bring your balance up to date. You will be required to bring the vehicle to a service center for service where your payment can be collected. Payment can be made on the Client Portal App. However, you will be required to return to the service center for service if you do not have a modem installed.

You can check by accessing the menu through the FLEX handset, or by checking the Client Portal app.

Here’s a short video on how to navigate the menu on the FLEX handset.

Payments can be made on the Smart Start Client Portal app. If you have not received the registration link from our Customer Care Center, please contact (800) 831-3299 where an invitation will be forwarded to your email on file.
