SERIES: ‘Mouth Closer’ Meaning on My Ignition Interlock

Did you receive a MOUTH CLOSER reading on your Ignition Interlock screen? Adjusting how you take your tests is very easy, however, you can always call our Customer Care Center at (800) 831-3299 for assistance.

Let’s go over what MOUTH CLOSER means. We’ll also tell you what you can do to fix how you test with your device.

What MOUTH CLOSER Means

MOUTH CLOSER indicates that your lips are not completely sealed around the mouthpiece. It could also mean your lips are not close enough to the base of the mouthpiece. The device’s sensor cannot detect that your mouth is close.

The MOUTH CLOSER result is an abort-type message from your Ignition Interlock. Abort test results mean your device did not get a sufficient reading from your breath. Keep in mind that aborts will not mean failed tests!

How Do I Fix My Testing Pattern?

After receiving a MOUTH CLOSER result, make sure your mouth is more firmly around the mouthpiece as you take your next test. You can try to test again when the device reads BLOW on its screen. If you are still having trouble, our team can assist you at (800) 831-3299. Make sure to choose over the phone ‘current customer,’ and then ‘product-related support.’
