If your vehicle stalls, turn your key off. Within 2-4 seconds, your Intoxalock will recognize that your vehicle is off and start a 1-3 minute countdown. You may try to restart your vehicle without submitting a breath sample as soon as the countdown appears. If your car won’t start, you’ll need to check the health of your battery by holding down device button for 5 seconds (learn about Intoxalock’s exclusive sleep mode feature to ensure you are conserving your battery properly). You can also test your car radio or lights to see if your battery is charged. If your battery health is good, contact our excellent customer support team to troubleshoot potential IID problems.
