Ignition Interlock Calibration

Driving with an ignition interlock device does require some changes to your regular driving routine, and one of those changes is staying on top of the service and calibration requirements.

Your interlock device will need regular calibration, in which service technicians download the data from your device and make sure it’s working correctly. While your device will always alert you to upcoming service, you may still be wondering what interlock calibration entails and how to find an ignition interlock calibration location near you.

How Often Will My Device Need Calibration?

It depends on your specific interlock requirements, but in general, you can expect to calibrate your device every 30 to 60 days. With RoadGuard Interlock you don’t have to worry about keeping track of your appointments, because your ignition interlock device will remind you of your upcoming appointment.

What Happens at an Ignition Interlock Calibration Service Appointment?

When you visit your nearest service center for a calibration appointment, the service technicians will do the following:

  • Download the data on the interlock device
  • Log the odometer reading on your vehicle
  • Inspect your device, including wiring and connections, to make sure it’s working properly
  • Look for any evidence of tampering
  • Calibrate your interlock device, so it continues to test accurately
  • Schedule your next appointment

How long does interlock calibration take?

With RoadGuard Interlock, we get you in and out as quickly as possible! Calibration appointments are usually around 20 minutes or less.

What Happens if I Miss a Calibration Appointment?

Your device will always alert you when there’s an upcoming appointment of any type, including calibration. When you receive an alert, you need to ensure you show up for your appointment promptly. If you don’t, your device will go into lockout mode, and you’ll be unable to drive.

Your future appointments will be scheduled in advance, at the prior service appointment.  Look out for appointment notifications that way, you won’t miss any appointments and that you don’t face any lockout periods.

What Leads to Early Servicing?

Sometimes, you might receive a service alert earlier than your normal range of 30 to 60 days. This can happen for several reasons, and not all of them are interlock violations.

  • The memory on your interlock device may be full and need to be downloaded
  • You had your vehicle serviced — don’t forget to keep receipts from your repair shop to bring to your next calibration appointment
  • You skipped or failed a random retest — you’ll have a set period to visit a service center before facing a lockout
  • You failed an initial breath test
  • The device recorded an attempt at tampering or bypass — these are serious violations

Scheduling frequent service appointments is a necessary part of driving with an interlock device. Keeping those appointments whenever you receive a service alert will help you stay on the road and prevent a device lockout. If you are locked out due to a missed service appointment, your device will display a countdown prior to locking out.
