What Is an IID?
An Ignition Interlock Device (IID) is a breath-testing device installed in your vehicle that prevents the car from starting if alcohol is detected. Courts and DMVs commonly require IIDs as a condition of license reinstatement following a DUI/DWI conviction.
As an authorized SmartStart service center, Keystone handles installation, calibration, monitoring reports, and removal — making it easy to stay compliant throughout your program.
Stay on the Road
An IID allows you to keep driving — legally — while meeting your court or DMV requirements. We make the process as simple as possible.

FAQ
Your court or DMV will specify whether an IID is required as part of your DUI/DWI sentence or license reinstatement. Contact your attorney or the court clerk if you're unsure.
Most installations are completed the same day at our Greensboro service center. Please bring your vehicle and all court/DMV paperwork to the appointment.
Calibration is typically required every 30–60 days depending on your program. We'll remind you when your calibration is due and the process is quick — usually under 30 minutes.
SmartStart IIDs are installed by certified technicians using approved methods that do not damage your vehicle's electrical system. The device is fully removable at the end of your program.
Missing a calibration can put your license and program compliance at risk. The device may lock you out if calibration is overdue. Contact us immediately if you can't make a scheduled visit.
No long-term contract is required. Your lease is month-to-month. Once your court or DMV program is complete and you receive authorization for removal, we'll remove the device at your final visit.
