QuickStart Interlock does require an appointment. This is to insure an efficient and timely experience. Typically we can get you in within a day or two and sometimes can do same day appointments. Installation of an ignition interlock typically takes between 45 and 60 minutes, depending on the make and model of the vehicle. Push button start or keyless ignition vehicles, will typically take 60-90 minutes. During the installation process our representative will train you on the use of the device, as well as, the “do’s and don’ts” of the Arizona Ignition Interlock program. You must be present at time of installation.
