Colorado Western Slope Interlock                                 (970) 874-9180     

Install, Calibration, Transfer and Removal

Calibrations are $20 for two months service.  It only takes about 5 minutes to complete.

At the time of installation, our techs will have you watch a video and show you how to use the breathalyzer.  

An ignition interlock device* integrates breath alcohol testing with your vehicle’s ignition system. Prior to starting your vehicle, you will need to submit a breath sample into the handheld portion of the device that tests for the presence of alcohol. If your Breath Alcohol Concentration (BrAC) is below Colorado’s ignition interlock limit (0.025), your vehicle will start. If alcohol is detected, your vehicle will not start until a passing sample has been provided.

To get started contact Intoxalock at (877) 777-5020 or visit


There are all the forms and information you need for the interlock through  Intoxalock or you may stop by CWSI and we would be more than happy to assist you.
