Understand the reputation of your contractor
Not all shops are the same!
Your interlock provider will most likely subcontract out its services through one of the businesses listed above. It is important that you are familiar with the reputation of that shop and how they will treat you for the duration of your interlock program. For many shops, interlock services are secondary to what they do and they will have very strict policies regarding monthly services or repairs if necessary. Ask them questions to find out how willing they are to deal with you. For many shops, the standard answer is call your provider.
