Good morning Gail,
I'm Doug, and I'm very sorry to hear of your grandson's situation. My goal is to provide you with excellent service today.
I do empathize with the situation that your grandson is in, and it is wonderful that you are willing and able to assist him in meeting the court imposed obligations.
If he has a court date set to go and see about clearing the warrant, that is great. If there is not a court date set yet, then he may have to first post a bond to have the warrant lifted.
He may contact the criminal court clerk’s office at the courthouse and ask what the amount of bond is for the warrant.He will then need to post the bond on the bench warrant, or arrange for the bond to be posted.The bond is often between $500 and $1,000, cash only, and then he will get another court date to appear to answer to the underlying charge.
As he is not in the state of AZ any longer, he can have a friend post the bond, or a local bail bond, or even a local attorney.
I'm very sorry, but while the interlock system is not mandatory under the law, if the judge imposed it when your grandson was sentenced, as part of the penalty, then there is no way to have that requirement waived under the law. That would have had to have been done on appeal, and the ability to appeal ended 30 days after your grandson was sentenced.

I wish you the best in your future,
