Check Out Sens-O-Lock's mail-in, Swap-out program!

The information gathered by each DM-904 ignition interlock data unit needs to be downloaded every 25-60 days, depending on your state’s ignition interlock laws. Normally this is done at the place you had your unit installed (except in New York state) at a charge of $30 plus tax. We here at the Sens-O-Lock main office are also equipped to provide this download.

Save time!

For just $15 more per download, you can have our office ship you a new data unit prior to your scheduled download time.

• Let us worry about when your next download is due.
• Avoid missing the scheduled download date.
• Eliminate the time spent driving to and from the install shop.
• Eliminate the time spent at the install shop for downloads.

We provide all shipping materials for you to return your expired equipment to us for the download.

If you want to know more or would like to sign up for this service, please let us know when you order your DM-904 interlock device.
