Lifeloc has highly trained technicians who can help diagnose and fix problems over the phone in many instances. If however, your breath tester needs to be sent in for repair, we provide the best customer service available.

Returns for Repair or Service
To help us maintain our quick response time we ask that customers with equipment that need service or repair call us for a Return Authorization Number (RA number) before sending the unit to us. The procedure is the same for warranty or non-warranty work, as follows:


1) Call 800-722-4872 for an RA number. Supply pertinent information including the reason for the return, the serial number of the unit, your company address, phone number, a contact name, and purchase order number if required.

2) When the Lifeloc technician gives you an RA number you may then ship your unit back to us. Please package your unit carefully to ensure it is not damaged in transit, as Lifeloc is not responsible for damage that occurs in the shipping process. You may want to purchase insurance from your shipping company to cover the cost of the unit in the event it is damaged in shipment.

3) Make certain that you write the RA number on the outside of the box and send the package to:

Lifeloc Technologies, Inc.
12441 W. 49th Ave. Unit 4
Wheat Ridge, CO 80033

IMPORTANT! Lifeloc will not accept packages sent to us freight collect or "billed to recipient".

When we receive your unit it will undergo a full factory diagnostic check. If it is in need of any additional repairs you will be called with an estimate. Our typical repair time is 3 to 4 days and we send your instruments back via 3-day air freight.
