excellent professional service Tawana provided me excellent service and valuable information and she is a very friendly and superb agent. Thank you for helping me gain the knowledge I need to make important decisions to move forward with automobile purchase and interlock contract. I appreciate Tawana's professionalism, thank you kindly!!!

I would recommend Guardian interlock… I would recommend Guardian interlock based on my initial customer service experience. Tawana went above and beyond with helping me by answering all of my questions and concerns regarding payments, fees, installation etc.. I’m new to this situation and requirement of the state but Tawana (with ease) set up my account and booked installation on two separate vehicles on the date that worked best for me. She was a pleasure to have been helped by and I hope my experience with this company continues to be seamless as well. Thanks Tawna!

Tawana was amazing really helpful made… Tawana was amazing really helpful made the process easy

Very disorganized process Very disorganized process, appointment not seen at shop, shop opened late after appointment. Equipment not received. Made to feel like lower than life for having to get one installed by staff and guardian rep not very clear on set up appointment. As soon as installed had to go right back to have recalibrated.

Great customer service! I’ve been a client at the Longmont location for some time now. Jen Ward provides the best customer service, she is always friendly and relatable. She has always been great at answering my questions and giving me the right resources!
