Have been unable to use my vehicle for…
Have been unable to use my vehicle for almost two weeks. After a total of 6 hours on hold last week, agent stated they would send replacement device to service center overnight. Two days later no replacement, spent another two hours on hold just to be informed first agent had done NOTHING but document my issue. Second agent stated that replacement would be shipped overnighted to service center but as it was late on Thursday new device would not arrive until following Monday.
Monday arrives, defective device allows me to start car after 20 minutes of 'Blow Longer" messages and multiple restarts. On way to service center rolling test was required 200 yards from service center which reported "FAIL" status.
Tech replaced device, 'NEW' device requested repeat samples due to "BLOW LONGER, BLOW HARDER" requirements, reset buttons did not work.
Tech tried troubleshooting and had me repeatedly blow into 'NEW' device which resulted in various timeout errors and three different BAC readings, which were impossible as I had started my vehicle with no BAC issues and a passing sample to get to the service center.
Tech tried her best but device locked up for 30 minutes, stated she would email company. I also tried to phone company again over the next FOUR days and never got anyone to pick up phone. I went on website and filed EMERGENCY support request, no response as of yet. I have now been without use of my vehicle for a total of 8 days, with only limited access due to device issues for 5 more days.
My IIR restriction ends in three days and it seems like I will have major issues contacting this company to get the device removed, resulting in continued billing.
Anyone having problems with Lowcost Interlock should consider getting together for a class action suit against the company for its support and billing practices.
Your products are trash
Your products are trash. Constantly having to tow my car for inspections just to get my car “repaired” and than turn around and do over and over again every 4-6 months.
Contractor had no idea I was coming
Contractor had no idea I was coming, parts were not there. They just scheduled appointment anyways. Contractor took all day when they said 1.5 hours. What a joke.

I the lady I talked with on the was patient, kind and friendly. She answere all my questions.
Easy to use, installation sucked
Great service over the phone and very easy to use device.
Appointment was scheduled for 12 pm and I was on time however the person who does the installation, left to get a part just before I got there. I can’t miss appointments in my job not sure why it’s ok there for them. I was also told that my install would take 2-2.5 hours, I left the car at 12:30 and it wasn’t ready until 5:30 pm again not very professional to take a full 3 hours longer than the quoted time.
Monthly cost and installation cost very…

Great Interaction

Great service and explaining
AVOID this company!
No stars they are the worst and so is their equipment. Customer Service is a joke more like Customer Torture. They will cut you off if you ask to talk to a manager then make it hard to get a hold of anyone after they hang up. The equipment will suck the battery down every other day if you do not drive every day. had to have equipment replaced. They do not talk to their vendors any different then the customers. AVOID this company.
Highly recommend
Extremely helpful for my first experience with IID. Answered all my questions appropriately. Had an amazing attitude, friendly and respectful. I would highly recommend.
Registration was easy and affordable
Polite and knowledgeable representative guided me expertly through the registration process and answered all of my questions in a thorough and quick manner.

McKenzie was very respectful and very kind. Took her time to explain everything to me and definitely would recommend this company to everyone now.
customer service still matters, and wins biz!
Yesena was so pleasant and thorough, and has great customer service... which made me choose to pay a bit more to become LowCost Interlock's customer over another company I both researched and contacted.
The same can be said for the company Yesena connected me with, Norcal Interlock. Henry has so far impressed me, as well, and also speaks highly of being associated with Low Cost Interlock.
I don't have any intention of failing any tests, so fingers crossed, the equipment will be stellar, too.
Excellent Customer Service!
Excellent Customer Service!
The individual who assisted me answered all my questions and concerns. She even called the installer to verify some answers to some out of the norm questions I had. Payment, service set up and installation was easy! I'm very happy.
TERRIBLE EXPERIENCE
If I can provide zero stars I would. Customer service is a nightmare! Specifically Amy & Sabrina in technical support/customer service, while explaining my experience with the breathalyzer device Amy decides to shut me up and instructs me to listen then goes on to say that I have a fume that is causing the fail problem I’m attempting to explain I do not have anything that is scented in my vehicle at this time she decides to places me on hold for no apparent reason gets back on the line and asks is there anything else I can assist you with I ask to speak with a supervisor she said that no supervisor is available (by the way what company gives every single supervisor the day off) I ask for a supervisor’s contact info she refuses to provide the information then suggests that customer service can assist with the information I get transferred to Sabrina explain to her what just happened she places me on hold saying she’ll be back with the info while on hold she transferred me back to Amy, Amy transfers me back to customer service I punched in my cell number for a call back I immediately get a call back say hello several times obviously someone was on the other line because I was then transferred back to Amy at this point I’m express my frustration with the company then she accuses me of arguing with her when I am simply expressing my frustration. I wasn’t able to receive a resolution other than place the device in front of a fan (when there aren’t any fumes in my vehicle that would trigger the device to begin with) I was not offered any troubleshooting which is terrible! Now I have to wait until tomorrow to speak with someone that can hopefully assist in the meantime my car is sitting there inaccessible. Oh not to mention Amy said that if the fan doesn’t work that I’ll have to wait for a replacement to arrive which can take days to arrive!
