I am sure that he will go "above and beyond" for you, as stated numerous times in my phone calls with him. After a week of assuring me that he had the interlock device, and day after day of excuses as to why he doesn't actually have any in stock, we finally made an appointment where he said "he/they" would be there. 10am arrives and we show up to get the device installed. CHARLES is no longer operating out of this location. So then we go to the other location as advised by the people in the shop next to his. Now at the new location, and the new people say he moved from there too. After several missed calls/texts/ and voicemails, Charles answers the phone hungover and drunk at 10:20am telling me that he just needs to shower and then he will be there. ARE YOU SERIOUS. ARE YOU MENTAL??? Who operates a business like this!? This should be all you need to know about how fun it is to deal with Charles and this "company". IF YOU SEE THE NUMBER 916-275-2292, or the name CHARLES, attached to any interlock service, just know that he's a total waste of time, and if the companies name is different than "California Ignition Interlock" it's because he constantly has to change locations and business names to avoid his awful reputation. Thanks for the huge waste of time!

Don't judge me! It's all over with now thanks to the staff at Cii and Charles the owner. They made…read moreme feel less like a degenerate and more like a human. Overall price wise and service can not be matched, albeit I hope those of you out there never need it. In my humble opinion Charles and his team made the experience as best as it could be. Not that this guy will be visiting this place again, ever. Best of luck!

Norcal Interlock has made this part of my process so easy! I read so many reviews and heard all the…read morehorror stories about people using other companies for IID's, I was scared to even get one put in my car. Then I found Norcal Interlock and their reviews were actually outstanding. I called up and Henry answered and walked me through the whole process. They stayed and continue to stay in direct contact with me about everything, via text, as I preferred. I've been using them for quite a few months now and have NEVER had any issues with the device. They are fast to schedule me and get me in and out very quickly too. They always have such pleasant attitudes when I come in. They have made this process so easy and painless. Definitely don't fall for those main brand companies even if it "sounds" like they are going to give you a "better deal". I was almost drwn to another company because the price was a little cheaper... glad I read theirr reviews first. Norcals pricing is super affordable too. I would suggest Norcal Interlock to anyone and everyone that needs to have one of these things installed.
