The other, I had my trunk release repaired by my mechanic, and after that the trunk button on the remotes stopped working, so I go see him and explained what I had done to the trunk. He said let me see the remotes, and went out to my car. He found out that my mechanics didn't connect all the wires. Now he could have told me to go back to my mechanic, but he didn't, he fixed it and sent me on my way!

All of the reviews are true!…read more I recently got a tint job and remote car starter for my Honda Accord, and after doing research around this area, this was the only place I even considered going. Mike and his team do THE best work at reasonable prices. The quality is worth every penny. They were highly responsive and communicative, and were able to get me in the shop fairly quickly. They offer a variety of remote car starters based on your needs and budget, and they take the time to talk you through the options they offer, ask questions about your needs and wants to help them understand what to recommend, and answer any remaining questions you have. I have seen their thorough and STELLAR work on interior lighting, audio/bluetooth systems, and high quality window tinting. I look forward to working with them for future upgrades to my car. I'll certainly be returning!! Go here! You won't regret it.

Trevor and everyone here is awesome the quality of work is impeccable and he always says if you have any issues at all just give us a call and we will do the best we can to resolve it and let me tell you he has never let me down which allows me to feel confident in any work I have done here, heck I literally dropped one of my car off last night and he's adding a remote start for me today. Also they do a lot of different things my mechanic sent me over here when I was having a wiring issue with a headlight in an 05 Focus and they were able to figure it out and have me on my way, also I owned a jeep iykyk the wiring in my jeep door something was off with it idk what it was fully but when I had picked my car up everything was back to working normally and even better than before. The prices here are very good here and fair, even if I could find it cheaper elsewhere I would never recommend doing that because for professional quality and service you need the right place, people, and price and this is just that! I have trusted Cartune's to work on my cars since I was 16 years old (over a decade) and my whole family has since used this company. I drive 30 minutes to drop my car off here and I live in a city and this drive is a few towns over so I have options and will always choose here over all those other options available. Thank you for all the time and effort you guys are always making to keep the customer confident and satisfied with their purchases and never having people feel pressured at all, they will always say don't be afraid to ask questions which I ask a lot of! 10/10 would recommend with confidence!
