Precision Sound & Security — Local services in Chino Hills

Terrible! We called twice to get a price on how much it would be to get a complete alarm with remote start, and window relay installed, both times they gave us the same reasonable price but once we got there they added an extra 200. The employee said that both of the people were misinformed about the pricing, so we reluctantly agreed to still get the alarm installed. When we went to go get the car later that day they told us that it that everything was all set and ready to go. When we got home we noticed that neither the trunk release nor the window relay was working. So we called and they told us that it would be extra to have those two things done even though they had said that it would be done with the price that they had given us. We were very upset, but they had just closed so we couldn't go back and fight it. After a week of trying to get the car back in, we finally got an appointment. They informed us that they would need to charge us for the window relay and again reluctantly we agreed. Then that evening when we picked up the car they charged us 147 dollars for just adding the trunk release even though that was supposed to be included in the first price. So we either had to pay for it or they would keep the car until Monday (It was Saturday). So we paid and when we got home the trunk still wasn't working! This was honestly the worst experience I have ever had...

I have been using Precision Sound for about 15yrs now. Darryl and Colin and team are specialists when it comes to anything about your car. I have a passion for cars and they are the best of the best. When I bought my 2012 Dodge Challenger RT Bright White. I had them install Halo lights, Borla Exhaust, Sequential back lights, FOOSE Chrome Rims, Throttle Body, Focal Speakers and a K & N Cool Air Intake and also tinted my windows. I now have a 2019 Dodge Charger Go Mango color which I had them install Foose Black Rims, Black Wrap for my hood, Black spoiler on the back, and some racing decals and also tinted my windows. This car looks bad a$$ and looks like its going 110 miles an hour just in the sitting position. I highly recommend this group they are honest, genuine, and hard working, and they use their expertise to the fullest. I will continue to use them as long as I'm buying cars and wanting custom jobs added to it or for any other reason they know what their doing and take the time with you...

I was on my lunch and needed some assistance with my car's headlights. It's supposed to be an "easy" job, but that's a relative term. I explained my needs to Daryl and rather than spend any time taking my name and trying to fit me into their schedule, he grabbed any necessary tools and got things done for me in minutes and with plenty of spare time to still grab a bite. I was so pleased with his service in getting this taken care of, that I paid him more than he asked, which I've never done before. I grabbed a couple business cards and will pass them along to others....
