Battery Related FAQs


What are mistakes made when jumping a car?

Mixing up negative and positive cables is the most common mistake. When you mix up the negative and positive cable it ruins your car's alternator. Just remember black to negative and red to positive. Other common mistakes are using cheap cables that don't conduct properly, letting the cables swing and become detached, touching the clips together, and ignoring cracks in your battery or dirty battery terminals.

What should I be careful of when changing a car battery?

It may sound obvious but be sure that you do not drop the battery. Be careful not to let the tools touch both the negative and positive terminals simultaneously, as it could create a spark, cause the battery to short out, or even damage the vehicle's electrical components. Make sure to separate the cables to the side so that they don't touch the battery until it is in place. Attach the negative cable first and then the positive cable. If have any doubts while you are trying to change your battery you should always call in an expert.

Car Starting Related FAQs


How do I unlock my steering wheel?

Place your foot on the brake and turn the wheel in the direction in which it has a little range of motion. This should ease the tension in the steering column and allow you to turn the key. Turning the key unlocks the steering wheel. Do not try to unlock your steering wheel without a key or if the battery is dead. This should only be done by a professional auto repair technician.

How do I change my keyless entry remote battery?

This should work for most remotes:

  1. Remove the metal blade key from the remote.
  2. Use a standard (flat head) screwdriver to gently pry open the fob
  3. Remove the battery. It is usually a small round lithium watch battery.
  4. Insert a new battery
  5. Snap the key fob back together
  6. Insert the metal blade key into the fob.

If I could give them 10 stars I would! We had our check engine light on and were prepared for a $1,500 bill. They called back and a wire was not plugged in correctly so they only charged us for the diagnostic plus $45. What a relief! An HONEST mechanic. We are customers for life. And they gave my 2 year old and 5 year old sons brand new Hot Wheels in the package to play with.

Where do I start ADAM ADAM ADAM remember that name his customer service was outstanding, spectacular, and above and beyond, when I first pulled up he had a Genuine spirit, His presence made me feel very comfortable, I didn’t get this feeling “this guys just here to do a job and get paid” but that he has a heart to care about his clients, He listened, took notes, and understood what I was requesting fully. I told him how I went to another mechanic shop and how I was treated there and how much they were trying to charge me to fix an issue he emphasized with me and understood that not everyone have money to blow especially fixing unnecessary things that doesn’t necessarily pertain to the issue at hand I was being upsold at another mechanic shop and over charged but ADAM rest assured he doesn’t do that there he knows when you treat a customer right they’ll continue to be loyal. I was expecting to have it in the shop for a while and having to Uber to work and back it gets expensive when you’re 30 mins away from work. He was able to fix my Auto Stop Start and Check Engine light for dang near HALF the price of another mechanic shop quoted me and didn’t upsell me and fixed it in 2 DAYS! He was so nice I offered a tip 3 times and he denied it real genuine he also checked in on me to make sure things were straight. I was extremely happy to know it’s fixed and that I’m saving HALF the price I was quoted I found my Guy and Mechanic shop at Dennis Auto Motive HIGHLY RECOMMEND quotes-image

I’ve trusted Dennis Road Automotive for many years, though it’s been a while since my last visit, mainly because they’re not open on weekends. I’ve always appreciated their straightforward service, and I still miss Riley, who brought a great personal touch to the experience. On my most recent visit, I was charged $374 for a new battery for a Lexus ES350. I’m not sure how that compares in today’s economy, but it gave me the same feeling you get when dining out these days, quality isn’t necessarily better, yet the prices seem to jump significantly. The work was completed, and the team was professional, but the cost left me wondering if the value aligns with what it used to be. I still want to support businesses that have served the community for so long, and I hope they continue to provide honest, dependable service at a price that feels fair in the current market.quotes-image
