“This place had the battery and the information from JUN was useful. The whole interstate team was actually very helpful, I called around to find a top tier battery to a few different interstate battery locations and they actually gave me honest feedback and ultimately gave me a better understanding of the battery that was still going to be sufficient and reliable for my purposes. Between that store and this store , everyone was helpful and kind!”
“Very great service. I called before I came asking them if they had the brake parts in stock for my car and they did thankfully . They also recommended me an auto shop to change out my brakes and I’m very grateful for that .
Thank you so much!”
“Brian and Giacarlo provided exceptional service! Got us the battery and loaned tools we needed to replace a key FOB battery as well as test our battery. Great, quick service and couldn't be happier!”
“Went in looking for a new battery, the staff was extremely helpful and polite. They informed me that I did not need a new battery, and the issue was some loose cables. I appreciate their honesty and will recommend them to everyone that I know!”
“Great service and extremely convenient. I was able to get my car battery replaced on an hour's notice (probably less actually), in less than 15 minutes. And the price was reasonable. I highly recommend!”
“Honestly, the best experience I’ve had at any auto parts store the staff (Sam and Bodie) are very knowledgeable especially about Subarus and went the extra mile for me. Would definitely recommend this location”
“Freezing weather and no one anywhere else could replace front bulb for my jeep grand Cherokee without going to a dealership and paying $170. Dane went above and beyond to go outside in the freezing weather and change it. Kind and professional. I am truly grateful and this is why I continue to only go to O’Reilly not the new big Auto Zone next door. Employees like this are hard to find, promote him.”
“I didn't shop here, or buy batteries. But I did pull into their parking lot to start cleaning up my 6 year old who vomitted in the car in the middle of highway 36 as it's right off the exit. One of the staff members there came out and offered us to come in through the back door and use their restroom to get cleaned up and found plastic bags for us for her clothes, etc. This was a small kindness, but meant a lot to us to help deal with a hard situation. So I don't know about their batteries, but I do know they're decent people! Thanks for help!”
“Chris was so helpful and knowledgeable and went out of his way to make sure I was safe and taken care of in my car. The staff was friendly and I will definitely be back for all my auto needs!”
“Carmen the assistant manager deserves a raise! She went above and beyond for me with helping install my passenger door mirror that was taken off unexpectedly. She was very knowledgable and made sure I was safe to get back on the road with my new mirror. I trust her and will definitely be back to see her if I need help!”
“Omar rolls up to work in a white, modded Subaru that sounds like a caffeinated chainsaw—and that alone says “manager material.” The man’s got a beard so wise, it practically scans barcodes on its own. He doesn’t find car parts—car parts find him.
Got a check engine light? Omar diagnoses it just by hearing your car pull into the lot. Ask for blinker fluid as a joke? He’ll sell you some and throw in a free air freshener that smells like shame and horsepower.
Under Omar’s reign, Westminster’s O’Reilly is going full legend mode: sales up, complaints down, and the break room stocked like a NASCAR pit crew fridge.
Omar’s not just a manager—he’s the bearded, turbocharged heart of the auto parts world.”

“I've used this location for fixing screens on our phones before but this time I reached out to them to see about getting a new key and key fob for my recently purchased care. Jon, the employee I dealt with was very informative and honest about wishing he could help but not being able to because of the year and model of my car. He said their system was not able to support the programming. I appreciated his honesty and not wanting to give it a try. He made sure I knew there would be a possibility of the key I had no longer working if we tried. It says a lot about his character. Some people don't think about the possible consequences. Thank you for your help, Jon.”

“Came in for some windshield wipers and I couldn’t figure out how to put them on. Went back and Carlos came out to help me, well I bought the wrong ones and he helped me locate the correct ones at another location (told me what ones to make sure I got as welll) while I grabbed something else in the store he went back out and put my old wipers back on for me. He was such a nice young man. As I was leaving another employee coming in for their shift held the door and wished me a nice day. Staff here is wonderful and I appreciate their customer service!

This shop is my go to for parts, supplies and proper help.”
