    waiting area. it was shaded and breezy enough on a July summer day to wait and have lunch.
    Jenny K.

    The owner was very responsive. I was able to get in right away. it took less than 30 minutes. The location is right off the freeway inside of a gas station.

    Very good price

    Fast and efficient. Walk in and only wait for 15 minutes for the whole smog check process, price is good and crystal clear. Will definitely come back.

    Nice area to sit and wait with umbrella shade to boot!

    Such a great experience here! KS Smog is tucked up in the hills of San Leandro right off I-580 -- super easy to find. I came in on a Saturday with no appointment and was in and out in about 15 minutes. The guy who helped me was really kind and professional. While waiting, I chatted with another customer who said they've been coming here for years because of the great service and prices -- totally makes sense after my visit. They even have a nice little shaded area with umbrellas where you can relax while you wait. Quick, friendly, and stress-free -- definitely my go-to spot for smog checks from now on! Big thanks to esteemed Yelp Elite Victor for the awesome recommendation!

    I'm here for a smog!

    When I drove up someone came to me quickly. I believe the owner came and spoke with me! I told him my starter is going out. So I will leave the car running. He said it would be about an hour. However, it was way faster than that! He did my car in a few seconds it seemed like! Very quickly! Price for smog very reasonable! $45 say what! So cheap! I will be back geez next year! lol I missed a year car wasn't working. Micheal and team are phenomenal!!!! Ni went to the dmv! I was telling people that mentioned they needed a smog. I said KS smog is the place! I gave them the address and they said they were headed over there! Micheal sending u business! BC you were so kind and polite! The sun was beautiful and the outside seating area was so very nice! Thank you for your perfect service!

    I called in the morning on Memorial Day (a freaking holiday!!!) and Michael said he was open until 4PM. I somehow lost my DMV paper, but that was no issue. I was in and out of there in under 20 min. Honestly, if I could give additional stars for being open on a holiday, I would. I really can't stress this enough: KS SMOG IS THE ONLY ESTABLISHMENT I WILL SMOG MY CARS AT. PERIOD!!!

    See all

    Some Smog places charge an extra fee for my 2007 Lexus ES, calling it a Luxury Vehicle even though it's just the same car as a Toyota Avalon. Is there a "Luxury" Fee for my car?

    We do not charge extra for “luxury”.

He told us the approximate time the car would be finished and we picked it up and went on our way. The cost is reasonable for the test and the certificate. The place has some parking spaces and outdoor chairs to sit in while you wait.

    I had an excellent experience at Pro Smog with Dan. You can immediately tell Dan is a true car guy…read morewho genuinely cares about the vehicles he works on. He treats customers' cars like they're his own, and that level of care and attention is hard to find these days. His shop is always busy, but now I understand why -- customers keep coming back. You see a steady flow of returning customers and it's clear he has built his business on trust, honesty, and word of mouth. In fact, that's exactly how I found out about Dan's shop -- everyone in town seems to know about him and recommends him. Even though he was helping other customers, he acknowledged me right away and was very professional, friendly, and honest about the wait time. No surprises, no runaround -- just straightforward, honest service. The process was quick, smooth, and very reasonably priced. Excellent prices, great service, and a very honest owner. Dan is approachable, professional, and clearly takes pride in his work and his business. It's rare to find someone who is this honest, efficient, and friendly all at the same time. I highly recommend Pro Smog. There's a reason this place is always busy -- good, honest service and happy returning customers. I will definitely be coming back.

    I needed to renew my DMV registration and was required to take my Nissan to a STAR-certified smog…read morestation. I found K1 Smog through Yelp and was very happy to see that they offered a Yelp discount, which I really appreciated. As soon as I arrived, I asked Mr. Doug, the manager, how long I would have to wait for my turn. He told me only about five minutes and that the entire process would take approximately ten minutes. He was right! In less than five minutes, it was already my turn. Mr. Daniel was the service technician who inspected my car, and I had a wonderful experience with him. I asked him quite a few questions, and he graciously took the time to answer all of them. He was professional, knowledgeable, patient, and thorough in doing the inspection. Thank GOD, my Nissan passed the smog inspection! What impressed me even more was that Mr. Daniel went beyond what I had come there for. He checked the air pressure in my tires and noticed that some of them needed more air, so he took the time to add air to them. He certainly did not have to do that, and I really appreciated the extra care. I also had questions about something I had previously been told regarding my check-engine light, and Mr. Doug took the time to explain it to me in a way that helped me better understand what was going on with my car. It is always nice to come across people who take the time to be helpful and kind while doing their job well. I left K1 Smog very pleased with my experience and will gladly return when it is time for my next smog inspection.

    One of the only places I know of in the Hayward area that smogs cars 1995 and older…read more The smog equipment for 1999 and older requires a roller. For 1995 and older you need evap equipment... this is the only place I checked that had both. It is next to a tire shop and there are some food places neighboring - that is great for waiting and convenience. They two guys working here are very pleasant and love cars. I like that. I had a new cat put in and my truck passed with almost all zeros. If your cat is old keep it hot. Let it idle before you get it tested. Take it on the highway for 20 minutes before you come.
