Mike at KS Smog was fantastic! Friendly, professional, and had me in and out in about 15 minutes…read more The process was quick and easy with no hassle at all. One thing I noticed--when I arrived right at 8:00 AM, there were already five people behind me waiting for smog inspections, so definitely come early! It's easy to see why they're so busy. I highly recommend KS Smog if you need a fast and efficient smog check. They open at 8:00 AM, which is earlier than many other smog shops in the area that don't open until 9:00 or 10:00. If you're looking for a convenient place to get your smog done before work or other errands, this is the place to go. Highly recommended! Fair price for smog too!!

Fernando, the owner, is a great guy! I've been coming here for about five years, maybe more…read more Fernando is friendly, knowledgeable, and friendly. Did I say friendly? He gets you in and out quickly, even while being friendly and conversational. It's a test only center so you can be sure he's not going to try and get you to perform unnecessary repairs. My son and I were doing some repairs on one of our vehicles, which required the battery to be disconnected. This reset the emissions readiness of the vehicle, and the onboard computer needed to evaluate the vehicle under certain driving conditions. Fernando explained what needed to be done, and my son completed the hoops and we got back in for the smog check. I definitely recommend this place!

I stopped by on a weekday morning, and asked how long it would be for a smog…read more Fifteen minutes. How great. Amaru was working on one car ahead of me. When it was my turn, he quickly got my info, and key and took care of the testing. He was quick and efficient. I had no issues. The price was reasonable, I expected it to be more actually. So that was a nice surprise. Amaru was pleasant. And I would definitely recommend this business.

I came here for a retest after my car failed the first inspection. I paid $59 without realizing…read morethere was a $39 offer on the website. When I politely asked about it during my return visit, the employee (different from the first time) was immediately rude. I was trying to explain myself calmly and even said "let me explain better" since English is not my first language. Instead of helping, he gave a very hard, mocking laugh, acted like he couldn't understand me, and then started yelling. It felt disrespectful and humiliating. I was calm and respectful the entire time, so the reaction felt completely unnecessary. I also saw other reviews mentioning rude behavior from staff, and others saying they were refused the $39 discount advertised online. At first I ignored those reviews, but now I understand what people meant. Overall, the experience felt unprofessional, and basic customer respect was missing.

Great service! I needed a lot done to the car. All the brakes and rotors were changed, oil was…read morechanged, and also the headlights weren't working. The headlights took an extra day since the car is a euro and the parts needed to be ordered. The place is busy and full of cars! Definitely go in early or call to see when the best time is to get your service done. I was looking at the low star reviews.... Be realistic with your expectations when bringing in your car. If you have a unique problem, chances are it's going to take longer than you would want it to take to get it fixed. Otherwise just go to the dealer to get it fixed and pay dealer rates/prices. All in all, Vinh's pretty straightforward and honest about the labor and parts. Definitely recommending the shop to all my friends!

I was going to drive my car a very far distance and needed to get my tail lights fixed asap. Luckily this was a local San Leandro San Lorenzo area option and Mr. Lei was able to assess my car and return it the next day. something was wrong with the circuit boards so he was able to get me light replacements & even helped me with another issue on the car door. Even though I know very little about cars, Mr. Lei explained everything in a way that was easy to understand. Will come back for our annual oil change, this was a great value, experience, & overall great service.

The owner is always welcoming and takes the time to explain what my car needs without any pressure or upselling. With many years of experience, their knowledge and expertise really show.

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.

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 dropped in last time for my smog check and they were able to take me without an appointment. Took about 10-15 mins and was reasonably priced.

The catalytic converter that was installed carried a c.a.r.b. executive order number that was appropriate for her vehicle. She also provided documents supporting the legality. I get it though, and old lady easy to fail and not explain anything because you yourself do not understand the smog laws. Long story short it went to the state ref. The state ref was confused on why it didn't pass. He urged my mom to go back but she didn't and I'm glad. No value here folks especially if you're a female, they'll just rob you. Not sure if the techs are the same or have been but they're idiots.

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.
