Works great and easy to use. The bad... No instructions (4 out of 5 stars). Just do a search on the internet and YouTube to find out how to use this device.FYI... When using the device be sure you touch close to the rim were the valve stem is and the tip is on the tire for this to work as pictured. I have tried putting the tip of the device on the rim close to the valve stem and it would not work. This was used on a 2014 Chevy Cruze ### ⭐⭐⭐⭐⭐ The tool you need *by M***E on February 8, 2019* I have a GM car (2016 Chevrolet Cruze LT). When the back right tire went to 27 pounds of pressure the warning light came on and I got a warning to increase pressure in that tire. I did. That is when I discover in the owner's manual, the warning light will stay on and I will get a warning every time I start the car until the system has been reset. REGARDLESS if the pressure has been corrected.I can take it to the dealer and be charged for it, or get the tool. I got this tool and followed the instructions in the owner's manual. It took less than 4 minutes. You need a 9 volt battery to get the tool to work. The tool has one button. Once you start the car's relearn sequence you hold the tool against the rubber of the tire near the valve and press the button on the tool. ### ⭐⭐⭐⭐⭐ works for 2013 GMC Acadia *by A***8 on August 7, 2018* This relearning tool apparently draws power right at the limit of what a 9v battery can deliver. I started with a fresh 9v and could only get the first 2 wheels done. I tried another fresh 9v and still could not get past the first 2 wheels. (If you don't complete all 4 in one session, the data is rejected and you have to start over.) Finally, I doubled up the batteries in parallel, and that did the trick. The tool seems to work best when the antenna is pointed perpendicular to the sidewall near the base of the valve stem. BTW, for the 2013 GMC Acadia, initiate the process by turning the key to the "on" position (not just "accessories"), then hold down both the lock and unlock buttons on the key fob until the horn beeps twice. Each corner light goes on in sequence to show you which wheel to set. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/58792735-szark-el-50448-auto-tire-pressure-monitor-315-433-mhz](https://www.desertcart.sn/products/58792735-szark-el-50448-auto-tire-pressure-monitor-315-433-mhz) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-09-23*
