I have ordered these and have them installed. None of the scanners are detecting them after the installation. Going back and fourth with Amazon and the seller was waste of time as no resolution or exchange can be provided.

These installed well on my 2012 Lexus IS 250. When logging the new sensors with the 2025 Launch Creader Elite, I ran into a trouble code on the Creader Elite. It said “ID registration failed due to a communication error with the ECU while in initialization mode. Terminate initialization by connecting TC and CG of the DLC3 for 30 seconds.” I had to contact AI for an interpretation and it told me "The TPMS ECU got stuck in initialization mode and isn’t responding properly. To reset it, you need to manually short two diagnostic pins — TC and CG — in the DLC3 connector (your OBDII port)." Here are the instructions: How to Terminate Initialization (Safely) 1. Locate the DLC3 Connector • It’s the same OBDII port under the dash where you plug in the Creader Elite. 2. Identify Pins TC and CG • Pin 4 = CG (Chassis Ground) • Pin 13 = TC (Test Connector) • These are numbered from left to right, top to bottom. • You may need a pinout diagram or flashlight to confirm. 3. Create a Jumper • Use a paperclip or jumper wire to connect Pin 4 to Pin 13. • Leave it connected for 30 seconds with ignition ON (engine off). 4. Remove Jumper and Retry • Disconnect the jumper. • Reconnect the Creader Elite. • Retry the TPMS ID registration process. Why This Happens • The TPMS ECU sometimes locks up during ID registration, especially with aftermarket tools. • Shorting TC and CG forces the ECU to exit initialization mode — it’s a safe, Toyota-approved reset method. I had to do the above "shorting method" twice, which was a chore for this fat boy to get down in the floor board to access the OBD2, and then plug the 4 new ID numbers into the Launch Creader Elite twice, but it all worked out. I hope all this helps someone else who has the same problem. Still a lot cheaper than paying garage over $500.00! Now lets pray the Marsflex batteries last at least 4 Years, if not, go with Denso. More expensive, but proven to last.

I had these installed on a 2008 Lexus RX350. They work great, without any programming issue.
