The Tire Pressure warning light was blinking on this vehicle, and I customize it with these: - C2122 and C2124=transmitter id not receive(main) so how do I locate these sensors and I replace and register them; I attached the screenshot below.

Note:-(How do retrieve ID5 registration code)

The ID5 sensor registration is for the spare tire does the car have one? Also here is how to replace and register the tire pressure sensors, apparently there is a small battery that goes dead which needs replacement. The tire bead will need to be broken, which is typically done at a tire store. It does not tell use which tire is ID2 and ID4 but I can assume it is the front and rear passenger side tires. Check out the images (below). Please upload pictures or videos in your response to the problem so we can see what's going on.

I have identified the ID location by loosening the tire and removing the sensor and checking them by looking at their IDs. ID2 is the left rear tire driver side and ID4 is the left front. So, I have changed sensor and registered it, it began to see tire inflation pressure for the 2 sensors but the light remains and with fault code: C2126, and there was no ID code for spare tire, so how do I retrieve the I'd code?

Here is the information I found on the code:

The fault code C2126 on your 2011 Toyota Corolla indicates a problem with the Tire Pressure Monitoring System (TPMS), specifically "Transmitter ID not Received in Main Mode." This code suggests that after all IDs are registered, the Tire Pressure Warning ECU and Receiver do not receive radio waves from the transmitters whose IDs are stored in the ECU.

So, it sounds like one or more of the sensors are not working.
