Who replaced them and did they reprogram the ECU?

I went to mechanic tyre shop and got all 4 sensors replaced. They programmed the sensors using their tool and put all sensor ID but c2126 still on

If you have a button for the main/2nd tpms sensors make sure that is in the correct position. If that’s ok have them program the ids into the ECU again. DO NOT TURN the car off and have them rescan each sensor again in this order Left front, right front, right rear and left rear.

So basically after installing new sensors, I registered through techstream using tpms module. I put it on main and re registered all id's. I tried deleting dtc too but it came up as soon as I deleted them.

It’s common for the light to come on after entering in the Id’s. Don’t turn the car off and go for a drive. The ECU is waiting for the sensors to send out a signal. Once the ECU receives the signal the light should turn off.

Sensors need to be triggered for them to be active.
