Took a bit to coordinate my scanner to program but YouTube videos and perseverance paid off. Vast savings over estimates given to have a shop replace them. I used a bead buster to gain access to my old tpms, install these, air up the tire, then reprogram sensors to my 08 HHR.

Working perfectly. No need programing. I just used inbuilt learn on car. Press lock and unlock button of remote to start learn. Good purchase

At first I was worried as these sensors were a different shape than the sensors I removed from my 2016 Chevrolet Equinox LTZ. However, I installed them anyways and hoped for the best. Thankfully, once installed, they activated and paired with my vehicle perfectly. I used the Aicel EL-50448 TPMS tool to activate the sensors. I'm extremely happy now that I no longer have to clear the TPMS warning every time I drive.

Bought them a few months ago and installed 1 in my 2017 equinox, installed fine and programmed fine. Another sensor went out, so I installed another one and that one installed and programmed fine also. So far 2 for 2 on installation and working fine.
