I got new TPMS sensors from TireRack... not sure what brand.. I have a feeling it's not OEM... but still, as long as they work. PLus I wanted the option to switch back to stock wheels in case I ever need to.
From what I heard so far, Touring have self learning TPMS, as does my Ridgeline RTL. I guess it was a cost issue, reserved for the higher models? Meanwhile, all EX-L, EX, and LX have to be re-sync'd. You can take it to any dealer, or tire service shop and they should have the tools to wake the sensors.
In my case, I wanted the option to re-sync them at home whenever I wanted to, so I got the ATEQ TPM Quickset Rest tool from Tire Rack. You have to link the tool to the car (OBD2 port) and your laptop. This tool lets you wake up the sensors to be sync'd. It can learn up to 4 cars only. No adding or erasing cars. This seems like a pain, but I find it more annoying having to have someone else sync them for me each time I swap. Also, it costs $125 (retail) vs. Bartec Tool's $1800 (retail)
That being said, I got it last night, but didnt have time to even open it up. I also received the H&R Springs too, and my plans are to install the suspension this Sunday. Get alignment Monday, and also sync the TPMS sensors then too.
