Here is what you need to switch from winter to summer tires and back again without paying the dealer to input the codes/serial numbers for the TPMS sensors (more than once...)
ATEQ TPMS Quicket Device | Revolution Supply Co.
I do admit that the cost of this is ~ the cost of paying the dealer twice to have the codes read/inputed into the Insight's computer and would only be cost effective if you are swapping tire sets. I have two Hondas that I will be swapping tire sets on so it quickly pays for itself for me.
The Insight's computer only holds 4 codes so the Quickset holds upto four vehicles with 2 sets of tires (or 1 vehicle with 8 sets!

)
The Tire Rack USED to sell this device online but when it became hard to get they stopped offering it. I haven't check the Tire Rack site for it lately so YMMV. It took me over a month for the above company to get stock in when I tried to order one through the three companies that had web sites offering them for sale... All three were out of stock at the time I was trying to get one.
IF the Tire Rack will tell you the codes for the new sensors (I have read they will and won't tell you the codes

) then all you would need to do is use this device to load the codes into the Insight's computer. If they will not tell you the codes (serial numbers, whatever...) then a trip to the dealer or someone who can reset you computer is needed.
I have one of these Quicksets and two sets of stock wheels with stock TPMS sensors. I have one set of winter tires and one summer tires. This past weekend I removed the winter tires, installed the summer tires and then used the Quickset to input the summer tire sensor codes into my Insight's computer and then drove ~ 1/4 mile @ less than 20 mph to have my warning light go out. BTW, I was in my housing area with a posted speed of 20 MPH and didn't get off my local street before the light went out. I was kind of surprised and happy that it worked as well as it did!
Be advised that you can read whatever codes are stored currently in your Insight's computer for the TPMS sensors with this device.
My problem was I wanted to get on my winter tires NOW and I couldn't get the Quickset (backordered) so I went to the dealer and paid the $$$ to have them read the codes off the old and new wheel sensors. I asked for the codes and they supplied both sets! Once I got the Quickset, I connected it to my Insight and verified the codes that the dealer gave me.
If you can get a Quickset BEFORE you unmount your current wheels you can read the wheel sensor codes first and then go to the dealer with the new (to you) wheels/sensors and pay the dealer $$$ to read the sensor codes and input them into the computer. Once you get home, you can then use the Quickset to read the new codes and save them both and then you can swap tire sets whenever!
