I just bought a 2011 Chevy HHr aand tie TPMS seems to be off a little bit on the left front and the right back.Ive checked tire pressures with three diffrent gauges and they are right on.Ive been reading alot on the calibration process using the RKE(remote key-less entry) process but this car did not come with that option.Are there any procedures that can be done without a trip to the dealer?

I have the same issue with my 2011. I have a quality professional tire gauge and check mine regularly. One good tip that fixed mine us to adjust your pressure let a couple pounds out then add back to desired level. Once that's done open your trunk, pull back floor up and remove spinner that holds spare in place. Now unhook your battery and let it reset your ecu. This stabilized my tmps and it reads fairly accurately now. i'm sure there are easier ways but this just takes a few minutes and helped mine.
