PSI monitor showing measurement for wrong tire

Hi, pardon my inarticulate description. I'm hoping someone can enlighten me so I understand what's going on.

The tire pressure monitor was showing that my left front tire was getting progressively low. Despite putting in air, it was only showing a PSI of 15. Went to the tire store today, and they told me that my right rear tire had a nail in it and was leaking. I reiterated what the display said, and the guy at the tire store asked if I had recently gotten my tires rotated (I haven't), and told me that the sensor was screwed up. The left front tire was overfilled (because I believe what my car was telling me and not using a gauge, dumb me) and the rear tire was very low.

In browsing the forum, it sounds like the sensor needs the individual tire, not the location, so a tire swap would result in incorrect PSI data, and therefor a reset is recommended. Then I got lost. How do I reset the PSI monitor? People talked about a kit...I don't want to buy a kit. I want to know if it's something I can do, or do I need to take it to the dealer. If there is a kind soul who could explain what's going on and how to fix it, I'd be eternally grateful.

There is full details on the TPMS system and instructions on how to reset it so that the display is correct for each tires location in the owners manual. I'm suprised the tire store didn't do it as for them it's a easy process.
