My fans that cool the engine do not come on at all. The temperature climbs when I sit still. When I drive, the car seems to cool down.What do I need to do.

Bank 1 is the rear O2 sensor, but experience says to change both. The front one is right behind the engine in the middle of the engine compartment. The rear O2 sensor is on the top of the exhaust pipe, just behind the catalytic converter. But the same code that shows it is the O2 sensor (which is P0420), is the same code for the catalytic converter, or a vacuum leak. Make sure if you do change the catalytic converter, ensure that the new one is OBD-2 compliant. And the vacuum leak could possibly come from the manifold gasket. Let me know what the problem was!

The battery is under the hood, just behind the passenger headlight.
There is a black bar that crosses over the battery and goes back towards strut tower. Remove this bar and the three bolts; probably a 12 or 13mm socket.
Remove the negative (black) battery cable with an 8mm socket or wrench. A 5/16" should work also.
Then remove the positive (red) cable with same socket.
Remove the battery clamp and bolt. Probably a 12mm socket with extension.
It's tight, but the battery can be removed.
Reverse instructions for installing the battery. (That includes hooking up the red battery cable first, then the black cable.)

That indicates there is a pass-code error. There are a few reasons why. Easiest way to explain it, is that your key has a "chip" in it, with a resistance or "password" that your cars computer is looking for. It means that your cars computer did not see the right password. It will probably reset itself once it sees the correct password a few times. If not, you want to get it checked, because if it happens too often, the vehicle will not start.
The causes for this problem on these vehicles are generally the ignition switch or passlock sensor. There is also sometimes a water leak that occurs at the right front cowl, check the inside passenger side floor area, if it is wet. It could then be a BCM problem. Goodluck
