Reset security on 04 monte carlo
If you leave your key in the ON position for 15 minutes, the security system should relearn it and work once again. But the halo around the lock cylinder needs changing. You can purchase a kit from GM that includes the lock cylinder along with the halo. you do not need to replace everything, just the halo is what usually goes bad.
How to change spark plugs in a 2004 Chevrolet Monte Carlo SS, V-6
The three plugs in the back are a bit tricky but 2,4,6 are all back there 6 is right by the O2 sensor you might have to feel around for them but you don't need a jack or any special tools just a ratchet, small extension 5/8 SP socket slide the metal sleeve forward and yank ******* the rubber plug wires after a while they will come loose 4 it about 3 inches to the left of 6 and 2 is back behind the coolant Reservoir
Oxygen sensor readings go to 0 at wide open throttle
I suspect your catalytic converters are the culprit. Once they become clogged, they will rob your engine of power and provide false readings to the O2 sensors.
I would also check the compression on all cylinders to ensure you do not have any valves burnt or not seating completely.
Finally, these aluminum engines are notorious for blowing head gaskets, although I am still leaning towards the catalytic converters. FYI - there should be O2 sensors pre and post cat, which should help with troubleshooting.
I hope this helps.

2004 monte carlo problem with key
This is a mechanical issue. Try moving the gear shift around. There's an interlock that prevents you from turning the key all the way off if the vehicle is in gear. This is so that if you are driving and the key gets turned accidentally, that the steering wheel does not lock! It the linkage is messed up, or in the case of a console shift, the cable is damaged or out of adjustment, you cannot turn the key to off. Sometimes you can push the shifter harder into park and it will allow the key to be turned the rest of the way to off, whick will also verify this problem.
