KEY DOES NOT SWITCH THE CAR ON AT ALL

SOURCE: 2003 VW Golf won't start - battery was charged

You need to charge your battery up more. Either get a battery charger or leave the jumper cables hooked up for a longer period of time.
Your battery was probably completely dead. You might even need a new battery...they really don't like to be completely drained.

SOURCE: fog lights staying on

1st most newer car cars have a timer delay that helps light the area you are in for a couple of seconds. You may have had the knob turned all the way up on the turn signal switch. The same thing will happened if this switch is turned all the way up, the interrior light will stay on. Turn the lights on with the switch and see if the fog lights come on, do this without the car running.Trun the lights off,see if the fog lights stay on then go out after a while.if so you have a delay on the fog lights or relay. You may need to replace the relay only. Part $ 15 trace fog light wiring to relay usually under hood away from water sources.......runjoe

SOURCE: 2003 Galant Clicking noise when trying to start.

It is your battery it may not be completly dead but it is too dead to run the starter. It take 300 -600 amp to run a starter and 20 amp to run a stereo

SOURCE: Engine won't start. Dash lights flash rapidly when key turned.

the battery says 12 volts but may be dropping to 4 or 5 under a load...i would suggest jumpstarting the car and see what happens.the battery should read in the high 12 volts and not less than 9.5 under cranking. the dash lights go out on your car when starting,and the alarm will go off ,and disable the ignition if the voltage is too low in cranking the car because the computer will shut it down and activate the anti theft.....check your battery posts are tight. best of luck
