Car electrical systems dying.
Check the battery voltage between the engine block and positive, with the engine running it should be over 13volts. Now check between the battery positive and battery negative, should read the same, with the engine off and in fault condition, It should read more than 12volts, if it does, check from positive on main fuses and chassis, you should get a similar reading. If you do and the voltage rises when the engine is running, the alternator is fine otherwise replace the brushes and diode pack in the alternator.

We have a 1989 toyota camry the key will not turn
Sounds like the ignition barrel has failed.
If you replace any part you must ensure that the key and the transducer ring are matched. If not, the immobiliser will come on and you will never start the car.
Get a diagnostic test to verify the immobiliser is turning off.

AC and Cooling Fans Not Working
Try installing a jumper across the N/O terminal at the relay socket. Temp sensor in the radiator or in the thermostat housing supplies the signal for the relay the other relay signal is supplied by A/C in on position. both fans will run continuous with A/C on. One fan runs intermittent relative to water temp. Be careful not to blow a head gasket. If you leave the jumpers in place, the fans will stop when the ignition is turned off, save the engine until you isolate the relay signal problem. then simply remove jumpers and reinstall the relays
