All sorts of ideas here. You need an auto electrician with a pro grade scan tool computer to sort that mess out.

You could try a reset again.

Disconnect both battery leads for 10 minutes. Hold positive and negative together for 2 minutes. Connect positive lead. Connect negative lead. Reset security system.

Try having a new key cut using the key code, at a dealer, not tracing the old key.

the fan is not operating properly
if it is a viscous fan hub( fan clutch ) replace it
if electric fans check the relay/s and coolany temperature sensor for correct operation
chweck all wires for continuity and connection faults

Sounds like your electric cooling fan(behind the radiator) is not functioning. The thermostat might not be working,making the fan
not come on at all. I once put a toggle switch in my dash,when I had
an old CRX, just to turn on the fan, or it would overheat.

your heater has apparently restricted the coolant flow....hopefully a good system back flushing will cure the problem....use a flush obtained from a parts house....I would buy the hose kit for flushing as well...good luck to you

if you havent already, repalce your thermastat sounds like the problem, hope this helps

replace the 02 sensor

COULD BE COOLANT SENSOR,HEAD GASKET,CHECK THE TIMING,THE PROPER MIXTURE OF COOLANT,WATER PUMP.DID YOU HAVE IT CHECKED OUT?ANY LEAKS?HEAT WORK WITH FAN?

sounds like either a faulty igniter or air/fuel sensor
