if you have a visible chip on the key (resistor), the car may not be able to read the signal and go into fail safe mode.
Also try to unlock the car from the drivers door to see if there is an alarm issue. The disarm wire is attached to the key lock cylinder in the drivers door.
I too own a '93 Sedan Deville. I had the same problem you are describing. There are so many brands of remote controlled systems that your problem defies a simple solution by someone like myself not in the business..I went to a store where they specialize in audio equipment and alarm systems. A good tech will be able to program your system in a New York Minute. There might be a small charge. Audiovox manufacturers systems under many different names. Their customer service people are pretty sharp and if your unit is of their manufacture they will be happy to walk you through the programming system on the phone. I have done this myself and they will stay with you 'till it works. IF it's an Audivox system their customer service phone number will be molded in to the key fob. Hope you find this helpful.
I've not done this for the reason you speak of, but I was told to disconnect the battery from both terminals and hook the 2 cables together and leave it that way for 30 minutes making the computer forget what it was doing. Reconnect the battery and find if it worked for you. There's no power anywhere when the battery is disconnected, so no harm is done. This method turned out my ABS light when nothing else worked after repairs were done.
hard starting first start of the day , sitting over night ? Fuel pump . Check valve inside that is suppose to keep pressure in fuel lines to the fuel injectors . Checking with a fuel pressure gauge is the proper way to test , not guessing and replacing parts . Your best bet ,take it to a qualified repair shop. Can't help your on a
low fixed income . You could spend alot more money if you don't.
So do yourself a favor .
Testing for failed fuel pump check valve
Who told you that you need a P/S cooler? What are your symptoms? When this much work is involved, never install used parts. Did you disconnect the - negative battery cable before installing the alternator. Arcing will damage the diodes in the alternator. An easy test of alternator output is to hold a paperclip to the rear bearing, if its magnetized, its working. The hoses for the cooler don't matter about the connection, the cooler is in series with fluid flow. Just route the hoses neatly with no kinks near the cooling fan.
The most common cause of this is that the air temperature control door (called a blend door) is stuck or the tiny electric drive motor that moves it is defective. You will need a good shop that fixes AC/Heater issues to diagnose this, I am just guessing based on past experiences with GM (Olds and Cady) cars. A picture of the little drive motor is below, the door it moves connects to the hole that has white.
fuses blow because the current flow is in excess of the fuse rating and that is normally from a dead short in the circuit after the fuse
I suspect that the ac compressor rely is faulty and I would start looking in that area

You will have damaged some of the critical electronic components on the engine when you connected the power source up the wrong way.
Until you identify and replace all the damaged components you will not be able to start the engine. To begin with the starter motor solenoid and starter motor will most likely be damaged. You would need to check with a mechanic or auto electrician on all the items that will be damaged as a result of connecting power up incorrectly.
A ruptured diaphragm in the fuel pressure regulator will let extra gas enter the engine through the vacuum line to the regulator. Pull off the regulator vacuum line. Any evidence of gas? Let the engine idle a couple of minutes with the vacuum line off. If any gas starts coming out of the vacuum line nipple on the regulator, then that was the problem. Replace the fuel pressure regulator.
