Tow it to the dealer, they have the code to deactivate the alarm system.
A lot of GM models of that era can glitch if say, the window was down and you opened the door from the inside the. Tried to start it.
So aftwr trying to start, roll up all windows and close it and lock it from the fob.
Then hit emergency button if your has it, then hit unlock to clear the emergency. Then lock it.
Wait a few minutes and approach it as normal and see if it works. Also, if your fob battery is more than a year old replace it. Best wishes.

I just had this same problem with a '96 . do you have a vats key in your '94? you need to bypass the VATS system. read some of the blogs on this site and it will tell you how to do it. I fixed mine with a $2 resistor from radio shack.

the wire that goes to the ignition to the anti theft device is probably broken if you call a good locksmith they can go in through the steering column and fix it same thing happened to my 95 eldorado apparently cadillac designed the anti theft system to coincide with the ignition and is connected to the ignition with two wires that turn as the key is turned the wires twist and eventually they wear out
