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.

Replace ignition lock cylinder and chip key. The wires have broken.

If the antitheft system is armed and isn't recognizing the key for starting, the dealer should be the next place it should be towed for reprogramming the key to the computer.

I had the same problem. trying to save money i took it to several auto places who thought they could fix it..... after a lot of money and my 800.00 after market alarm was taken off i had it took to the dealer . They fix it in two hours they put in new switch and key haven't had any problems sence.
Hello Jaclyn...Look under the dash area for a button or, a toggle (valet)
switch. When you locate it, turn on the ignition key, press and hold in the button (little spring loaded micro button, red or black possibly)
until the alarm chirps 1 time. This should over ride the system, and only the keyless entry part, if installed, would still be operating....The LED light in the dash should also go on solid....At this point. the alarm would have reset.
If this had a starter kill relay installed it would now be opened, and the engine would turn over when tried.
You would repeat these steps to go back to user mode to see if this was corrected...i hope this information is helpful...Happy Holidays.
