If you hear a siren sound, then you have an aftermarket alarm, if this is the case, you need to locate the override switch. This is usually located under the driver side portion of the dash. Ford installed Code Alarm systems in the early/mid 90's. If you locate the switch (black push button) then put the key into the ignition, turn the "on" position and press and release the button, this (if working properly) should disable the alarm and allow you to start the vehicle. I hope this helps, and let me know how it goes. If for some reason you have an alarm other than Code Alarm, let me know and I can walk you through disarming that too. Good luck.
