Okay, then this isn't a factory system as you stated in your other post. The OE system used at the time used the key and a remote control that locked and unlocked the doors and would only sound the horn. Anything that uses a plug-in device would be something that a dealer or someone else added after the vehicle was built. There should be at least a manufacturers name on the socket, but you may need to remove the lower dash trim panel to find where they placed the actual module. From there it will usually have the model number on it, then you look that up and get the install directions or look at the wiring to match up the colors that they cut and added this device. The few of these I've seen generally cut the circuits to the ignition, fuel pump and starter. Then it depends on the actual unit, some the "chip" is the actual bridge item, it completes the circuits that were cut. Others use a version of the anti-theft tags used in stores, the device powers up, reads the tag and closes relays or transistors to complete the circuits. Take a picture of the chip you have and the socket and post them on here. Then if possible you may need to remove the lower trim panel to find the module and remove it. I doubt you can get any replacement parts for it as these type units fell out of use fairly quickly when manufacturers added the OE systems to everything.
