Is there a relay under the dash for the ECU or immobilizer?

Hello there, here are the diagrams for the entire (anti-theft) security system. There are a number of modules, switches, motors and relays. Hopefully this will help.

Lost my key, bought a new one. But still trying to figure out a way to somehow reprogram the immobilizer with out spending any money that I really cannot afford.

As you can see by the wiring diagrams there is no relay if you have a new key it must be programmed most shops will do it for about $130.00. Sorry, it cannot be done any other way.
