do you know what style the immobiliser is?  passlock II?  passkey III?  what year is the car?  There will for sure be a module you can use to bypass it, just need to know which one!

It sounds like it has VATS if you are saying the key that broke had a chip in the shaft. that chip or pellet is actually a resistor and if you want to bypass this you need to measure the resistence of the resistor on the key. That is if you still have it. If you do, then you can permenantly bypass the system by placing a resistor across the two very thin white wires coming from the key cylinder. the 2 white wires are found in the main ignition harness and they are in an orange casing that actually looks like a single thicker wire.

Good luck
