Paulkooi,
Unfortunately there are no shortcuts to your problem. The chip in the key is a resistor that drops a voltage signal down as it passes through and is then verified as correct before allowing your car to start.
A VATS key interrogator is used to determine if your key or ignition switch (w/anti theft), is at fault. Here is a picture of one.
It is however likely that your vehicle has the same problem 95% of these vehicles exhibit, that is simply the ignition lock cylinder (w/anti theft) has a broken wire from turning so many times. I do not recommend this for the amateur mechanic and a variety tools, puller lock plate depressor, are required for service.
Have a shop skilled at dismantling steering column take a look at it. It may also be a good idea to check for shops that own this old key test tool also.
Good luck,
