If you have a black chip in your keys (you can see a little pellet in the shaft, close to the head) you have the oldest version of the PK system. That pellet you see is actually just a resistor. There's only like 15 different values they used. When you insert the key, 2 fingers touch that pellet. One on one side and one on the other. Then the BCM reads the code.
One of the common failures is gunk in the ignition so squirting anything sometimes can work. Mostly just compressed air is all you need. The most common problem is the wires inside the column break. For that you either need to replace the ignition lock or bypass the system using a resistor with the matching resistance.
