Does Saturn use transponder keys?

Why does Saturn use transponder keys?

car anti-theft Saturn transponder keys used mainly as an anti-theft technology. The immobilizer configured to accept each unique programmed key by a code. When a key with unmatched code turned in the ignition, the vehicle will not start.

How does PASSKey works?

In Passkey system is actually not a transponder, but very similar to the VATS! The Theft Deterrent Module validates the resistance of the chip in the key. The PASSKey includes more that a 100 resistances.

In addition to the resistance check, PASSKey also use the PASSLock system as an extra safety feature. The PASSLock module and measures and record voltage data through a magnitude sensor placed on the ignition. It basicly check the proper key cut profile and determines if the cylinder is aligned. If the PASSLock recognize the key it will allow the car to start. This is effective when cylider is broken, damaged or picked usually by a thief trying to hotwire the vehicle.

How does PASSKey II works?

PassKey II works like the PassKey I, but the TDM is built into the BCM instead of the ignition. The BCM sends a digital start/no start signal to the PCM over the data bus. One more change from PASSKey I is that halting the engine done by the fuel system instead of the ignition.

How does PASSKey III works?

The Passlock III is actually the first transponder used by GM. The chip is located inside the plastic covering of the key and stamped "PK3" on the metal blade. The ignition lock cylinder contain an antenna that reads the transponder data and sends a it to the PCM. If the PCM recognize the code from the key, it will allow the engine to drive. Some higher end models use a key fob instead of metal blade.

Later version of the PK3 called PK3+ or + have the same infrastructure and fuctionality as the PK3 system. The only difference is that the PK3+ use an encrypted transponder and requires dedicated programmers.

Can you program a transponder key yourself?
