Servicing the 2001 VW Cabrio

Once the correct chip is selected, turn the device on and it will connect. Press enter when prompted to. It will then start to read and if successful it will begin a “Smart Recognizing” process. It will then identify the chip it is reading and ask the user to press “Enter.” It then comes up with specific information regarding the chip it finds. In this case it finds the 44 Crypto chip and asks that the user press “Enter” again.

Next, select “From EEPROM to Chip.” It will then ask that a Blank PCF7935 (44) chip is inserted into the Zedbull device. It will load the data onto the chip to start the car. It will go through the Writing process and say “Successful” when done. At this point the transponder is properly coded and can be used to start the car; the Zedbull can also be used to determine the PIN code to the vehicle by selecting “Calculate PIN Code.”

Photo 13 shows where the transponder rests in the head of the key, which needs to be removed and inserted into the Zedbull Device.

Most vehicles on the road today contain an ICU (or similar computer, also known as ECU, PCM, or SKIM depending on vehicle manufacturer) which has a similar memory chip as the one in this vehicle. By finding it and pulling the necessary data off of it, the necessary transponder can be programmed to start the car. The difficult part of this process is often simply finding the chip and putting it back again—the rest is pretty straight forward.

As time goes on there will be more and more requirements for this process. At the time of this writing the new 2011 Journey, Charger and 300C came out with Fiat 500 software. Nothing will program them at this time other than dealer equipment which is quite expensive.
