Program 2008 VW Passat ID48 All Keys Lost with iProg Clone

 

Here’s an easy way to program new key to a 2008 Vw Passat under all keys lost situation with iprog clone programmer. it may work on other cars.

I had a used OEM Key from another car. Just removed the board, and put it in a new shell case with Xhorse Super chip that I Generated as TP-23 VW Megamos 48.

The procedure:
–         Remove the BCM that is located behind the glove box.
–         Read the eeprom 95320 (You don’t need to unsolder it, just read it with any programmer. I use the Revelprog programmer, I like it)
–         Save the original bin file (I usually create 2 original files, just in case)
–         Open the iProg and in the menu, choose CAR/Key/Key auto and VW.
–         Select the Passat Megamos 48 (Select one that works for you)
–         Load the original Bin file that you saved from the BCM, and click View ID: (The iProg will decrypt the file and it will show the CS, Login code, and the VIN Number:
–         Connect the RFID adapter with iProg (Make sure that the jumper on the RFID Adapter has to be in AUTO)
–         After you connect the RFID read the Chip 48. The message should be “The Key is not in this IMMO”, if you have message “Bad Transponder” is used key, if you have “No transponder” try to move the key to find the right position until you get the message “The Key is not in this IMMO”

In my situation, the BCM had two keys, so I wrote the new key as Key 3, saved the new file and wrote it back to the BCM, I went to the car and I saw in cluster that only my key was programmed 1-3, so I wrote the same key three times.

Back to the procedure:

I preferred to use Xhorse Super Chip XT27A, every time you generate the chip, it will take different ID, so you can use only one chip for all of the following steps:

–If your BCM has two or 3 or 4 keys in memory, you have to follow these steps:
o  Write Key 1, save the file as key1 or anything you want, Click View ID and you’ll see that the First Key ID will be changed to the new key which match with the ID from the chip.
o  Generate again the Xhorse Chip to TP-23 VW Megamos 48 (it will get another ID)
o  Write Key 2, save the file as key2 or anything you want, Click View ID and you’ll see that the Second Key ID will be changed to the new key which match with the ID from the chip
o  Generate again the Xhorse Chip to TP-23 VW Megamos 48 (it will get another ID)
o  Write Key 3, save the file as key3 or anything you want, Click View ID and you’ll see that the Third Key ID will be changed to the new key which match with the ID from the chip…..and so on.

If you have finished with replacing all keys in BCM with the new ID taken from the Xhorse Chip, write back the latest file you have saved to the BCM, install the BCM back to your car, and start the car.

No ABS Coding Lost

This is optional:
After that, you can use a Key Programmer to get the immo data, and learn the new key, so your car will have the key you want, not all keys programmed from the steps above.
