Xhorse XDNP61 Adapter Cannot Read Porsche KESSY Module Solution

Problem:

Recently did all keys lost on a Porsche Cayenne with the Siemens kessy. Xhorse VVDI Key Tool Plus  failed to read KESSY data using XDNP61 KESSY solder free adapter.  I did try to read in circuit according to diagram, no dice. Ended up removing the 93C86 to read out of circuit and got it done. Anyway, has anyone had luck with this adapter to read board without desoldering chip? Or is it not worth messing with since removing eeprom is so quick?

Here is the clue.

1).

Your kessy module is an early one, otherwise reading the eeprom would not have worked!

No adapter will help. These are for in circuit reads on Continental kessy.

Yours is a very late Siemens KESSY and so the only really reliable way is to remove the eeprom chip and read out of circuit.

2).

If VVDI Prog fails to read in circuit, to read write in circuit just need to lower voltage to 3.3 to 3.5. When voltage is at 4.5, the crystal oscillator interrupts the chip.

Read KESSY data with vvdi prog in circuit and make key with VVDI2.

3).

You can read the KESSY module with a clip. One of our customers read it using a Key Tool Plus with a clip, and that was successful.

Then created a dealer key and added a key via OBD2.

Add 2023 Kia Carnival Smart Key with VVDI Key Tool Plus

I’m working on a 2023 Kia Carnival for a customer who has one working key. We sourced a new OEM smart key with sliding door buttons, and I’m using the Xhorse VVDI Key Tool Plus to add it.

1. Read the Smart Key PIN Code

The Carnival uses a 4A smart key. If you’re unsure about the transponder type, read the key before entering IMMO programming.

• On the Key Tool Plus, go to Immo Programming >> ASIA >> KIA >> Read PIN Code >> Password reading (ID 4A smart key) >> Start Programming >> Read PIN code.
• If connected to the network, click OK. With an existing key, switch the ignition OFF and then ON. If all keys are lost, turn on the hazard lights and close the driver’s door once.
• Click OK and wait for the PIN reading to finish. Switch the ignition OFF when prompted and note the PIN code.

PIN code: 363065

Workshop Note: Hyundai/Kia key programming erases all existing keys and remotes. Ask the customer about additional keys beforehand so they can be added back.

2. Enter Smart Key Programming

• Go to Select by model >> US market >> Carnival (KA4) >> 2022- >> Smart keys programming >> Start programming >> Smart keys programming.
• Enter PIN 363065, then press the Start button once as prompted.
• Switch the ignition OFF, open and close the driver’s door once, and confirm the network connection if requested.

3. Match the New Smart Key

• Within 5 seconds, hold the smart key’s indicator-light end against the Start button for 5 seconds. The immobilizer light will flash during matching. Position the original factory key vertically; for some aftermarket keys, use the back of the key or remove its shell.
• Once the tool displays “This start key has programmed successfully,” select Yes to program the next key and repeat the matching procedure.
• After programming all keys, select No to finish.

All smart keys must be matched to the vehicle; an unmatched key cannot start it.

4. Verify Key Operation

Test both smart keys. Both started the vehicle and worked properly.
