Question:
Question: I need to write key on Volvo V70 1998- with 93С66 and pcf7935 with Xhorse vvdi2 key programmer. When loading eeprom data, free positions 4, 5 and 6 are not available for writing. How to solve this issue?
I’ve got a five-button GM flip key, it’s actually locked to a vehicle. It can’t be reused until it was unlocked. So I’m gonna use the Xhorse Renew Adapter here working with VVDI Key Tool Max to unlock it.
As you can see, the GM proximity card is indeed locked.
To unlock key, it needs to disassemble the key shell and take out main board.
Put the board in button side up properly on Renew Adapter.
Go back to Key Tool Max,
Special function >> Remote renew >> Buick Chevrolet >> 5BTN smart key 315Mhz F7952E >> Unlock
Note: If it didn’t identify the key and renew failed, try to press down the pins of board that are actually spring-loaded. Push down on them to make sure the pins contact are good.
It’ll process automatically…
Renew success.
Such quick!
Let me read transponder again, look, it is unlocked.
Done!
So now I can reuse the key to other vehicles. The Renew Adapters Set is including 12 adapters, supports to work with VVDI Key Tool Plus or Mini Key Tool for different original remote keys unlocking.
Today I’m gonna to use Xhorse VVDI Key Tool Max and the Renew Adapters Set just purchased to unlock an OEM Dodge Fobik key. Once it is unlocked, it’ll be able to learn to another car.
The Renew Adapters Full Set has 12 adapters, with this particular set you can do all kinds of vehicles. Instead of having to solder wires to the board, these adapters actually just line up the board where it needs to be and allows the Fobik to be unlocked.
How to unlock Dodge Fobik key?
Here is the OEM Dodge Fobik key.
