Tools to use:
ND900 clone machine- used to recognize key type.
VVDI2 key programmer by Xhorse – used to generage special chip.
One original key and one new key
Step-by-step operate instruction:
This is Buick Enclave car.
See following picture, the left on in the hand is car owner’s original key, and the right one is the key that is programmed.
Just now a peer put a common 46 chip into the key and then program without success, actually, it is special chip.
Next, I will use VVDI2 key programmer by Xhorse to generate special chip.
Firstly, insert the key with common 46 chip into the coil of ND900, the chip type is recognized as “46 brand new unused”, see picture as follows.
Now I use VVDI2 to generate it as special chip.
Open VVDI2 Quick Starter, click on icon “Key Chip programming”.
Click “Generate Special Chip”, select “ID46 Chevry Circle Plus – PCF7936”, click “Generate”, special chip is generated
succefully, confirm it.
Agian put the key with special chip into the coil of ND900, the chip type is recognized as “Encrypted 46, brand new unused, encrypted mode”
Next is to get on the car and program key manually.
Firstly, insert original key into ignition, turn on, wait till the immobilizer light off.
Then, insert the new key into ignition, turn on, wait till the immobilizer light off. Then the new key can start the car.
After the key is tested working, again put the new key into the coil of ND900, you will find “brand new unused” after “Encrypted 46” disappear.
Wish it helps!
