First hope I am not placing the post in a wrong place. Second I hope to offer some help for others. Here I want to talk about how to use VVDI2 to generate special chip for Buick Enclave, and how to use ND900 to recognize car key type.

Tools to use:

VVDI2 - used to generate special chip

ND900 - used to recognize key type

One original key and one new key

Step-by-step operation instruction:

1. Use VVDI2 key programmer 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”.

Secondly, use VVDI2 to generate it as special chip. Open VVDI2 Quick Starter, click on icon “Key Chip programming”.

Thirdly, click “Generate Special Chip”, select “ID46 Chevry Circle Plus – PCF7936″, click “Generate”, special chip is generated. successfully, confirm it.

2. Put the key with special chip into the coil of ND900, the chip type is recognized as “Encrypted 46, brand new unused, encrypted mode” So you can 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.

Hope someone would like it.
