Do you need a BCM code for an extra key?
EXTRA KEY requires a valid key to disarm the Theft Deterrent to allow the new key to be programmed. On VY and VZ modelsthere is only one method of adding a key to the BCM > KEY CODE (NEW KEY). Important Note for VT, VX, VY and VZ: The BCM Security Code is required for “KEY CODE (NEW KEY)”. .
How is the ignition key stored in the ECM?
The ECM carries out the check of ignition key by special encryption algorithm, which runs in the transponder and in the ECM in parallel. Only if the results are equal the engine can be started. The data of all transponder, which are valid for the vehicle, are stored in the ECM.
What happens when you use an improper coded key?
If an improperly coded key (or other device) is used, the engine’s starting circuit will be disabled. When you turn the ignition switch to ON (II), the immobilizer system indicator should come on for a few seconds, then go out. If the indicator starts to blink, it means the system does not recognize the coding of the key.
Where can I find the key coding procedure?
– Key coding procedure is available in control unit IMMO – Immobilizer from “ECU Programming/Coding” menu. Teaching – Engine must be turned off. Key is turned to ON position. – You will be prompted to enter a 6- digit PIN code. (eg 123456, see page 2 – PIN codes) – Now you have the key in ignition in the ON position.
How can I test if the ECM is working or dead?
How can I test if the ECM is working or dead? Connecting an OBD-II scanner gives the code U0100 Lost Communication With ECM/PCM “A”. Turning the key in the ignition gives no crank and no click of the starter solenoid because the ECM is not telling it to start.

What causes no crank and u0100 lost communication with ECM?
All the trouble was caused by a mouse chewing through some wires under the battery and fuse box. I was just going to say to check the fuse box under the hood. Mine has rattled itself loose twice. Bolted it back down after inspecting for damage and everything went back to normal.
How to get Pin code when programming key?
Many devices can calculate the pin code by their programmer,you just need to plug the programmer into OBD socket to get pin code,then programming keys. Try to disassemble chip to read out pin code when you find the device can not support. Summary,when you get incorrect PIN code by VIN calculating:
