What is the vehicle, vin and module these came from?dmaxben wrote:Hi, does your tool work for 5-byte device control keys too? Or just 5-byte programming keys?
Here are some valid device control seed/key pairs... I can provide more valid pairs if needed.
seed...................................key
15 56 17 BC 01..............3C DD 23 18 A2
BB 53 2B 4F 01............13 7B 24 C0 20

The above seeds use the newer 01 ending, I can still calculate them but need to know details about the module to identify algorithm number to use.

When you say "device Control", are you referring to the "AE" control mode? Or is it a different mode you are referring to?dmaxben wrote:It seems some of the 2017+ BCM's use the seed ending in 0C, and others use the seed engine in 01...?
Heres another device control seed/key pair for a BCM.
VIN: 1GC1KWEY3JF171209
Device control seed: 1CA30AD90C
Device control Key: 623675209E
Programming seed: 70BDDB5006

Yes, the mode-AE device control.Tazzi wrote:When you say "device Control", are you referring to the "AE" control mode? Or is it a different mode you are referring to?dmaxben wrote:It seems some of the 2017+ BCM's use the seed ending in 0C, and others use the seed engine in 01...?

I know the programming 5byte algo, thats the standard 06 type.
Ohhhh I see. 27 03 is actually called engineer/manufacture access. I was not aware of the 2017+ locking out after moving though, thats a new one.dmaxben wrote:Yes, the mode-AE device control.Tazzi wrote:When you say "device Control", are you referring to the "AE" control mode?

On 2016 and older BCM operating system, the AE device control (to command lights, etc) is allowed any time.
On 2017+ BCM operating system, the AE device control is disabled when engine is running and/or vehicle speed is above 0.
If you request device control security access (02 27 03, BCM returns device control seed....then send the proper device control key with 07 27 04 AA BB CC DD EE), the BCM will then allow free operating of mode-AE device control with the engine running.
Is it possible to figure out the device control seed/key algorithm?
