Hi Igor,
Please check this post fro the default unseal method. e2e.ti.com/.../1021684
Unfortunately if the pack maker has changed the codes, there is no way to figure it out.

Hi Igor,
The default password
0x0414
0x3672.
and full access is a two word command
0xffff
0xffff
are the standard defaults for all our battery gauges.
You may have to contact the pack maker, since they will always change this code from the default during manufacturing, and we do not have access to their codes.

Swami
