I've noticed trying to lock or unlock a cred chip while inside a vehicle causes a syntax issue where the command assumes you're speaking about the vehicle. I tried variations suck as 'unlock d-fense with xxxx', 'unlock wsb with xxxx', 'unlock cred with xxxx' and more with all the same syntax feedback.
Syntax: 'lock/unlock [Here, all, front or back]'.
If this is intentional then please feel free to delete, but it didn't seem correct having to leave a vehicle to unlock a credit chip in order to have a chyenless transaction just to then hop back in.
