@Mr.locksmith In the US there is a 2 hour wait on most of the 23+ Suburbans,Tahoes,etc. There is no clear answer but certain trims will make you wait 2 hours even when using GM software (SPS2) Even some 21+ can have the wait if they've had their modules updated. I wasn't sure if getting code with a 3rd would eliminate that 2 hour wait.
The big question... Where fk obtain the 3rd party pin codes. How much are they? How quickly do they provide the code, especially knowing that you must sit there waiting for one code, then another. Is total time about 30 minutes if all goes smoothly? Thank you.
