If the device is locked, it will not let you open the diagnostic menu. Also certain carriers like Verizon and Sprint have been known to block the feature completely.

The device is not locked, am using it and want to unlock KG locked, when am connected to wifi the phone locked, so before the phone connected to wifi, i want to enter into test mode, it will let me at least for 30 minutes to lock after connected to wifi network. Within this 30 minutes i want to remove KG lock using Griffin unlocker

Try *#*#88*#*#.
That's another test code and works too.
