How do you turn off a running locked gmc Denali from the outside?

To turn off a running locked GMC Denali from the outside, you can use the key fob to press the lock button twice, which typically engages the engine immobilizer. Alternatively, if equipped, some models have a remote start feature that can be disabled by pressing the remote start button again. If these options are unavailable, access to the vehicle may be required to use the ignition key or a method to unlock the doors. However, tampering with a locked vehicle is not recommended and may violate laws or regulations.
