No such part exists on a Durango.
It is the choice of the installer where to install it.
You will need to unplug the connector on the hood switch. That is how you can override on an Acura Vigor.
It is usaully in the glove box on most cars check in there, it should be a little round button
If your refering to the over drive button. It's located on the shifter handle.
There is no such part on a Chrysler Sebring.

It is when you do not want your guest to have access to the internet.
On the top in the center
It doesn't exist.
For most vehicles the valet/overide button/switch is located somewhere hidden underneath the stearing wheel area. It is usually hard to spot, but it is there somewhere.
Press the button- then lock the glove compartment using your normal key, Now the trunk button down on left by the fuel door release button will not work - if you have the original "valet" key that came with the car, you can give it to a valet parking attendant and they cant get in the trunk or the glove compartment (of course you can't give them the key that you normally use which can open everything).
There's a (fuel door) button on the dash (toward the center), next to the trunk open button. But both these buttons are disabled if the valet switch in the glove box is depressed. See to that valet switch (button) first.
