Hello Peter. Thank you. No, I don't have another key. But I have just called a locksmith that claims he can make a new duplicate for like $75USD programmed as the Admin Key. He will be here soon. I'll let you know how it went.
Hello, my problem is finally SOLVED. It wasn't free, but it was cheap. Short story, I called a local locksmith who charged around $75USD for coming to my home, make a duplicate of my key and program it as an admin key.
Here are some take aways explaining the problem and solution:
1. I got only one key when I bought my used truck. At this point, I don't know if this was the admin key or not.
2. After messing around with the menus, I activated the MyKey option.
3. Activating the MyKey option limited my top speed to 80mph and the sound volume as well
4. Activating the MyKey option made the MyKey menu disappear.
5. Basically MyKey is a nice feature that will allow you to limit the key you lend to someone (to your son, perhaps) for extra safety. Obviously it is impossible to remove this restriction using the same key, which will make the MyKey feature pointless.
6. So, having only one key and activating the MyKey feature will limit your truck (speed, sound volume) and you won't be able to undo it.
7. I got a duplicate key, which my lock smith told me, was programmed as an admin key
8. I turned on the truck with the original key, still no MyKey menu
9. I turned on the truck with the new key (admin), the MyKey menu showed up!
10. Using the admin key, inside the MyKey menu, I was able to clear the MyKey feature (I do not remember the exact name of the option, but it is very self-explanatory)
11. After clearing the MyKey, I turned on the truck again with the original key and the MyKey menu showed up again
I hope this helps. Thank you all!
