What does the dealer say?

Consult a qualified locksmith.

dealer thinks my locks on ignition and doors where changed thats what they said and yes i brought my GMC Original key which is below here my original key

i got the key code from the dealer printed out if i bring that to a locksmith to rule out the dealer cut it wrong with the key code would a locks-smith be able too? or can anyone pm me they key code to compare with what key code the dealer printed off for my VIN?

If they used your VIN then it should be correct. Maybe check with another Dealer and see if the code for your VIN matches. Could just get the new key cut from your original key and let it go. Depends on what you are trying to accomplish. Good luck.

Yes I will try a locks-smith / other dealer just to confirm if the key code has been changed from my vin, its all because my ignition is sticking and dealer said to try a new key cut to code before buying the whole cylinder with keys the part number they gave me for that would be15799769 https://www.amazon.ca/Genuine-15799769-Ignition-Lock-Cylinder/dp/B00GU9YQEG

Does your original key look the same (cuts) is not go back to the dealer and have them make it right.

Guys I have an update went to a automotive locksmith and he confirmed that my vin and key code are right for my vin and he looked at my current key and can tell its a totally different key code which is why the key cut to vin doesnt work at all, my question how is this possible if even the airbag on and off switch works with my current key and the spare tire lock on the bumper so bottom line is someone went to great lengths to change all locks to match my current GMC key so if i want to go to what my vin says i have to change everything or just let it go like one guy said in the thread and just get a new key coded copied to what i have now, ive owned this since April 2003 so looks like prior to me owning it some monkey business went on and now key code to vin isnt so, when the time comes where I cant turn the ignition lock cylinder not sure what to do best would be to go back key code i think would make sense any thoughts and input from you guys is helpful

The air bag switch isn't keys to any specific key its generic, You simply got the wrong new key cut take it back. Buy some lock ease and squirt into the column lock cylinder to lubricate it.
