The keys come from the same factory, so physically they will work. Electronically is a different story. If its the flip key model you're talking about you HAVE to get the key from the dealer. (alternatively see below)
The transponder in the key is part programmed for your vehicle and the locked. It can ONLY be used with that vehicle.
Some transponders can be unlocked with tools like tmpro, but you still need a dump of the software in your code unit in order to create a new transponder.
Alternatively and probalbly the best solution is to mail off your code unit to one of the locksmiths online offering a key generation service.
