When I got my truck I just went to the local locksmith.... not the hardware store.... and they made me a new key without any trouble. I'll attach a photo so you can see the key blank number. I had to narrow the bow on the key to fit in my key case, that's what the cut on the right is for. As long as you have both pieces of the key locksmith should be able to copy it for you. If you need more let me know
