I lost all keys. Suggestions?

I think I have figured out cheapest option to get replacement keys with all keys are lost, master key included.My understanding is the key can be cut from anybody but also has to be programmed for the transponder and keyless entry. And there is especially difficult when you don’t have a master key. I think i can program a copy manually if I did have the master, is that correct?
Because I don’t have a master I think my best option is to order a key with keyless entry online and have a local locksmith program it? To avoid programming cost, is there an affordable techstream software I can order to just program keys?
Is there anybody in the Memphis area that does have techstream that I can pay to program a key or use their software?
Is there any suggestions for a local locksmit in Memphis that can help?

 

I for one would not discuss this on this forum. You may be legit, but something about this post stinks. If i am wrong you will get an apology, if i am not wrong well you know.

 

I dont' know what year is your vehicle but techstream you still need to pay seed codes.
