Ordered a new master smart key for my 04 LS430, can I program it with my master key?
I have only had the one master smart key since I bought my LS and have always been worried about if I lost it what would I do as I have no backups, so as I was already placing an order with Sewell for other stuff, I ordered an additional one and precut. Is it possible that I can program it to mimic my key that I already have since theyre basically both the same thing?
