2 keys to unlock doors/hatch/ignition (only want one key)

[Cigar_Maverick]

Hello,
Struggled with a title for this, so I'll try to do better in the body. I have a 2006 Yaris 2 door lift (hatchback). I bought it used about a year ago. It has 2 x different keys. One operated the hatch and the other works the 2 x doors and the ignition. I ASSUME (hopefully) that it only had one key from the factory. In which case I'd like to get back to that setup. I stopped by a locksmith today and asked them what it would cost. He said STARTING $250! That seems a tad pricey. It there an easier/cheaper way to do this? I just want all the locks/ignition on one key.

Thanks in advance,
Russ
