I just bought a 2007 Toyota Sienna mini-van..... It only had one Key since the Key has achip in it ( like the Spyder ) an ordinary key from the hardware store won't work in the Ignition ..... so perusing the inter-net I found some folks who showed me how to DIY it. Bought two spares on amazon for 15.00 and I will have to have them cut. But this info was a real find …..later ...Mike ...…….PS the cars own computer does the Transponder code entry thing
