$100 does seem expensive, so I searched eBay for the key Check out the link at
http://cgi.ebay.com/ebaymotors/2006-...spagenameZWDVW, and you can see the part number is KEY PART#69515-AC020. I checked a couple of online dealers and found the part you are looking for for $20.87 at Hollywood Toyota in Florida (

You may want to call around. Good luck!
