AutoTransponder.com is a great site for ordering whateve you need and very reasonable. They have any type of auto. The Lexus RX300 remote shell with the key blank I think was $19.95 and they will also cut the key for 29.95. They have a live chat or an 800# for any support or questions. They do require proof of ownership etc. Or you can get the key blank cut locally by looking at AutoLocksmithFinder.com for a laser locksmith in you zipcode. Their prices vary around $45 for cutting a blank.
