So many inquiries about Estima keys! (Including myself) http://www.wholesalecarkeys.net/side-1-button-remote-key-for-toyota-cadina-estima-harrier-28050-26010-30050.html is where I have ordered a new key for my 2002 Estima. Waiting to see if it works. Cheaper the the $150 quoted for the same thing from local locksmith. And link to forum below has info on programming your key (hopefully) http://www.teoc.ws/community/topic/33207-reprogram-estima-remote/ Knowledge is power, these forums, and the wonderful sharing people on them have saved me HUNDREDS so far, and I have only had my Estima two weeks!
