SKP900 failed to work Toyota Crown 2003 smart key

Hi all, how to program Toyota crown 2003 smart key? I tried using skp900 key programmer, but skp900 doesn't work smart system, i using used key.

Here are the suggestions of some experienced locksmiths:

1.

MKlll Device + Toyota Lexus Smart key software = 3800 USD

2.

why would any one go for MKIII Device at 3800 usd better purchase a Zed-full which has more options



But the cost is prohibitive for MKIII to only Virgin used smart remotes. Zed full has more features like you can use dump files to add more smart remotes.
