Sorry - but all my searches didn't help much.

Can anyone provide a link to directions to how the reprogramming process works for the RX400h?

I bought a uncut new key off eBay, and have a locksmith who I think can help, but I doubt he would have all the quirky directions to reprogram it. Any help would be sincerely appreciated!

Thanks

 

it will be easier to do it this from ebay. you get the keys and gather all your keys at hand,
let the dealer do the programming, you may have to pay the dealer.
