Prius key

[jodge]

I'm not familiar with the prius keys at all.
I have this key but not working, no tp no remote.
Tokia Rika B31EA

i have a few questions
It's just a remote w/o tp, like Smart 450?
Can i reuse used remotes?
Can i use different type Tokai Rika remote?
Can i use a 3 button remote (with red button) to a 2 button system? (and vice versa)
thx

Key and proxy use the same calculator, just the key can be bypass reset time. That why the proxy system can not bypass the reset time. There too many modules that have to time out before the info get pass on to the next module.
