    Hello,

    I was replacing key fob for my smart key and lost RHID chip.
    Does anyone knows type and frequency of Toyota Prius gen 2 RFID chip?

    Is it possible to reset/reprogramm RFID with Toyota Techstream? I have TS and a cable.

    Car is fully operational because I have Smart Key, but if Smart Key will die it will be impossible to use car.

    Thanks in advance.

    I really hope you get an answer. I have a key that will not work in the key slot but will work anywhere else in the car. If appears to be an original key. So hopefully somebody here can help you out.

    Thanks! I guess I'm just out of luck on that particular key fob. I don't want to break open the case on that key. I'm pretty sure it's the original one as it looks very old and has the silver Toyota logo on the back. I'm pretty sure they're epoxied together or something.

    Luckily I do have a second key which works perfectly for all functions. I'll keep the other as a backup. ​

    Fobs have a replaceable lithium button battery inside which lasts around 5 years. The case is waterproof and designed to be opened for battery replacement. There is a button on the side of the fob case to release the metal door key, and when you remove the key it reveals a pry point slot which you can then use the bottom of the key to pop open. This is all covered extensively in the owners manual.

    With empty key fob battery you could drive with the key in the slot. But not with the key out of slot. And you couldn't use the buttons to unlock (or lock) the car. So that would be basically opposite situation for what's talked about in this thread.

    And what you are describing is more or less an emergency procedure to still be able to start the vehicle. Normal operation would be with a battery in place of course. Finland, eh? I have a family tree that started from roots in Finland (family name Paas which got changed to Blomquist when they emigrated). But I believe my original roots came from Sweden.

    Actually had to look that up. There are about 120 people with family name Paas in Finnish system. With 70 of them abroad.
