I recently rented a new Corolla and noticed the key remote is one unit. Does anyone know if we can get one that will fit a 04 xB. I think the blank is a "47" or a "Yaris" key but can the buttons be programmed for the xB?

 

I now know that a TC key blank is the same but I cant get the remote to function, Even with the instructions to add a remote.

 

It's very possible the key itself will not work like you are after. There is a difference in the pulse timing as well as frequency. If you know the pulse rate and acceptable frequency range, you can get any RKE fob you want as long as it works on the same specifications. I do not believe there is an RKE/key unit that will work with the 1st gen security.

 

So far I think you might be correct. I talked to a locksmith that might be able to help but it doesn't look good. I got the key cut and it indeed works. I removed the transponder chip since the 1st gen xB doesn't have a need for it. After I get with the locksmith I will post the results.
