So hello fellow IS300 owners, it's my first post on here and I'm wondering how did you guys fix the infamous "Cracked Key" problem, since my key decided to give birth and cracked...

 

i bought a new shell, swapped over the internals (button pad) and got the key cut at the dealer

 

Lol thanks I hope the new key lasts . Idk why lexus designed it that way..

 

I broke mine few weeks ago, and I just got a new shell from Sewell. I just swapped the transponder, works fine

 

So I actually went to the Lexus dealership with a new shell and everything, they refused to cut it and said they did before for $50 but the metal on the keys bought on the internet apparently broke their machines. So I had to pay $92 including tax to use one of their shells :/ . It's great quality but it's like $92 lol.
