Security System & Immobilizer
Lexus shares Toyota’s immobilizer lineage — 4C, 4D67, G and H transponder eras — topped by Smart Access proximity fobs on push-to-start models.
On the CT 200h specifically we see: Texas Crypto 4D (4D68, DST80 “G”). A correctly cut but unprogrammed key turns the locks and never starts the engine — programming is the half of the job that matters.

Lexus CT 200h Key FAQ
I lost the only key to my CT 200h. What now?
We come to the vehicle, verify ownership, cut a new key from the VIN, and program it on-site — no tow, no dealer wait.
My CT 200h is push-to-start — can you program that outside the dealer?
Yes. Late models (2011–2017) use a proximity smart key on Texas Crypto 4D (4D68, DST80 “G”) — we carry the fobs and the programmer, and we cut the emergency blade.
