You don't need to buy a new one. A new latch unit costs around $450. Ouch! You could buy the plastic connecting piece where the dented round notch is for $11 at the Lexus dealer. And if the other end broke at the round hook, then you could use a metal wire and wrap around this rod and also create a circle so it could hook to the door latch when the latch moves up and down. Basically, you create the similar shape like the new rod.
