I just wonder why lock by fob and we pull handle on the driver side and front passenger can open the door ? It is default system or error ?
if i understand you correctly, it may be programming you can change yourself. check your owners manual.
The doors can be programmed to unlock in various ways. That is why Bisco suggested you consult the owner's manual. It appears to me that your car's programming has been adjusted whereas all the doors will unlock, which is a feature that Prius offers. Again, consult your owner's manual for more information. Here is the info that is online at Toyota's website. Refer to page #31 for the details on how the doors can be programmed. http://www.toyota.com/t3Portal/document/om/OM47509U/pdf/2-1.pdf Ron
