I know it's close, if I remove the battery of my main key the car still flashes the key indicator. How far does it detect the key?
3ft (1m) (see p.44 of Destruction Manual) (…they're talking about disabling the entry function to prevent the batteries running down, and then they go on to say don't leave the key within 6ft (2m) of the vehicle if it is not to be used for an extended period of time (to help prevent theft) - Good Luck!!! - hope this helps - Wil PS: Check under the seats, in the secret compartment under the armrest, in the glove boxes, down the sides or back of the seats…
I think you're talking about that red key that flashes on the dashboard. That's not telling you that it's detecting the presence of a key fob. It's telling you that the "security system" is on. (I put security system in quotes because it's not really a security system. It's the ignition lock if I remember correctly)
I think if it was inside, the car'd be freaking out everytime you go to lock it. I lost track of one fob for a day or two. When I finally found it I put luggage tags on both fobs with phone number and email. Also taped the same info on the locking lug nut socket.
I still haven't any luck. I'm looking for a replacement. I found an exact model version on ebay: Toyota Prius Smart KEY Keyless Entry Remote FOB | eBay But I called Toyota and they say it must have been used in a Prius with the same production batch, so that the computer is the same. Should I try the one on ebay ? A new one is soo pricey (320 CAD$). I found numerous posts on PriusChat about programming a key ourself. I'm fine with VirtualBox and any software preparation I would need to do, but I still have not find a procedure from A to Z, it's not complete here: I found that I can buy a brand new key: TRANSMITTER for 2010 Toyota Prius|89904-47150 That's the first step. I'm still willing to try the used key.
Kensiko I've done this so remember: IMPORTANT NOTE: Always get new/used fobs that match the FCC ID code to be added to your car. Link to more info click here.
