FOB starts 2008 but will not lock or unlock doors

this car lost it's auxilary battery and sat for some months. when I put in new battery the alarm was triggered and i couldn't figure anyway to shut it off. again, maybe the red button on the remote is also not responsive. don't know if those functions are independent of some RFD tag that allows the car to start when it is inserted in the dash.

i changed the battery in the remote but no discernable difference. the old one was showing 3 volts anyway and my understanding is it should be 10% low to really be dead.

people talk about buttons and the smart system. there is a button that says key facing out beneath the dash and steering wheel. i had read you could do a reset by pressing that button and then holdoing the start button for 30 seconds. nothing seemed to happen when i did that. the car powered up while i was holding the button in. so i kinda ran out of things to try or pieces of knowledge from various threads that popped up.

also, when the car is off, it is flashing the so-called immobilizer inidcator (red car icon with key inside). i don't recall this being a constant condition before, but maybe i just did not notice.

thanks for any ideas from here.

didn't realize it had an in and out state because it operates like a momentary press, but now i see you are correct. what is the purpose of in or does some kind of reset require it to be left in the in mode, or left in the in mode for 10 or 20 seconds and then pressed again to return to the out mode?

 

not sure if this is an OEM FOB. There is no emblem. Car had 200,000 when i got it and the FOB had been beat up although it could have been generic replacement. It allows the car to start when in the slot. There is a small LED but I don't believe i've seen it blink. Is the an owners manual section on prius chat where i could look at this? Thanks

 

thanks. things i wish i knew before. . . so maybe that would turn off that flashing immobilizer symbol as well. i was wondering about battery consumption for all this standby stuff.

 

And would this explain if its possible to have a FOB that starts the car but isn't recognized by the security system or locks? Not sure if it is possible for the slot to be programmed to the remote without those auxiliary systems being included. Thanks
