Doors And Ignition Prob

[Bobbie1]

I've just bought an 06 Prius T3 and its great but sometimes when i try and start it the dashboard lights up like a xmas tree with all the warning lights on, the key fob cannot be removed, eventually after a few minutes and several attempts at starting it turns the engine on, also the rear doors are not opening with the keyfob and sometimes the front doors dont open either?? is it something to do with the keyfob Battery? any suggestions very welcome. Many thanks.

Check the 12V Aux Battery.

From the symptoms given I also think your 12V Battery needs changing.

If the OP has just bought it, it might just want charging or a good run. Having said that, if it's the original 12v then at 6 years old it may be ready for replacing anyway.
