Key not detected

[ProfGlenn]

Hi.  Sometimes I can’t get in my car or when I do get in, the car won’t start because the key is not detected.  I have changed the key Battery and I think so did Toyota at Christmas.  It’s driving me nuts.  What else can I try?  Sometimes when stationary with ignition off the car locks itself as well although I think that’s a motion sensor issue.  

 

Thanks

"the car wont start because the key is not detected" - when this comes up, where do you have the key?  Do you have any other electronic keys near when the key cannot be identified?

Do you have the Auris Hybrid Owners Manual? That gives a lot of info how the key works efficiently, and lot of info why it may not work.

Have you tried holding the key onto the POWER (Start) button? Even a very low Battery holding near to the POWER button should activate.

You say you already put a new Battery in and you THINK Toyota did just before xmas as well.  Lets just forget the "thinking" bit, best to know what Toyota (or anyone else have done), but the Battery you put in - was it brand new or one thats been lying around for some time? 

Where do you store your key when back in the house?  Other electronic devices nearby can mean the battery is always active, thus wearing it out quickly. All in the Auris Hybrid owners handbook.

Thanks.  I put a brand new Battery in it and it was still doing it.  I don’t keep my keys near anything electrical.  It’s only the last few months it’s been getting worse and I have had the car 4 years.

Everything on the service in December was fine.

 

Thanks

Does the 2nd key act the same?
