Keys not working
#61
I am trying to read the owner’s manual as regards the Customizable Features. It seems that the instructions are somewhat different depending on whether it has the Nav Sys or not. I’ll look at it some more.

Try this reset procedure.
Get out of the vehicle.
Lock the car with the emergency key on the driver’s door.
Leave the vehicle parked for at least 5 minutes.Walk away 20ft minimum with fob.
Press unlock on the key-fob to unlock the car. Don’t open any doors yet.
Remove the emergency key from the key fob and lock/unlock the driver’s door three times.
Now enter the vehicle and start the engine. press the start button with your key-fob, not your finger.

Oh yeah. If the fob wont unlock the doors then try this relearn procedure..
You need a paper clip small one. Bend it in a U shape about 1/4 inch or so wide.
Look for your OBD port under dash and insert clip into pins 4 and 13. Pin 4 is on top row from left to right.
Pin 13 is straight down next row and over one to the right.
Push start button to on position but don't touch brake pedal.
Leave this on for 30 minutes with fob in vehicle and then shut off. Remove paper clip.
Start car and all should work again.

Pins 4 and 13 are for determining transmission fluid temp when TS isn't available so you will know when to check the fluid level so it's a self diagnostic function, I've read here that some people use it for initializing electric parking brakes and now for initializing key fobs.
That may be possible but when using it for trans temp there is a little procedure before it will go into that mode...I doubt you can just plug a jumper in and it will decide what you need to get done.

HI Gerf I never knew there were other uses for that jumper as you mentioned. I had only heard of getting fobs and transponder keys to work again.
Good to know. This also works on Toyota's as well. A friend has a 2013 Avalon and he replaced the cars battery and for some reason his fobs wouldn't work afterwards and this method got his working again. What I don't understand is why this happens to some and not to others?
Ive had Toyota's for years and luckily I guess have never had it happen to me.
And I don't know if its risky. I was there when we did this on the Avalon and nothing bad happened and it cured the problem.
I do wonder what exactly is going on during that 30 minute time. Maybe someone here knows?

Getting away from discussions, going to a locksmith, paying for one reprogram and potentially doing the same yourself for the second key is most likely to resolve your issue. Personally, after 5 pages of suggestions and discussion, I'd just pay the fee and be done with this situation. But you're free to keep hoping for a free fix.
