Toyota gts 86 not searching for key
 

Hey guys I have run into a problem with my 86,
I was wondering if anyone could give me some ideas on what to try to fix it,
My 86 suddenly doesn't search for the key, nothing comes up on the dash when u try to start the car, I have checked all the fusses in the car but none were blown so I replaced the battery in the fob but that didn't work aswell.
Anyone have any ideas??
