Hi All I have replaced my car battery to Energiser instead of Panasonic. However, i notice that if i put the key inside my bag or pants pocket, it cant detect unless i hold the key and touch the door handle only can open... When i enter into the car, there is no key battery message appear. And i could press push start button without any problems. So i wonder what is possible issues?? Is it still because the car key battery or key or the car battery? Thanks.
