Prior art shortcoming:
1) shortcoming one: if push down battery case by thimble, due to reasons such as vibration or switch jaw contact, is easy to cause bad contact, causes remote controller normally to work, also just can not start vehicle.
2) shortcoming two: if directly use electric soldering iron welding lead on a remote control, easily causes electrostatic damage remote controller and the problem such as not easy to operate.
3) shortcoming three: because whole verification process is all wireless mode, no matter be the low frequency wake-up signal of 125KHz or 134.2KHz of low frequency or the UHF acknowledge signal of 434MHz, capital is subject to external interference, and cause normally by certification, thus causing remote control to start the inefficacy controlled.
