How to Open the Car Door When the Battery is Dead?

[McBrielle]

When the car battery is dead, the method to open the door is as follows: The key usually comes as a folding key or a smart key with a chip. For a folding key, simply insert it to open the door. For a chip key, locate the mechanical part; the main body contains a safety mechanism that can be directly opened to reveal it. More information about smart keys is provided below: 1. A car smart key can emit infrared signals, which can open one or two doors, the trunk, and the fuel filler cap, as well as operate the car's windows and sunroof. 2. More advanced smart keys resemble a credit card. When the driver touches the door handle, the central locking control system activates and emits a wireless query signal. After the smart key card responds correctly, the car lock automatically opens.
