Why can't the car start with one-button start in cold weather?

In cold weather, the reasons why a car with one-button start fails to start include a weak battery and low battery power in the remote key.

Weak battery:

Find another car to jump-start yours. Connect the positive terminal to the positive terminal and the negative terminal to the negative terminal using jumper cables. Connect the positive terminal first, then the negative terminal. When disconnecting, reverse the order: remove the negative terminal first, then the positive terminal. After connecting, press the one-button start to ignite the engine. Alternatively, use a portable jump starter by correctly connecting it to the battery's positive and negative terminals, then press the one-button start to ignite the engine.

Low battery power in the remote key:

Typically, after one or two years of use, the battery in the remote key will weaken. This can cause the car to fail to recognize the remote key, preventing the engine from starting. A quick solution is to place the remote key against the key感应区 while pressing the one-button start. However, in such cases, the remote key battery should be replaced as soon as possible.
