[OAlexander]

Installing a one-button start system for the Excelle at a 4S dealership is not safe and poses certain security risks. The reason is that modifying the one-button start system may damage the original vehicle wiring, leading to the malfunction of some vehicle functions. Functions of the one-button start system: 1. Automatic unlocking; 2. Automatic locking; 3. Automatic window closing; 4. Automatic anti-theft; 5. One-button start; 6. One-button shutdown. The method to use the one-button start system: 1. Open the car door and sit inside; 2. Press the brake pedal; 3. Press the start button to complete the one-button start. The working principle of the one-button start system: It uses radio frequency identification technology, automatically unlocking the door through the chip in the smart card. When the owner approaches the vehicle, the car automatically recognizes the owner's identity, and the door locks will open automatically while disabling the anti-theft system, eliminating the need for a key.
