What to Do When the Car One-Button Start Battery Dies?

[MacAngelina]

When the car's one-button start battery is dead, you can insert the smart key into the dedicated key slot. The car will detect the key and allow you to start the vehicle. The one-button start device is part of a smart car, serving as a button mechanism to simplify the starting process and also to turn off the engine. This device can be retrofitted either in the original key lock position or on an independent panel. Key considerations for installing a car one-button start system include: 1. When connecting the plug wires, note that the ignition switch has three common positions besides OFF: ACC, ON, and START. During installation, first determine which wire or wires are connected under each position using a test pen or multimeter. After identifying them, mark the wires and connect them to the corresponding ACC, ON, and START output connectors of the keyless start system. 2. The button can be installed on the panel or inside the original keyhole, depending on the owner's preference. 3. For the steering lock, consider replacing the key blade with a new one.
