How to Start the Engine with a Key in a Push-Button Start System?

Method to start the engine with a key in a push-button start system: First, press the start button once to turn on the ACC light, then press the start button again. At this point, the push-button start will turn green, and the vehicle will begin self-checking. After the vehicle completes the self-check, press the brake pedal and press the push-button start once more to start the engine. Push-button start differs from traditional mechanical key ignition and conventional starting procedures—simply pressing the button starts or stops the engine, eliminating the hassle of lost or misplaced keys. Most push-button start systems require pressing the brake pedal during ignition. The push-button start is a part of smart car technology, serving as a simplified ignition button that also allows for engine shutdown. This system can be retrofitted in place of the original key slot or installed as an independent panel.

In the keyless start models I've driven before, you normally don't need to take out the key—just keep it in your pocket, press the brake, and hit the start button. But when you're unlucky enough to encounter a dead key fob, you'll have to resort to the emergency start procedure. Some cars hide a backup keyhole under the steering column; you'll need to pry off the plastic cover, insert the mechanical key, turn it halfway, and immediately press the start button for it to work. Other cars are even more extreme—just press the dead key fob directly against the start button, and once the system detects it, the car will start. However, these operations require precise timing; inserting the key too late or pressing the button too early won't work. If it's your first time dealing with this, it's best to have the dealership walk you through it to save hassle.
