Can the car start with one button if the key is not present?

If the car key is not present, it cannot start with one button. The remote key usually contains a hidden mechanical key inside. First, find the key and locate the mechanical key, then find the hidden keyhole on the exterior of the car to open the door. Generally, vehicles with one-button start are designed with a sensing area. As long as the key is placed in the sensing area, pressing the start button will initiate the car. The one-button start is a component installed in smart cars, serving as a button device to simplify the ignition process and also to turn off the engine. The one-button start can be retrofitted either at the original key lock position or as an independent panel modification.
I've been driving for several years and have tried various push-to-start functions. To be honest, the car simply won't start without the key inside or within detection range. The system relies on wireless signals to detect the key. If the key is just a few steps away from the car—like forgotten at home or left in a pocket—pressing the start button won't get the engine to budge. I once experienced this when I left my key on the office desk. I kept pressing the button in the car with no response, wasting half an hour before realizing the issue. From a safety perspective, this design prevents theft or accidental starts, so it's important to develop a habit of keeping the key in your pocket or a designated spot. A depleted key battery can also cause detection failure, so I regularly replace the battery and keep a mechanical key as backup. Overall, push-to-start is convenient and cool, but only if the key is nearby and doesn't wander off.
As an ordinary driver, I commute by car every day. The one-button start feature is very convenient, but it only works when the key is inside the car. When the key is not present, pressing the button results in no response from the car at all. Once, I got out to buy something with the key in my pocket, and when I returned to the car, the start failed, reminding me of the issue. The lesson is to always carry the key with me to avoid trouble. The detection range is limited, generally effective only near the car door. Regarding the battery, the system becomes unstable when the battery is low, so it's advisable to have a spare key as a backup. The security design is excellent, with strong anti-theft features. Developing the habit of checking the key's position before getting in the car can prevent unnecessary delays. These details make driving life smoother.
