Can a Spare Key Start a Car?

[OSienna]

Here is some relevant information about spare keys: 1. First, there is usually a mechanical key hidden inside our remote key, so let's find it first. After locating the mechanical key, since manufacturers now generally conceal the door keyhole for aesthetic reasons, you need to pry open the outer shell from the car handle to find the keyhole inside. 2. If the vehicle is equipped with a one-button start function, the manufacturer has designed a sensing area for this scenario. Simply place the key in the sensing area and then press the start button to start the car. However, the location of the sensing area varies widely among different models—some are directly near the start button; some are under the steering wheel; others are inside the center console... If you're unsure where the sensing area is, it's best to refer to the vehicle's user manual. 3. Generally, a spare key can start the vehicle. For models with one-button start, the method to start the car is the same as the second method described above. However, some car owners have reported that their spare key could only unlock the door but not start the vehicle. This is because the spare key lacks an anti-theft chip, preventing the car from recognizing the key and triggering an alarm.
