Can a Spare Car Key Start the Vehicle?

[LeArcher]

Yes, a spare car key can start the vehicle. Here is some relevant information about spare keys: 1. Each car is typically equipped with two keys—a primary key and a spare key. Although there is a distinction between primary and spare, both keys function the same way and can start the vehicle. 2. For push-to-start models, simply place the key in the designated induction area and then press the start button to ignite the engine. However, the location of the induction area varies across different car models—some are directly near the start button, some are under the steering wheel, and others are inside the center console. In some cases, the spare key may only unlock the doors but not start the vehicle. This happens when the spare key lacks an anti-theft chip, preventing the car from recognizing the key and triggering an alarm.
