Can You Drive with a Spare Key?

[DeFelicity]

Whether you can drive with a spare key depends on the configuration of the spare key. If the spare key also has a remote control function, you can drive the car. If the spare key does not have a remote control and the car is in an anti-theft setting state, you cannot drive the car because the anti-theft system will consider the spare key as a master key and refuse to start, triggering an alarm—this is the anti-theft feature. Most car main keys are remote-controlled, while spare keys are mechanical. A remote key allows you to unlock and lock the doors from a distance, whereas a mechanical key is just a regular key that cannot perform these functions remotely. In comparison, the spare key is less convenient than the main key.
