How to Open a Car Door with a Spare Key?

[LeAngelina]

To use a spare key, you need to insert it directly into the door's keyhole to unlock the door. The spare key does not have a remote control. It is used when the primary key is lost. Here is some relevant information: 1. The vast majority of vehicles come with two keys, one primary and one spare. Some cars also have a dedicated repair key, which is given to technicians for test drives during repairs. Some high-end vehicles have spare keys with remote controls. The remote key contains a battery, which needs to be replaced when it runs out of power. 2. When using the remote key, avoid unlocking or locking the car from a long distance, as this can accelerate battery drain. Once the battery is dead, it must be replaced immediately. Some cars are equipped with a push-button start system, and vehicles with this system do not have a keyhole inside the car.
