How to Start with a Spare Key?

[SkylarLynn]

For vehicles with a one-button start function, simply place the spare key in the induction area to start the car. If this feature is not available, you can use the spare key to start the ignition directly. Below is some knowledge about spare keys: 1. Alarm: Some car owners have experienced that the spare key can only unlock the door but not start the vehicle. This is because the spare key lacks an anti-theft chip, causing the car to fail to recognize the key and trigger an alarm. 2. Battery Replacement: The method for replacing the battery in a car key is generally similar. Most remote keys come with a mechanical key, and some keys have the mechanical part folded or hidden. If it's a folding type, after extending the mechanical key, you can see the buckle from the folding position. Use a tool to press the buckle, and you can then remove the outer shell.
