What must be true for a vehicle with a remote starter to start using the RS remote?

For a vehicle equipped with a remote starter to operate correctly using the remote control, it is essential that the key is placed in the key cylinder. This requirement is standard for many remote start systems, particularly those that are designed to prevent unauthorized use or tampering. The inclusion of the key in the ignition cylinder essentially functions as an anti-theft feature, allowing the remote starter to activate the engine only when it detects the presence of the key.

This ensures that even though the engine can be started remotely, the vehicle remains secure and is not operable without the physical key present in the ignition system. This design helps to minimize the risk of theft because if someone attempts to start the vehicle without the key being in the cylinder, the remote start would not be authorized.

Other options suggest alternative scenarios, but they do not align with the operational requirements of most remote starter systems. For example, turning the key, removing it from the ignition, or having it out of range are not typical conditions that would allow for the safe and authorized operation of the remote start feature.
