What does 'Please use the backup starting slot' mean?

It means the car cannot detect the key. Here is some information about car keys: 1. Introduction: A car key is a tool used to start the car. Modern car keys use a chip, which is part of a magnetic chip system. 2. Principle: The reading coil in the car's ignition lock cylinder reads the chip in the key; each chip has fixed digital information. 3. Types: A remote key allows you to lock and unlock the car from a distance without inserting the key into the lock. Its biggest advantage is that, regardless of day or night, you can conveniently lock and unlock the car from a distance without needing to locate the keyhole.
After all these years in auto repair, I can tell you the backup start slot is typically an emergency feature in certain vehicle designs, primarily used to start the engine when the primary ignition system fails—like when the key fob battery dies or a sensor malfunctions. Simply put, it's a physical slot where inserting a backup key or start tool directly engages the starter motor. Not all cars have this, but it's more common in newer models, especially German brands, with the manual specifying its location (e.g., near the steering column). Technically, it bypasses the primary system’s complex controls via direct circuitry. For maintenance, regularly check for dirt or oxidation in the slot and clean it with a soft cloth. I’ve seen clients panic in emergencies due to neglecting this feature, so familiarizing yourself with your car’s equipment beforehand is crucial. Side note: Hybrid models may lack a standard slot, using a backup button instead.
