When the key is inserted into the ignition, an inductive coil around the barrel reads the special digital code from the chip. If the code matches the one stored in the vehicle's Body Control Unit (BCU), the engine is permitted to start.
- Phase 1 (Fixed Code): Used in the late 90s, these keys had a fixed code. While safer than mechanical keys, they were vulnerable to being copied.
- Stage 2 (Rolling Code): Introduced in the early 2000s, this system produces a brand-new code whenever the key is utilized, making it nearly impossible for burglars to obstruct and reproduce the signal.

- Use Silicone Covers: Inexpensive silicone sleeves can secure the plastic real estate from effect damage if the secret is dropped.
- Oil Locks: If the crucial feels stiff in the door or ignition, utilize a graphite-based lubricant. Prevent oil-based lubes like WD-40, as they can bring in dirt and gunk up the tumblers.
- Keep a Spare: The most crucial upkeep idea is to always have a functional spare key. The expense of duplicating a working key is considerably lower than producing a new one from scratch when all keys are lost.
