Frequently Asked Questions
Why is the Immobilizer / Key Light on in my Chery Tiggo 4?
Your Chery Tiggo 4 turned on the Immobilizer / Key Light after its self-diagnostics flagged an issue in that system. Because several different faults can trigger the same symbol, the smart first move is an OBD-II scan to pull the specific code before you spend any money.
Can I keep driving with the Immobilizer / Key Light on?
Short answer: sometimes, but not indefinitely. Given this indicator's moderate priority, respect the warning colour and the car's behaviour. When in doubt with your Chery Tiggo 4, the safe choice is to stop and have it checked rather than risk further damage.
How much does it cost to fix the Immobilizer / Key Light on a Chery Tiggo 4?
There is no single price for the Immobilizer / Key Light on a Chery Tiggo 4; it ranges from a no-cost adjustment to a component replacement. The honest way to control cost is to diagnose the exact code before authorising any repair, so you only pay to fix what is actually wrong.
Will the Immobilizer / Key Light reset itself on a Chery Tiggo 4?
Sometimes the Immobilizer / Key Light on a Chery Tiggo 4 clears on its own once the condition that triggered it no longer exists — for example after several good drive cycles. More often, though, the light stays on until the underlying fault is repaired and the code is cleared, so treat a self-clearing light as a reason to still investigate.
