ASX key problems we can help assess
A useful example is a second key is wanted for a shared car. The symptom tells us which checks should come before replacement.
No usable key remains
Losing every ASX key is a bigger job than a spare, but often still possible at the car. The year tells us which route applies.
Key not detected
Before any new key is suggested for a ASX, we check whether the fault sits in the key itself or in how the car is detecting it.
Broken blade or shell
If the chip inside still works, a damaged ASX key may only need a new shell.
