When using Autel IM608 for Volkswagen 5C/5D key programming, many users believe OEM keys are always the safest option. In reality, this is a common misunderstanding that can lead to hidden risks.
OEM keys come with a fixed, non-changeable ID. If you use Autel IM608 to program an OEM key through unofficial methods, the key may work perfectly at first. However, problems can appear later when the vehicle connects to ODIS at the dealership. The system will verify the key ID, and if it does not match the official records, it may cause errors or even lock the module.
On the other hand, aftermarket keys offer more flexibility. With IM608 Pro II, their IDs can be rewritten and adjusted during programming. This allows the key to better match the system requirements and reduces the risk of future issues.
The key point is simple: when using Autel IM608 Pro, don’t just focus on whether a key is OEM or aftermarket. What really matters is whether the key data can pass system verification in the long run.
