Problem overview

Some Chevrolet S10 owners report experiencing ignition issues due to incorrect key cuts, which can lead to non-functional keys. Key tip wear is a common problem, where the tip of the key may wear off, causing misalignment of the pins and resulting in difficulty turning or removing the key. Additionally, owners are advised to have keys cut by code rather than simply copied, as copying a worn key can reproduce the same issues and potentially damage the lock cylinder, causing it to jam. A worn ignition cylinder is another factor that can lead to keys getting stuck, making it hard to turn or remove them. Furthermore, misalignment of the steering wheel when turning off the engine can also contribute to the key getting stuck in the ignition. To prevent these issues, it is essential for owners to ensure proper key cutting, maintain the ignition cylinder, and align the steering wheel correctly when parking. Regular maintenance and using the correct key can help mitigate ignition problems associated with incorrect key cuts in a Chevrolet S10.
