- Inaccurate Key Copying: If the locksmith made a copy of the ignition key based on the old one without having the original key present, there could be deviations or imperfections that affect the accuracy and smoothness of the key's insertion.
- Worn Key Mechanism: The ignition switch and cylinder may be worn out or have accumulated dirt or debris over time. This can make it difficult for even the original key to fit and turn smoothly. The newly made key might encounter additional resistance or require more force to operate.
- Incorrect Cutting: During the key-making process, if the locksmith used the wrong key blank or made incorrect cuts on the key, it might not align precisely with the ignition's internal mechanisms, causing difficulties in insertion and turning.
- Different Key Type: There are various key types, such as standard, transponder, or laser-cut keys. If the original ignition key was a different type from the one made by the locksmith, it's possible that the replacement key is not suitable for your vehicle's ignition.
- Ignition System Issues: Independent of the new key, there might be underlying problems within the ignition system itself, like misaligned components, faulty wiring, or mechanical malfunctions. These issues could contribute to difficulties in inserting and starting the key, even with the original one.
In such cases, it's advisable to consult with a qualified automotive locksmith or a mechanic to diagnose the exact source of the problem. They can assess the new key's accuracy, inspect the ignition system for malfunctions, and provide appropriate solutions.
