Shift Interlock Mechanism:
- The shift interlock mechanism ensures that the vehicle is in Park before the key can be removed. If this mechanism is faulty or misaligned, it can cause issues with shifting gears and releasing the key. Check if there's any obstruction or damage to the mechanism.
Shifter Cable or Linkage:
- The shifter cable or linkage is responsible for transmitting the movement of the shifter to the transmission. If this cable or linkage is damaged, stretched, or misadjusted, it can affect the proper functioning of the shifter. Inspect the cable or linkage for any visible damage or disconnection.
Brake Switch:
- The brake switch is activated when you press the brake pedal. It signals the vehicle that you're applying the brakes, allowing you to shift gears and remove the key. If the brake switch is faulty or not properly adjusted, it can cause issues with shifting and releasing the key. Check if the brake lights turn on when you press the brake pedal.
Ignition Lock Cylinder:
- The ignition lock cylinder is located around the keyhole. If it's worn out, damaged, or misaligned, it can make it difficult to turn the key or remove it. Try inserting and turning the key multiple times to see if it helps.
Here's what you can try:
1. Double-check the gear selector position: Ensure that the shifter is fully engaged in the Park position. Sometimes, it's not pushed far enough, which can prevent the key from being released.
2. Inspect the shift knob installation: Make sure that the new shift knob is properly installed and aligned. If it's loose, crooked, or not seated correctly, it could affect the shifter's functionality.
3. Check the brake lights: Press the brake pedal and ensure that the brake lights illuminate as they should. If there's an issue with the brake lights or the brake switch, it can affect the shifter and key release.
4. Try turning the steering wheel: While holding the key in the "On" position, gently turn the steering wheel back and forth. Sometimes, the steering wheel lock can interfere with the shifter, so moving the steering wheel can help release the key.
5. Consult the owner's manual: Refer to your vehicle's owner's manual for specific instructions related to the shifter, gear selector, and key removal. There may be additional troubleshooting tips or procedures provided by the manufacturer.
If you've tried these steps and the issue persists, it's recommended that you take your car to a qualified mechanic or dealership for further diagnosis and repair. They can properly inspect the shifter mechanism, cables, and other components to identify the exact problem and provide the necessary solutions.
