The most common reasons a 2012 Subaru Forester key won't turn are a binding steering column/lock, an ignition switch issue, or a problem with the ignition key.
  • Binding Steering Column/Lock: A binding steering column or lock can occur due to a worn or damaged steering column assembly or issues with the ignition lock mechanism.
  • Ignition Switch: A faulty ignition switch can prevent the engine from starting or cause intermittent electrical issues, affecting the vehicle's ability to run properly.
  • Ignition Key: A worn or damaged ignition key or ignition cylinder can prevent the key from turning, leading to starting issues.

What are the steps to diagnose why the key won't turn in a 2012 Subaru Forester?

To effectively diagnose why the key won't turn in your 2012 Subaru Forester, start with a systematic approach that prioritizes simpler solutions before delving into more complex issues. Begin by checking the battery and electrical system, as a weak battery can hinder the ignition and shift mechanisms. If the battery appears to be in good condition, inspect the shift mechanism, particularly the tab on the shifter guide plate, which can become bent and prevent proper contact. Next, confirm that the transmission is securely in the PARK position; if the dashboard indicates it is, yet the key remains unresponsive, the gear selector switch or ignition switch may be at fault. Additionally, examine the ignition switch and surrounding components for any misalignments or bends that could obstruct functionality. If these checks do not yield results, consider lubricating the ignition lock cylinder to alleviate any sticking issues. It's also crucial to rule out the immobilizer and VALET MODE, as these can prevent the key from turning. Lastly, ensure the steering wheel is not locked, as this can sometimes create the illusion of a key issue. If all else fails, consulting a professional mechanic or Subaru dealership may be necessary for a thorough diagnosis and repair. By following this structured diagnostic approach, you can efficiently identify and potentially resolve the issue with your ignition key.

What are the common problems that could cause the key to not turn in a 2012 Subaru Forester?

When dealing with a key that won't turn in a 2012 Subaru Forester, it's essential to understand the common problems that could be at play. One frequent issue is the steering wheel lock engaging, which can create pressure on the ignition cylinder. To alleviate this, try moving the steering wheel back and forth while attempting to turn the key. Additionally, the key or ignition cylinder may be worn out; if the key fits but doesn't turn, consider trying a new key or applying lubricant to the ignition cylinder. Electrical problems can also be a factor, so check if other components, like hazard lights, are functioning, as a blown fuse could be the culprit. Furthermore, ensure that the gear selector is in the "PARK" position, as misalignment can prevent the key from turning. Lastly, if the ignition lock cylinder mechanism is faulty, lubricating it might help, but more severe issues could require replacement. By systematically addressing these common problems, you can often resolve the key turning issue effectively.

What should I do if the key won't turn in my 2012 Subaru Forester?

If you find that the key won't turn in your 2012 Subaru Forester, it's crucial to address the issue promptly to avoid potential safety risks or further damage to your vehicle. One of the first things to check is whether the steering wheel lock has engaged, which can put pressure on the ignition cylinder. By firmly gripping and wiggling the steering wheel, you may be able to relieve this pressure and allow the key to turn. Additionally, inspect the key itself for any signs of wear or damage, as a faulty key can prevent ignition. If the key appears to be in good condition, consider applying a small amount of lubricant to the ignition lock cylinder, as a sticky mechanism can hinder the key's movement. It's also important to ensure that your vehicle is in the correct gear, particularly if you have an automatic transmission, as being out of 'Park' can prevent the key from turning. Lastly, check for any electrical issues, such as blown fuses, which could indicate a deeper problem. If these steps do not resolve the issue, seeking professional assistance is advisable to prevent further complications. Addressing these symptoms early can save you from more significant repairs down the line and ensure your vehicle remains safe and operational.
