2015 Subaru Impreza Key Won't Turn

When diagnosing why the key won't turn in your 2015 Subaru Impreza, it's essential to start with the simplest solutions before moving on to more complex issues. Begin by checking the battery voltage, as a weak battery can prevent the ignition system from functioning correctly. Use a multimeter to ensure the battery is charged adequately. If the battery is fine, try jiggling the shifter to confirm that the vehicle is indeed in park, as the ignition system requires this to release the key. If the key remains stuck, inspect the shift mechanism by removing the shift boot to access internal components. Look for any signs of wear or misalignment in the shifter plate guide, as these can impede the key's release. Additionally, rocking the steering wheel while attempting to turn the key can sometimes help if the steering lock is engaged. If these steps do not resolve the issue, consult any relevant technical service bulletins for your vehicle, as they may provide insights into known problems and solutions. Finally, if all else fails, seeking a professional diagnosis from a Subaru dealership may be necessary to address more intricate mechanical issues. By following this diagnostic approach, you can systematically identify and potentially resolve the problem with your ignition key.

When dealing with a 2015 Subaru Impreza where the key won't turn in the ignition, it's essential to understand the common problems that could be at play. One frequent issue is the engagement of the steering wheel lock, which can inadvertently prevent the key from turning. If you find yourself in this situation, try gently moving the steering wheel back and forth while attempting to turn the key, as this can relieve pressure on the ignition cylinder. Another potential culprit is low battery voltage; a weak or old battery may not provide sufficient power for the ignition system to recognize that the vehicle is in park, especially in colder weather. Ensuring your battery is fully charged or replacing it can often resolve this issue. Additionally, problems with the shift mechanism, such as a bent plate or misaligned nubbin, can hinder the car's ability to recognize its gear position, thus keeping the key stuck. Inspecting and adjusting these components may be necessary. Furthermore, issues with the brake switch or shifter plate guide can also lead to similar problems, so checking for wear or incorrect installation is advisable. Lastly, if the key lock is still activated or there are issues with the ignition cylinder itself, moving the shifter through different positions may help. If these steps do not resolve the issue, it may be time to consider replacing the ignition cylinder. By systematically addressing these common problems, you can effectively troubleshoot and potentially fix the key turning issue in your Subaru Impreza.

Addressing the ignition issue in your 2015 Subaru Impreza when the key won't turn is crucial for several reasons. First and foremost, a stuck key can compromise your vehicle's security, preventing you from locking it and leaving it unattended, which poses a significant safety risk. Additionally, ignoring this problem can lead to more severe mechanical issues, such as a weak battery or a malfunctioning shift mechanism, which could escalate into costly repairs if not handled promptly. While the vehicle may still be operable, the ignition problem can disrupt normal functions, forcing you to rely on unreliable workarounds that could leave you stranded. Furthermore, if your vehicle is nearing the end of its warranty, timely intervention could allow you to benefit from warranty coverage or manufacturer support, ultimately saving you money. Therefore, it is essential to address any ignition issues as soon as they arise to ensure the safety, security, and proper functioning of your Subaru Impreza.
