The most common reasons a 2015 Subaru WRX 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 2015 Subaru WRX?

When diagnosing why the key won't turn in your 2015 Subaru WRX, it's essential to adopt a systematic approach that begins with the simplest solutions before progressing to more complex issues. Start by checking if the steering wheel lock is engaged, as this can prevent the key from turning. Firmly grasp the steering wheel and rock it back and forth to relieve any pressure on the ignition cylinder. Next, ensure that the transmission is in the correct position; for automatic vehicles, the gear should be in Park. If the key still won’t turn, examine the battery voltage, as a weak battery can disrupt electrical connections necessary for ignition. If the battery seems fine, try jiggling the key while turning it, as this can sometimes free up a stubborn ignition switch. Additionally, check the fuses and basic electrical systems to rule out broader electrical issues. If these steps do not resolve the problem, it may indicate a malfunction within the shift mechanism, which could require further inspection or adjustment. If all else fails, consulting a mechanic or a Subaru dealership for a professional diagnosis is advisable. By following this diagnostic approach, you can effectively identify and address the issue with your ignition.

What are the common problems that could cause the key to not turn in the ignition of a 2015 Subaru WRX?

When dealing with a 2015 Subaru WRX where the key won't turn in the ignition, it's essential to consider several common problems that could be at play. One frequent issue is the steering wheel lock, which can engage and apply pressure on the ignition cylinder. To alleviate this, try turning the steering wheel while gently attempting to turn the key, as this can help disengage the lock. Additionally, ensure that the brake pedal is pressed and that the transmission is correctly positioned; sometimes shifting the gear from park to neutral and back can release a stuck key. Another potential culprit is a malfunctioning neutral or park switch, which is designed to prevent the key from being removed unless the vehicle is in park. If these components are faulty, they may need replacement. Furthermore, wear and tear on the key or ignition cylinder itself can lead to sticking or failure to turn, necessitating a replacement of the ignition cylinder. Lastly, be aware that electrical issues can also interfere with the ignition system, and if the problem persists, consulting a professional may be necessary to diagnose any underlying electrical faults. By systematically checking these areas, you can often resolve the issue and get back on the road.

How urgent is it to address the issue of a key that won't turn in a 2015 Subaru WRX?

When faced with a key that won't turn in your 2015 Subaru WRX, it's crucial to recognize the urgency of the situation. Ignoring this problem can lead to more severe consequences, such as the key breaking off in the ignition or the vehicle becoming inoperable at a critical moment. If you find yourself in immediate need of your vehicle, there are some temporary solutions you can try, such as jiggling the steering wheel while turning the key or ensuring the vehicle is in the correct gear. However, if this issue recurs, it may indicate deeper mechanical problems, such as misalignment or wear in the ignition lock cylinder, which could necessitate professional repair. Addressing the underlying cause promptly not only enhances your vehicle's long-term reliability but also ensures your safety on the road. Therefore, while DIY fixes can provide a short-term solution, it is advisable to seek a thorough diagnosis from a trusted mechanic to prevent future complications and maintain the integrity of your ignition system.
