Here's a breakdown of how to approach this problem, starting with the least invasive solutions:
1. Try these before replacing the lock:
* Graphite Lubricant: This is your first line of defense. Spray graphite lubricant (NOT WD-40; WD-40 will attract dirt and eventually gum up the works) generously into the keyhole. Let it sit for a few minutes to penetrate, then gently wiggle the key back and forth. Try turning it again. Sometimes, corrosion or dirt is the culprit.
* Different Key: If you have a spare key, try that. It might be a problem with the key itself, not the lock.
* Gentle Force (with caution): Apply very gentle, even pressure while turning the key. Avoid excessive force, as this could damage the lock further.
* Tap the Key: Gently tap the key with a small hammer (wrapped in cloth to avoid scratching). This can sometimes help dislodge a stuck key.
* Check for Obstructions: Carefully inspect the keyhole for any debris, broken key pieces, or foreign objects. Use compressed air or tweezers to remove any obstructions.
2. If the key is still stuck after trying the above:
If the key is firmly stuck and you suspect damage to the lock cylinder itself, you'll likely need professional help. Here's why attempting a DIY lock replacement might be more trouble than it's worth:
* Complexity: Replacing a car door lock is not a simple task. It often involves removing interior door panels, disconnecting linkages, and precise alignment. You risk causing further damage if you don't have the experience or the right tools.
* Security Concerns: Incorrect installation can compromise your vehicle's security.
* Getting the right parts: You'll need to find a replacement lock cylinder that's compatible with your specific Mustang's year and model. This requires knowing the exact part number.
3. Seeking professional help:
* Locksmith: A locksmith is your best bet. They have the specialized tools and expertise to remove the stuck key and, if necessary, replace the lock cylinder safely and correctly.
* Dealership: Your Ford dealership can also perform this repair, though it will likely be more expensive than a locksmith.
In summary: Avoid jumping straight to replacing the lock. Start with lubrication and careful attempts to remove the key. If all else fails, call a professional. Attempting a DIY lock replacement without the proper knowledge and tools can cause significant damage and unnecessary expense.
