1. Try Extraction First:
* Specialized Key Extractor Tool: Auto parts stores and locksmiths sell small tools designed to grip and remove broken key pieces from locks. This is your best bet for minimal damage. Attempt this *carefully* to avoid pushing any fragments further into the mechanism.
* Needle-Nose Pliers (Careful!): As a last resort, *very carefully* use fine-needle nose pliers to grip the broken key piece and pull it out. This is risky and can easily damage the lock cylinder.
2. If Extraction Fails, More Invasive Methods:
* Professional Locksmith: This is your best option to minimize damage and cost in the long run. A locksmith has specialized tools and expertise to open the trunk without causing significant harm. They might be able to extract the broken key or bypass the lock entirely.
* Internal Trunk Release (If Equipped): Some 1974 Catalinas might have an internal release lever or cable inside the car that can be accessed from the passenger compartment. Check your owner's manual (if you have one) or consult online resources for your specific model to see if this is possible.
* Accessing Through the Back Seat (If Possible): Some older cars have a pass-through to the trunk from the rear seat. Check if your Catalina has this feature. If it does, and you can access the trunk latch mechanism, you might be able to manipulate it open.
* Drilling the Lock (Destructive): This is a last resort and will require replacing the lock cylinder. It's generally not recommended unless all other options have failed, as it's the most damaging approach. A locksmith can do this cleanly, minimizing further damage.
Important Considerations:
* Damage to the Lock: Any attempt to open the trunk without the correct key will likely cause some damage to the lock mechanism. Be prepared for potential repair or replacement costs.
* Safety: Be cautious when working around the lock mechanism. Avoid applying excessive force, which could cause further damage or injury.
* Security: Once you gain access, consider replacing the lock cylinder to improve security.
Before attempting anything yourself, consider the cost and potential damage versus calling a locksmith. A locksmith will likely be the most efficient and cost-effective solution in the long run.
