First, maintain composure and avoid forcing it further. Inspect the key to see if enough material remains exposed for extraction. Use pliers or tweezers to grasp and gently pull out the broken piece if possible. Lubricate the keyhole with a graphite-based spray to aid removal. If self-removal proves challenging or risks damaging the lock, seek a professional locksmith's assistance. They possess the necessary tools and expertise to extract the key without causing damage.

The cost-effectiveness of fixing or replacing a door lock depends on the severity of the issue. Repairing a minor problem, such as loose screws or a need for lubrication, is usually cheaper than replacing the entire lock. However, replacing the lock if it is severely damaged, outdated, or lacks security features may be a better long-term investment. New locks often have improved security features, enhancing your property's safety.

A deadbolt lock is typically considered more secure than a regular lock based on its internal construction. Each deadbolt type has varying levels of security, ranging from withstanding a small amount of force to those that can take on multiple strikes and greater force. Regular locks provide little to no security and are typically used more for easy entry and simple installation.

If part of the key is protruding out of the lock, you can use a pair of needle-nosed pliers or tweezers to gently turn the key in the lock to open the door. If the key is fully inserted into the lock, you may also be able to use a key extractor to help turn the key into the unlocked position. 

But if the key breaks off halfway into the lock or you simply can’t reach it to help engage the unlocking mechanisms, you should probably call a professional.
