“What do I do if my key broke?” This is a more common experience than you might imagine. A simple answer to this question is to replace the key or make use of your spare key if you have one. However, there’s a bit more to consider, so let’s dive into the details.

Is It Possible to Fix a Broken Key?

In most cases, no, it’s not possible to fix a broken key by simply putting the pieces back together. The simplest solution is to get a replacement key. At MiniFob and FobToronto, we can attempt to create a new copy using the broken pieces of your key, but we recommend considering a locksmith or contacting your building management instead. While our service is available, there are important factors to keep in mind if you choose us to “repair” (make a copy of) your broken key:

  • Reliability Concerns: A key copied from broken pieces may not be as reliable as the original. To create the copy, we’ll place the broken pieces in our key cutting machine (assuming you have all the pieces). The machine will trace the broken key, but since the original key is damaged, the tracing might not be 100% accurate. For a better understanding of this logic, you can check out our blog post, “How To Cut a Key“. 
  • How The Key Breaks Matters: The key needs to have broken in a specific way for us to attempt this. This is why we always recommend having spare keys on hand—if your key breaks, you can use the spare to create new copies. If your broken key can’t be “fixed” (recut) and you don’t have a spare, you’ll need to talk to your building management or call a locksmith.

Why Do Keys Get Stuck in Locks?

Understanding why keys get stuck in locks can help you prevent future breakages. Here are some common reasons:

  • Poor Lubrication: When a lock isn’t properly lubricated, its internal pins and springs can jam, making it difficult to turn the key and unlock the door.
  • Twisted or Damaged Key: A twisted, bent, or damaged key can cause the lock to jam by snapping inside it.
  • Lock Cylinder Issues: A defective or damaged lock cylinder can cause the lock to jam. This could be due to normal wear and tear, mechanical damage, or tampering. 
  • Frozen Lock: In colder climates, moisture can seep into the lock and freeze, making it difficult to move the key.
  • Build-Up of Dirt and Debris: Over time, dust, dirt, metal particles, and other debris can accumulate inside the lock, causing it to jam and stop working properly.

Why You Should Get a Spare Key

At MiniFob and FobToronto, we offer key cutting services that can help you avoid the inconvenience of a broken key in advance. We strongly recommend getting a spare key made before you actually need it. Don’t ignore the reasons we’ve listed above—taking action before your key gets stuck or breaks can save you a lot of trouble. So, what do I do if my key broke? The best course of action is to replace the key or use a spare if you have one. If you don’t have a spare, consider contacting a locksmith or your building management for a reliable replacement. Remember, at MiniFob and FobToronto, we can attempt to make a copy from broken pieces, but it’s not always a guaranteed solution. To avoid this situation in the future, be proactive: get a spare key and address any potential issues before they lead to a broken key. If you need assistance, we’re here to help with all your key cutting needs.
