If you’ve ever tried to order replacement keys for your tool box, you’ve probably run into one frustrating issue: key code confusion. Customers often aren’t sure which code matters, which key blank to choose, or why similar-looking codes don’t always mean the same thing.
Let’s break this down in a clear, practical way so you can confidently identify the correct replacement key for your tool box.
Two Main Types of Tool Box Lock Systems
When it comes to brands like Craftsman, Husky, Kobalt, Mac Tools, and Waterloo, most locks fall into two general categories:
1. Newer Model Locks (Modern Key Systems)
These are commonly found on newer tool boxes and typically use:
- Key Codes: 8000 – 8223
- Key Blank: Ilco 1605
These locks are more standardized across brands, meaning multiple manufacturers share the same code series and key blank. If your tool box is relatively new, this is likely the system you’re dealing with.
👉 Key takeaway: If your code falls between 8000–8223, and are newer you’ll almost always need an Ilco 1605 key blank.
2. Older Model Locks (Legacy Key Systems)
Older tool boxes from Mac Tools, Craftsman, and Waterloo may still use similar code ranges—but require a different key blank.
- Key Codes: Often still in the 8000 range
- Key Blank: Ilco 752
This is where many customers get confused. Even though the code looks the same, the key blank is different because the lock design is older.
👉 Key takeaway: Same code range doesn’t always mean the same key—lock age matters.
Understanding Expanded Code Variations
To make things more confusing, you may also encounter variations like:
- 8001 – 9000
- A8001 – A9000
- 8001A – 9000A
- Z8001 – Z9000
Here’s the important part:
👉 Even though these codes look different, the actual key cut is identical.
Why Customers Get Confused
Most confusion comes down to three things:
- Same code, different key blank (modern vs. older locks)
- Different code formats, same key cut (letter prefixes/suffixes)
- Multiple brands sharing identical systems
Because brands like Husky and Kobalt often use the same lock suppliers, the overlap in codes is very common.
How to Choose the Right Replacement Key
Before ordering, check:
- Your key code (usually stamped on the lock face)
- Approximate age of the tool box
- Brand (for reference, not final decision)
Simple Rule of Thumb:
- Newer box → Ilco 1605
- Older box → Ilco 752
Final Thoughts
Tool box key replacement doesn’t have to be complicated, but understanding the difference between lock generations and key blanks is critical.
The biggest mistake customers make is assuming that the code alone determines the key—when in reality, the lock type and age are just as important.
By identifying whether your box uses a modern or legacy system, you can avoid ordering the wrong key and get back to work faster.
