FAQs
Can I cut this key myself at home?
It is not recommended unless you possess a professional-grade key-cutting machine and the necessary technical expertise.
How do I know if my lock uses a K1 key?
Check your original key for a stamp identifying the profile as K1 or consult the packaging/documentation provided with your Master Lock product.
Does this product come pre-cut?
No, this is a key blank. It is a solid metal piece that must be cut by a locksmith or key-cutting service to match your specific lock.
Will this key work on other brands of padlocks?
No, the K1 profile is specifically designed for compatible Master Lock security devices and will not fit locks with different keyway profiles.
How long should a key blank last?
When cut correctly and used with a properly maintained lock, the key should provide years of reliable service before showing signs of metal fatigue.
Troubleshooting
Key does not slide into the padlock smoothly
Check for burrs or jagged edges left over from the cutting process and have the key lightly deburred.
The key inserts but will not rotate the cylinder
Verify that the bitting pattern was copied correctly from the master key or try lubricating the internal lock mechanism with dry graphite.

Setup, Compatibility & Care
To ensure success, verify that your existing padlock is compatible with the K1 key profile before purchasing. This product is a 'blank' and is not pre-cut; do not attempt to force an uncut key into a lock. For care, keep the key clean and free of debris. If the key becomes difficult to turn, apply a light, dry lubricant like graphite spray into the padlock's keyway rather than using oil-based lubricants, which can attract dirt and cause jamming. Store spare keys in a secure, designated location away from the lock itself.
