Frequently Asked Questions
What is a killer key?
A killer key, also called a lockout key or disabling key, is a pre-cut key designed to render a lock cylinder inoperable. When inserted into the matching keyway, it prevents the original key from turning the lock. It is a professional tool used to quickly secure a lock against unauthorized access.
Who uses these?
Locksmiths, property managers, landlords, building maintenance teams, and rental property owners. Common use cases include disabling a lock after a tenant moves out without returning keys, securing a property after a break-in attempt while waiting for a re-key, and emergency lockouts where immediate disabling is required before a full lock replacement.
Will the lock still work after using this?
No. That is the purpose of the tool. After a killer key has been used on a cylinder, the lock will need to be professionally re-keyed or replaced before it will operate again. Plan to schedule that work before using a killer key.
Will it fit my Kwikset lock?
It fits any KW1 5-pin keyway, which includes the majority of Kwikset, Weiser, Titan, Atlas, and Dexter residential locks. It will not fit Schlage (SC1, SC4), Yale, Master, or other non-Kwikset keyways. Confirm your lock uses the KW1 keyway before purchase.
Is this Made in USA?
Yes. The "USA" stamp on each bow confirms domestic manufacture. Higher quality control standards than imported lockout keys, with a clean cut pattern that consistently disables KW1 cylinders.
Is this legal?
Yes, killer keys are legal locksmith tools sold openly. However, the buyer is responsible for lawful use. Using a killer key on a lock you do not own or are not authorized to disable may violate trespassing, vandalism, or property damage laws depending on your jurisdiction. By purchasing, you confirm you intend to use the tool lawfully.
How fast do you ship?
Fast shipping is a priority. Same-day shipping on orders placed before noon local time, next business day otherwise. Free USPS Ground Advantage shipping with tracking included on every order.
Do you accept returns?
No. All sales are final. Due to the specialty nature of this professional locksmith tool and chain-of-custody considerations for lockout devices, returns are not accepted. Please verify compatibility and review the product carefully before purchasing.
