Featuring a Limited Lifetime Guarantee, Defiant offers a Tonebridge Lever Combo Pack with proven durability and security. The design provides easy installation with only a Phillips screwdriver. The finish gives a clean look with a modern feel to your home. This combo set is most effective for exterior doors where keyed entry and security is needed. Defiant keyed locks can be re-keyed to fit your existing KW1 keyway. Please speak with an associate at your local Home Depot for further assistance with this process.
