SENY Jimmy Proof Deadbolt Night Latch, Single & Double Cylinder Surface-Mounted Security Lock for Front Doors

Why Customers Love It

Jimmy Proof Deadbolt Night Latch for Entry Door Security

Add an extra layer of security to your entry door with the SENY Jimmy Proof Deadbolt Night Latch. Its surface-mounted design provides a strong locking point without requiring a traditional mortised deadbolt installation.

Available in Single Cylinder and Double Cylinder options, this lock is designed for residential entry doors, replacement projects, and supplemental door security.

Jimmy Proof Security Design

The interlocking lock body and strike help resist separation when the door is closed, creating a secure connection between the door and frame.

  • Surface-mounted security design
  • Interlocking lock and strike
  • Strong metal construction
  • Designed for residential entry doors

A practical choice for replacing an existing jimmy proof lock or adding supplemental security.
