Secure your trailer coupler with your vehicle’s ignition key using BOLT’s proprietary One-Key technology. This stainless steel barbell-style pin adjusts in 3-millimetre increments to fit virtually any coupler latch on the market, eliminating the need for separate hardware when towing. The sealed stainless steel shutter protects against dirt, rain, and salt spray—critical for marine environments and coastal travel.

Built with a plate-tumbler sidebar mechanism that resists picking and bumping techniques, this lock codes to your vehicle’s key automatically on first use. Backed by a limited lifetime warranty.
