Setup and Installation
Follow these steps to correctly install your Proven Industries Model 2517-D Trailer Lock:
- Choose the correct lock: Ensure you have the Model 2517-D, which is compatible with your coupler size and type (stamped Demco-style 2 5/16-inch or cast Hit N Hitch 2 5/16-inch).
- Insert the inner slide: Place the inner slide component into the coupler and engage its latch mechanism.
- Insert safety chains: If applicable, insert the S-hook style safety chains into the designated chain locking compartment within the inner slide.
- Place the outer shield: Position the all-encompassing outer shield over the inner slide and the coupler.
- Secure the puck lock: Place the provided puck lock over the two tabs on the outer shield and securely lock the cylinder using the key.

Operating Instructions
To operate the Proven Industries Model 2517-D Trailer Lock:
- Locking: After following the installation steps, ensure the puck lock is fully inserted and turned with the key until it clicks into the locked position. Remove the key. The lock is now engaged, securing both the coupler and any inserted safety chains.
- Unlocking: Insert the key into the puck lock cylinder and turn it to the unlock position. The puck lock can then be removed from the outer shield. Carefully remove the outer shield, then the inner slide from the coupler.
Always ensure the lock is fully engaged and the key is removed when leaving your trailer unattended.
Maintenance
Regular maintenance helps ensure the longevity and reliable operation of your trailer lock:
- Cleaning: Periodically clean the lock components with a damp cloth to remove dirt, dust, and debris. Avoid harsh chemicals that may damage the finish.
- Lubrication: Apply a small amount of graphite lubricant or a silicone-based spray to the keyhole and internal locking mechanism every 6-12 months, or more frequently in harsh environments. This helps prevent corrosion and ensures smooth operation.
- Inspection: Regularly inspect the lock for any signs of wear, damage, or corrosion. Ensure all components fit together securely. If any part appears damaged, contact Proven Industries for assistance.
Troubleshooting
If you encounter issues with your trailer lock, consider the following:
- Difficulty inserting/removing key: Ensure the key is fully inserted and oriented correctly. Apply a small amount of lubricant to the keyhole. Do not force the key.
- Lock mechanism is stiff: This can be due to dirt or lack of lubrication. Clean the lock and apply lubricant as described in the Maintenance section.
- Lock does not fit coupler: Re-verify your coupler type and size against the compatibility information. The Model 2517-D is designed for specific stamped Demco-style 2 5/16-inch and cast Hit N Hitch 2 5/16-inch couplers. If it does not fit, you may have an incompatible coupler.
- Puck lock does not engage: Ensure the inner slide and outer shield are correctly seated on the coupler, allowing the puck lock tabs to align properly.
