Lock specifications & compatibility
What’s Included With Your Lock Replacement
Every Yukon tool box lock replacement ships as a complete installation kit with everything you need to restore security to your storage. You’ll receive one precision-machined lock cylinder with integrated tumbler mechanism, a zinc-plated mounting bracket that matches the original factory hardware, all necessary fasteners and washers, and two identical keys cut to your lock’s unique code.
We also include a printed installation guide with clear photos showing each step of the replacement process. The guide walks you through removing your old lock (if still present), positioning the new cylinder, and testing the mechanism before final tightening. For customers replacing locks on our Yukon 46-inch tool box or other aluminum models, the entire process typically takes 8-12 minutes with just a Phillips screwdriver.
Lock Compatibility & Installation
Compatible Tool Box Models
This yukon tool box lock replacement fits all Yukon aluminum crossover, chest, and side-mount tool boxes manufactured from 2015 onward. The standardized lock cutout dimension of 1.25 inches ensures drop-in compatibility across our entire product line. If you own a pre-2015 Yukon tool box with a 1.125-inch cutout, please contact our parts department for the legacy lock model.
Installation Process
Replacement takes just three steps: remove the retaining nut from your old lock cylinder (or mounting bracket if the lock is missing), insert the new cylinder through the existing hole in your tool box lid, and secure it from the inside with the included bracket and fasteners. The rubber weather seal compresses against the aluminum to create a watertight barrier that prevents moisture intrusion. No adhesives, thread sealants, or specialized tools are required — we’ve engineered this system for straightforward installation in any work environment.
Materials & Weather Resistance
We manufacture every yukon tool box lock replacement from zinc-plated hardened steel to resist corrosion from rain, snow melt, and road salt exposure. The cylinder body receives a multi-stage plating process that creates a protective barrier against oxidation, while the internal pins and springs are made from stainless steel that won’t rust or bind even after years of use.
The integrated rubber weather seal forms a compression gasket around the lock’s perimeter when you tighten the mounting bracket. This seal keeps water, dust, and debris out of the mechanism, preventing the freeze-ups and corrosion that plague lower-quality replacement locks. We’ve tested this seal design through 500 hours of salt spray exposure and 100 freeze-thaw cycles without any loss of function.

Questions About Your Lock Replacement
This yukon tool box lock replacement is designed for 2015-present models with a 1.25-inch lock cutout. Tool boxes manufactured before 2015 used a slightly smaller 1.125-inch cutout and require our legacy lock model.
To verify compatibility, measure the diameter of the existing lock hole in your tool box lid. If it measures 1.25 inches, this replacement will fit perfectly. If you’re unsure about your model year or cutout size, contact our parts department with your tool box serial number and we’ll identify the correct replacement lock for your specific unit.
No specialized tools are required for installation. You’ll only need a Phillips screwdriver to secure the mounting bracket and retaining nut from inside your tool box lid.
The entire installation process takes 8-12 minutes on average. We include detailed photo instructions that walk you through removing the old lock (if still present), positioning the new cylinder, and testing the mechanism before final tightening. The lock is designed for tool-free removal and insertion — no drilling, cutting, or permanent modifications to your tool box are necessary.
Each Yukon tool box lock replacement includes two identical keys cut to your lock’s unique code. Both keys are precision-cut from nickel-silver blanks that resist bending and wear over time.
If you need additional spare keys, you can order duplicates through our key replacement service. We keep records of all lock codes shipped, so we can cut additional keys for your specific lock even years after your original purchase.
Yes, we’ve engineered this replacement specifically for all-weather truck bed use. The zinc-plated cylinder body resists corrosion from rain, snow, and road salt, while the integrated rubber weather seal creates a watertight barrier that prevents moisture intrusion into the mechanism.
We’ve tested this lock through 500 hours of salt spray exposure and 100 freeze-thaw cycles without loss of function. The internal pins and springs are made from stainless steel that won’t rust or bind in wet conditions. The lock operates smoothly in temperatures from -40°F to 140°F, making it suitable for any climate.
This lock ships with a pre-set 5-pin tumbler configuration and cannot be rekeyed without specialized locksmith equipment. The lock uses a different key profile than most automotive ignition systems, so matching it to your truck key would require custom pin fitting.
However, if you’re replacing locks on multiple Yukon tool boxes and want them to share the same key, contact our parts department before ordering. We can arrange to ship multiple locks keyed alike so one key operates all your tool box locks.
Our warranty covers all mechanical defects and premature wear on the lock cylinder, tumbler mechanism, mounting hardware, and keys. If your lock fails to operate smoothly, shows unexpected corrosion, experiences binding or sticking, or if a key breaks under normal use, we’ll send you a replacement kit at no charge.
The warranty does not cover damage from accidents, improper installation, or forced entry attempts. Normal wear from years of daily use is expected, but the lock should maintain smooth operation for well beyond the 2-year warranty period with occasional lubrication.
For optimal longevity, apply a small amount of graphite powder or dry lubricant to the keyway twice per year — once before winter and once in spring. Avoid oil-based lubricants, which can attract dust and gum up the pin mechanism over time.
Periodically check that the mounting bracket remains tight, especially if you frequently open and close your tool box lid. The lock cylinder should sit flush against the aluminum with no wobble or play. If you notice the lock becoming harder to turn or the key catching, clean the keyway with compressed air and reapply dry lubricant before forcing the mechanism.
