9-Pin Anti-Pick Radial Lock Mechanism
AL-KO Wheel Locks incorporate a sophisticated 9-Pin Anti-Pick Radial Lock Mechanism, representing a significant deterrent against unauthorized access. This advanced locking system utilizes nine precision-engineered pins within the cylinder, creating a complex configuration that is exceptionally difficult to manipulate.
The radial design further enhances security by distributing stress across the pins, resisting drilling and forcing attempts. Unlike simpler lock mechanisms, this system offers a higher level of protection against picking tools and skilled attempts at bypassing the lock.
This feature is a key component in achieving Sold Secure Diamond Approval, demonstrating AL-KO’s commitment to robust security solutions for caravans and trailers.
Galvanized Steel Construction for Robustness
AL-KO Wheel Locks are engineered for enduring reliability through the use of galvanized steel construction. This robust material choice provides exceptional strength and resistance to corrosion, ensuring long-lasting performance even in challenging environmental conditions.
The galvanization process coats the steel with a protective zinc layer, shielding it from rust and weathering. This is particularly important for trailer and caravan security devices, which are often exposed to the elements during storage and travel.
Furthermore, the sturdy steel build contributes to the lock’s ability to withstand lateral forces, making it more difficult to forcibly remove or damage. This feature enhances the overall security and peace of mind for vehicle owners.
Alloy-Specific Inserts for Optimal Fit
AL-KO Wheel Locks prioritize a secure and precise fit with their alloy-specific inserts. Recognizing the diverse range of wheel designs, AL-KO provides inserts tailored to different alloy wheel types, ensuring maximum protection.
These inserts fill the gaps between the lock and the wheel, minimizing movement and preventing potential tampering. A close fit is crucial for resisting leverage attacks and maintaining the lock’s effectiveness.
Each lock comes with a rim-specific insert, carefully chosen to match the wheel’s profile. This attention to detail enhances security and prevents damage to both the lock and the wheel itself, offering a truly customized security solution.
Sold Secure Diamond Approval – Security Standard
AL-KO Wheel Locks boast the prestigious Sold Secure Diamond approval, representing the highest level of independent security testing and certification. This rigorous evaluation confirms the lock’s exceptional resistance to various attack methods, including drilling, sawing, and picking.
Achieving Diamond status signifies that the AL-KO Secure Wheel Lock has surpassed stringent criteria set by Sold Secure, a leading UK-based security accreditation body. This provides caravan and trailer owners with confidence in the lock’s ability to deter theft effectively.
Being the only product on the market with this level of security, it’s a testament to AL-KO’s commitment to providing superior protection against wheel theft, often leading to insurance discounts.
Determining Your Wheel Lock Size
Accurate sizing requires measuring wheel diameter, identifying the bolt pattern, considering rim depth, and knowing if wheels are steel or alloy for a secure fit.
Wheel Diameter Measurement
Precisely measuring your wheel diameter is the foundational step in selecting the correct AL-KO wheel lock. This measurement dictates the size of the locking bar needed for a secure and effective fit. To determine the diameter, you’ll need a measuring tape or ruler.
Begin by deflating the tire slightly to allow for accurate measurement. Then, measure the distance across the wheel, passing through the center of the wheel. Ensure the tape measure is taut and straight. This measurement, in inches or millimeters, represents the wheel diameter.
Crucially, this is the overall diameter, including the tire. Refer to the AL-KO size chart (detailed later) to match your measured diameter with the corresponding wheel lock size. Incorrect diameter measurements will lead to incompatibility and compromised security.
Bolt Pattern Identification
Identifying your wheel’s bolt pattern is essential, though less critical than diameter for AL-KO wheel lock selection, it contributes to optimal fitment. The bolt pattern refers to the number of wheel studs and the diameter of the circle they form.
To determine this, count the number of studs on the wheel. Then, measure the distance (in millimeters or inches) from the center of one stud to the center of the stud directly opposite it. This is the pitch circle diameter (PCD).
The bolt pattern is typically expressed as “X/Y,” where X is the number of studs and Y is the PCD. While AL-KO locks aren’t directly bolt pattern specific, knowing this information aids in confirming compatibility and ensuring a snug fit against the wheel.
Rim Depth Considerations
Rim depth, or the distance from the wheel mounting face to the rim’s outer edge, plays a crucial role in AL-KO wheel lock compatibility. Deeper rims generally require a longer locking bar to ensure secure engagement with the wheel and chassis.
Insufficient rim depth can prevent the locking bar from fully extending, compromising security. Conversely, excessive depth isn’t usually an issue, as the AL-KO locks offer adjustment. However, it’s vital to select a lock model designed to accommodate the specific rim depth range of your wheels.
Consult the AL-KO Wheel Lock Size Guide PDF to find the recommended lock for your rim depth, ensuring a secure and effective theft deterrent.
Identifying Specific Wheel Types (Steel vs. Alloy)
Determining whether your wheels are steel or alloy is critical for selecting the correct AL-KO wheel lock. AL-KO designs specific inserts to ensure a snug, secure fit, maximizing protection against theft. Alloy wheels, being softer than steel, require a more precise fit to avoid damage during lock application.
The AL-KO Wheel Lock Size Guide PDF emphasizes the importance of using alloy-specific inserts with alloy wheels. These inserts prevent scratching or deformation of the wheel material. Steel wheels are more robust and can generally accommodate a wider range of lock fits, but a precise fit is still recommended.
Always verify your wheel material before purchasing a lock.

Initial Fitting Procedure – Using the Wheel Bolt
According to the AL-KO Wheel Lock Size Guide PDF, the initial fitting process is straightforward, yet crucial for optimal security. It begins with screwing a special wheel bolt into a designated screw hole within the wheel rim.
This bolt serves as the anchor point for the locking mechanism. Following this, the distance is carefully set using the adjustment bolt provided within the kit. Precise adjustment ensures a snug and secure fit.
Subsequently, the locking bar is pushed through the rim, followed by fitting the wheel claw. Finally, the cylinder lock is engaged, effectively securing the caravan. This process, when executed correctly, transforms your caravan into a protected asset, deterring potential theft and providing peace of mind.
Adjusting the Locking Bar for a Secure Fit
As detailed in the AL-KO Wheel Lock Size Guide PDF, achieving a secure fit relies heavily on correctly adjusting the locking bar. After inserting the bar through the wheel rim, it’s vital to ensure it’s firmly positioned against the chassis.
The adjustment bolt plays a critical role here, allowing for fine-tuning to eliminate any slack or movement; A properly adjusted bar will resist lateral forces, preventing the wheel from being rotated even under significant pressure.
This meticulous adjustment is paramount for maximizing the wheel lock’s effectiveness. Regularly check the bar’s tension, especially after traveling, to maintain optimal security and deter potential theft attempts.
Regular Maintenance Checks
According to the AL-KO Wheel Lock Size Guide PDF, consistent maintenance is crucial for ensuring the continued reliability of your wheel lock. Periodic inspections should focus on the locking mechanism, checking for any signs of wear, corrosion, or damage.
Verify the locking bar moves smoothly and engages fully with the chassis. Lubricate moving parts as needed to prevent stiffness. Examine the galvanized steel construction for any rust, addressing it promptly to maintain robustness.
Regularly confirm the rim-specific insert remains securely fitted, providing optimal protection. These checks, performed before each journey, guarantee your AL-KO wheel lock remains a dependable security measure.
