Replacement Keys, Locks, Straps, and Small Roof-Rack Hardware

First identify what the missing item does. A lock or key controls access to a rack or carrier. A strap may secure cargo or be part of an accessory attachment. A clamp, bolt, nut, or channel fitting may carry load or connect the rack to the vehicle. These roles are not interchangeable: a convenient-looking key, generic strap, or hardware-store fastener is not automatically suitable.

Record the lock, key, or part identity

Before contacting a dealer, photograph the whole rack or carrier and the lock face, product label, and missing component location. Record the product family, model or generation, serial number where present, key or core number, and market. If an old manual identifies a part number, keep that number with the product details.

Yakima key paths differ by lock and market

For a Yakima SKS lock that is already unlocked, Yakima’s current US Lost Keys instructions say to use the straight-edged Control Key to remove the core and read the code beginning with A followed by three digits. If the lock is still locked, the article routes owners to a registered-number lookup, a locksmith to pick the lock, or a local dealer who may have a master key set. Yakima explicitly warns against drilling the lock because it can damage the product and void the warranty.

Yakima’s US instructions separately describe older non-SKS locks used in products before 1993: a key number beginning with 0 on the lock face identifies the older style. The article gives replacement part number 88730XX, using the last two digits of the lock-face number; its example maps lock 050 to part 8873050. In the UK, Yakima’s FAQ gives a different retailer route: order key part number 8872 followed by the three-digit key number, or ask a signature store to identify an unknown number with its master-key set. These are market- and lock-specific identification routes. Do not combine the US and UK number formats or assume that a number proves a match to an unidentified core.

Rhino-Rack and Thule examples

Rhino-Rack’s US Masterfit catalog says a numbered key aligns with its corresponding numbered lock. For example, the current listing identifies RHINO-KEY059 as suitable for a B733 lock. That example does not identify the lock fitted to another leg or accessory. Rhino-Rack’s FAQ directs owners to a dealer or to the key and part numbers in the product instructions.

For a Thule Motion 3 roof box, the manual recommends recording key numbers and gives the BA No. on the sticker inside the lid for spare-part questions. Use that identifier for the Motion 3 support request; it is not a universal identifier for other Thule products.

Match straps and hardware to their job

Check the complete product page and instructions for the accessory that uses the part. A Rhino-Rack catalog example lists SP334 as a two-pack of replacement multi-purpose straps for its RMPHU holder. Another lists SP125 as a replacement clamp plate for the S510, S512, and S512X kayak carriers. The named product family is the boundary of each example. It does not show that the strap or clamp suits another carrier.

For a missing nut, bolt, washer, or security screw, use the rack or accessory’s exact part number and installation document. Diameter and length alone do not confirm thread, material, strength, interface, or suitability for the connection. Do not substitute a generic fastener or use a torque value from a different product. If a structural fastener, clamp, or attachment part is missing or damaged, keep the affected rack out of use until the manufacturer or a qualified dealer confirms the correct repair.

Check the local order route

Support, catalog, and stock can vary by country. Yakima’s UK FAQ routes replacement parts through retailers and notes that some parts may need to be sourced from overseas. Rhino-Rack’s US FAQ points owners to local dealers for spare parts and part-number identification. Thule’s regional support pages may offer different search, dealer, or service routes. Confirm the item, current instructions, package contents, availability, and return terms with the support channel for the product’s market before ordering.

Keep the confirmed key or part number with the rack records and vehicle instructions. An exact key match solves a lock-identification question; it does not establish that the rack fits a vehicle. Likewise, a replacement strap or fastener should only be used for the purpose and system stated in its current instructions.
