Thule One-Key System lock cylinders 2-Pack, Silver/Black — keyed alike with Comfort key for unified Thule accessory security

The Thule One-Key System 2 Pack replaces two Thule lock cylinders so multiple accessories open with the same single key.

If you own several Thule products that use lock cylinders, swapping them to a single key makes daily use and security management far simpler. This two-pack includes two lock cylinders in a silver/black finish plus the grip-friendly Thule Comfort key, so you can standardize locks across racks, carriers, and boxes without changing your accessories. Installation is quick and compatible with Thule systems that accept replaceable cylinders.

How do I install these replacement lock cylinders?

Installation is designed to be straightforward and fast: remove the old cylinder from your Thule product, insert the new One-Key cylinder, and secure it according to the product’s instructions. No specialized tools are typically required beyond basic hand tools that you likely already own.

• Remove retaining screw or clip on the original cylinder
• Slide out the old cylinder and align the new cylinder in the housing
• Tighten the retaining hardware and test the included Thule Comfort key

Will one key really work across all my Thule accessories?

Yes — the One-Key system lets multiple compatible Thule products use the same key when fitted with matching cylinders. That means you can convert individual locks on bike racks, roof boxes, hitch carriers, and other Thule accessories to share one key for easier access.

• Set of two cylinders keyed alike for immediate use
• Works with Thule products designed for replaceable cylinders
• Add more cylinders later to expand the single-key setup

What are the physical specs and included parts?

The pack contains two lock cylinders finished in silver/black and one Thule Comfort key built for easy grip. Package dimensions are compact, making storage and transport simple if you’re carrying spares or installing on the go.

• Two lock cylinders in silver/black
• One grip-friendly Thule Comfort key included
• Package dimensions: 5.7" L x 2.9" W x 1.3" H

Can I use these locks outdoors and on different vehicles?

These cylinders are intended for the Thule accessory family and perform well in typical outdoor conditions when installed correctly. Compatibility depends on whether the accessory accepts replaceable cylinders, but once installed they serve across vehicles and environments where your Thule gear is mounted.

• Designed for use on Thule racks, boxes, and carriers with replaceable cylinders
• Durable finish suited for regular outdoor use
• Standardized key reduces the need for multiple keys across vehicles

Who is this for? The Thule One-Key System 2 Pack is ideal for anyone who owns two or more Thule accessories and wants the convenience of a single key. It suits families, commuters, and outdoor enthusiasts who juggle roof boxes, bike carriers, and cargo solutions and prefer streamlined access and simpler key management. Install these cylinders to simplify daily use, reduce lost-key hassles, and keep multiple Thule products keyed alike without buying new accessories.
