Product Information
Full details
The Thule One-Key System 4-Pack is designed for outdoor enthusiasts who use multiple roof-mounted accessories and want to simplify their security routine. Its primary benefit is the ability to operate every Thule lock cylinder with a single key, saving time and reducing keychain clutter; however, users should note that the cylinders are specifically designed for Thule racks and may require specific adapter plates depending on the accessory generation.

FAQs
Can I order more locks that match this set?
Yes, Thule offers additional lock packs that can be keyed to match your existing cylinders based on the key number stamped on the lock.
Will these work on my Thule roof box?
Yes, the One-Key system is compatible with nearly all Thule roof boxes that utilize the standard Thule lock cylinder housing.
What should I do if I lose my last key?
If you lose all copies of your key, you will likely need to drill out the cylinders to remove them, as there is no universal key for these locks.
Is this system weather-resistant?
Yes, the lock cylinders are designed for exterior automotive use and are resistant to rain, snow, and road debris.
Does this set include the master key?
The set typically includes the standard keys for operation; the change key (master) is usually provided with your original roof rack purchase.
Troubleshooting
Key does not turn inside the lock
Ensure the key is fully inserted into the cylinder and check that the lock housing is not misaligned with the mounting point.
Cannot remove old lock cylinder
You must use the original master (change) key to disengage the retaining pin. If you have lost the master key, you may need to consult a locksmith or contact Thule support.
Pros and Cons
Pros
- Reduces keychain clutter significantly
- High-quality, durable lock cylinders
- Easy to install without professional help
- Works across different types of roof accessories
Cons
- Not compatible with very old legacy rack systems
- Installation requires the master key if replacing existing cores
- Can be difficult to remove if cylinders are jammed
Setup, Compatibility & Care
To install the locks, ensure your current accessories have an empty lock housing. If you are replacing existing cores, you must use the 'change key' (master key) that came with your original locks to remove the old cylinders. Simply insert the change key, pull the old cylinder out, and slide the new One-Key cylinder in until it clicks. For maintenance, it is recommended to spray a small amount of graphite lubricant or a dedicated lock lubricant into the keyway once or twice a year, especially if you live in an area with high moisture or road salt. Avoid using heavy oils or WD-40, as these can attract dust and grime, eventually causing the internal tumblers to stick.
