The best lock for your Thule roof rack
Perfect fit in my Thule roof rack system. Keeps the system safe from theft. Two minutes to install all 4 locks. Works great.

Lock & Load
Replacing your lock cylinders with this kit is guaranteed to have you grinning like the Cheshire Cat! Short money & zero drama. Two keys plus the removal/installation key are included. No other tools required & done in minutes. Highly recommended.

Easy install, one key for all!
These keys are compatible with every Thule system, and work like a standard lock. Once you put it in the product, that product will be likely protected by theft and personally, coming in an area with a lot of stolen Thule, this is a life saver. Worth the money.

Good Product, Typical Horrible Thule Instructions
I like Thule products and have for a long time - excellent design, look and function that compliments nicer vehicles. Something that is truly lacking for Thule however is intuitive meaningful instructions for their products. I understand the predominant use of pictures alone so everyone can understand but even their video instructions don't provide quality, necessary details to install their equipment. I'm a very handy DIY'er and have struggled with several of their products. This One-Key system was used to key alike all the locks on our rooftop box and rack. Once I found a simply, reasonable non-Thule instruction video online, the swap out was a breeze. Everything is now keyed alike and protected. Good luck out there and definitely seek out some non-Thule instructions when attempting to install their products!

One key for all Thule racks I have!!!
I trust Thule with all my expensive toys such as bikes and skis but sometimes key is getting lost. I bought 6 pack replacement cores and install them on my bike and ski racks. Installation is simple and fit is perfect. Works like a charm and having one key for all of them is important to me. I suggest to buy spare keys with the same key number and hide it somewhere for the future.

Work great, easy installation!
I used these keys for our Thule XT L Roof box and Rail Feets - 4 locks for the Rails Feets and 2 locks for the Roof box. The installation of all 6 locks was made within 2 minutes, very easy and they fit pretty well! So far very happy with these locks.

Un valido oggetto per semplificar la gestione delle serrature
Ho acquistato 2 portabici da tetto thule pro con 4 serrature, e avevo giร in uso un box tetto di 11 anni con 2, e per avere meno chiavi in giro ho optato per un set di 6 cilindri. Devo dire che fa il suo dovere, e i cilindri sono compatibili anche con il "vecchio" box, installazione rapidissima grazie alla chiave master in dotazione con il set. Per quanto riguarda quelle dei portabici si smontano dalla posizione "sbloccata/aperta", per il box invece la posizione รจ intermedia visto che ha il blocco per evitare di sfilare la chiave dalla posizione di apertura. Come riportato da altri utenti ho ingrassato i cilindri nuovi prima di inserirli.
