Very good for the price, work a treat.
Got these as I couldn't find the original keys and they work a treat. Very easy to fit, they look and work just fine but are not the same quality as the original, but at this price, what do you expect. They do the job. After installing them, I found my original Thule keys... typical.

Work well, smooth operation.
Straight fit for my summit roof bars whose locks suffer from the keys getting stuck inside. These work absolutely perfectly. No doubt they fit brand originally designed for too, this type of lock is pretty universal.

Definitely not a genuine Thule item but does the job. Took 5 days longer to arrive than quoted but I was informed. Very good for the price and I now have spares as I only needed one. No numbers on the keys but good strong keys. Would recommend.

Fiddly yes, does the job ? Resounding; Hell Yeah !
I was resigned to the fact I had lost a lot of money by losing the keys to my bike rack I saw this and thought; well for less than a fiver it’s worth a go Reading the reviews I was sceptical but am happy to report a resounding success. The master key is difficult to insert especially as the rack was not fastened but this is a lock so do expect to have to fiddle a bit and ensure the master key is all the way in and then the old lock just pops out New lock again a little fiddling will get it inserted and that’s it job done Now I don’t write reviews normally but felt compelled to put my thoughts down as I am so impressed Male, UK, late 50s, size 7, overweight, no banana for scale

Master key didn’t fit my prorides, but managed to get old locks out with a paper clip. Lock barrels fit a dream.

Good budget option
Great budget locks. Fit well and will do the same job as the genuine product. There were no instructions included but easy installation.

They fit and work as if they’re were the real deal
While I won’t be able to get matching Thule locks going forward, I don’t think that going to be a big deal since the locks are only going to be used for this set of bars for ever and ever. The install went smoothly with the tips from other reviewers (push in the copper colored tang as you insert into the plastic mount). Lock and unlock works - even after a trip through a snowstorm. Buy!

Does the job as the original one!
They fit perfectly and work seamlessly with Thule bike racks and roof racks. Easy to install and reliable, they offer excellent value. Compared to the original Thule lock cores, this one does the same job for a much better price! A great budget-friendly alternative!!

Perfect
Had to work a vit to get the old ones out since I lost the key. A bit of work to install the new ones but they work perfectly as described. I definitely recommend these.
