The key broke inside the lock hole !

The key broke inside the lock hole ,Jamming the whole lock! Had to go home to bring back a power cutter in the middle of the night to cut it ... Embarrassing !

Hi B I,

We apologise for the terrible experience you had while using our product.

I will forward your feedback to our product team and they will look into improving the integrity of the keys we provide with the locks.

Avoid This Lock, customer(s)!

I use a quality Kryptonite Evolution D-lock and cable for my main bike lock, but I bought this one 18 months ago as a cheap lock to use simply to secure my front wheel (wheels with quick-releases) and provide some extra deterrent to thieves. This morning the key snapped when I was engaging the lock: yes really. By sheer luck I was able to open the lock again by pressing hard the half of the key that I still had against the other half remaining in the lock and turning it to open. Otherwise I would have had to walk home and return to the library with a drill, crow bar and any other tools that might break the lock. I am not the first customer to post a review that involves the key of this lock's snapping off. I had a lucky escape, but YOU may not be so lucky, dear customer(s). You have been warned :) !

Thank you for your comments regarding the key in this lock.
I have passed this information on to the team in charge of this item at b'Twin.
Please return the item to us for a refund or an exchange as you have a 2 year warranty with this item.

Multi utility Lock

This Lock is a very unique one which let me roam free after parking my bike near jogging track along with any kind of pole or fixed hook and easy to remove also and I some time hang my bike with slim rod fixed for advertising so reliable one can lock bike helmet also. Thanks to team Decathlon for a unique product

Malfunctioning - Bike lock

I bought this lock with lot of expectations, that it safe guard my things. But it is very bad that the lock itself was very tight at the beginning, I was not able to unlock due to tightness. Also now the lock is almost broken , and I am realized that the lock is dependent on a single small(tiny) nut and it came out last day.. Totally disappointed.. Not expected from a decathlon product.. It would be better if you replace us this lock with some other good lock.

Dear Annet,

Thank you for taking time out to review our product. I am sorry our bike lock did not meet your expectations. All our products pass the quality tests. In spite of this, I suspect you received a defective piece.

Please feel free to visit your nearest Decathlon store to proceed for an exchange or return. Hope this helps.

Thank you!

Key snapped too thin

I have a Decathlon cable lock which was cheaper and has a fairly solid key. This however has a very thin key. As a result the key bent and snapped off in the lock on the second use. Total ripoff

Dear Sir,
I'm sorry to read that the lock has snapped on this lock. Please return it to us for a refund or an exchange.
