  • Halfords Locking Fuel Cap (XS737) is rated 3.5 out of 5 by 17.
    Rated 5 out of 5 by from There is a twist, but highly recommended. In order to open the cap, it needed to be locked first then rotate it anti-clock wise. I spend like 10 Minuit at the fuel station trying opening it and couldn’t get any hold of it. Cos, when you unlock it then rotate it just keeps spinning. Then I locked it and then rotated it , and that was a bingo. That means it cannot be opened without the key just make sure nobody steals your fuel. But, some clear instructions on the package would be helpful. Highly recommended.

    Rated 5 out of 5 by from great products sound that there are few idiots who tried it and it didn't work for them. most locking fuel caps will rotate as they are locked so no one can break the cap. sounds that those people never used locking caps in the past.

    Rated 2 out of 5 by from Utterly barking perverse logic This review refers to the "SAKURA LOCKING FUEL CAP". The Halfords advice is quite correct. Essentially, when the cap appears to be locked, i.e. rigid and not moving, it is in fact UNLOCKED and can be turned open. When it moves and spins freely, it is in fact LOCKED and cannot be opened. The logic behind this is so bizarre and perverse it could almost be French. Once you get past the complete stupidity of that, and understand how it actually operates, it does work. What is even more bizarre and worrying, is that Halfords stock a product that works contrary to all other similar products, but that does not come with any instructions or advice whatsoever. This really does them no credit at all.

    Rated 5 out of 5 by from Excellent Read one or two negative reviews on this fuel cap,but decided to give it ago despite people saying they couldn't unlock it once fitted. Fitted cap ( KIA Sportage2012) prior to leaving for France and it works like a dream, couldn't understand why people can't use the cap! Easy to use and to unlock !!!!

    Rated 5 out of 5 by from Just the job Having had my perfectly good quality cap 'replaced' with a damged one when I used meet & greet parking for 2 weeks, I urgently ordered a locking one from Halfords. Swift delivery by DPD and item was superb. I had previously read other reviews, and replies, and had no problems fitting the new cap. However, I have every sympathy with problems encountered by other people as the packaging contained NO fitting instructions whatsoever.
