Locks that work

£24 with delivery. It seems too cheap! Isn't there some sort of quality issues with it? For OnGuard, I've heard of keys made of soft metal that breaks and really bad weather-proofing. Although I don't know if either of those applies to that specific lock.

Onguard have changed the lock and key design in their new 8000 series range. It is now a pinned lock with the coding cuts on the inside edges of a 'z' profile key, so the key ought to be stronger than the old design, and there are no discs to get misaligned and it shouldn't be possible to turn the key if it is not fully inserted.

The previous model 5000 series Onguard locks used a disc key, as do Kryptonite and Abus. As the disc lock keys are double sided, deep coding cuts make the key thinner, creating a weak point where it could snap if the mechanism gets stiff and rusty, or the key hasn't fully inserted and sticks when turned.

The quality is inferior to my Krypto mini D and I'd feel less happy leaving it out in the rain.

But, at a third of the price of a fag mini I decided to go for it. I didn't want an everyday lock, just something for longer term storage and use in higher crime areas. On that basis, it seems spot on.
