Secondary Locks

Wouldn't recommend the On-Guard. I'm on my second one in 6 weeks, both jammed for reasons I don't understand. Used every day so have got a bit wet but I'm pretty conscientious about using wd4o on almost a weekly basis, having been caught out with a jammed lock in the past. First lock jammed whilst stuffed in my pocket, key would go in and out but wouldn't turn. To be fair to the uk distro guys they replaced it without batting a lash. Unfortunately the second lock has jammed in exactly the same way after only being used for about a week, this time looped on the frame. I'm pretty sure that I've just been unlucky having two locks go wrong on the trot, but as above a quick look on-line soon tells you that the random jamming is a bit of an issue. Just ordered a Fagh... won't be skimping on the cost of a lock again!

It might be the WD40. I've used GT85 on lock mechanisms without any problems but have recently heard it's best to use a dry graphite lubricant.
