BiLock defeated....

[SnowyBoy]

So I've been trying to pick this for weeks as I don't have a key and really wanted to make a cutaway. I went to the shed earlier to make a very crude tension tool, popped the lock in the vice, was satisfied with the tension tool, dropped the pick in, had a jiggle & it pops open in 35 seconds



Got an FG here too with no key... should be fun!

[SnowyBoy]

While I'm here would anyone care to explain why there are two pins with long slots instead of holes?

I kinda feel like I've only picked a 10 pin because of these

[fgarci03]

Wow NICE ONE!

35 seconds? That must be a record
Congrats on the picking!

Long slots are for master keying. Nice work picking it, I've got nowhere closer with mine.

Like I said, I have been at it for weeks and weeks. I've been trying all sorts, front to back, left then right, a bit here a bit there... I'm not sure where the element on the NG will come in to play. It's bad enough having two rows of pins to choose from.

On the flip side, I have a simple 5 pin lockwood that I just can't get. This is why I could never do this professionally >_<

AFAIK Bilock make all possible 15 pin variations, 4 'regular' and 11 for masterkeying and maison applications. A heavily masterkeyed or maison cylinder would be easier to pick than a regular one. To maintain security, no more than 3-6 pins should be 'masterkeyed', use rotating constants if need be and there should be a level 4 pin (not masterkeyed) in each leg near the front of the cylinder (both front cuts being level 4 is deprecated as key strength is compromised) to make it harder to insert picks.

It seems there are 'limited edition' variations which are sold to Australian government agencies where maximum security is required. These would have additional anti-pick tricks.

The element on the NG needs to be moved to the limit of its' movement (up or down depends on your lock orientation). That allows the very front of the sidebar to the right if the pins are at the top of the keyway to move inwards when the pins on that side are manipulated. Have just used a modified hook to lift it, and left the hook in place while picking. Got that idea from watching a video by FarmerFreak.

The element has no effect on the other sidebar.

Fantastic job picking that lock so quickly!

FINALLY!

I'm not alone now

Perhaps something like 23920 ?

I can see the split on the front stack so I know she is quite high lift. I'm just going to lift and jiggle it... will pop eventually!

It's driving me mad! Not one single pin binds... knowing my luck it probably by chance had the most perfect tolerances where no pin comes before the next

[fgarci03]

@Snowyboy:
Try to rake it. Many locks where "I don't feel any binding" I can rake pretty fast with a half diamond (don't ask me why!). After doing that a couple times, I start to feel some bindings there.

LOL I know this doesn't make any sense but it happens to me. Maybe because when raking you do get an idea of what your are doing and feel when pins set. And when SPP'ing afterwards you try to replicate that. I don't know

Hay Snowy! Nice job! Any chance of a pic of your tensioning tool?

That one was rubbish... I'm ashamed of it :/

This is the latest and works much better. Very solid grip!

It is filed with a slant to enable clearance for the bow of the pic. The thickness needs to be spot on or it wont grip and twists out of the slot.

Forgot to mention in the photo you would use clockwise tention
