I have been thinking about what makes a lock diffucult to bump. Here are a few things that come to mind:

1. dirty/corroded/weathered/worn out locks (includes non working locks)
2. locks pinned close to MACS (Max Adjacent Cut Standard)
3. locks with pins that are the longest allowed for that lock
4. locks mounted in tight quarters

So what else makes a lock diffucult to bump if you have a correctly cut key?



Bump it to the next level.

and the force of the hit.

Good point.


Locks installed with the pin chambers on the bottom instead of the top. I don't even like to pick locks that are installed like that.

if you have visine or whatever,spray it in the key way...the salt in it will help melt the ice,although it cant be good for locks:) or the water hose if its working.

Never put water in a lock when the temperature is below freezing. Heating the lock would be a better approach or even a deicer.

Of course, this Frozen Lock thing is under the Weathered Lock category.

I have had to deal with frozen locks due to freezing temperature. Most of the locks were automotive. There are a few tricks and I'll share one that has never failed me.

You use the key for the lock to thaw the lock. If you have access to a hair drier and electrical power that works. If not a cigarette lighter does a great job. What you do is heat the key with it out of the lock. Then put the hot key in the lock. Repeat if necessary until the lock is unfrozen and working.

Rain, snow, sleet, freezing rain, rain wet lock with a significant temperature drop to freeze the lock would appear to be weather related....could be wrong.
Bump it to the next level.

I have been thinking about what makes a lock diffucult to bump. Here are a few things that come to mind:

1. dirty/corroded/weathered/worn out locks (includes non working locks)
2. locks pinned close to MACS (Max Adjacent Cut Standard)
3. locks with pins that are the longest allowed for that lock
4. locks mounted in tight quarters

So what else makes a lock diffucult to bump if you have a correctly cut key?



These are important factors which makes lock hard to bump and you focused on good point.
