Easy to open (by feel) combination locks

[nothumbs]

These locks are small enough, just palm a replacement, and open that one.

i have been opening a Lockwood 3 wheel combo lock by feel for a few months now, they are really easily,once you get the hang of it.Look for baggage locks these can be found at airports and local hardware shops.

I hope that helped.Check online as well, you might find a supplier somewhere.

Try luggage stores or camping/travelling retailers.

I've seen them sold at Walgreens, Walmart, Target, etc...
