To make a long story as short as possible, our storage unit was broken into last week. Management is allowing us to use an over lock plate (aka a lock-out plate) to add a padlock, in combination with the existing cylinder lock (that is what it is called on the packaging at A-1 Self Storage). Here is a link to a photo showing the configuration (on someone else’s unit): lock-out plate, padlock and cylinder lock: http://www.a2zwriting.com/images/A-1_Lo ... ration.jpg
The regional manager talked with me extensively today about recommendations for the type of padlock we should get. He said he once counted that in his many years working for storage facilities, he has removed no less than 50,000 locks from storage units! But not by picking them. Rather, by using tools to knock or pry them open or off or cut them open. On the basis of that experience, he recommended locks that he said he hated most to have to remove. His top recommendation was the Master Magnum Lock (M50XKAD). But when I went to YouTube, I found that this lock, although it may be very annoying to cut off at the shackle, can be picked relatively easily.
At that point, I realized that there seem to be two dimensions involved: (1) the level of difficulty with which a lock can be knocked, cut or pried open/off and (2) the level of difficulty with which it can be picked.
The padlock I wish to locate should meet these three criteria:
1. Difficult to pick
2. Difficult to crack, cut or hammer open
3. Shackle diameter not larger than 8 mm (to fit into the hole where it must go)
Here is some other information about me that may be helpful:
Location: California.
Budget: Willing to pay whatever the best padlock for the circumstances costs.
Threat level: The two men who broke in previously may reattempt at any time.
Shackle diameter: No more than 8 mm.
Level of lock sought: Top of the line under the circumstances.
Lending: Not likely that we will ever lend the keys to anyone.
Thank you in advance for any assistance rendered! If any additional information or clarification is called for, just let me know.
