I need high security padlocks.

[SikkerLass]

Hi.

I need a high security padlock for a locker(like those in gym changing rooms), one for locking a bag and one for locking 2 handles on a suitcase together.

Besides that I need to chain and lock a big box.(locking the chain around the box, with a padlock)

Last but not least I would like to have a lock for doors on hotel rooms, guest rooms, motel rooms and other rooms I sleep in, when visiting people.

So far I have been looking at theese padlocks:

Squire SS65CS CEN 6 rated high security padlock with Evva ICS patented key

MUL-T-LOCK #18 E-Series Padlock with High Guard (11/16" Shackle)
(at: MUL-T-LOCK #18 E-Series Padlock with High Guard (11/16" Shackle)).

I would like suggestions.

I have tried to search the forums for answers before posting. In case i missed relevant posts,I'm sorry, I tried.

Kind Regards

Last I heard, the Mul-T-Lock E18 series locks were discontinued years ago.

Before you order the huge padlocks with thick shackles, I can assure you that they will probably not fit onto gym lockers. Most of the gym lockers I have seen will accept at most an 8 mm diameter shackle. So be sure of the size you need before you spend a lot of money for a padlock that won't fit where you need it.

When you talk about locks for hotel rooms, guest rooms, motel rooms and other rooms you sleep in, are you referring to some sort of secondary lock that does not modify the door? Because if you are intending to change out the motel's door locks for the duration of your stay, you will run into legal problems quickly.

You can try searching eBay or Amazon or some other place for "Portable Door Locks". None of them will fit all doors, and some are so cheap as to be laughable. I used to use a couple of forks, one bent, when I traveled. But most of the portable door locks require a decent amount of space between the door and the frame to operate.

What Gordon said. If you spend a lot of money on a hugh high security padlock and put it on a cheap/flimsy gym locker, it's going to signal to a would-be thief that there may be something valuable in there, and he's just going to ignore the lock and attack the locker door itself. Many locker systems have known weaknesses that allow them to be opened quickly and easily without even destroying the door.

Rather than focus on super high security shrouded locks with giant thick shackles, I'd suggest you go for a smaller shackle and focus instead on material. Look for something hardened or steel that is alloyed with molybdenum, boron, etc. Also get a good cylinder that is resistant to common manipulation techniques. A Protec2/Protec, BiLock NG, Assa Twin Combi, or Schlage Everest Primus would all be good choices (in roughly decreasing order of picking difficulty).

If I was looking to deploy a high security padlock but something that was discreet about it, like for the exact type of scenario it sounds like you need, I would probably go with this one:

If you have something in a gym locker (or similar) that warrants a lock like that, maybe it shouldn't be there in the first place?

Is your threat forced entry or an unnoticed entry?

I'd second the recommendation to consider your threat models: For example, for a gym-locker lock, a) by the weakest-link principle, there's only so much protection a high-end padlock can give you because most lockers themselves are rather flimsy, so I'd hesitate to spend $150-200+ there -- it would be like putting an ANSI Grade 1 deadbolt on a screen door. b) in a locker room, thieves would be going for quick hits to avoid getting caught in the act, which means the most likely threats would probably be either a small/medium set of bolt-cutters or a set of bought/improvised shims. Bumping would make way too much noise, and picking would take too long, assuming they're not a locksmith, a lock-sport champ, or Jason Bourne. Therefore, feature-wise I'd emphasize resistance to shackle-cutting and shimming. Even a lot of lower-end lock makers have wised up and added shim resistance in recent years, but the cutting-resistance part is tougher here given that the relatively small latch on most lockers limits the shackle diameter, and many shrouded locks would be too bulky to fit well. My personal recommendation here would be a disc-type padlock like the Abus Diskus, which has a pretty flat, compact profile and a shackle that should fit most lockers. It offers very limited access to the shackle when locked, and it's shim-proof for the same reason -- not to mention it comes in at around $20, which is probably why it's a popular lock type in the self-storage industry.

For luggage locks, you tend to run into the same problem as with gym lockers -- it's kind of pointless to find a lock that's stronger than the door/container. But it's hard to recommend something specific without knowing more about the type of bag and where you're looking to protect it.

For hotel/motel room doors, there are a couple of popular lock types (both of which are only usable when you're in the room and require no hardware installation): door-frame jams that insert next to the door handle, and door-stop-type locks that use friction to keep the door from opening, bracing either from the handle/knob or the bottom of the door. I've pasted links for some representative examples of both types below.
