ABUS75IB/50 KD Marine Grade Chrome Plated Brass Padlock, Stainless Steel Shackle, Keyed Different

This is the most unusual and highest quality lock I have ever purchased. The lock is German designed and the key must first be registered with ABUS on their website using the code imprinted on the key head if the owner wishes to ever order a replacement. In any event, for security the key code should be registered immediately after purchase whether or not the purchaser wishes to order spare keys. Registration is free.The local locksmith will be unable to duplicate this key. It can be ordered only from ABUS for super security. You will have no worries about an unauthorized person going to a locksmith and making copies of THIS key. I know nothing about picking a lock. But I suspect this lock would be more difficult to pick than a normal padlock, which is easy to pick.Also, several purchasers have given this company one star ratings because the key did not "fit" the lock they purchased. This is what I thought was the problem with the lock I purchased. But just insert the key into the keyhole, turn the key one quarter of a turn, and open the shackle. The shackle does not pop open like a normal padlock. It just pulls/drops out after the key turns the cylinder one quarter of a turn. The key cannot be removed until the lock is again closed. I think you will like this unusual lock with its unusual key. Very highly recommended.

This lock is solid and heavy, has a quality feel and is much harder to pick than your average Master Lock, or any lock you can buy at this price for that matter. You can google for images of the type of key this lock uses, it is different from regular keys - this means thieves in US are likely unfamiliar with it and won't know how to pick it. this is also a dual ball bearing lock for resistance to shimming. it is also key retaining which i like.the one "weakness" of this lock is the shackle is stainless steel, not boron steel - in other words the shackle is designed more for weather resistance than cutting resistance.that said, for use with a gym locker the shackle is probably stronger than locker itself, so even if you get a boron shackle lock a person with bolt cutters would probably be able to cut the locker itself.anyway, this is just about a perfect padlock for use with pool lockers if you don't mind swimming with the key ( i don't ). for a gym locker you could consider an ABUS titalium which is lighter due to aluminum body, but is not marine grade.i have recently upgraded to ABLOY 330 which is 5 times the price of this lock and realistically, as i said, breaking the locker would still be just as easy. that said, the ABLOY 330 does feature a boron shackle, super massive body and 100% unpickable mechanism, and still fits my locker. i now use both locks because all my gear doesn't fit in one locker.now if you're using a padlock for application where the shackle doesn't need to fit into a small hole ( such as gym lockers ) then i would get a lock with a thicker shackle. all 8 mm shackles can be cut with bolt cutters, even the boron ones ( although it takes some muscle ). unfortunately gym and pool lockers won't accept shackles much larger than 8 mm. they probably do this so they can cut the locks off if somebody leaves the locks on overnight.

This padlock is just about the best product, of its type, on the market. The chromed body is manufactured for an adverse level environment and stands-up to coastal damp ocean humidity very well. The biggest and best plus is the lock mechanism. Its unique key and tumbler system is almost completely pick proof. That is why we use them on our US military facility outlying sites for best security. The mechanism uses varying depth tumbler recesses milled VERTICALLY into the thickness of the key, on both sides, rather than notches cut along one or both key edges. The vertical tumbler pins are set-up in a specific pattern so that the key is ambidextrous (you can flip it either way, right-side up or upside down, and insert it, to work). Because they are German-manufactured, you know the quality and engineering are built into the product. The per-item price is not really an issue considering the long term reliability and value being purchased. I purchased three for my own personal use and am very pleased how well they work, at all the locations. I fully recommend this product for any application where you would want locking capability without having to worry about the lock being picked or suffering from adverse weather. Bravo Arbus! Keep up the good work!!

Just received my order of two ABUS 75IB/50 Marine locks and I am impressed. Well-finished, zero defects, smooth key operation. Love the feature where the lock retains the key when the shackle is open, so you can't misplace the key. These locks, along with two ABUS cables, will be used to help secure two bicycles on a college campus, so the goal was to find an all-weather lock of sufficient size/strength with ball bearings for the shackle and a better-than-average key/cylinder. My primary concern is to deter/defeat the opportunistic thief, not the professional thief, so I am fairly satisfied this lock will do the job. Have read several reviews stating that some/many ABUS padlocks are now made in Chna, though neither of my locks nor the packaging identifies the country of origin; regardless, the product is well-made. The only drawback I can think of is being able to locate a locksmith capable of reproducing dimple-style keys, but that's my problem, not the manufacturer's. Good job, ABUS.
