PACLOCK's 90A-PRO Padlock, 1/4" Diameter Hard. Stainless Steel Shackle, 1-3/16" Tall, High Performance 7-Pin Cylinder w/ 1 Key, Keyed Differently, Blue

I bought this lock mainly to complete Paclock’s “200k challenge”, where you record yourself picking and gutting the lock and they reward you with a patch and certificate. It arrived today and I’ve since picked it open 3 times. It gives excellent feedback and is super fun to pick. Its actual difficulty level is debatable though. 7 pins and 200k key combinations is useful against certain attacks but a good picker will get it right open, and without getting into minutiae I’ll say there’s a very certain method to getting it open quick, and now I’m halfway tempted to buy another one and test that theory. I wonder how much of Paclock’s sales on this come from people like me anyway. My goal is to keep my picking and gutting video under 5 minutes and that won’t be too difficult. I prepared myself for this with a tricky American Lock 1100 and a German Abus 72/40 and I was well prepared. Now onto real life applications, this is a super heavy duty lock and the 7 pin keyway cannot be picked by anyone without some pretty significant skill and experience with security pins. The weak point on any padlock like this is the shackle and the best part about this is that the shackle is replaceable. Small consolation if it gets cut off and your stuff gets stolen, but at least you probably won’t lose the lock. Finally, these come with stainless steel pins and if you get one with a stainless shackle it just will not rust. And finally it’s a quality American made product and operating it is just satisfying, whether you’re turning it with a key or a tension bar. Guess it’s time to get recording! Got a patch and a blue belt waiting for me.

If you want a truly pick resistant lock, this is for you. It has a 7 pin keyway, full of security pins. I bought this for locksport. But if I need a lock to secure my stuff, this is what I would use. Love the color too!!

It's an industry standard for a reason, tight tolerances, seven Pyne total six of which are security pins (alternating spool and serrated and standard in the seventh slot), no spring resistance on the core: picking one open, you have to know what you're doing and be hone in your skills. I'd put it ahead of dozens of locks costing two or three times as much by other companies. Place it comes in a whole bunch of really cool colors so that's super cute and fun. Whether it's customized for your personality or color-coded locking systems, you can go nuts get a whole rainbow of the paclock pro 90 a's.

Well, I bought this for locksport practice and have yet to give it a try. I'm quite sure it would be sufficient to safeguard your goods.

Anyone who has watched the Lock Picking Lawyer on YouTube knows that Paclock makes good products, and that they're engaged with and responsive to their customers. Because of that, I bought several of these in the standard size. When I wanted to get some of this model of lock (90A-Pro, keyed alike) with a longer shackle (2"), I called them. They told me to place the order on Amazon, then give them the order number, so that they could adjust it in their system. I did. Unfortunately, the locks that were delivered had the standard shackle length. I called back to their customer service line and (as before) very quickly got a live, pleasant, helpful person, who apologized for the error, and gave me two options: Paclock could provide a longer shackle and I could install it, or they could mail me two new locks with the appropriate length shackle. I have some ability with a screwdriver, but I'm not confident taking locks apart, and don't have the tiny screwdrivers needed for the set screws. I asked them if they would mind making the shackle length an extra 1/2" longer, which they graciously agreed to do. A few days later, I had my 2 new (and longer!) keyed-alike 90A-Pro locks. They're perfect! I know a lot of companies get bad reviews because people are more likely to complain than praise on a public forum, and unfortunately that leads to the impression that nobody has quality products or service anymore. Paclock excels at both quality and service. If you want great locks and great service, buy from Paclock.

Well made, easy to disassemble. Not an easy lock to pick or rake quickly. Terrible feedback and crunchy pin movement. Core has a little bit of play within the padlock, which adds to the sloppy feel. I can open mine easily in under a minute, but that’s only because I’ve been practicing on this lock for a couple weeks and have memorized the binding order. I would use this as a gym locker lock and feel pretty confident about it. Ultimately if someone wants in, they’ll just cut it, but if someone relatively unskilled were raking and bypassing locks quietly, they’d probably end up skipping this one with how long it would take them to defeat it. I both love and hate this padlock, and will probably buy more Paclock products in the future. Good stuff.

Lightweight aluminum body and hardened shackle. No sense lugging around two pounds to lock us ones belongings at the gym. Like most padlocks, I'm sure the shackle could be cut with bolt cutters or an angle grinder for certain. But that kind of activity is most likely going to get noticed at a gym with a reasonable amount of traffic. Where the PacLock 90A shines is it's seven pin core and resistance to shimming and bypass methods the majority of padlocks on the market are vulnerable too. Many padlocks contain a four pin core, larger masterlocks and padlocks will usually contain five and that's pretty standard across the market. The vast majority of those are pinned with standard key and driver pins. Many can be zipped open in seconds and the rest picked or raked open in a minute or less by any novice lockpicker (if not combed over or bypassed with no picking at all). The PacLock 90A has seven pin stacks and all but one contained at least one security pin per stack, some both. A mixture of serrated and spool/mushroom pins. All locks are pickable, but the 90A Pro is going to keep even an experienced picker busy for quite some time, most likely longer than your workout. In reality, a thief is likely either going to become quickly frustrated or see your PacLock and move along to easier targets. Which is exactly what you want from a lock on something like your gym locker. They offer better locks for outdoor use and securing things in places where a thief may have more time and privacy, places calling for something a little more heavy duty. But this is perfect for lockers at work or the gym and such. Ideal, in fact.

I bought this lock for two reasons, the seven pin cylinder and it's purple. The purple is great, the seven pin cylinder, not so much. The pinning. Of the seven pins, this is how they go. (I used a Weiser gauge so Paclock's number may be different) 6,7,8,8,6,6,8. REALLY?? You could rake this lock in two seconds. Also, the tolerances in the machining is quite lax which makes for sloppy function. The first time I opened the lock, I had to fight to key the key back out and then work it for several minutes to keep it from jamming. And there is only one key. Why not two or more like every other lock in the world. UPDATE - I tore the lock down and the cylinder is quite nice and the overall build is good. After some excessive in-and-out with the key, it's much smoother now. It still looses one star for the pinning and single key.

Look is very well built and finished, very secure 7 pin core. Family-owned business and made in USA. Highly recommended, don't waste your time with MasterLocks, buy this instead.
