User questions & answers

Question: I would like a blue Speed Dial Masterlock. The description indicates that the colors are selected randomly at the time of shipment
Answer: If you place your order before 2pm, send us an email with your order number and I'll go back to the warehouse and make sure you get the blue one. Thanks for choosing Home Network Supply!
Question: Does this only do four directions? Or can it do more? I need one that allows the combination to be five
Answer: If I understand your question: it only allows four directions (up, down, left, right.) But what I think you're getting at is how many steps you can add. In that case, you can enter pretty much as many steps as your like (Gismodo used 30 steps successfully). Personally, I've set mine for eight, giving 1:65,563 odds (and that's only if a stranger knew that I had used eight, which they wouldn't.) If you want to use five, that's fine, and will give the odds of 1:1024 (assuming it was publicly known that you only used five steps.)
Question: My granddaughter is legally blind. Do you have a blue padlock? The reason I ask is because she can't see most colors on white. Same problem with black
Answer: In my opinion, the Blue is the worst for visibility. The stickers are dark blue with black text - almost impossible for me to read except under a bright light. However, the great thing about these locks is that once you remember the sequence you don't have to be able to read the sticker labels. Also you can choose a simple sequence or a more difficult one. For my work locks I use an eight movement sequence. For my son's lock I use a four movement sequence. I love these locks.
Question: How many combinations are possible? (i.e., how many stops for each wheel inside?) 10 stops/wheel would be like a 4-digit combination lock. Is that so
Answer: Although there are infinitely many sequences you can set as the combination, the lock has only 7,500 internal positions, not counting the reset position. This means that if you set a particular sequence to open the lock, there are infinitely many other sequences that will also open the lock. For example, if you set the combination to LURL (left-up-right-left), the lock will also open with the sequence RLL. Some people consider this a bug or defect, I think it is simply a technical aspect that is not disclosed to consumers because the mechanical explanation is too complex for the average consumer. This technical paper by a lock collector in the Netherlands has a more detailed mathematical explanation https://toool.nl/images/e/e5/The_New_Master_Lock_Combination_Padlock_V2.0.pdf . One of the interesting takeaways from this paper is that every sequence longer than 11 moves is equivalent to some sequence of 11 or fewer moves. So it does not make any sense to torture yourself to remember a 12-move or 13-move sequence. For instance, UUUURRRRDDDDD is the same as LLURD.

Product features

Set Your Own Directional Combination Lock

Set your own directional combination lock for speed and easy combination recall. Combination can be reset to any number of movements in any sequence. Lock can be opened one-handed without looking for ease of use.

Troubleshooting Help

Sometimes, step 3 of the instructions is overlooked. Try entering your old and new combinations in one long string of movements.

Enhanced Security

Shimming is defined as violating a lock by inserting a foreign object into the latch mechanism. Master Lock padlocks feature technology specifically designed to protect the latch assembly so there is no target for the shim tool to hit making the lock more difficult to defeat.

Question: What is the diameter of the end you can thread thru something? I need something that will thread thru a 7/8" hole
Answer: The end is 1.08". It is too large to fit through a 7/8" hole.
Question: Could you use one lock for two bikes while they’re on a trunk mounted bike rack
Answer: Absolutely! They just need to have cable-accessible frame points within about two feet of each other. This lock will keep the typical petty criminal from walking off with the bike, but if a hard-core crook brings a monster set of bolt cutters or a cutting torch with him/her, they will get them. HTH.

Question: Is the combination required to close the lock

Answer: The key phrase in the description in "Keyed Differently" so in this case you will get 6 different key and lock sets.
Question: After you set the combination are you able to change it at any time
Answer: I don't know, but I know it fits my pelican gun case
Question: How do you reset the combination
Answer: It will fit, but this is a relatively low-security lock. It's fine if you have nothing valuable or important in the locker (such as textbooks or electronics), but there are much better locks (eg. Master Lock 185d) that will fit a standard school locker.

User questions & answers

Question: I am comparing to the noke What is the ml made of looks plastic not steel?, also how well does the tamper alert work?is it water proof
Answer: The answers below are incorrect. You can program a 4-10 digit code. There is a preset, but it can be deleted. I forget how many codes you can have but it is definitely more than one.
Question: Would this be a good gym lock
Answer: yes, when you exit the door, there is an exit button you push when you're on the outside of the door you turn the deadbolt push enter only and it is locked. this is my third key code Lock entry, and by far the BEST.
Question: Can you do customized sharing? For example, if I control the lock, can I share the key with someone else for single or multiple use
Answer: I'm using indoors. I don't think it would be recommended for outside use.
Question: How long does the battery charge last in standby mode
Answer: If you're asking if this comes with a key, the answer is yes. If you're asking what composite material is used to manufacture the key, I haven't the faintest idea. The Master Lock key has a large, what I would describe as, bulbous head, and a standard key 'shaft', approximately 2 inches long. It is the type of key which can be duplicated at your local hardware store.

User questions & answers

Question: Lost the change key -- how to reset the combo without it
Answer: you can just use a small screwdriver to push in and change the combo while doing so. The Key really just holds down the bar inside for you.
Question: What's the diameter of the shackle? I need to make sure it can fit through a hole in a security box
Answer: 5/16"http://www.allpadlocks.com/cgi-bin/ez-catalog/product_images.cgi?account=X380790;product_id=M178;image=images%2Fcatalog%2F178sketch.jpg
Question: Is it for outdoor use
Answer: It hasn't fared well for us. We have an older one which held up for about 3 years before needing to be replaced. The lifetime warranty allows you only one replacement, so it really isn't a lifetime warranty at all. If you live near the beach, consider yourself lucky if it works for 2-3 years. That said, it is for outdoor use, just expect to lubricate frequently especially after rain or if you live near saltwater.
Question: Does this lock have any harmful chemicals Prop
Answer: Don’t put it in your drink or cook with it, if it mixes into your drink or food it could make you sick but I believe the report said you’d have to do that 834 times to have a negative affect on you. But on a side note I read just the paper from the Prop 65 rule could make you violently sick if you eat all the paper in just one setting.

Question: Is it for outdoor use
Answer: I believe they give a year. We had a crazy rain/wind storm and water got into mine. They walked through my property management company on how to "fix" it, which was I think hair drying it out, and then "caulking" it to make it water tight again.
