Master Lock

Postby mm24_7 » 30 Sep 2003 21:05

I have a Master lock but not the standard combination lock with the dial on the front. Mine is the kind that is gold and along the bottom of the lock there are four wheels that each are numbered from 0-9. If someone would explain to me how to open this I would be very happy. Please let me know.

ok on the bottom try to pry the whole plate out. If u use a small screwdriver, it should not be too hard. once u have it open, u can look for a 4 pronged fork, and see what number will allow it to come down all the way.

another way is to turn the dials REALLY REALLY FAST and you will eventually hit the right combo. Sounds stupid, but it actually works. I used it myself before.

Those type of Master locks also have a hole in the side where a "key" can be inserted to set the combination. Take a good light, shine it in there and have a peek while slowy turning each wheel.

This will give you a good idea on how it works.

If I recall, you can use a broken pick or some other device with the slightest bend on the tip to reach in and "feel" the notch where the correct number will land.

Line these up, and the lock should open.

I'll check into them more and post with updates if I find an easier method.

go to this website. it gives a good description on how to bypass the master lock and other types like it. the tool that is used is easily made out of some very thin feeler gauge. i made mine out of 0.20 or 0.28 i think. hope this info helps. :)

I can't find the link. But I watched someone open one of those by pressing in the shackle, stuffing a normal hook pick into the gap above one of the wheels and releasing the shackle.

here i copied the instructions off the website. its easier to understand if you can see the pictures with it tho. the knife itself looks about 2 inches long and approx 1/4 inch wide, with some kind of plastic handle on it. here is the url again, maybe i didnt copy the whole thing

http://www.peterson-international.com/k ... ctions.htm

The Peterson MiniKnife promotes finer steel than what is currently on the market. The steel will allow more techniques to be applied to your projects without folding the blade. You will be able to feel what is happening inside of the lock better and to manipulate the blade to the location needed to create a clean and fast opening procedure. The Peterson MiniKnife will open wheeled combination padlocks like the PrestoÃ’ series, the Corbin, the Sesamee, and the MasterÃ’. You can also open GM Combination Glove Box Locks as well as other direct drive luggage combination locks.
MasterÃ’ and Sesamee: Both of these locks are of similar construction. They both have a locking plate with fingers and they both have combination wheels with collars that discourage entry of a tool such as the MiniKnife.
Opening the MasterÃ’ and Sesamee: These two padlocks can be opened by the same process. You want to insert the Peterson MiniKnife not quite halfway into the MasterÃ’ #175 beside either side of wheel number three. Go into the lock above the centerline and feel your way underneath the locking plate. Remember that there is a collar on the wheels that will discourage entry. You can slightly bend the tip of the MiniKnife with your fingertips if needed. With the Sesamee lock, you will want to insert the blade beside the second wheel and go nearly all of the way in with the blade. You are trying to get under the locking plate to move the locking plate towards the side of the lock body. Pushing in on the shackle will help you to maneuver under the plate. By exploiting the locking plate at its weakest point, where the spring in the lock is trying to push the locking plate towards the center of the lock, you will be lifting this plate while at the same time pushing in on the shackle. You will then release the shackle while maintaining the tension against the locking plate.
Opening the Presto 2620: Instead of lifting the MiniKnife’s tip as you did above with the Master and Sesamee, you will be pushing on the blade to open the 2620. Curve the tip of the blade so that as contact is made with the locking plate, the blade tip will be half way between tumbler two and three. You will bend the tip and insert the tip of the blade so that it is pointing left as you enter the left side of the third tumbler wheel. Feel the spring pressure of the locking plate and continue to push in while pushing in and releasing the shackle. The shackle action will be the same as on the Master and Sesamee.
Opening the Presto 2470 and other direct drive combination locks: Direct drive means that the combination must be known for the tumblers to release the shackle or locking bolt. There is not a bypass (locking plate and locking plate tab or bar is not present) as in the other locks mentioned above. To accomplish the opening you will place the end of the MiniKnife to the left side each of the combination wheels. You will then rotate each wheel in turn finding the indention on the spindle beside each wheel. The indention on each wheel is the opening indicator. You will line the indentions as if you were dialing the combination to the opening index (that is between the arrows on the side of the padlock). With the indentions between the arrows, subtract two numbers from each wheel. This should be the opening combination. If the padlock does not open when the shackle is pulled, continue to rotate all of the combination wheels subtracting one more number from each wheel until a full rotation has been completed testing for shackle opening with each new setting. If the effort still fails, then an error in finding the indentations may have occurred and you will need to try the procedure again. Reference the photos for a better understanding.

Master lock video

Postby Eagerpicker » 7 Nov 2003 15:21

Take a look at the first media clip on www.picklocks.com. It shows a Master lock that fits your description being opened in about 2 seconds.

IIRC the way I primarily deal with these is to take a dremel and drill holes next to the wheels, I dont remember witch side but the wheels will have a flat spot next to them because of the combination change feature.... find all 4 flat spots with a piece of wire inserted into your poke holes and then turn them all together one by one until you can open the lock.
