Re: Need help resetting a masterlock620d

Sorry this is a bit late and it might not work on masters but the locks look the same as the ones that I have.

To open them, hook your index finger into the shackle then using your thumb and middle finger, pull on the shackle, HARD,

Turn each wheel and if it is like the ones that I have the wheel will stick on the correct number. Do to each wheel.

Once the first are set the shackle will just pop open when the third wheel hits the correct number.

It does not matter which order that wheels are set - start top, start bottom, random.

To be really flash. After you get the feel (correct tension on shackle and feel of the wheels) you can do it behind your back.

Note. I have not tried the Master version of these locks but all other versions I've seen have been cracked using the same method plus they probably all come out of the same factory.

BTW. the factory default is 000

Cheers.

It works on Master locks, too.

only 3 wheels?

step 1. sit on couch
step 2. dial numbers for 15 minutes
step 3. lock opens
step 4. write down combination
