Yif 4 numbered lock - got locked by mistake and I don't know combination

Few standard combination locks are machined to such a high degreee of precision that when the lock is put under strain one or more of the numbered rotating dials is not left a little loose while the other(s) become tight.

It is a matter of slowly turning the tight dial or barrel until it becomes loose. At this point the lock will move a little as long as it is kept under strain and one of the other numbered barrels that was previously a little loose will become tighter and so it is time to slowly turn this barrel and repeat until the lock releases.

Practice on something like a cheap cycle lock and you will discover the trick that is increasingly difficult as the quality of the lock improves.
It takes a light touch and lots of patience. So far I have even opened a quite expensive combination padlock this way but it relies on imperfect manufacture. It would be quite impossible to use the technique on a perfectly made combination lock.

To set a new combination:
The initial combination is set at the
factory to 0-0-0-0
1. Open the compartment door
2. Push the reset lever left and down.
The lever remains in this position
3. Rotate dials to your desired combination
4. Push the reset lever, up and right, back
to the original position
5. Close the key storage compartment door
6. Scramble the combination dials to lock
the door and conceal your combination
7. Close the shutter door

If this is an older masterlock with a serial number, you can fill out the form located here http://www.masterlock.com/pdfs/lost_combo_form.pdf
Read the below from masterlocks website: Due to increased security concerns nationwide, Master Lock recognizes the heightened need for additional safety measures. We no longer provide lock combinations in response to phone, fax, or email requests. Please follow the procedure outlined below to obtain the combination to your lock and submit your request to:
Master Lock Warehouse
1600 W. La Quinta Rd
Suite/WHSE # 1
Nogales, AZ 85621Procedure:

• Print out the Lost Combination Form from a printer friendly page, or download the PDF file.
• Have your Lost Combination Form notarized by a Notary Public to prove that you are the owner of the lock (you can include up to 6 combinations on one notarized form).
  
  • Note: Inmates at a correctional facility - in addition to the lost combination form, you must submit your request on official prison letterhead. In lieu of notarization, the form must be signed by a prison official.
• Photocopy the serial number on the back case of your combination lock. This copy MUST clearly show that the lock is not attached to anything. Be sure to hand write the serial number on the photocopy.
• Mail the original completed, notarized Lost Combination Form and the photocopy of the back of your lock to the address above.

Note: It will take approximately 4 to 6 weeks to process your request for a combination.

Note: If the form is not fully completed and notarized with a raised seal or rubber stamped seal, or if the serial number is not legible on the photocopy, your request will not be honored. Master Lock does not reimburse for any Notary fees.

Try the default lock codes. The typical lock codes for a phone are 0000, 1234, and most commonly, the last 4 digits of your phone number. If all 3 don't work, try to take the phone to your service provider's store and they might be able to reset it for you.

It would appear that you made a mistake in setting your new combination on your Master Lock 5400d and did not register the combination at Masterlockvault.com. The only way to open your lock is by using the correct combination. There is no other way. Most mistakes are normally one or two digits out, so you may wish to try variations on what you thought you set.

Apart from that you can either try every possible combination or you will need to contact the manufacturer. But they cannot assist you if the lock does not have a serial number (they recently stopped applying serial numbers for greater security) and they will not assist if the lock is already secured to anything. There are a number of other hurdles as well, click here for details. Given that they state that you will have to wait four to six weeks for an answer, it's going to be far quicker to just try every possible combination.
