I have a dudley lock with a serial Number I would like the combination numbers AN546451

The key should open the safe in any circumstances.

All safes of this type have a 4 number combination.

They are very insecure and can be open using a Rare Earth Puck Magnet. Then you can remove the batteries, and reset the code.

I think you have given us the Serial Number not the Model Number?

For an electronic safe, you can use a rare earth magnet to draw the locking arm.

No, no, no, no. That won't work. Otherwise, anyone could get the serial number, get your combination, and open your lock.

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.

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.

Make sure you are inserting key so the round hump on key matches red dot on lock, and turn key clockwise.

If that doesn't fix it, SentrySafe's support number is 1-800-828-1438.

I would think they can confirm the combination from your serial number. They probably won't give you the combination without a notarized letter, but if you have the right combination for that serial number safe, they may confirm that you are entering the right combination.

Be aware the 4 number combination V260's are changeable and if you HAVE changed it, you are on your own, they can't help you. The 3 number combinations are not changeable.
