I want to change my Master Lock combination

I have tried many websites asking how I can change my combination but nothing worked. I want to change it so it would be easier for me to have the same combination as my locker at school.

Some masterlock combination locks are changeable and some are not. Do you know which model you have? If so, you can call your local masterlock distributor, such as a hardware store and ask. They should be able to help you. good luck

I got the master lock speed dial combination lock but forgot my combination and it won't open. can somebody please tell me if i can reset the password?


1. Contact Masterlock.com and fill out the form, get it notarized and send it in for the combination to unlock it based on the S/N which is on the lock.(http://www.masterlock.com/faq/LostCombinations/). Good luck on this since Masterlock will end up finding something that will prevent them from giving you the combination. Its quite frustrating and NOT worth the trouble.

2. Go to home depot. Buy a 24in bolt cutter ($22) cut the stem of the lock. and replace with a new lock that you can buy from home depot for $ 29.00. If you have a key that is inside the lock box that you really need, You will now need to drill out the combinations piece by piece and the door will pop open or send the lock back to Masterlock. They will retrieve the key for you and send it back.

How do you open a master lock model 5400d if you forgot the combination


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.

I have a 175D combination lock. I recently changed the combination # and it worked in the morning and now does not close. Iv'e tried changing the combination but mstill won't close?


I hate to say this, because Masterlock makes a fine product: It sounds like something inside the wheel assembly is broken. If it's still under warranty, send it to Mster Lock for a replacement. If not, replace it with a Corbin Sesame. Corbin originated the design, and they've been making the lock for several decades, now.

The combination our Master Lock Co Combination Lock Box Part # 5401D was changed by accident. How do we find the combination to open the box?


No joke... trial and error... its not going to be fun, but work out a system so you don't cover the same number twice.

If the lock has been forced or tampered with to cause this problem, then a replacement is needed.

Hope this helps
