My master lock 630D is stuck open! It swivels, but won't lift up to close it...any answers for that?

If your Master Lock 630D is stuck open and the handle won't lift up to close it, there are a few possible reasons for this issue. Here are some troubleshooting steps you can try: 1. Lubrication: Over time, dirt, dust, or rust can accumulate inside the lock mechanism, causing it to become stiff. Try applying a lubricant, such as WD-40 or a graphite-based lock lubricant, into the keyhole and around the shackle. Allow the lubricant to penetrate the lock for a few minutes, and then attempt to close the lock again. 2. Shackle Alignment: Sometimes, the shackle may not be aligned properly with the lock body, preventing it from closing. Gently wiggle or rotate the shackle while attempting to lift it up. This movement may help align the shackle and allow it to close properly. 3. Apply Pressure: While attempting to lift the shackle, apply gentle pressure on different parts of the lock body, such as the top or sides. Sometimes, applying slight pressure can help release any stuck components or align them correctly. 4. Tap the Lock: Tap the lock body with a rubber mallet or a similar non-damaging object. This gentle impact might help dislodge any internal components that are stuck, allowing the lock to close. 5. Seek Professional Help: If none of the above steps work, or if you are uncomfortable attempting to fix the lock yourself, it's best to consult a professional locksmith. They have the necessary tools and expertise to diagnose and resolve lock issues safely. Remember, it's important to be gentle when trying to fix a lock to avoid causing damage. If none of the troubleshooting steps work, consulting a professional locksmith is the best course of action.

My master spa legend series lsx 700 has been cycling more frequently and the temperature isn't maintaining. What could be the problem?

ive seen this happen before in an older spa , the owners were filling the spa with well water and it was high in minerals , this of course deposited on the heater surface and the heat after a point wouldn't transfer to the water any longer , eventually the heater gave out (overworked) and that's when I was called to have a look , that's what I found after taking it apart for a look inside !!

What's my combination

Each padlock has a different combination. If you lost yours, that's reall bad luck. Take it to a good locksmith, maybe he can find out. If pretends to charge you too much, get a new padlock

Locked myself out of my safe

Check to see if you stored the combination on the website: www.masterlockvault.com. If not, start from 0000 and go upwards to 9999, pressing the door release button after every try.

How do i unlock a master lock when it was lock upside down?

If it's a Master Lonk that the part that the key is inserted comes off and us put on upside down than the key may not fit in to unlock. If it's close, clamping the key part And cutting the rest off to get into loch to unlock. Good luck. (I've done this before)

Where do i store my combination

I am not aware of a "Lock Box" or "storage" capability on FixYa. If you want storage capability for free... Google free online storage.
  1. Googledrive.com
  2. box.com
  3. dropbox.com
  4. iCloud.com
  5. evernote.com
  6. bitcasa.com
These are just a few available that are very good.

I lost the combination to my speed dial master lock and it is in the locked position. How do I open it and create a new code?

It's not easy to fix this problem, because these locks do not shim open and it's not obvious how a person could figure out the old combo. I was able to loosen and remove the security screws, disassemble mine and repair it. They are very tricky to reassemble and it took me hours to find the spring that was out of position. The root problem was the lock did not clear when the shackle was pushed in. Until I figured that out, it would take up to 30 tries to get it open. The security screws are Metric - so you can replace them with regular screws until you get it working. If you do open the case, there are a lot of small parts inside, including a bunch of springs.

How do I get it back open when it won't open to the combination I gave it?

Make sure you push the shackle down firmly to clear the lock and try the combo again. It is possible to open it by trial and error, but not easy. I have removed the security screws and repaired one, but it was tricky to reassemble. The problem with mine was a spring that slipped out of position and the lock wouldn't reset correctly. There are a lot of parts inside, so chances of getting it to work correctly are not good unless you're really good with complex mechanisms and puzzles.
