In fact, it is so important that most of this information may not be specific enough for your situation. However, this is the best combination of general and specific information that can be combined.

What is the combination lock installed?

Combination locks are used in a variety of different devices. The place where the lock is used will really tell you a bit about it. For example, it can help you reduce the proper method to change the combination. Here are some things that are important to change the combination locks on the following devices.

1. Change safe combination

The most difficult method to change a combination lock is likely to be found when it comes to safe combinations. The determining factor for the difficulty will be whether or not the safe combination is digital or not.

Mechanical dial locks have combination change protocols that are more varied and often significantly more complex than those of secure electronic combinations. Unless the safe is already open, a combination of a lost safe means that you will need assistance to open the safe. This is one of the many situations in which you will need a locksmith to open your safe.

Search your user manual for a section such as "change combination" or "how to change the combination lock". If you don't have your user manual, you can find one online. For a good general / specific idea, read on.

1. Change the safe combination: manual dialing: if you have obtained your safe from one of the best safe companies, you probably have a Sargent and Greenleaf manual mechanical dial. The process of how to change a secure combination can be a bit complicated, but you can do it yourself as long as you can find your change key.

• Open your safe.
• With the safe door open, manipulate the dial using the existing combination. However, you will move the numbers to the exchange mark (the mark to the left of the 12 o'clock mark used to open the safe).
• Leave the dialing secure on the last number of your combination.
• Insert your shift key into the keyhole on the inside of the safe door.
• Turn the safety key and do not overtighten the key in the keyway.
• Mark your new combination with the change mark, use the proper rotation process that you would use to open the safe.
• Leave the safe dial on the last number of your new combination.
• Turn and remove the change key.
• Try the new combination several times while the door is still open.
• You can read more about this type of blocking here. If you have an old or old safe, it may require different protocols to change the secure combination. The combination change process is probably a variation of the process described above. However, make sure you know what you are doing or consult a professional before attempting this process.

2. Change the secure combination: Digital: For digital locks, they will have a reset button or dialing procedure, which moves the digital keyboard to programming mode. Without changing the digital combination lock of the safe to programming mode, the lock will only register codes as attempts to open the safe.

If you do not know the particular protocol that your secure digital combination lock uses to enter programming mode, call a locksmith or search for the user's guide. Once you have the safe in programming mode, most digital locks will need the existing code to use it before you can change the safe combination.

Most likely, it has an S&G lock (Sargent and Greenleaf) because most of the safe manufacturers use this brand. The combination change protocol for S&G digital security locks is as follows:

• When the door is open, press "7", then "4", then "*" (the asterisk button).
• The lock will move to programming mode, but you must still insert the current secure combination and then press "#" (the number button).
• Wait until you have heard five different beeps.
• Indicate that you want to change the safe combination by pressing “1”, then “*” (the asterisk button).
• Enter the new code, then press "#" (the numeral button).
• Wait until you have heard three different beeps.
• Insert the new code a second time, then press "#" (the number button).
• Wait until you have heard three different beeps, this will indicate that both the first code and the second code match.
• The digital lock will now be out of programming mode.
• Before closing your safe, verify that the new combination works as expected.
• You can see more available literature on Sargent and Greenleaf electronic locks, here. For other less complicated electronic security locks, to change a secure combination, you can open the safe, press "0" six times, enter the current code and then enter the new combination twice.
• When none of these processes are working, call a locksmith.

2. Change lock combination

Not all combination locks can change their combination. In the case of modern combination locks, many companies are incorporating this feature into new product designs, but for older combination locks, you are stuck with the combination you came with.

Again, this will vary. To find out if your lock is the exception to the rule, look for the brand and model number. If you don't have the model number, you can find it online by searching for images or product lists of combined locks that have the same brand.

When you can change the combination in your lock, it is probably a fairly simple process. Because these locks are made for the mass market, designers want the combination changes to be simple (because that is what most consumers want). This impairs the security of the padlock, so you don't see combination locks on the list of the best locks of all time.

To know whether or not you can change a combination in your lock, much less what the procedure is, use the following process.

• Open your preferred search engine.
• Enter the information you have about your lock.
• Manufacturer's Name
• Combination style.
• Model number.
• Any other information you have about the lock.
• Look for a video or official documentation.
• Make sure that you can visually confirm that the lock you are talking about is the same model as yours.
• Try the method.
• Try not to break the lock while trying to change the combination. Most likely, it is cheap to replace it, but you don't want to leave what you are protecting more vulnerable than it already is.

How to change the combination door locks is not restricted to this method. You are likely to find this type of combination change protocol, but not necessarily. It is impossible to list the exceptions to this rule, but if you discover that this is not the way to change the combination locks on your door, call a locksmith.

2. Change the combination lock: digital: If the digital combination door lock is a smart lock, there is likely to be a function in your application that allows you to change the combination. When you have a basic digital combination lock, you need to find your reset protocol.

For many Schlage digital combination door locks, this will be a code found in the lock manual and / or the interior hardware of the lock. The programming code can also be reset. The complicated thing about these locks is how many programming functions there are. It is easy to reprogram the lock in a way that was not intended.

The Kwikset SmartCode locks become a bit more complicated and force you to remove the battery and hold the reset button while reinserting the batteries. You have to wait for the lights to flash. Press the program button again and then follow the installation protocol, because you have returned the lock to its factory settings.

If you have difficulty changing the door combination locks, try to find information about the manufacturer and the model of the lock. If you cannot or feel overwhelmed at some time during the process, contact a local locksmith.

4. Change briefcase lock combination

Briefcases often use wheel combination locks, where the numbered wheel will rotate independently. If you don't have the current combination, don't worry, because this combination lock style only provides the illusion of security. You may worry that this type of lock is unsafe once you reopen it.

Decode the combination by inserting a thickness gauge to discern the pattern, or keep the pressure on the release mechanism and turn each wheel to find which number is giving the greatest resistance. If these decoding methods are too new for you, it is probably best to call a locksmith.

When you get the briefcase combination, follow these steps:

• Pull the lock release and hold the lock latch in the unlocked position.
• While maintaining pressure to keep the lock open, turn the wheels to the new combination.
• Relieve the pressure and allow the latch to return to its fully extended position.
• While the briefcase is open and the latch is extended, check if the new combination works.
• Close the case.

5. Change locker combination

The mechanical dial combination locks that are integrated into the lockers are designed to make changing the combination locks simple and fast. Because these blockages are used in schools and work environments, it is very important that you keep detailed records of these changes.

This information does not apply to locker locks where people bring their own locks. For information on how to change locks on removable cabinets (which are padlocks), go to section 2 (Change padlock combination).

The most popular type of integrated combination lock are those manufactured by Master Lock. It is true that Master Lock is one of the low quality security brands, but they work well for the purpose of locking the lockers (which are insecure by their nature).

There are two main combination change processes for the Master Lock built-in lock locks. The first (for older models) requires that:

• Insert the change key and turn clockwise (right) until it stops.
• Move the dial to "0".
• Press a button on the back of the lock hardware.
• While pressing the button, move the dial to the left (left), two marks (up to "48").
• Release the button.
• Turn the key back to remove it.
• Turn the dial to the right (right), until you hear a click.
• Verify that the new combination is the next combination in the series.
• For more modern Master Lock built-in lock locks, it is much faster to change combinations.
• Insert the change key and turn counterclockwise (left), ¼ turn.
• Turn the dial two clicks counterclockwise (left).
• Turn the key back.
• Turn the dial until you hear a click.

Remove the key and check if the combination has changed to the next in the series.

If you do not have a change code, be sure to call a locksmith. This process should not be handled without a change key. Choosing the lock cylinder is not a reliable way to continue changing this style of locks.
