I have a brand new Travel Pro suitcase. I want to set the combination lock. How?


Some Travelpro bags come with an external lock upon purchase included in the user information package with the user manual and the add-a-bag strap or hook. This external lock can be looped through the zipper openings to secure your bag. To set the lock to your combination, follow these steps.
  1. External Travelpro Lock:
  2. Unlock the mechanism by pulling up on the metal lock rod. The 3 dial combination must be set to (0-0-0) factory combination if new, or the existing combination if used to unlock.
  3. Once released, rotate the lock rod to align with the notch of the dials, usually perpendicular to the long side, or about 90 degrees from its lock position.
  4. Select a new 3 digit combination.
  5. Press down the lock rod all the way and hold in that position while you turn the dials to reflect your new combination. NOTE**The lock rod must be held down all the way until you have your 3 digit combination in place, otherwise an unknown combination will be set while you adjust the dials.**
  6. Once your new combination is in place, release the lock rod. This sets the new combination.
  7. Return the lock rod back to the locking position and double check that your new combination does lock and unlock.
  8. Scramble the dials in order to keep your luggage safe and secure.

I have bought a used red head safe. It's open but I can't get it to close. Also, I don't have a combination for it and I'd like to make up my own. Can you help me?


Most likely it will not close because the lock has been activated while the door was open. Probably need to take it to a locksmith.

How to change the 3 digit code of my samsonite ?


Luggage manufacturer Samsonite offers a variety of business, personal, travel products and accessories. Many Samsonite pieces such as attaches and other bags include a three-digit, built-in combination lock. When purchased, the locks are set on a factory default combination that you can change as often as you wish.

STEP 1
Turn the number dials to the previously set combination, or to "0-0-0", the factory default combination for Samsonite luggage.

STEP 2
Locate the reset button, usually placed to the side of the combination dials.

STEP 3
Press the reset button and hold it while rotating the number dials to the desired combination. Set this to a sequence easy for you to remember but hard for others to figure out.

STEP 4
Release the reset button after you set the numbers to the new combination.

STEP 5
Test the combination by turning the dials to the new code to open the lock. If the combination does not open the lock, repeat Steps 1 through 4 and test the lock again. If you still can't open the lock, contact Samsonite Customer Service at 800-765-2247.

How many different number combinations are there using the numbers 1 1 0 8


I assume you mean different decimal numbers, using those four digits, right? If so, the answer can be reached two ways.

One way is to actually build up the model by changing one digit at a time, then moving a decimal place. Thus: 1108, 1101, 1100 then 1118, 1111, 1110 then 1188, 1181, 1180 and so on. You will count 81 combinations.

Since those three different digits can be placed in four decimal places, the answer in another way is: 3*3*3*3=81.

If you prefer to employ your own code, you can
program the safe to open using a 5-digit user code
of your choice.
3. User pin

to the safe, you can program a 5-digit user pin that
can later be erased.

What are all the possible combinations of 8 and 0 using a 4 digit code?


"Combination" implies that the order doesn't matter. In that case there are five combinations: 0000, 0008, 0088, 0888, and 8888.

If the order does matter then there are sixteen permutations: 0000, 0008, 0080, 0088, 0800, 0808, 0880, 0888, 8000, 8008, 8080, 8088, 8800, 8808, 8880, and 8888.

Cannot unlock my husbands tsa lock we are in argentina


To set/reset combination on TSA Cable Lock

TSA Cable Locks come preset from the factory to 0-0-0. Set the combination to 0-0-0 or your already chosen combination. if different than 0-0-0. To set the combination, use a pointed device such as a pen to press in on B. While pressing on B (do not release B until combination is set), pick your 3 digit combination.

Once all 3 dials are set to the combination you want, release B. Your TSA Cable lock Is now set to your combination. TSA Lock will NOT be locked at this new combination - turn one or more dials and your lock will be locked. To unlock, follow instructions above.

Please make sure to remember your combination!

Combinations and Permutations


You can enter combinations and permutations.

If the order of the selection matters (ie. 1st, 2nd, and 3rd place out of 40 contestants) use permutation. Enter:

40{shift}{nPr}3 and then [=] for your answer set (=59280 possible ways).

IF order doesn not matter (ie. a team of 3 from 40 possible members) then it is a combination. Do the same as above, but substitute {nCr} for {nPr}. (= 9880 possible ways).

For your question: a three-digit set, selecting from 0-9. There is no specified order, it is a combination. The total n=10 (there are 10 digits in the range 0-9) and you are selecting 3.

so.... 10[nCr]3 with give the number of possible combinations.
