Upon receiving the luggage you've just bought, you realised that the lock has a keyhole but the key is nowhere to be found!
1. Where is the key to the lock?
If the number lock looks similar to any lock in the picture below, with a red diamond logo, it is a TSA (Travel Sentry® Approved) lock. There is NO key to the lock, as the key is held ONLY by the immigration customs, for them to check the luggage contents without damaging the number lock. It is a safety regulation imposed by United States and Canada for all inbound/outbound/transit passengers to have their luggage locked either by TSA lock or TSA padlock.
Different types of TSA locks
2. Which countries require TSA locks?
For now, only visitors to U.S. and Canada need to adhere to this safety regulation.

3. How do I reset / change the passcode?
The default passcode to unlock is '0-0-0'.
a) With the number combination in the unlocked position, locate a small round button at the side of the lock. Using the sharp tip of a pen, push the round button in (it should remain depressed).
b) Next, turn the number dials to your desired combination.
c) Then push the unlock latch and the small round button will pop out with a 'click' sound. The new passcode is now set! 
4. How about Safe Skies locks?
It is an equal substitute for the TSA (red diamond logo) lock, and carries a red torch logo. It also does not have a key. Both TSA and Safe Skies locks are accepted at U.S. and Canadian customs.
