If you own a keychain size mini light swiss army knife by Victorinox, at some point your battery for the mini light feature will eventually run out. By "mini light", I mean a pocketknife that is 58 mm (about 2 1/4 inches) long when closed. It is simple to change and will allow you to enjoy your lighted swiss army knife and all its functions for years to come.
Battery changing steps:
Hold the mini light knife in your left hand with the red/white cross and shield logo facing up. On the right side of the top scale you should see a small hole - it is on the side so you'll have to slightly rotate the knife in your hand to see it. It is towards the lower end of the scale on the right. Take a paperclip and bend it so you can use it to poke into this hole. Carefully poke into this hole and push out the old battery. The old battery and a little plastic piece the same color as the knife scale will drop into your hand. Be careful not to lose that little plastic piece! Insert a new battery with the positive side facing up. Put the little plastic piece back into the side of the knife to hide/cover the battery you just put in.
The Victorinox Swiss Army Brands part number for the battery you need is 22068. The battery is a Panasonic CR 1025, 3V. Your new battery should be good for approximately 2 to 2 1/2 years under normal operation of your swiss lite knife. Your handy little swisslite should be as good as new.
