Green laser broke

[Ut2442]

I have a 50mW green laser somebody had dropped it and I think it knocked the leads off from the push button.
Does anybody know how to take apart the back part of a laser to access the push button? I will upload photos when I get on my computer
I got it from budgetgadgets.com
$21.66 New Keychain Green Beam Laser Pointer Pen Flashlight 30mW/50mW/100mW - BudgetGadgets.com
Here is the link to the laser from where I got it in the meantime

If you dropped it, there is a good chance you ALSO misaligned the crystals in the module.

What you gotta do is first pull the cap off, twist the back off and take the battery out. Remove the diode, lens, everything.
Then order a new one.
