can you tell the difference between those to alarm clock`s? the change is that the second one hides a key .....
i love this trick because it is simple and a lot of things have a 9v battery now .and REALLY is a burglar gone check every battery compartment in your house
Step 1: Remove the Cap
you take the cap of the battery holder . ignore the CAUTION HIGH VOLTAGE message because we are not opening the clock itself just the battery compartment .
Step 2: Remove the Batery and Place the Key
remove the 9v battery and lay your key inside the empty compartment
Step 3: Close It Up
put the battery on top of the key and close the compartment is should fit snug and without a noise when you shake the clock around.
so that's how you hide a key without braking something :)
