Gunlok special trick

[Fishbones]

I just picked up 2 guns that belong to my father who passed away on June 1st.The first is a H&K 45 pistol that had a cable lock on the box,the 2nd is a Remington 870 shotgun that has a Gunlok over the trigger.Went to the web site gunlockinfo.com and they say even if you have the key (which I do) you need to know the trick on how to push the buttons.Any body know the trick?

Thanks Rich

There should be 2 buttons. The trick is to only push one.

Sent you a PM on how to open it. No need to broadcast the secret to those that should not know.
