Is this product adaptable for all weather conditions? Have you noticed the locking mechanism failing due to rain?

Hi, No chance of it failing due to rain. Unless it gets struck by lightning that is.... To tell the truth, this is as tough as old boots and if you keep giving it a little oil every year or so it will, more than likely, out last you. lol

Does this box prevent data being copied from keyless car fobs that are locked in this box?

My guess is that it should do as it is effectively a Faraday cage

how do I unlock if the combination has been changed, and don't remember the new combo.

There's no "secret" code to unlock it, unfortunately. There are videos online that purport how you can find the code but I cannot speak for their accuracy having never tried it. If all else fails, pry it off the wall and hammer the bejesus out of it to open the back! Good luck!

Would this fit a Chubb Key size 11cm?

The large unit will fit 11cm key Vicky. Make sure you don't order the smaller unit as there are two size safes. Cheers  Trevor
