i am certain I have never tired my keys on a table that didn't work...my sample size is small, maybe a dozen tables but they range all over the place in age and location
i have heard it is universal, that is why the owner of the Brown Marble in our favorite bar drilled into the table to put a lock on it (although he never lost anything, he just became paranoid when he learned any key would work)
others can verify...try it out yourself, it is all kinds of fun
