My guess is a previous owner had some accessory item lose power (possibly due to a blown fuse or intermittent open/short) and then simply hardwired it to a constant +12V source. Or maybe they wanted something to run full time when it used to be switched by the key. When you replaced the fuse you've now sent that full time 12V back to the 'ignition' wire via the fusebox, essentially bypassing the key.
Pull the fuses you replaced one by one until the problem goes away.
Does the dash look like the key is 'on' before you turn it on? When you turn the key to 'on' does it make a noticeable difference? If so then the disregard the above.
Pulling fuses like someone suggested earlier is still a good idea, though.
