With the original keys, they were both solid metal (no plastic) but had the toyota logo on them. If it was an master key it would look similar in shape to http://s7.cdn.hardwareandtools.net/is/image/HardwareandTools/036448173938?wid=200&hei=200 whereas the valet key would look more like http://s7.cdn.hardwareandtools.net/is/image/HardwareandTools/036448181704?wid=120&hei=120 (not 100% identical but close enough). By the sounds of things the previous owner must of had a key cut thats not perfect because if it were the proper toyota key no matter what type it would unlock the doors (unless it was really worn). All I know is the actual remote is what disables the immobiliser and I believe that that's the only way to disable it. In the end it wouldn't hurt trying another cut key, it's not too hard to get access to the ignition barrel (you have to start by prying the U shaped plastic trim underneath the radio from the bottom corners of the trim, there are then two screws in the top corners to remove, then remove the two screws above the speedo, then you should be able to slowly remove the trim around the dash (the rest of the trim is held in by clips, that should then allow you to see the ignition barrel)) 1995 was the year they went from the gen 3 to the gen 3.5 camry therefore the process of disabling the immobiliser may be different to what I said before(i have the gen 3.5) Hopefully you have some luck (btw what actually happened to the keyless remote that locked/unlocked the doors - that is if you had remote central locking)
