I have a 95 sc300, and I can tell you I have the original key which is an older style of key with only a single button on the side, and the valet key has no button on it at all. basically no trunk release on the key at all.
I don't think the 3 button lexus key with the trunk release came out till a later year at least on the 300 unless the 400 is special and got it early.
are you sure you have the original key?
there was some conversion kit for the 1 button to 3 button floating around which required wiring a module in the trunk but its not very common and you would prob know if you bought it or not. It is possible for a previous owner to have installed one, then you will have to find the module and check the wiring.
If you are talking about a button on an aftermarket alarm system, it could just be not wired up to the trunk even though the beep is responding to the remote when you press it.

I too have '95 SCs (3&4), and I have to concur w/ Ali, as far as I am aware the original remote Key has no function to open the trunk (remotely). Not holding the button or double push, simply doesn't do that. Same way it only unlocks both doors (no single for driver, double for both). It is just lock / unlock both doors all or nothing. I did recently come to find that if the front hood is not latched, the key will remotely unlock the doors but not lock them (although you can always manually lock w/ the lood unlatched... Just another 2 cents

Thats interesting does anyone know if there is a trunk release on those keys? As far as supports go ebay 26bucks will get you supports that work really well. Its the 11.4 inch in expanded length not the 14in. 1 screw and it pops off and you are good to go.

I have a 96 SC300 which has a seperate key fob from the key and it has the trunk pop button.However it never worked well have to be very close to the car for it to work. I just installed a Viper keyless remote system right where the oem keyless modue is and everything now works great. Can now lock/unlock door and trunk from 100 feet away. Factory alarm still works like it should to. Paid $55. for it off eBay.Model 5103 I think.

Where in GA are you? I hooked up the lock/unlock and trunk pop wires at the stock alarm module plus the 12 volt + and the ground. Works great, the factory alarm still works as it should. All you are doing is replacing the oem keyless system. Check out 12volt.com they have the wires color codes and location for the SC.
