I browsed through the forums here and didn't find the answer I was looking for, so I was hoping someone might have a solution to my problem.
I have a 91 LS400. I have 1 regular key and 1 valet key. While at the shop, the trunk lock button was pushed. However, neither key will unlock the button so I can get into the trunk. The main key is a copy of a copy, so it never reliably opened the trunk, I always used the latch inside to pop the trunk. Now, however, it won't do anything.
I insert the regular key into the trunk lock and it won't turn at all ... left or right. It acts like it's the wrong key altogether. This car is a hand-me-down from my grandmother (the original owner) and I'd never locked the trunk with the lock before, so I am not sure if this is a new problem or has always been the case.
A side note, the glove box is not locked -- I managed to get that one to open with the key.
If anyone has a solution for how to get the lock "unlocked," I'd greatly appreciate it. The car shop I had it at when it happened can't do anything. The Lexus dealer said they can't tell immediately but I can pay the $99 diagnostic fee to see if they can figure out the problem and a solution. I don't want to pay $99 though to have them come back and say it will be $600 to fix it.
Any ideas are greatly appreciated! Thanks in advance!

Sounds like the copy was made of the valet key instead of the master.
On the 95-97 the master has a ridge toward the tip. The valet does not. Toyota has used a similar approach on their master-valet keys since I began driving their cars in the 80's.
The $$ approach is to order a master key from the dealer for about $250 bills you'll need the VIN and car registration when going to the dealer to show proof. There may be a way to braze-solder the ridge but it is risky and may damage the key and it will take some trial error to match it.
Master key is on left, valet on right for reference, the ridge is on both sides of the key.
if all you really care about is getting the trunk open then PM me and i'll give you a rundown of how to get past the locked latch. being as it is reasonably sensitive information and i dont want anyone getting their trunk jacked i'd prefer not to post it publicly.

I am not sure if this will help, but I have a 91 LS400, and I also ran into problems when I accidentally pushed in the trunk lock button. The key did not turn, at least not right away. I had to jiggle it back and forth and side to side a few times, and then magically it opened. All the other locks work fine. Long shot, but maybe worth trying.
I had the same problem...removing the plastic cover under the locked key section and fiddling around will pop the trunk and bring it back to 100% condition...PD would seem to have the recipe which he offered to you..
