2007 Lexus GS 350 Trunk WILL NOT open. Tried “Everything”

[Randy43837]

Hey there…. I see this is a common problem but I have literally tried everything I have read and still the trunk will not open. Checked valet, unhooking battery, new battery, fuses, manual key and even rigging up a long handle t-wrench to turn the emergency handle inside from the opening in the rear seat.  I have tried combinations of turning the emergency while someone else was turning the manuals key.  Will not open.
 

Truly don’t know what else to try.  Thought I would throw it out here and see if there is something I am overlooking.  
 

Any thoughts would be appreciated!

Have you tried the button inside the glove box on the left side?

Spray some WD-40 in the key slot, Try this several times while using the key. Basically flush the lock mechanism and keep trying to move the works.
