To fix the trunk lock on a 1996 Mercedes S500, first, inspect the lock mechanism for any visible obstructions or damage. If the lock is stuck, try applying lubricant to free it up. If the key won't turn or the remote fails, check the battery in the key fob and replace it if necessary. For more complex issues, it may be necessary to remove the trunk lining to access and diagnose the internal lock components or consult a professional mechanic.
remove door panel to check it!!
To fix a trunk latch that is stuck open, the teeth on the lock may have to be adjusted so the trunk will close. It is also possible that the cable for the trunk latch is broken. To fix the gas cap door latch may require a little bending and adjusting with a pair of pliers.

Read your manual. There is a switch in the glove box to disable the trunk release button on the dash. you lock the glove box with the regular key. When you give someone the valet key they can not get in the trunk.

On my 1992 190E I can lock the trunk with any of the keyed locks. If you lock the doors, the trunk locks and if you lock the trunk, the doors lock. In other words all the keyed locks are electrically interconnected. In reality the locks are not electrically interconnected. There is a pump in the right side wheel well of the trunk, it uses vacuum to lock all the locks and pressure to unlock them. Although the pump is powered electrically, the locks are not.
