With the lock mechanism missing, look into the hole where the lock should be. Take a flat screw driver and insert it into the slot near the back of the lock hole and twist.
May have to remove rear seats and get in from there
You can probably open it with a flat blade screwdriver. The lock itself has a flat blade shaped rod that releases the latch. If the lock is gone, look for a rectangular shaped hole in the latch. Insert the screwdriver and turn clockwise.

how do i replace a trunk lock with another lock that has a key
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.
* Remove the trunk lid latch * Detach the lock release box from the latch assembly * To detach the lock cylinder from the trunk lid pry off the retainer
You have to open the trunk lid, under the lock on the inside you will find a screw, remove the screw and the lock retaining clip, pull the lock out. If you can not open the trunk lid, drill the lock center out, and you should be able to open with a screw driver.
It is not possible to replace the trunk lock on a 1993 Caprice Classic while the trunk is closed. A person will have to remove the back seat, crawl into the trunk and open the lock manually before it can be replaced.
