I have an buick regal custom 1992 and in my glove box there is a trunk release button. yellow. Not sure if this is a standard
Look under the trunk's lid.
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.
I came across this problem. There is a lock below the steering wheel that will cause the trunk lever to disengage when it is pushed in. Use the master key to turn the lock (located below the steering wheel). It must be the master key. Without the master key you will need to remove the lock (located below the steering wheel). Good luck.
turn the key
