Normally you remove the back seat back, and pull the emergency release. Or a mobile locksmith can get in. If the lock is worn, any similar shape key may work with some jiggling. Also look in the glove box for a release button.

I just found this in your Owner Manual for Cutlass Supreme

Remote Trunk Release (OPTION) Press the yellow trunk release button located under the instrument panel on the driver's side. Your automatic transaxle must be in P (Park). Remember that your trunk can be opened at any time using the lock release. Be sure to lock your doors

and also access into the back.

Trunk Access Panel If you have split rear seats, you may have a trunk access panel for storing long objects like skis. Pull your rear armrest down using the strap. Then pull the latch on the trunk access panel towards you to open the panel. To close the access panel lift the latch.

Sounds like the remote receiver module in the car is malfunctioning and will probably need to be replaced.

When you press the trunk open button, do you hear any "release" noise come from the trunk area? The issue may be a bad battery in the key fob OR there could be an issue with the transmitter located inside the vehicle. Do the doors lock and unlock properly? is the vehicle equipped with security or immobilizer? please advise

Lower the back seat and crawl into the trunk and see what the latch is doing when you activate the key fob. the trunk lid will have to be open to enable any repairs. Also an emergency release cable is probably visible (yellow handle) inside the trunk and will Open the trunk lid.
