1993 SL 500 trunk locked. will not open with key or remote.

Question edited for clarity.
Question moved from Television and Video category.

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.

Buy you a service manual at auto parts store for that yr., make & model

your car does not have the function on the remote for opening the trunk only i think,
if the trunk stays locked with the central locks,than you should turn the key in the trunk lock for different position,
if now straight,turn to flat,if now horizontal,turn to 6 oclokck position,

did you try the trunk lock, that lock operates the look too, or change the battery to the remote.

remove the back seat. and try it from inside

If your olds is anything like my 1993 Ford Thunderbird the glove box switch only works with the key on. To get the keys out of my trunk, also locked in with the remote, I had to remove the back seat.

1. Open trunk
2. Place latch in lock position
3. Pull inside trunk release to see what isn't moving
4. If trunk key won't turn, the key may be worn out and need to be replaced

A dealer or qualified locksmith can make a key from the VIN, provided the lock cylinders are original. Usually they will require proof of ownership before doing so.

Go through the back seats...they pull down 60/40.

if you can drop back seats you can get in and manually flick the lever when it is open you will have to go to dealer to see if you can get a key to match or you might get 1 in a junkyard. if this helps please rate me
