How do you unlock child safety lock on a 98 Cavalier

SOURCE: door locks

Regarding the rear door child locks: There is a small lever on the latch side of the door, you can only see it with the door open. Move it to the other position.

Regarding the front door locks: You either have a bad door lock switch, or the power lock solenoids are beginning to fail. To check this, you will need to pull the door panels off, & measure the actual voltage at the solenoids whilst manipulating the lock switch. If you have 12 + VDC, I would suggest replacing the door lock solenoids. Not hard to change, but it IS time consuming. Best left to a dealer. Expect to pay 1 hour per side to change each solenoid.

1. This is what probably occured
2. While the door was open the latch on the door was closed
3. If the spring inside the latch is broken, Working the inner or outer door release handles will not open the latch.
4. place a screwdriver in the opening of the latch where the door striker would be if the door was closed.
5. apply pressure to the latch paw while operating door release.
6. latch should open.
7. replacement of the latch will keep this from happening again

Your post is somewhat confusing, BUT with child locks engaged, you can only open the door from the outside, when unlocked.
