I am the original owner of a 98 OBW w/147,000 mi.

 

This morning, for the first time ever, I could not open the rear hatch.

 

I tried using both the power lock switch and the key. The key would turn but the hatch wouldn't open.

 

Has anyone else had this problem?

 

Is the only fix to have the lock replaced or is something else likely wrong?

its probably the handle and bracket rusted out. If you do a search here you'll find part #s and directions on how to replace it. Is the bracket rusty?

here you go

I have the same problem, it is because of a rusty latch mechanism prevents the return spring from fully returning (retracting) the latch handle. Use your fingers to pull the handle all the way back. If the handle is not in the "fully returned" position, the key or auto door lock button will not open the hatch. That seems to be what you are experiencing.

 

I get some relief from this problem by lubing the latch mechanism, but later new rust forms to cause the problem to return.

How cold was it today?

It's any easy fix BTW, I had the same problem. It may be that the hatch handle has not returned to the normal position. Also spray the hell out of it with penetrating oil, that should unfreeze it, but you need the new hardware.
