Car stereo problem!

[Aardvark]

I just purchased a 1995 Olds Cutlass Supreme convertible & the factory radio(Delco?) has "LOC" displayed & doesn't work. I believe it's in the "locked" state.

I need advice on how to "unlock" it otherwise I guess I'll have to take it to the local GM dealership & have them do it.

Thanx... :ninja:

Disconnect your battery and see if that works.

Delco Lock II (also called Theftlock), the next generation of anti-theft controls, features an owner-programmed lock code which is entered through the radio controls. If the customer programs a lock code into the radio and memory power is lost, "LOC" will appear after power is restored. The locking code must be entered to allow its use. If the customer does not have the code number, the radio may be unlocked by an authorized General Motors facility using special access codes.

I'm guessing that's why it's locked in the first place. I had the same problem with mine when the battery went out, luckily I was replacing the whole sound system.

It took a couple of hours but Ron Anderson GMC did it! Hoorah!
