Who’s drilled out a trunk lock?

My cars sat a few years, the trunk key turns the lock but does not unlatch it. I have a firewall behind where the back seat used to be, and a fuel cell mounted center the trunk. Is drilling the lock the best option?

Re: Whos drilled out a trunk lock?

I don't think you have too much choice but to drill the lock. I know it's possible, I've seen it done at a GM dealer a long time ago

Good luck!

Re: Whos drilled out a trunk lock?

Been a LONG time ago for me BUT I'm wondering, IF the key is turning the lock and you drill the lock out, wouldn't turning it with a screwdriver or such be the same as what the lock is doing now?

Re: Who’s drilled out a trunk lock?

Frankie,
This might sound stupid but are you sure that maybe it is actually unlatching it but the trunk lid is stuck down by the weatherstripping from sitting for so long ? Maybe have somebody pull up on the lid while you turn the key.

Re: Who’s drilled out a trunk lock?

I agree with the lid being held by the weatherstrip.

And yes, if the key is turning the cylinder, drilling it out wont't help.

Owning a Chevelle project is like having a giant-size piggy bank that you keep pouring money into....but you can't get it back out.

Re: Whos drilled out a trunk lock?

Body guy set all my gaps W/O seals so my trunk has to be pushed down to get it open.

Re: Whos drilled out a trunk lock?

Have you sprayed something in the keyhole like pb blaster or Kroil in case the mechanism is stuck there. Living in a salt state, I have to do this every year to my truck.

Consider removing the back seat and entering the trunk to access from inside. Remove lock cylinder clip and lock cylinder and loosen fasteners at latch mechanism to free up any possible jam. Then you can use a screw driver at the latch mechanism instead of the key. Possible something is broken in the latch mechanism. You can get it open without further damage to work on or replace.

Re: Who’s drilled out a trunk lock?

maybe buy/borrow a scope camera thingy and reach it in through an opening in the firewall, just to see what the issue may be.
