I had just got done installing a new trunk weatherstrip seal on the 63 impala. I let it sit for an hour then closed the trunk lid only to realize the key turns the lock but it won’t pop open.

I think it has something to do with the vacuum trunk coupler possibly not being on correct. To top it off the vacuum hose is disconnected so I can’t open it that way.

Is there any other possible way to open it beside drilling out the lock?

One may enter the truck from the back seat. Remove bottom and back 'cushions' to gain access. Crawl in and 'unlatch' the truck from the inside.

But, before crawling in, try lifting the lid simultaneously with unlocking.

I have no experience with the vacuum trunk release option, but on the cars w/o it, the tension in the 'bar' springs 'raises' the lid upon unlocking'. It would surprise me (and very well may) if there is enough 'force' from the vacuum to raise the lid.

Hope this helps.

Pete

Over time, the rod that connects the tumbler to the lock assembly bends from use. Pull it apart and look at the flat piece of steel.

My guess is that by twisting it back in shape, you'll have better travel when turning the key.

that's exactly how I fixed mine

I got the rear seat out of the way and the board that I have my amplifiers mounted to but no way all 295 pounds of me is fitting in there. Right now I’m just trying to find something long enough with enough of an angle to try to pull the clip out that holds the lock cylinder in place against the trunk lid.

Got it. I had no choice left but to drill out the lock. I had a one key kit for the whole car now I’ll have a separate trunk key.

Oh well it’s open. Now the joy of trying to set my amplifiers back in place. Extra joy being 6’4” tall crammed into the trunk

A good locksmith can rekey a different trunk lock to match your other keys by giving him two locks ( a trunk lock & one from the doors or ignition. )

Pull the ignition cylinder, and give the locksmith the key number that is stamped on the side of the barrel. If there is no number, then give him an original key, and he can "read" the peaks and valleys to determine the correct wafers to install in the new trunk lock. Best to find an old time locksmith company, because they will have the most experience dealing with automobile locks of 50 years ago.
What was the cause of the lock mechanism not releasing?

Never argue with an idiot. He'll drag you down to his level, then beat you with experience.

Too late now, but you may have had to push down on the trunk lid and turn the key. Since you have a new weatherstrip it may have had too much pressure pushing up to make the latch release easily. Keep that in mind when you put in the new lock cylinder. The trunk lid may not want to open again once you put in the new lock cylinder.

Before you pull another lock (door or ignition) call a few reputable locksmiths and se whether they can rekey it from your key. Most good locksmiths can gage the notches on the key and match to tumble 'size' as long as they can get the correct tumblers for your lock

this may sound dumb but most of the time the linkage fell off in side the lock.

Get a trunk monkey. Then all you will need to do is say Open Sesame.

It sounds like you are getting some good advice. Don't get in a hurry. I would try pushing down on the trunk first. Next, try to find a young small friend to crawl in the trunk. A locksmith is also a good idea, you would be surprised how fast they work. The drill is the last resort.
