Take the lock apart again. Behind where the key goes in, there may be a
screw on cap, that holds the plug in. Might have to depress a pin, and
tighten the screw on cap a bit.
Liquid wrench (and graphited lock fluid) tend to dry up after a while. I use
WD-40, or spray silicone.

I had to paint my French patio door. I removed the latch lock and the
deadbolt lock, a 30-year old Schlage product. Both locks are brass but,
being outside locks, they are somewhat corroded.
The deadbolt lock has keys for the inside and outside. When I reassembled
the deadbolt lock, the key would move the bolt, but the key cannot be
removed from the inside cylinder. The key turns the cylinder but the key is
stuck in the cylinder.
I was thinking of inserting some liquid wrench through the key-lock next to
the stuck key. Would that be OK or gum things up completely
