Any tips for freeing up stuck door locks? The key won't turn in my driver side lock. Tried several applications of Dupont Teflon on the key, but no luck.

Get some WD-40 or similar "rust buster" . Put the red pipette on the nozzle ,
Spray directly into the keyhole , using a toothpick to hold the keyhole cover open .
Run the key in & out of the lock several times .
If that doesn't work try it again the next day etc .

Graphite works well sometime on old rarely used locks. Larry

Sorry, but never, never, never use WD-40 on any kind of lock. It will free it up temporarily, but turn into an unworkable sticky mess shortly. Graphite, or silicone or some kind of solvent spray, followed by graphite is the best.
