Opening vintage cabinets with "stuck" keys

I have two antique cabinets- both with skelton keys stuck in the locks. They both worked recently but they are now stuck. I am moving the keys a bit but cannot unlock either cabinet. Any diy suggestions? Thank you in advance.

    If you have any oil handy put on a Q-tip and insert into the area where the keys are.

    Try a blow dryer to heat up the lock...after a little wd-40. The key should be thicker than the lock, and should heat up slower than the lock.!

    Is it dry where they are located or damp? Humidity could have something to do with it. Try spraying a little graphite in the lock and try it then.

    I would get a puffer bottle of powdered graphite. It's a wonderful dry lubricant for things like that. Oil or WD40 could damage the wood finish. You might call a locksmith for advice. Please let us know what works!

    Wonderful as WD40 is I was told not to use it on locks as dust can get trapped in it, etc. I was told to buy a liquid graphite product for locks. It has a tiny tube and you spray it in. Solved my problem with sticky locks I couldn't open.

    I have never heard of dry graphite but found it on a big box hardware store website. I'll get some and let you know how it works. thanks for the great suggestions!
