I'm trying to remove the door lock cylinders on my '48 coupe. As you know, the cyls. go into an aluminum or pot metal casting and held with an allen set screw, which won't budge after soaking with penetrating oil and twisting as hard as I dare on the allen wrench. I don't want to do anything to damage the door or paint. Anybody have any ideas? Thank you.

Sometimes just applying penetrating oil several times over a long span of time will allow the screw to turn, but most times you will have to drill out the screw. Tom

wear eye protection. NO exceptions. Exceptions are called 'accidents'...

Did you try some stuff called "Kroil"? Also I see many recommend acetone mixed with transmission fluid to break up rust.

Use a 50/50 mix of acetone and transmission fluid. It's twice as good as Kroil and four times as good as WD-40. Here's proof: http://www.antiquemodeler.org/sam_new/news_letters/assets/wham_2011_07.pdf

A great tool for drilling out reluctant parts is a "reverse twist" bit set. It rotates in the opposite direction of regular drill bit. When you reach a certain point, the bit simply backs out the threaded part.

Be cautious about using the acetone - trans fluid option. Acetone can damage or remove paint. Use a penetrating oil such as Kroil, PBlaster or MMO. WD40 does not do much for rust penetration. Tom

Thanks, gentlemen for your suggestions. I have tried Kroil without sucess. There is no way I am using acetone anywhere near a new paint job. A reverse drill may work if it is available in carbide type. Those allen set screws are hard!!!. I have about decieded to take the car to my local locksmith and see if they can make a key by measuring the lock. I'm told it can be done. Thanks again.

If it is the original door lock, the ignition key will fit it. If not, any good locksmith can make a key from the lock itself.
