Sorry, I don't know how to post more photos to one post, it says a max of 3, so this is the continuation.
Photo 4, Here is what you will find inside. Match mark the triangle contact piece so it can be put back in the correct place. There is a spring under the contact, but the lock will not pop apart, there is not that much pressure it. The triangle contact has a tab on the bottom so you will not be able to reassemble it incorrectly. Clean the corrosion of the contact. Pull the contact and you will see a circular plastic piece that the spring sits in. That piece has a pass thru contact, it may fall apart when you pull it out. There are 4 pieces to it. Two small brass contacts, one sticks out the top and one out the bottom and in between is a spring and retainer. Not difficult to figure out if it falls out. I cleaned the bottom side of the top cover, where the wires are soldered to. I used a flat file to make everything smooth and shinny.
Photo 5, all the parts from inside. You can now see the 2 screws that hold the lock core in place.
Photo 6, is the lock core removed. You can mow take this to any locksmith and they should be able to find the correct key blank and cut you a new key. If you have never taken a lock core apart, now is not the time to try it. There are 4 VERY VERY small springs in the core that you will loose of you try to disassemble this.
Clean everything, a light coat of dielectric grease when you reassemble the switch can be put on the contact triangle and the bottom of the cover. Just a FYI the # that is on my lock is 949, which according to Key Man means nothing usefull. I have my lock at the locksmith and will post the manufacturer and key code when I get them back.
