Hi Peaches,
The glove box lock was gummed up badly so the pins would not move when the key was inserted. I soaked the lock cylinder over night in lighter fluid then wiped it clean with cotton swabs. Then I rinsed with alcohol and finally lubricated it. It is working correctly and ready to be reinstalled.
After cleaning:
That is the same lock! The little things make a huge difference in the looks of a vintage car. One system at a time, it will come back to life.
