Hello all, I just purchased my first home from an elderly gentleman who had recently passed away. He was the original owner of the house which was built in 1952, and while he kept the house in good shape, the materials inside the house are very dated, so I had to spend most of my budget on upgrading the electric, kitchen, and side entry door into the kitchen (which looked liked if was going to fall in if you sneezed on it). So as a result, I no longer am able to fund a replacement for the front entry door to the house at this time, which looks original but very sturdy, so I attempted to just change the locks. I went to take the lock off the door to replace it with a new one and discovered that the lock hole is smaller then a modern standard lock (only about an inch diameter) and the deadbolt mechanism is tall and skinny. It has an ornate design on the front where the keyhole is and a single but almost oval looking single action latch on the back. I'm looking for any ideas how to replace this. I cannot find anything that will fit at Home Depot or Lowes, and I don't want to try to drill a larger hole in fear I'll never get everything to line up. Any suggestions are greatly appreciated, thanks!
