Safe and secure- need doorknob/lock advice
I hope you can provide some advice and suggestions for my situation. My 63 Overlander came to me with only one key for the exterior door, which I believe is the original round doorknob. As mentioned many times in the forums, finding a key blank to have a spare key made is challenging, and I've been unsuccessful. I've considered changing out the cylinder, as the key is difficult to turn most days anyway, and will continue to keep this option open. But here's where I am hoping your wisdom and infinite knowledge will help me. -- I need a way to lock the door for safety when I'm inside. There is currently no way to engage the keyed lock except from the outside. I've considered adding something to the inside (deadbolt, slide lock, chain etc) but wondering since I'm having so much trouble getting a spare key made if I shouldn't just replace the entire handle to a model that locks from the inside as well (and has more than one key!) Are there original parts floating around out there that I should be looking for or was an interior locking knob not even a consideration back in the day? Do you know of anything that I can update with - I've checked the Inland and Vintage trailer supply websites and it doesn't look like they have what I need. Is it possible to rig something up with a combo of original pieces and new materials (ie- add a different knob to the inside that locks and change out the cylinder?) Any advice or suggestions would be greatly appreciated.
Happy travels to you all,
