Sorry if this is against the rules, I don’t think it is?
I have a 1980s safe with a secondary inner compartment inside. It used to have a time delay lock, but it was cut and has not been working for a while. The secondary door has this Medeco lock. I do not have the key, but luckily the door was left open. Am I able to just replace the cylinder on this with one of the many Medeco cylinder and key sets on ebay? Or do I need to get the entire thing?
