My dads house was built in 2016 and within 2018, the front door lock started to not work on key copies. They work fine with the ones given to us when they first got the house and before the keys we’d make a copy of would work too. We just don’t know what happened now. Maybe it’s the material of the key? Or maybe the weather rusting it up? I live in Minnesota (if that helps) the keys will go all the way in but they won’t turn to lock or open is my issue.
I know the solution to this is to change the lock but since he can’t afford that right now, what is another solution to this?
Our key copies are from Walmart. But I was told from a friend to try going to Home Depot instead for key copies and maybe that’ll work?
