The Lane deadbolt lock is 30 years old and has started to become loose in the door.
A key can be used on both sides, but only the side inside the house has 2 pins.
I don't know whether the pins are screwed in or should be prized out.
Even then I don't know whether the screws holding the 2 sides together are Phillips or screws which have to be drilled out.
So, before I have to call out a locksmith, I wondered if there was something I could do.
