Servicing a Mortice lock

[whitelever]

I know this is not a lock picking question, but I was just wondering about servicing mortice locks.

I will normally strip a lock and clean it with meths then reassemble (replacing worn parts) and then lubricate wilh teflon grease. unless anyone else has any alternative methods?. I know WD-40 is not favoured?

Well what you have described is cleanxing a lock not servicing it.

A lock service is replaceing the moving parts if worn even slightly.

I would tend to use white grease if grease is needed otherwise a good ptfe spray (the type that actually leaves a coating of ptfe) is adequate, remember you dont want grease on the key then put into the customers or your pocket.

Thank you so much, this is something I would never have thought of - I'm used to working on larger objects - such as ride-on floor scrubbers, not things that pop into your pocket.
