Changing a doorknob?

[shirokado]

My room door doesn't have a lock on it, so i want to add a lock do it, but I have a couple questions

 

 

1. Is it hard? (compared to building a computer)

 

2. Is it expensive(compare to like.... ram?)

 

3. Are all door knobs the same size? or do i need to measure

[Jeroen1322]

1 it is not hard

 

2 Mmm don't know where you live and what stores sale doorknob's

 

3 almost all the doorknobs are the same size i believe don't know for sure

1. This depends, does your door already have a knob with no lock mechanism or is there just nothing on it? If it has a knob already it's a matter of removing a few screws, putting in the new knob and putting in a few screws. If it's the latter you'll have to cut a hole or buy a door that already has a hole for a knob.

 

2. Door knobs come in a huge price range. Simple cheap ones go for $20 to $30, other can run you $200. 

 

3. Most are, I've never seen a different size.

Not at all hard, a beginner can do it.

most interior doorknobs I can change out in 5-10 minutes

if you can reuse the previous latching piston mechanism then all the easier

I have come across different middle latching piston mechanisms that are incompatible with some newer ones

 

when having to change out the middle piston mechanism I've sometimes had issues with holes being mismatched and needing a file to increase the size of the hole to accomadate the mechanism.
