Factors affecting the cost of doorknob installation

Different things affect doorknob installation. Prices will also vary according to the type of doorknob, your location, and additional hardware like double locks.

Doorknob type

  • Keyed entrance

This doorknob is typically part of home exteriors and bedrooms. You can lock it without a key, but you need one when opening the doorknob from the outside. Be careful when installing it, especially if you're a little forgetful. Be sure to have a spare key.

  • Privacy

Most of the time, privacy doorknobs are for bedrooms and bathrooms. They have a lock control mechanism and offer complete privacy. You can easily open them from inside a room, usually with just a turn of the knob. Privacy doorknobs have a generic key for opening the door from the outside, just in case children accidentally lock themselves in.

  • Passage

Passage doorknobs don't have any locking mechanism and are usually for doors leading to kitchens or laundry rooms. You can open them inside and outside a room, so they don't offer much security.

  • Dummy

Dummy knobs are completely stationary, so you can't rotate them. You only use them to open doors. You can find them on kitchen and bathroom cabinets where you quickly access your stuff.


Your location plays an important role when installing doorknobs. The farther you are, the more you will pay for the labor, as this will include your installer's transportation fee. Urban homes are easier to access than those in the countryside.

Additional locks

Installing double locks will cost you more. However, they're a good investment, especially if you attach them to your main door for added security.

Smart lock systems

These are becoming popular among households these days. Perhaps it's because you don't need to worry about forgetting your keys inside your home anymore. However, smart lock systems come with a hefty price. Expect to pay $250 to $400 if you want to buy one.

Can I install door hardware by myself?

Yes, you can, as some stores offer DIY kits for doorknob installation. However, doorknob installation requires proper measurements of different parts, so it's better to leave it in the hands of an expert. Inexperience can lead to security issues. 

How do I find someone to install my doorknob?

Doorknob installation in households doesn't require any license or permit. However, inform your tradesman about the minimum building security standards for mechanical locksets if you're a business owner. You can ask your friends and family for recommendations. However, if you dislike the hassle, Airtasker offers services for installing doorknobs.
