Easy enough for a 19 yr old girl
I just ditched the instructions all together because it was too o confusing. All I did was when I was removing the old door knob I watched how it was put together and just did that for the new one. I didn’t even need the other 3 pieces just the ones for the door knob because it fit perfectly into the “latch” hole (i guess you would call it) that was already there. It locks and opens great and it’s very secure. I thought it was gonna be difficult but it turned out to be so easy. All I used was a screwdriver. The only thing is I had to use my hands to put on the screws half way because the door knob handle was in my way when I was screwing in the screws.

Reviewed in the United States on January 14, 2021
Style: EntrySize Name: 1 PackVerified Purchase
Was super easy to replace my old lock, also comes with all the parts you need if you're installing on a brand new door. Hardware is great quality, and is certainly stronger than the one I replaced. There is anti-picking and anti-shimming (like with a credit card) security in place.

The keys are large and oddly shaped, but I kind of like it because it sticks out among my other keys. Using for a bedroom.

To the reviewers saying they are easily picked with a coin, pay attention to what handle style you're buying. A "passage" style is for a closet or other door that doesn't need a lock. A "privacy" lock locks only from the inside, doesn't have a key, and can be unlocked with a tool (or coin) from the outside.

And finally, an "Entry" lock comes with two keys and is much more secure. Can be used to lock a bedroom, garage entry, or front door.

Having to have dealt with the first doorknob I'd purchased prior to this one (a poorly designed Brinks) the installation was a snap and I must say I'm very. very impressed. I use this knob in the front door to my apartment. It really holds up even with the deadbolt unlocked it holds up very, very well. I performed a few of my own tests on it after installation and it wouldn't budge for anything. Highly recommended. ** I have noticed confusion with many reviews for these doorknobs crossing over to other knobs making it confusing to decipher which review is for what product. To avoid confusion this review is for the Master Lock BCO0115 Biscuit Keyed Entry Door rlock. I don't know why it did not include any tasty biscuits to enjoy while installing the lock (which takes a matter of minutes by the way) but still, I highly recommend it.

4.0 out of 5 stars Reasonable locking entry door knob
Reviewed in the United States on January 22, 2020
Style: EntrySize Name: 1 PackVerified Purchase
I purchased this for garage side entry door use. I have used this lock outside in winter weather (here that means 5-30 degrees F) with no issues. The knob/lock holds up to exterior weather perfectly well and and I have thus far experienced no issues. I have experienced no issues with key functionality, knob resistance or anything else negative to its usage.

This is a moderate entry door locking knob. It does a reasonable job at a task that is poor to begin with. Most of these products are put in use with all wood frame doors. Wood will break and give much faster than metal. While many talk on how easy these locks are to pick, a solid force to the door is going to get you past this anyway.

I find this product to be far better than the Kwikset it replaced in the climate here. If you are securing a wood door frame, the lock is not your weak spot to someone looking at forced entry. For one who is going to pick their way in, most all door locks pick the same. I suggest truly looking at your security needs and implementing accordingly.

I would buy this again, not just for my use but for home entry use over a Kwikset alternative. Yes you can pick them both, but the quality of this Master Lock set is far better.

The Master entry door lock was easy to install and has a great feel and finish. I don't reccomend reading the instructions because they might confuse you. I suggest looking up seejanedrill on youtube and watching her, "Installing a doorknob with a Keyed Lock video". It should only take about 5 mins to install.

If I could give one tip, when putting in the long screws to attach the knobs together you should screw it with your fingers first then finish with the screwdriver. Otherwise your screwdriver won't fit around the knob and you'll have a hard time.
