Master LockTUO0105 Tulip Door Knob with Lock, Antique Brass

I needed to replace my old lock because the deadbolt was sluggish and I didn't want to have two separate keys (so I ordered this whole set).The Master Lock TUCO0605 came in many pieces in a hard shell plastic packaging. To my surprise the manufacturer included 4 keys (all the same).Installation was quite simple and took me about 20-30 minutes. Tools needed: Screwdriver, Phillips screwdriver and a tongue. Maybe you don't need the tongue but my lock had a steel frame/plate on the outside with a hole for the old doorknob (which had two 'noses' that didn't fit the two screw-stems of the new one so I had to bend them inwards). If you don't have this metal plate on your door - forget about the tongue.The deadbolt has a key side and a lever to turn around (lock/unlock) on the other side (the side you can not see in the official product photos). You can actually reverse the two sides so it doesn't matter in which direction your door opens.The doorknob unit also has a key side and a lever (lock/unlock) on the other side. Same as with the deadbolt, you can reverse it.The key works the following way on the doorknob unit (same with the lever on the inside - just reverse):* Turn the key 90° clockwise and the doorknob is locked. You cannot turn it anymore. If you close the door now you could lock yourself out.* Turn the key 90° counterclockwise and the doorknob is unlocked. Now you can turn it. In this mode you can open and close the door without a key.* Turn the key ~180° counterclockwise and the doorknob is unlocked and the door opens as if you would turn the doorknob.[* directions assuming the hinges are on your right when standing outside looking at the door]QUALITY: Pretty good for ~$25. It's solid and about the same quality feel of every other doorknob I have ever used. I guess you could buy better quality with more money for an even smoother key fit/movement, but I'm totally satisfied. The doorknob is a tiny bit loose (you can rattle it a bit if you like), but for that price I don't expect it to be precisely crafted as a Swiss watch.

Worked as expected. My handy-man brother installed without problems. I like that the oval shaped keys are a little larger than most keys. Came with 3 keys, made 2 extra copies. The local Ace Hardware had blank keys similar to the MASTER LOCK keys, but there was a $1 extra cost due to the large key size. I think the larger key size makes it easier to handle and would recommend to a person with arthritis in hands or wearing heavy gloves. I think I would have preferred the inside door knob to unlock by turning the door knob instead of turning the lock before opening the door, but the design has its merits.I would recommend and buy again if needed.UPDATE: I bought another set as my brother misplaced his keys and were found by a friend of his. I was told this person could not be trusted and could have made copies. We put an old lock on the door and I ordered this lock the next day. I can confirm that the new lock has a different key code as the previous lock. I went to Ace Hardware to make copies as before, but Ace no longer had the specialty keys as they had a new automated key cutter. I guess I could go to a locksmith that I'm sure has specialty keys but more expensive.

Okay - I needed to replace the deadbolt and doorknob on my front door and this looked like the perfect replacement.First of all, the lock and deadbolt are solid and I don't have any complaints about the locks and mechanisms. My big complaint is that these do not fit all sized doors as stated. In my case, when I took off the old door knob to put the new one on, the hole in the door to accept the new knob mechanism was too small for this knob. The knob cover on the key side of the mechanism has a lip on the inside that faces the door hole. You can't see it in the product photo because it faces away from you in the photo. It sticks out about 1/8-inches. The door hole has to be at least 2-inches in diameter to accept this lip or the keyhole cover won't fit flush to the door. My door had a 1.5-inch keyhole so the knob cover lip would not go into the hole. The lock mechanism fit in fine, but the cover would not come up flush but stood out from the door a good 1/8 inch. I did not have a keyhole bit for my drill that was 2-inches in diameter, so I had to hire someone with the right tools to come and drill the hole out and install the product.The deadbolt cover did not have that lip on the inside, so it fit the old 1.5-inch deadbolt key hole in the door just fine.Once the hole in the hole was widened, the doorknob fit fine and works fine and I have no complaints about it's operation. It just cost me an extra $20 to have someone with the right tool come over to my house and make the hole bigger. This is just a warning to all to make sure your door has at least a 2-inch key hole in order to accommodate this knob and mechanism.

Buena calidad y facil de instalar

It was easy to install, fit perfectly and works as promised. Great deal, fast delivery - would buy again!

great quality, easy to install, (I borrowed a jig), looks good and all for a really low price.

Easy To Install , Sturdy at Low Price

I bought two packs of the twin pack to use indoor. The two sets of keys (eight keys in all) are identical and compatible with all four locks which is great since I do not have to carry keys around and no need to copy any for additional confusion!!! However, the locks do not appear to stand outdoor tough jobs or high security jobs.
