Review on Lucky Line Combo Skeleton Key 1 Flat 1 🔑 Notch Tip, 2 Pack (87202) - Improved SEO-friendly Product Name by Dylan Deng

My friend's mortise locks from the 1920's are stamped with a '3' on the outer lid. However, both keys (2-bit and 3-bit) work. In fact, a 2-bit key (the one with no label) works better. From what I understand the number 3 could be a production line or something. It took as long as said to get here but you can't beat the price! Someone wrote something about a broken head. The original keys to your mortise lock were probably iron. These are brass plated zinc and they are not that strong. I'm sure it would be very easy to break off the heads of a rusty or otherwise stuck lock or bolt. Therefore it is IMPORTANT to prepare the latches and/or locks by cleaning and oiling: Part I: Disassembly (3 steps only!) 1. Remove the door handles.2. Remove the bezel (the metal plate where the door meets the wall and where the latch and latch are).3. Remove the entire block from the door. That's all! Don't disassemble the box itself by unscrewing any more screws until you've tried everything else. Installing in the box is very easy, but there are at least 2 springs that can easily pop out and get lost. Part II: Clean Bolts1. Lubricate the bolt (just the bolt so far) with some multipurpose oil like WD-40.2. Wipe clean with a clean cloth. Repeat or wipe as needed. Part III: Lubricate the Bolt and Lock1. Spray the screw again with the same oil.2. Wipe it off with another clean rag, leaving a light film of oil on the screw (if the oil is allowed to drain over time, you left too much oil) 3. Make a very quick shot or squirt of the same oil inward and up at the spot where the key will enter. Ready! Part IV: Assembly and Testing1. Undo the very first three steps (in other words, return everything as it was).2. With the door open, try to use the keys carefully. I say "with the door open" if the latch doesn't match its place in the wall. Let's hope the problem with the key is solved! Problems: If the keys don't work when the door is open, there can be at least three reasons: a) Something is stuck or stuck on the latch. Repeat parts I through IV. b.) Something is wrong with the box I told you not to disassemble. Have someone who knows mechanics take it apart and take a look. c.) These are the wrong keys, but now you are ready in case you found the right key(s)! Much luck!
