Review on 🔒 Satin Nickel Signstek Electronic Keypad Door Knob Lock: Enhanced Security with Encryption Function by Andrew Krishna

I have a lot of experience with keypad locks. I have worked with models from IEI, Marks, Alarm Lock, Isonas, as well as consumer offerings from American Lock, Schlage and Kwikset. my thoughts on this, in no particular order: * Ease of installation. If you know the difference between a Phillips and flathead screwdriver, you should be able to install it. BUT: If your house was built in the 70's, look at the latch on your door. The little thing that actually keeps the door closed. If it's straight out of the round hole in the door, you'll need a chisel to finish the installation. If your door lock consists of a rectangular plate held in place by two screws, you don't need a chisel.* Easy to program. Some of the locks I've worked with are so complex that programming them is a real headache. The only argument I have for programming this lock is that you have a fairly short amount of time to enter the codes, but as long as you read the instructions and write down what you're going to do, it's pretty easy. * Sturdy construction! This lock seems to be more secure than locks that cost four times as much. I don't know if this will lead to long life, but we can hope. * Beep is loud. I ordered two of these, one of which is mounted on my bedroom door. The alarm is loud enough to wake everyone in the bedroom. I fixed it by half opening the key lock and turning off the beep. Now the lock in the bedroom is silent. It took me 10 minutes to remove the lock, disassemble it, take the cover off the buzzer and put it all back together.* You can't "unlock" the door. I mean there is no way to make the lock work like a regular interior door handle. You always have to interact with the lock to open it. However, there is a "skip" feature that is a reasonable compromise. It also means this lock can't be 'locked', shall we say, so you can't use it on a bathroom unless there's some other locking method like a deadbolt. When programming, you need several different codes. The lock can support up to 10 codes, but they have a special format. The first digit of the code determines what the code can do. Code: Function: 0 main program code 1-8 user codes 9 access code All 10 codes open the door. Only after entering the master code (0) can you add or remove other people's codes. To activate pass-through mode, you must have programmed the 9th code. Anyone who knows the master code can add or remove codes. This is useful if you want to give someone revoked access. "Cleaning ladies, housekeepers etc.) To activate the access mode, enter the access code (access code starting with "9". Once the lock stops beeping but before the backlight goes out, press *# quickly and a short beep will sound. At this point, the lock will unlock as soon as any button is pressed. This effectively makes the handle available to anyone who understands the operation, and it's pretty easy to do. To disable pass mode , you must do the same. Another interesting feature is the "Encryption" feature. All of this is actually a lock, regardless of the amount of useless numbers you type. For example, to open a lock, let's say, Your code is 854321. You need to enter 854321# and the door will open.With "Encryption" function, the lock allows you to enter 8-482998563834085475834573943830480395048940-54321# and it will always still unlocked. Numbers entered between the first digit and the rest of your actual code are ignored and the lock will be unlocked if thereafter The last digits entered match your code. This comes in handy when you have someone watching you enter your code and you want to confuse them. Emergency unlocking is also easy to carry out. There is a rubber plug on the underside of the lock that can be pulled out and into which a backup battery can be inserted. This will power up the lock when the internal batteries are low and allow you to gain entry. Batteries are only available INSIDE the lock. There is no key. Overall I like this castle. Two things I would like to see not enabled: 1. Code that disables the beep.2. A mechanical override within the lock that can set the lock to permanent unlock, combined unlock or key lock (for bathroom use).
