Question: is this a key in key out lock?
Document: I buy this because I need extra lock on my door and since from Master Lock I but it.But will not recomended for home security, it is very easy to open it with bumpping key.
I got these to replace another brand that failed to work when I tried to key the keys alike... so I switched brands to good old master lock and sure enough, they are easy to install, and look great. work great too!
The Master Lock Deadbolt and the Keyed Entry Door Knob have the same key, and hardware stores don't carry that key. So while you can't make duplicates, everyone who purchases this lock will have a key to your door. Ordered three, one was broken. Wish I hadn't purchased this lock.
wasn't bad, easy to install and worked better then the more expensive lock I had before hand.. got it in under 2 days.
The adjustment of the lock setback was difficult and the instructions were not clear. Although the parts were all metal and the fit and finish was fine.
Received the item - Good quality and finishing of this lock. It is Easy to assemble and fix. Comes with simple instruction booklet
For the cheapest master door lock to choose from, I am quite happy, no need to spend another $20 on this item
This is a solid powerfully built strong lock. Once I had this installed, I could sleep peacefully at night and not have to worry about somebody trying to "jimmy" my lock open like before. Fool proof and secure and best of all, easy on the wallet.
I purchased this deadbolt as a replacement for one of our back doors that isn't used much. Therefore the only reason I gave this item a four out of five is because we've probably only used this door once since we bought the new lock so I'm unsure about how well it wares with consistent use, but it seems sturdy and does the trick for us.
This is replacing an old deadbolt in my basement door. Installation was a snap - frankly, all that needed to be done was to take out the old deadbolt and install the new one in it's place.
Answer: yes
