Prime-Line U 9970 Deadlock – Jimmy-Resistant Design Prohibits Forced Entry by Spreading of Door Frames – Single Cylinder Diecast Metal Lock With a Brass Finish and Angle Strike (Single Pack)

Very solid easy to install lock. Heavy duty this was easy to install, it fit the doorframe perfectly and it functions as it should. Great lock, great price!

Awesome lock! I feel so safe.

This replaced a stainless steel Segal lock that looked same as this one. The four long screws went over the old Segal at exactly the same positions, but the height of this new lock is a little shorter than the old one, so there is a little space between the door and the base of this lock. It is not a perfect fit but I use this lock for added security only, I do not use the keys that came with it, as this door has another main lock with key. I also had to use my old strike plate or called latch?, because the strike plate/latch that came with this lock is a 90 degree L-shaped one that does not fit over my door frame/molding which angles inward, not 90 degrees. Make sure to ask for the proper strike plate/latch before ordering. So, I have a brass colored lock with a steel colored receiving end latch; alittle funny looking but I don't want to bother with the return right now because the lock works just fine. I wish they had advertise which strike plate they were selling to begin with though, otherwise the lock is very good, smooth, quiet and very affordable.

My Dad installed this lock at least 20 years ago. It finally quit working. The cylinder would turn but the locking mechanism would not engage. It was not available locally at the 3 places I checked so I went to Amazon to get it. It is just like the old one and fits exactly. This made it easy for me to install with no problems. The door is 70 years old. If this new lock quits working, I will probably have to replace the door instead of the lock. Glad I found it on Amazon, and really glad the style has not changed since my Dad bought the first one. Recommend it for durability and safety. If you are installing it on a door that has never had a lock like this, it will be more complicated. I am not that skilled. The instruction are very clear and explain how to do it, and templates are included.

Replaced an old, same style, one side keyed lock with inside knob lock on a door with upper glass. Easy to install, great instructions.

I recently needed, on a very short time fuse, to replace this kind of lock on an outside door to my house. The old lock must have been at least 40 years old. To my very pleasant surprise, exactly the same kind of lock was readily available on the Amazon website. Had exactly the same mechanism, dimensions (including mounting screw holes), and door frame pieces. I had to work to remove the mounting screws for the old lock, but installing the new lock was a very simple task after that -- no new drilling! Had to replace all of the old keys. But otherwise this was a WOW!

Cheap

My old lock stopped working after 30 years. I did not feel like taking it apart to fix the inside lock. This was a perfect match and fit in the same space including the holes for the screws. The weight was slightly lighter than the original but just as sturdy. The keys turned easily on both sides with no pressure. Security reinstated... The local hardware stores were either sold out or double the price. This was worth the short wait.
