Does a lock like this exist?

[DLM1166]

Hi, I know most if not all locks can be picked but I at least don't want to make it easy for someone to get in.

I am looking for a surface mount jimmy proof type of lock that only locks/unlocks from the inside and does NOT have a cylinder for a key on the outside. Do they even exist because I cannot find one anywhere online.

I am not concerned about theft when I am not there, I am more worried about my safety when I am home alone. My Giant Schnauzer is living with his Dad so I need to upgrade my door locks.

Thanks in advance for any advice.

Could you just use a regular jimmy proof deadbolt, and not install the cylinder? I would also take extra measures to secure it properly, as the screws supplied sometimes are not sufficient.

I think this is what you are looking for

I don't know if you're in the US, and if so whether or not these are common there, but you can get the kind of mortice locks that fit in through the edge of the door (similar to a mortice lever lock), with a round bolt and will all open with the same key, they're not susceptible to latch pulling tricks and can be drilled in to access only from inside.

They're normally pretty cheap, too.

Kwoswalt99 I was wondering that myself. I haven't been able to find that info either so I think I have to call the manufacturer directly.

Blue60. Yes I have seen these but was hoping to find something a little more substantial.

LocksportSouth. I am in the US. I was hoping to find a surface mount so I could install it myself but this would be an good option otherwise.

They can be installed without the cylinder. What kind of door are you securing?

You could install this yourself, just need a chisel, hammer, and screwdriver

*just skip installing the lock cylinder that would be on the outside of the door.

In addition, if you wanted the round ones I linked, they can be installed easily yourself. You just need one of those drill bits with the wide flat head (made for boring holes). (Looks like This - you should be able to get one from your local hardware place). All it needs is one hole drilled in with that tool the depth of the lock body, and then a second smaller hole to line up with the keyway (measure from the front of the lock to the hole on the body, then measure that distance on the door and mark a point to drill). If there is very little clearance between your door and frame you may also need to use a chisel to cut in a little notch for the plate at the edge where the bolt comes out but if you have more than a couple of mm gap between the door and frame you don't even need to do that .

FYI, those are commonly called spade bits.

Ah, so they are . Thanks!

It looks like those two links are the same?

There are deadbolts that do not use a key way (or anything else) on the outside of the door. At one point I think they were required on apartments in Texas (they were mounted up high so little kids could not lock themselves in). It would involve hole-sawing part way through the door. Either solution is going to require some wood work, even the surface-mount would require some chiseling to inlet the part that goes on the door frame as Squelchtone pointed out.

If the original poster is not interested in doing some wood work, might be a good idea to get a price from a professional. A professional could also put in some security pins in an existing lock to make it bump and pick resistant and strengthen the door jam to prevent someone from kicking in a door, which is much more likely than someone picking a lock. One could best ask about how to best find professional locksmiths in the locksmith forum on the site?

kwoswalt99, Squelchtone - That's what I was hoping, thank you! I am securing my front door which is metal. I also have a back door I need to secure but it's a different problem; It is set into the door frame so the inside of the door is not flush with the wall but the outside of the door is, so in that case I would have to have a regular deadbolt I think. Right now the only locks on all my doors are doorknob locks, including the one that goes to the attached garage. Pretty bad I know. Not to mention there is patio slider. The house is like an invitation to come in.

LocksportSouth - Would these be able to be installed in a metal door? I assume so but wonder if that would require me to hire someone to do it.

Jacob Morgan - That's what I thought too but cannot find them. I thought I remembered having one in an old apt. I had but I'm not sure now. I'm pretty handy with tools so I'm going to give it a try first using a surface mount lock since it's a metal door.


Thank you everyone for your advice! This is a great forum.

No idea, sorry. I've only ever installed it in a wooden door. Seems like it would be a lot more work in a metal door TBH. Someone else may know more.
