Deadbolt for old door

[Evan]

Yup... Says me... It is the SAME size and durability bolt inside the door...

Double cylinder locks provide no additional physical protection than a single cylinder lock...

If the glass on or near your door is going to be broken to gain entry, then would it matter whether it is double cylinder or single -- everyone who advocates for the usage of double cylinder locks on residential doors always touts how they leave a key in the inside of the lock to facilitate egress, only removing said key from the door and hiding them away when they leave for a vacation... Are you seriously going to lie to me and represent that you go through that procedure twice daily before leaving for work and as soon as you return home ?

LOL... Sounds like your experience with your burglar was a local drug addict who had been in your home before and knew what to take that could be quickly sold and didn't bother trying to mess with anything else or attempt to open any of your double cylinder equipped doors... Your gun was not taken because it has a serial number on it which will be scrutinized whenever it is sold or transferred and then re-registered in the new owners name so it is not worth anything (other than a mess of state and federal firearms charges) to steal and wouldn't be stolen unless the crook personally needed a gun they wanted to keep and use for themselves... Also, that is how burglars get away clean from a house they have just burglarized, taking only what they can carry with them in a small backpack -- if they were carrying an arm load of pillow cases full of loot away from your house someone would notice that as being strange... Especially the police who would be responding to the intrusion alarm call at your home if you have an alarm system installed...

In and out in 3 minutes and gone... The only deterrent or useful home protection technology in that sort of common burglary is a centrally monitored alarm system which can alert the authorities within a minute or so of being tripped depending on how precise your alarm company's central station operators are when they are phoning your local police...

Your insurance company is only going to want proof that you took prudent security precautions in order to process any claim of loss on items you report stolen during a burglary... This means that you have locks installed on your doors and windows and your signing an affidavit saying that you had left them locked when you were away from your home... Signs of damage, no matter how slight are proof enough... So that broken window that a burglar used to enter your home is fine, your loss would be covered even if your entire home was emptied out your front door because the burglar unlocked it from the inside...

It is scary how many people there are out there like you who think that over-protection is better and turn their homes into death traps with double cylinder deadbolt locks which clearly neither prevent burglary nor provide any additional physical protection than a single cylinder lock... Do you really need to see the aftermath of what happens with double cylinder door locks to someone you know and love before you see how stupid a choice it is to install them?

Well, ackshooly, I haven't ruled anything out. At this point the best solution is looking to be the surface-mount Zeiss Ikon (Swiss-made) deadbolt that my local locksmith can sell me for about $100.

That very thought occurred to me as I was searching for such locks online. While you can get 2" backset locks, I guess there just isn't enough room to make a 1-1/2" backset lock with a long enough bolt.

It has a skeleton key lock. I did find a guy locally who rebuilds such locks, and can do it for a reasonable fee, but the homeowners are mainly concerned that the lock itself is fairly flimsy, so it would require replacement, not repair. And I have no idea where I'd get a *new* (to me) skeleton-key mortise lock; that'd be a huge can of worms.

I've checked with the best local place for such stuff (Ohmega Salvage in Berkeley), and they have nothing.

Hmm; first of all, I won't buy it unless the locksmith selling it can make me an extra set of keys, so I don't think that'll be a problem. And the lock itself is so simple, it's hard to imagine anything going wrong with it, short of someone taking a prybar to it or something. I don't see your objections above as problems.

Agreed.

I agree, and as you have read in my other posts, I insist on removing such locks for my clients.

Agreed; if a burglar is determined to get in, they'll just break the damn French door muntins out. Wouldn't take more than one good kick to do that.

Last I heard there were several building codes.

I have the equivalent of a key-in-knob lock and a double cylinder deadbolt on outside doors. The double cylinder locks on the main door are only locked if everyone leaves the house.

Two locks create more areas that have to fail to get through the door. The strikes are steel plate with long screws into the studs.

Burglars can remove what they take through the window they broke in through.

The main door has pins between the hinge halves. There are several ways to prevent defeat from hinge pin removal. I really doubt many burglars are going to remove hinge pins to get out of a house.

The lock cylinders screw into the mortise lock, and can not be removed without opening the door.

They do on my house.

A lot of security is making your house a less attractive target than others.

Both irrelevant.

Better to replace the lock of ur door may be it is in ur budjet, It will be replaced by Electromagnetic Rim lock, It will be a better choice....
