Question about multilock cylinders types

[verbal9]

Hello, I am new to this forum.

I have moved into a new rented appartment and I need to replace the cylinder. The lock is a multilock with a metal cylinder protection cap.



I have a low end cylinder which would fit this lock, I was wondering if I should use the low end cylinder or spend about 40$ for a cylinder simular to the one present now in the lock.

This the low end cylinder:


What is the difference interms of difficulty for a burgular? Is the extra 40$ really help slow the breakin attempt or not? Do burgulars realy pick multilock locks? Is there any difference in time when brute force is used ( drilling the cylinder)?

This question is a matter of principal.
I am not really so sheap or broke that I can't spend extra 40$

First thing you need to do is talk to the owner as you are not supposed to be messing with the building when you rent, everything has to go through the building superviser or owner,


Why are you needing to change the MTL?

I wouldnt use a cheap knock off for the sake of the extra money because youve no idea how strong the knock off is,

The MTL thats on your door maybe poart of a insurance deal with the owner so changing it for a none MTL will not only upset the owner but also invalidate the insurance he has,

Only some suggestions of what to look into, im sure there will be others that will come and give you better advice,

The legal stuff is take care of, the owner doesn't mind. I need to change the cylinder becase the previous guy who rent this appartment didn't return the keys and I have no idea where they are. (I have one key).
I what way do you mean "how strong" it is?
If you refer to physicaly breaking the cylinder inhalf inside the lock, that won't work because the cap prevents extraction of the broken cylinder.
Basicaly how much different is this knockoff from the real thing? Do people actualy pick multilock locks or do they use other means (brute force, windows, etc)

i have been in realestate for over 10 years and by law the leasor has to change the locks of any dwelling that has been rerented.

i have been in realestate for over 10 years and by law the leasor has to change the locks of any dwelling that has been rerented.

I was of the notion that the law on that differed from place to place. Does the same hold true between the US and UK?

[verbal9]

The law is different from country to country, I live in Israel.
Here there is no particular law about locks on rented property.
I have agreement of the owner and it is my problem since he doesn't care.

Can you please reply to the question I've asked?

[Wolfe]

the law is govern state by state in the US but remains constaint though out. I do not have much experience with the laws outside the US. UK has very strange laws like squatter laws so im pretty sure its not mandated that leasors must change the locks prior to a new tenant moving in.

You have remember practicality most thugs will not take the time to pick/bypass your lock when its faster to break a window or kick your door in. Even in the advent that you thug is smarter or more resourcful than the average thug picking is usually still out of the question and bypass would be the prefered method.

Unfortanatly i can't tell from the picture to well but from what i see the fact that you reside in apartments im guessing that you have a 3 in 1 lock which does not resist bypass methods very well.

But back to the original piont the better the lock the better protection
I hope this helps

Wolfe, thanks for your answer.

The lock is a multilock with 3 bolts (top, botom, hinge side) and 3 bolts in the normal position (near the handle). The door is steel plated. There are no bars on the windows (2nd floor).

However I am not planning on changing the lock, just the cylinder.

From the comments so far I figure its not a serious reduction in protection going for the knokoff cylinder.

[lunchb0x]

if someone still has a key that is a larger reduction in security compared to a cheaper cylinder, if it was my unit i change the locks the day i move in, so if you have permission to change the locks and mostly, you feel safe with it,then there is no reason why you shouldent change it

I thought Shrub made it quite clear that there CAN be a very appreciable difference security-wise when you use a knock-off..

It is impossible to compare the quality of the specific knockoff you have to the multilock on the door by just looking at the key. In my experience, knockoffs are most often much less secure than the true product. (There will of course be exceptions to this.)

For example, I have an Abloy knockoff, and a real Abloy, that use the same mechanism - the real abloy is just an old Classic, not newer generation.

I have yet to pick the real Abloy, I can pick the knockoff with pathetic ease, and just a couple wires, I have no 'more advanced' tools for Abloy.

Since the knockoff it seemed just TOO easy to pick, I decided to 'test' its tolerances.... so I started filing one of the keys down, deliberately trying to alter the key's bitting enough that it would not work. I changed the key's bitting a LOT before it wouldn't open the lock. Wish I knew where that knockoff is at the moment, it's worth taking a couple of pics just to show how poor it really is.

A good rule of thumb is that you get what you pay for.

As lunchb0x said, use what YOU feel provides an adequate level of security. I wouldn't choose the installed multilock, given its key is compromised.

mercurial,

I understand that the knockoff might not be as good. As far as I understand the only way to know if it is worst is to try and pick it, which seems unlikely for me and my n00b level.

For overall grading I am considering that people on the forums told me about the fact that burgulars rarely pick locks and prefer to use force intead.

If they use an angle grinder on the door to cut out the lock or a pneumatic jack to force the door frame apart there doesn't seem to be any difference on the use of a cylinder.

I don't know if these types of lock have bumpkeys for them (mutlilock or the knockoff) but I've read that with bumpkeys a poor quality lock might be prefered since it the pins are more likely to jam.

Some knockoffs are so easy to pick that you might be able to pick that cylinder. The most likely obstacle to that is you probably don't have the picks that are used for MulTLock type cylinders.

Absolutely - burglars rarely pick locks - brute force(to the door or any other point of entry), and somehow obtaining a copy of the key would be the most common means of entry.

I don't know if these types of lock have bumpkeys for them (mutlilock or the knockoff) but I've read that with bumpkeys a poor quality lock might be prefered since it the pins are more likely to jam.

I would be almost certain that the knock-off you have can be bumped, but unless this same knock-off cylinder is widely used where you are, it would be very unlikely the burglar would have a bumpkey to fit the lock.

It is true that some very low quality cylinders resist bumping due to their extremely sloppy tolerances and it is true that pin-tumbler locks that are built with better tolerances are often a lot easier to bump compared to cheaper locks. The better tolerances help to smoothely transfer the impact energy from the key, through the bottom pins to the top pins.

Personally I wouldn't use the cheaper cylinder for bump resistance. A real MulTLock(and high-security cylinders in general)has anti-drill inserts, and a drill is more likely to be used than somebody taking an angle-grinder to the door.

or just have the old one rekeyed.

There is a tecnical problem. With these lock you have a Mul-t-lock with a gear cam. You can't change with a normal cam. You must have a cylinder witch have a gear with the right number cog.
