Slipping a lock

Sep 20, 2014 21 Replies

Very common job with me, mortice latch on internal door fails in closed position, customer can't get into bedroom/lounge/etc. Good little earner.



I've always sorted it by prising off the slam strip and slipping the catch with a hacksaw blade. Trouble is in damages paintwork.



Came across this stuff the other day

In the past I've tried the old 'James Bond slip a credit card in', but it doesn't work. This stuff does. I've tried it on every door in Handyman Towers and it works an absolute treat! No more damaged paint work.



And now you have told the world about it...

I am glad I have chubbs...

No, I've told a little known newsgroup readership. Amazon have told the world.

I'm fairly sure that Amazon had that up prior to TMH posting. I'm off to find out on the interweb how to defeat your chubbs...

Bit over 2 mins seems average to defeat 5 lever Chubb

Angle grinder:-) Actually battery powered with diamond disc.

They're not familiar with the Super Hans solution then ?

An auto-deadlocking rim lock will also resist such an attack.

This will open one of them, easily

Indeed, but if you expected the people who legitimately wield those to turn up, you would make sure that the door is rather stronger than average.

I recall seeing one video of US Police trying to use the Big Yellow Key on a door of a suspected drug dealer. When that didn't work, they tried the windows, but couldn't get past the grilles and shutters. In the end, they had to knock a hole in a brick wall to get in.

I put it on uk.career-burglar but apparently they already know about it.

Any decent lock (one costing more than about £10) will be protected against that.

Large sheets of mica make great Rolf Harris wobbleboards.

Except that the better Chubbs have free revolving re-inforced rods in them. Besides whic an angle grinder is going to do so much damage you might as well take a fireman's axe to the door.

Yeahbut, we're not talking about Tim's door here...

I claim a patent on that!

Many years ago, our footpath users decided that it would be nice to kick off a fencing rail and save themselves about 50 paces. Some time later, ducking under the top rail proved too much so they took a saw to it. This potentially allowed my cattle to reach a busy road and the top rail was replaced with a length of 3" galvanised steel pipe. To discourage hack sawing, a free rotating length of 2" pipe was hidden inside:-)

I had forgotten you had bother with those sorts . . . . .

Top marks for the ingenuity with extra points for showing off with a 3" outer :-)

The hardened rollers in the bolt aren't unique to Chubb[1], they've been pretty much adopted as standard on all BS3621 locks. Not that it makes much difference these days, they were intended to protect from hacksaw attack and a thin disk angle grinder will take them out in short order[2].

[1] try finding Chubb for sale these days, you'll get redirected to Union, another Assa-Abloy assimilation, except for specialist locks. Nothing against Union though, still good quality. [2] not really giving anything away there, more encouraging people to put more barriers in the way of the bolt to slow things down

An answer to that might be an aluminium cover. The usual effect of trying to angle grind the stuff is smeared/melted aluminium clogging the abrasive.

'king expensive!

Lots of options available, mine is a multilayer approach, storm/porch doors with light security but alarmed with a transponder so that there is an alert before the proper attack starts.

Behind that, by all means use Alu reinforcement in your door stops. For a city centre app I have routed out a bit of the door stop to accommodate a 20mm steel angle and it made me feel a bit better about the installation.

Solid state shock sensor on the door jamb too for early notice of an attack but I realise the needs in the stix are different from the needs in the city.

I used Union even when Chubb was available and was perfectly happy with the security and value. One exception was when I wanted restricted keys which was only available on the Chubb.

I've also used a couple of 15quid budget BS locks to protect a tough door, they'd passed BS so will take a bit of abuse and the boxes have been ticked for the insurance company.
