Securing shed doors: What sort of lock?

zoothornrollo_2

So our new shed has the sort of door that closes with an overlap - ie. not a flush surface, as pictured below. You'll see it already has an internally fitted lock. But it will contain two bicycles, at front of house, so would like it quite secure.
My first thought was to fit two hasp and staples, top and bottom. But the ones that have a second hinge to cope with uneven doors just seem to me an invitation to insert a crowbar? Is it possible to fit them ina way that doesn't.
For the moment I've ordered one hasp and staple of the standard sort, with one hinge, hoping that it'll be possible to get the hasp over the staple sufficiently to get my No.39 Squire padlock into it. And go from there.
Any other tips on best locking solution would be appreciated.

How much are the bikes worth?

The problem with security is the more you do to make a building secure, the greater the temptation to passing folks to break in on the off-chance something valuable is inside.

No matter how good the hasp, staple and lock, the timber planks are vulnerable to being prised off with a screwdriver or small crowbar. So spending money on top of the range door furniture security is pointless if the walls (and door itself) are not upgraded to prevent access that way instead.

If the bikes aren't high value, then personally I would go for low-grade door furniture but fit decent locks on the bikes, ideally secured to an anchor point fixed firmly to the floor.  I.e. Let people look inside your shed if they want, but make it difficult for them to take the bikes. The heavy-duty base of the shed gives you an ideal attachment point for an anchor.

If the bikes are high value then you'll need to consider doing both - keeping people out of the shed and making it difficult to take the bikes once they get in.

If you do try to make the shed properly secure then the door furniture needs to be fitted with security screws, or preferably coach bolts with the head on the outside.  There's no point fitting hinges or locks that can be bypassed by undoing the screws.  Given you might have planning issues with the shed, I would avoid security screws as they would hamper dismantling and relocating the shed. If used as suggested, coach bolts are easily undone from the inside.

Alarm padlocks are also available, but best used on items inside the shed rather than on the door.  They are sensitive to movement and being on the door could result in the alarm going off in wind.

Do remember there is no lock that cannot be opened in under a minute by anyone determined enough. (yes some require special tools).

I would just use a hasp top and bottom with a padlock. Unless it’s some super-shed, it will take a thief 3 minutes with a screwdriver to undo the door hinges and get in anyway. That’s how I got into my old shed when I accidentally left the padlock keys hanging inside!

To make the bikes more secure I’d suggest installing something inside the shed they can be locked on to.

Completely pointless, unless the walls are strengthened and upgraded as well.

Standard bolt croppers will deal with it in less than a minute, the design is appallingly bad. Also because it will be really inconvenient for the owner in normal use.

Meanwhile, you may as well buy a sign saying "Valuable stuff worth stealing kept in here" and screw that on the door too.

It will deter the chancers but not the professionals.

This will also deter the chancers, far more discretely, and at less than 3% of the cost -

Going to state the obvious here but if you have tee hinges you need to either change the screws to tamper proof or drill them out!

Whatever lock you put on it that shed is not overly secure. Use it to keep the bikes out of site and fit a ground anchor and chain. Depending on the value of the bikes an alarm padlock or a shed alarm could be good.

Couple of bits of threaded rod about 3 to 4 foot long,hammer about 1 foot into ground, oversleeve with a bit of 4" duct to whatever height suits then some suitable chain dropped down duct trying to get rod through links of chain and fill with concrete.
