Padlock types
The main choice issues with padlocks are security, corrosion and cost.
Miniature padlocks
- Trivially easy to open without the key
- Good for non-secure access control
- At the bottom of the market, other samples may use the same key as yours
- Little security
Iron padlock
- Tough, but rust prone.
Brass padlock
- Rustproof, but not so tough
Colour coded padlock
Shutter lock
- Straight hasp, C shaped body
Stainless steel shackle
- Harder to cut
Aluminium body
- Lightweight lock, low security
Laminated padlock
- Body made of sheet metal stampings rivetted together.
Cheaper to make than a cast lock
Stainless steel interior
- For use in severe weather
Marine grade
Disc padlock
- Hard for a cutting tool to get a good grip on the rounded shape
Heavy duty padlock
Wall anchor
- Floor or wall fixing padlock for bike securing
- pic
Combination padlock
- Keyless
- Some users forget the pass code
- Some users fail to change the pass code
- Slower to use
- Vulnerable to shoulder surfing
Shoulders
Built up shoulders reduce the vulnerablity of the hasp, but have no effect on the more vulnerable parts of the lock
Options
Keyed alike
Keyed alike padlocks share the same key pattern. Your batch of keyed alikes will have a different key pattern to someone else's batch.
Master keyed
These padlocks each have their own key pattern, but are also all openable by a master key.
Thatcham approval
Insurers may require a thatcham approved locks be used for a vehicle, otherwise the insurance policy is invalid.
Attack modes
Padlock security is low as they're easy to open. The main padlock attack modes are lock picking, cutting & shattering. Combination locks are also vulnerable to pass code guessing and dictionary attack.
In many cases the item the padlock is attached to is targeted instead. Standard basic hasps are more vulnerable than a half decent padlock. Using security screws can help to an extent.
