Best garage door locks and security | Lock it, don't lose it!

Updated: 29 July 2024

It’s almost universally agreed that the best defence against bike theft and the most secure way of storing your motorcycle is a locked garage – but even then you need to consider additional garage door security.

But that doesn’t mean even that is 100% safe or that there aren’t further measures you can take to make your garage impregnable. After all, a garage is only as secure as the door and/or lock it’s fitted with.

Which is why, aside from motorcycle locks and other security measures for your bike itself, such as GPS trackers, alarms and immobilisers, which should all be considered, there is also a range of garage door security such as defenders or locks available, which are designed to bolster the strength of your door.

These range from stronger locks for the door itself to lockable barriers or defenders which prevent the door being opened to extra internal barriers which can prevent a bike being removed even if the door is opened.

But what’s out there? What do they provide? How do they work and what do you get for your money? Here’s our pick of the current best to help you decide…

Best garage door security

Bulldog Garage Door Lock

Price: $98.80

View Offer

Here is a simple but straightforward and reasonably affordable garage door security solution to start off with. This heavy-duty security L-shaped bracket with inclusive lock simply bolts to your door with the locking barrel cemented into the ground.The bracket’s made of 6mm steel, there’s a hardened-steel lock bolt, it’s highly rated, brightly painted so is a visual deterrent too and works well enough, although it’s not as large and extensive as some garage door security.

Pros

Great value for money and is much stronger than your standard garage door locks
Very secure locking device if you don't mind a bit of effort installing
Mid-range price so is affordable for good peace of mind
Really strong and highly visible deterrent

Cons

There’s a cover but rain can get into the lock
The depth of the 'indentations' in the key hole are not quite as varied as could be
Requires some drilling and needs to be cemented into the ground

Dimensions	‎14.2 x 7.5 x 8.6 cm; 1.36 kg
Construction	Steel
In the pack	‎Plate, lock and bolts

Not an added barrier, per se, this is instead a replacement or additional locking bolt system which comes as a pair, attaches to the inside of your existing door and then, when the bolts are extended into the door frame and locked, give a much greater level of locking security to your existing garage door.

This way you get more security, at an affordable price and one that also doesn’t change the visible ‘look’ of your door – although a counter argument to that is that it provides no additional visual deterrent.

Pros

Affordable price for locks that last a long time if fitted properly
Gives extra peace of mind about security of your garage
Would cause a thief a lot of noise and commotion trying to get through them
Bolts goes into the ground or wall at least 4 inches so quite secure

Cons

Can be fiddly to fit but are worth the effort
If you're not a DIY person you might have to get a locksmith or handyman to fit

Dimensions	‎22.6 x 8 x 5.9 cm; 1.42 kg
Construction	‎Alloy Steel, Metal
Included	‎Screws, Key

Hardened steel latches

Pros

It's a well made device constructed from good, solid metal

The padlock is exposed to the elements so get one that doesn't rust over time

It’s fully ‘dip’ galvanized and also powder coated with a red finish. The barrier end caps this time are plastic and the design has a tamper-proof ‘tunnel’ or compartment for the padlock.

View Offer

Here is a more premium, heavy-duty lockable garage door defender that although at a slightly higher price compensates for this by having the Sold Secure security approval rating.

Pros

"Sold Secure" seal of approval for peace of mind
Complete with lock and lock ‘tunnel’

Thieves would have to make a lot of noise with drilling and hammering to get past this lock

You do need some DIY skills involving heavy drilling and potentially concreting

Included	Bolts, lock, padlock and key

Powder coated finish
'Sold Secure' approved
