How to Fit a Disklok Steering Wheel Lock Properly (Step-by-Step Guide)
Car theft still remains a major concern throughout the UK at large, not least with modern keyless entry technology and sophisticated relay attacks. Whereas digitised protection can assist a little bit, nothing can compare with a strong visual and physical deterrent — which is where the Disklok Gold Security Edition can be found.
One of the most effective and challenging steering wheel locks on the market, Disklok offers complete protection if correctly fitted. But to be quite so effective, it must be fitted correctly.
Here in this guidebook, we walk you step-by-step through absolutely everything you'll need to know — from the right size right up to fitting your Disklok like a pro.
Why the Disklok Gold Security Edition?
It's a better concept even without the how-to to comprehend what makes Disklok stand out from any other wheel lock.
Where less high-end devices can do no better than disable a half wheel, the Disklok Gold Security Edition literally envelops your steering wheel in a virtually indestructible steel housing. It spins on impact, which effectively means it's nearly impossible for robbers of cars to gain a purchase or a grip of the wheel.
Key features include:
Double-walled steel enclosure
Full steering wheel coverage
Anti-tamper spin mechanism
Swarf castings become irretrievably identifiable with age
Hardness
Police and Thatcham approved
Lifetime mechanical warranty
Now, let's discuss how to properly fit it in — because if it's not properly fitted, security will not be very effective.
Step 1: Select the Correct Size
Disklok is available in three different sizes which are applicable for different steering wheels. Having the right size is necessary for security and ease of use.
Small: 35–38.9 cm steering wheel diameter
Medium: 39-41.5 cm
Large: 41.5–44 cm
To compute your wheel:
Measure the diameter using a flexible measuring tape (or with a string and a ruler).
Measure from centre edge to centre edge.
Match it with the corresponding size on the Disklok size chart.
Tip: For a close fit take the smaller size if your measurement falls between sizes.
Step 2: Be Aware of Pedestrians
Before fitting your Disklok assure your steering wheel is in the correct position:
Plain wheels
Horizontal steering wheel (in a usual resting posture)
None of these steering accessories (like phone holders) which may interfere with installation
Not only is the fitting made simpler but the alignment of the lock is correct thereby giving maximum security.
Step 3: Full Open Disklok
Turn your steering
The Disklok also has a clamshell design that is hinged using a split-opening mechanism.
To use it:
Keep the Disklok securely gripped with the handle.
Insert the key and turn it to the right to open.
Push the catch for opening the release on the front section.
Open the lock all the way so it's ready to slide over your steering wheel.
It's a good idea to keep the key in a safe but easily accessible place -- Disklok provides three keys for the unit, and we recommend keeping one at your house.
Step 4: Place the Disklok Across the Steering Wheel
With Disklok still in operation, slide it off your steering wheel's fore-end.
The larger half (handle side) is at the bottom.
The half of the hinge goes around the top.
Make sure it's totally encircled in the wheel — no part of the steering wheel can be exposed. It's essential the cushion be flat against the wheel at all times in case it moves around.
Hold for a moment to confirm it’s precisely in that position, and then you can easily unlock and lock it.
Step 5: Lock and Lock the Disklok
Seeded once in a place, it's fastened firm:
Turn the hinged half closed with a clicking firmness.
Insert the key if it's not already there.
Turn the key anti-clockwise until it clicks.
Take away the key and store it somewhere safe.
Try the lock with a small turn effort on the Disklok. It will turn without any leverage for steering manipulation for you. It's the free movement which prevents robbers from achieving leverage they need.
Step 6: Lock the Keys and Store the Lock
It also features a padded storage case for storage when not being used. It may be extremely large (around 4–5 kg), but most drivers actually do bring it along:
Behind the rear seat
In the boot
On the floor of the rear seats
For your protection at all times park with your Disklok deployed and keep the key somewhere which is out of your car keys' sight if the car is equipped with keyless entry. This minimises the chance of their being pinched together.
Maintenance Instructions for Long-Term Usage
It is It's long-lasting but a little bit of maintenance can keep it at its absolutely prime:
Wash it periodically for dust and dirt removal.
Don't throw it -- even firm blows can cause small dents.
Lube your lock mechanism regularly with a graphite lube.
Make sure to include the supplied felt pads to shield your steering wheel from small scratches or pressure marks.
Basic Fault Troubleshooting
1. It's hard to close the Disklok:
Check the size double. If it's too small or won't slide over your steering wheel at all, your steering wheel is perhaps smaller than the wheel cover's size can accommodate.
Remove any accessories in your way.
2. It won't rotate after it is locked:
Make sure it's not stuck fast against the dash or steering column. Simply tweak your steering wheel slightly and re-fit.
3. Lost your keys?
All Disklok's carry a unique key code stamped onto a tag. You can purchase a new one from Disklok itself using this. Never attempt to pry it open — you'll end up damaging your lock or your vehicle.
Why Fit Right Matters
A mis-fitted/loose Disklok can reduce its effectiveness – or better still, provide robbers with a simple way of removing it altogether. Properly fitted, it is one of the safest, tamper-proof deterrent devices available on the UK market today.
In conjunction with other safe parking methods and keyless signal protection, the Disklok is a worthy addition to your multi-faceted protection scheme for your vehicle.
