Diamond BLOCK built-in steering lock
No signal. No code. Just a locked steering wheel.
So your car stays where you left it.
Fully automatic: you don’t need to straighten the wheel before locking.
When locked, the steering wheel cannot be turned. The car cannot be driven away – even if a thief has opened and started it electronically. The lock sends no radio signal and has no code, so there is nothing to copy or jam.

Made for cars without a classic gear lever
Many new cars no longer have a traditional gear stick – they use a button, a rotary knob or a joystick. Diamond BLOCK was designed for them. It locks the steering itself and does not interfere with the car’s electrical system.
- Hybrid and electric cars
- Cars with joystick or button gear selectors
- Motorhomes, rental fleets and machinery – after an assessment
What you get
- Fully automatic – no need to straighten the wheel before locking.
- Purely mechanical – no battery to run flat, no signal to copy. Relay attacks and signal jammers cannot open it.
- Does not interfere with the car’s electrical system – so it cannot cause faults in it.
- Swiss KABA lock cylinder – keys cannot simply be copied; spare keys are ordered only through us.
- Almost invisible – only a small lock cylinder shows under the steering column cover.
- 5-year warranty, no monthly fees.
How it works
1. We install it
The lock is fitted to the steering column. From the outside you only see a small lock cylinder under the column cover.
2. You lock it
When you park, you lock the steering with the key. No need to straighten the wheel first.
3. The car can’t be steered
While it is locked, the steering wheel cannot be turned.

Price and installation
From HUF 200,000, installation included. We confirm the exact price for your car by email.
Installation takes one working day. If we get the car around 8 a.m., it is usually ready around 3 p.m. We provide a courtesy car for the day.
Frequently asked questions
My car already has a factory steering lock. How is this different?
On keyless cars the factory steering lock – if there is one at all, as many newer cars no longer have one – is usually released electronically: when the car detects the key or card, it unlocks. If a thief tricks the car’s electronics with a relay attack or a code reader, the factory lock opens too. Diamond BLOCK is purely mechanical – only its own key opens it; the car’s electronics cannot.
Do I have to straighten the wheel every time I park?
No. It is fully automatic – just lock it with the key.
Can it drain the battery?
No. It uses no power at all.
Will I lose the car’s factory warranty?
The factory warranty does not cover retrofitted equipment or faults it causes – the installer is responsible for those. We take responsibility for the Diamond BLOCK installation. The rest of the car remains under the manufacturer’s warranty terms.
