Thieves choose the easiest car on the street. Make sure it isn't yours.
A visible, Sold Secure-rated bar turns a 60-second theft into a noisy, tool-heavy job — so the thief moves on.
What actually happens
Most vehicle theft is a selection problem: a thief walks or drives a street — including the worst streets our police-data pages name in every town — and picks the car that offers the least resistance. Electronic attacks (relay, OBD programming) beat electronic defences silently; what they don't beat is hardened steel physically preventing the car from being steered.
The deterrent works before the attack even starts: two identical cars, one with a bright bar across the wheel, and the choice is made in seconds — against the protected car.

What to buy — the checklist
- ✓Sold Secure Diamond or Gold rating — the independent attack-test standard that separates real locks from theatre
- ✓Full-width bar designs beat small clamp styles — visibility is half the product
- ✓Check fit for your wheel thickness, especially on airbag-heavy modern wheels
- ✓Practice fitting it — a lock that's a hassle stays in the boot; a 10-second habit protects nightly
- ✓Bright colour is a feature, not a style choice: it must be seen from the pavement

What changes once you own it

Asked before buying
Can't thieves cut steering locks off?
Given time, tools and noise, most physical security yields — but that's the wrong test. Attack-rated locks take minutes of loud, conspicuous work, and street thieves operate on seconds of silence. The lock doesn't need to be uncuttable; it needs to make the car next to yours the better choice.
Which rating should I look for?
Sold Secure is the independent benchmark — Diamond is the highest attack rating, Gold below it. Unrated locks can be bent or picked in seconds and mostly sell paint, not protection.
Is it worth it on an older car?
Often more so — older cars lack immobiliser sophistication and are stolen with basic methods a physical lock directly blocks. It's also the cheapest insurance-excess protection an older car can buy.
