Stop Vehicle Thieves Before They Start
Every year, thousands of vehicles disappear from driveways, parking lots, and city streets — often in less than 60 seconds. A visible deterrent stops most attempts before they begin. This adjustable anti-theft steering bar combines a high-security copper cylinder lock with reinforced steel construction, creating a formidable physical and visual barrier that forces criminals to look elsewhere. Install it in seconds, store it anywhere, and rest easier knowing your vehicle carries professional-grade protection wherever you park.

Why You Need This
- Advanced Lock Cylinder: Pure copper mechanism with multi-spring design resists picking, bumping, and unauthorized key copying — far beyond standard pin systems.
- Fits Nearly Every Vehicle: Adjustable from 11 to 26 inches to secure compact sedans, full-size SUVs, pickups, and crossovers without adapters or modifications.
- Built-In Glass Breaker: Hardened steel tip shatters side windows in emergencies — flooding, accidents, jammed doors — turning your security device into a lifesaving rescue tool.
- Deploy in Under 10 Seconds: One-handed pull-and-lock operation gets you secured and on your way without keys, codes, or complicated steps every time you park.
- No Interior Damage: Foam padding at every contact point protects leather, vinyl, and synthetic steering wheel covers from scratches, pressure marks, and daily wear.
- Hydraulic Cutter Resistant: High-strength steel bar withstands the cutting tools commonly used in vehicle theft, adding critical minutes that thieves simply don't have.
Built for Real-World Security
Whether you're parking overnight on city streets, leaving your vehicle at the airport, or simply adding peace of mind to your daily routine, this anti-theft bar delivers robust protection without hassle. The bright finish and substantial profile announce its presence from outside the vehicle — a proven deterrent that research shows dramatically reduces theft risk. When stored, it collapses to just 11 inches, fitting neatly in your glove box, door pocket, or under the seat. And with the integrated emergency breaker, you're prepared for the unexpected.

What Our Customers Say
Discover what makes THOMLER special.
Fits my truck perfectly without any fiddling around with adapters or extra parts needed.
Nice to have the glass breaker feature even though I hope I never actually need it.
Takes about ten seconds to install and remove, which is exactly what I was looking for in a steering wheel lock. Padded grips don't leave marks on my leather wheel either.
The adjustable range means it works across all three of our vehicles without buying multiple units, and it stores away cleanly in the glove compartment when we're not using it.
Honestly impressed by how substantial this feels compared to cheaper alternatives I've seen at box stores. The copper lock cylinder mechanism has real heft to it, and the steel bar doesn't flex or rattle when tightened down.
