Use Our Tractor Air Brake Lock To Protect Your Unattended Tractor

The TAB-10 Tractor Air Brake Lock protects parked and idling tractors against theft by completely enclosing the trailer air valves and parking brake. 

Tractor Air Brake Lock Exterior

The WAR-LOK Air Brake Lock TAB-10 is made of die-cast aluminum, thus making it nearly impenetrable.

Tractor Air Brake Lock Interior

This device is designed to secure a tractor's air valve knobs by fully covering them. Its exterior is reinforced and includes two internal disks that detach and spin if someone tries to drill into the lock. As with all WAR-LOK products, the Air Brake Lock features a nine-cylinder disk locking mechanism, significantly reducing the chances of someone picking the lock and stealing the tractor.

Keyed Alike Tractor Air Brake Locks

Air Brake Locks can be keyed differently, keyed alike, or keyed alike to a master key. Furthermore, newly purchased locks can be keyed alike to an existing lock. WAR-LOK will verify ownership before any key is copied. Our keys are cut at our WAR-LOK Assembly Shop, located in Dallas, Texas, USA.

Installation and Removal

The WAR-LOK Truck Air Brake Lock is designed to fit standard air brake controls. Due to the various sizes and types of knobs used on truck brake control valves, please follow this procedure to set your Truck Air Brake Lock for the valve knobs in your vehicle.

1. Ensure the vinyl tips are installed on the Allen set screws.
2. Using the 1/8″ Allen wrench provided, adjust until the vinyl tip is touching the back of the knob. (This is a one-time adjustment.)
3. If using the standard red and yellow knobs, install the self-stick foam pads in the inner body.
4. If using the large chrome knobs, discard the foam pads.

To install the lock:
1. Slip one-half of the lock around the valve knobs.
2. Slide the other half until the two halves are together.
3. Push the lock button to secure the lock.

To remove the lock:
1. Insert the key into the lock cylinder and turn clockwise approximately 3/4 turn. The lock cylinder will spring extend to release the lock.

awesome product but doesn't fit certain trucks

I own this lock and used it for years. In their infinite wisdom, Freightliner sunk the air brake switches about a half-inch into the dash in their Cascadia model a few years ago, rendering the War-Lok useless. As a result, I had to return to using a lock that attaches to the steering linkage under the hood. This has the side benefit of making it convenient to inspect the engine, but the War-Lok is way simpler to attach and also visible to potential truck thieves, both of which are HUGE plusses.


Awesome extra security lock!


This air brake lock is without peer and will secure the truck with ease. It is extremely well made, easy to apply, and may be ordered keyed alike to other War-Lok locks whether at the same time or later. Very sturdy, substantial lock. Dave Reid

This is definitely a lifesaver they attempted to steal my truck they try to pry it with a screwdriver and realize with the amount of damage they will cause and too much time lost they will not get the truck so they just stole what's inside the truck. I will always do business with this company and I highly recommend them for their fantastic products
