A vehicle anti-theft mechanism moves the driver's unit into a location which prevents operation of the vehicle. The mechanism includes a bracket mechanism that fits onto the driver's seat unit and has two screws that movably connect a first bracket cross arm to a second bracket cross arm. A motor operates the screws to move the cross arms toward and away from each other when activated by a programmable remote control. The first cross arm is connected to the seat unit and the second cross arm is connected to the vehicle frame adjacent to the steering wheel of the vehicle to be stationary with respect to the first cross arm so that operation of the motor will move the first cross arm toward or away from the second cross arm, thereby moving the seat unit connected to the first cross arm toward and away from the second cross arm. The second cross arm thus moves the seat unit toward and away from the steering wheel. To lock the vehicle, the seat unit is moved close enough to the steering wheel to prevent operation of the vehicle due to interference between the seat unit and the steering wheel.
