Run Lock

Run LockRun Lock is designed so that a vehicle can be left with the engine running to power radios, lights and other ancillary devices without the battery going flat. If anyone tries to drive the vehicle without re-inserting the ignition key, the engine will stop. This allows vehicles to be left running without the worry of an unauthorised person driving off or entering the vehicle.
