The invention relates to an anti-theft locking method and a digital anti-theft vehicle lock thereby, aiming to solve the problem that the existing vehicle locks are easy to lock-picked. The method of the invention comprises the following steps: two inserted-link lock catches and a spring lock for fixing the lock catch are used for locking; wherein, the spring lock mechanism for locks and a mechanism
cipher locking mechanism jointly lock a lock cylinder; anti-theft locking is realized by the method that two inserted links of the lock catch firstly pass through the through holes on a U-shaped relief cover and then are inserted into the lock body. The lock comprises an inserted-link lock catch for fixing car parts and a lock for fixing the lock catch, wherein, the lock comprises a lock core with a key hole and a lock body which is matched with the lock core via a bullet mechanismand has a U-shaped open slot; one side of the U-shaped open slot and adjacent two sides are matched with a U-shaped relief cover with fastening bolts by bolts, and the inserted link of the lock catch is clamped with a locking dog controlled by the lock core via penetrating the
side arm of the U-shaped relief cover and the through holes of the lock body; and the lock core is matched with a set of or two sets of mechanism
cipher locking mechanisms. The digital anti-theft vehicle of the invention comprises akey lock, a
cipher lock, a fixedly connected curb chain and a relief cover matched with the lock body, has the functions of preventing electric
drill, preventing prizing and sawing, preventing combination pliers, preventing smashing and preventing functional unlocking, has strong anti-theft performance, and is suitable for locking electromobiles, folded trolleys, motorcycles, vehicle steering wheels, etc.
