Give would be thief’s a visible sign that you mean business and that your vehicle is secured with our high quality steering wheel lock. Simply insert the key, turn it counter-clockwise to lock, place the base hook in the steering wheel, pull the end hook out till it fits snug against the other side of the steering wheel, that’s it! To unlock insert key, turn clockwise and push the end hook back into the body of the unit. Since the locking mechanism uses a quad style key to protect against lock picking make sure the notch in the key is facing the dot on the lock. This will ensure the key is inserted properly. We suggest keeping the unit locked when not in use to prevent the end hook from coming completely out of the body. Maximum span for this lock is 14 inches. When fully extended overall length is 26. 75 inches. Collapses down to 19. 25 inches in total length. Will not work on steering wheels with a thickness larger than 1. 25 inches. Includes 2 keys.
