Abstract: The present invention relates to a combination and keyed bag lock with a pop-up hood. In one embodiment, a lock having a post and a rigid seat with a fixed rim is provided. A hood with a cylinder received within the post and an arm extending from the post is further provided. A key hole is within the cylinder. The arm of the hood houses a combination lock. A knob is rotatable relative the cylinder, and the hood pops up under actuation of the knob when the combination is accurately entered. The hood also pops up when the key is used to unlock the lock. The arm separates vertically from the seat when the hood pops up thereby allowing the body of a slide fastener to exit the lock.
