The reasons why the co-pilot door cannot be opened from the outside are: 1. The central locking system of the door is activated; 2. The child lock is engaged; 3. The door lock cable is malfunctioning; 4. The door limiter is faulty; 5. There is an issue with the door or door lock; 6. The door has been subjected to external force, causing deformation of the door hinge and lock post. The solutions for a co-pilot door that cannot be opened from the outside are: 1. Replace the door limiter with a new one; 2. Lubricate the door hinge or lock with a lubricant; 3. Adjust the position of the buckle and gently pry it with a screwdriver until it fits properly. A car door consists of the door body, door accessories, and interior trim panels. The door body includes the inner door panel, outer door panel, door window frame, door reinforcement beam, and door reinforcement plate. Door accessories include door hinges, door opening limiters, lock mechanisms, inside and outside handles, door glass, window regulators, and sealing strips. Interior trim panels include the fixing plate, core plate, interior upholstery, and inner armrest.
I just bought a used car and encountered the trouble of the passenger door not opening from the outside. I found this is commonly caused by several reasons: rust or jamming of the door lock mechanism is the main cause, especially in older cars; if the child safety lock is accidentally activated, it prevents operation from the outside; when the door handle is loose or damaged, pulling hard won't help; on rainy days or in humid environments, the lock cylinder tends to stick; another major issue is the linkage rod breaking—mine broke because I slammed the door too hard once, and I had to replace the part. For prevention, you can spray some lubricant on the hinges and also check the fuse of the electronic door lock to prevent it from blowing. This problem is quite annoying and should be fixed promptly to avoid affecting passengers getting in and out. If all else fails, it's best to visit a professional shop early—safety first.
