The safest and most reliable way to open a locked car door is to call a professional locksmith or your roadside assistance service (like AAA). Attempting to force the door open yourself can cause expensive damage to the door seals, window mechanisms, and lock actuators, often costing far more than a service call. If you must try a DIY method, using a specialized air wedge and long-reach tool is the least damaging approach, but it requires patience and carries risk.
Safety is the absolute first priority. Before anything else, ensure the car is in a safe location, not blocking traffic, and that there is no child or pet in distress inside. A hot car can become dangerous in minutes. If there is an emergency, such as a child locked inside, call 911 immediately. Do not hesitate; first responders are trained to handle these situations quickly and safely.
For non-emergencies, your best bet is professional help. A certified locksmith has the proper tools to unlock most cars without a scratch. Many modern cars with keyless entry systems can even be unlocked by the dealership if you have proof of ownership, as they can program a new key fob.
If you're in a remote area without cell service and need to attempt entry, the air wedge method is the standard. A small air bag is inserted into the top corner of the door frame to create a gap, then a long, rigid rod is used to press the unlock button or manipulate the interior door handle. This is a skill that takes practice. Never use screwdrivers or coat hangers directly as they will almost certainly damage the weather stripping and potentially scratch the paint or break the window mechanism.
The best strategy is prevention. Always double-check for your keys before closing the door. Consider keeping a spare key in a magnetic box hidden under the car or with a trusted neighbor.

Call for help. Seriously, just use your phone and dial a locksmith or your insurance's roadside assistance. I tried the coat hanger trick on my old sedan once, and let's just say the repair bill for the torn door seal was a lot more than the locksmith would've been. It's not worth the stress or potential cost to DIY it unless you're truly stuck somewhere with no other options.

Your primary concern should be liability and safety. Forcing a door open can compromise the vehicle's security system and door integrity. Most auto insurance policies include roadside assistance; using this service protects you from accidental damage. If a child or pet is inside, direct action may feel necessary, but emergency services are equipped to respond faster and more safely. The legal and financial risks of self-help often outweigh the inconvenience of waiting for a professional.

Been there, done that. My first move is always to check every single door and the trunk. Sometimes one is unlocked. If not, I call my buddy who has a AAA membership—they’ll help a member’s guest. If you’re on your own, a locksmith is the way to go. I’ve seen people use those inflatable air bags to pop the door open enough to hit the button with a stick. It looks tricky, but it’s a lot better than jamming a wire hanger in there and messing up your door.
