Using a coat hanger to open a car door is a classic lockout method, but it's far from a guaranteed or safe solution. It primarily works on older vehicles with traditional lock posts (the button-on-stalk type) rather than modern cars with complex electronic locks and sealed windows. The goal is to maneuver the straightened hanger through the top of the door frame to press the unlock button or pull the lock tab.
First, you'll need to create a tool. Straighten a wire coat hanger but leave the hook intact. You can also fashion a small loop at the end to provide a better surface for pulling. The critical and most difficult part is creating a gap between the door and the car's body. You can try gently wedging a blunt object like a wooden doorstop or a rubber wedge into the top corner of the door frame. Never use a screwdriver, as it will damage the paint and door seal.
Once a small gap is established, carefully work the hooked end of the hanger through the weather stripping. This requires patience and a delicate touch to avoid damaging the door's interior components or the wiring housed within. Maneuver the hook down toward the lock mechanism. If your car has a vertical lock post, try to hook it and pull up. If it's a horizontal power lock button, you'll need to use the hook to press it.
Risks and Recommendations:

Honestly, I’ve done it on my old pickup truck from the ‘90s. It’s a frustrating ordeal. You’re fumbling with a piece of wire, trying not to bend it too much, and praying you don’t scratch the interior. It worked eventually, but it took forever. On my wife’s newer SUV? Wouldn't even try. The locks are flat and electronic. Save yourself the headache and just call a tow truck or a locksmith. The cost is worth avoiding the potential damage.

This method is a last resort and carries significant risks. The primary concern is causing expensive damage to your vehicle's door seals, window edges, and internal wiring harnesses. Modern vehicles are particularly vulnerable. Furthermore, attempting this on a car that is not your own is illegal and considered break-in theft. Always evaluate the situation; if you have roadside assistance on your insurance policy, using that service is a far more prudent and secure option than attempting a DIY entry with a makeshift tool.
