If your car is locked with the keys inside, the fastest and safest method is to use a spare key. If that's not available, your next best option is to call a professional locksmith or your roadside assistance service, like AAA. They have the proper tools to open the door without damaging the vehicle. Attempting to use improvised tools like coat hangers can easily scratch the paint, damage window seals, or even trigger the airbags, leading to expensive repairs.
The specific steps you can take largely depend on the type of key system your car uses. For traditional keys, a locksmith can often create a new key on the spot. For modern cars with keyless entry fobs, the situation is more complex. The key fob contains a chip that communicates with the car's immobilizer system; without it, the car won't start even if you get inside. Some vehicles, like certain Tesla or General Motors models, offer a mobile app that can unlock the car if you have an active connected service subscription.
It's always best to be prepared. Consider getting a magnetic key lockbox that attaches to a discreet part of your car's frame to store a spare key. Alternatively, a faraday pouch or signal-blocking bag can prevent relay attacks that might lock your key fob signal inside a modern car.
