The quickest way to gain entry to a locked new car is to call a professional locksmith or a roadside assistance service like AAA. Modern vehicles with complex electronic locks and laminated glass make DIY methods not only ineffective but also likely to cause costly damage to doors, windows, and security systems. The core advice is to avoid forceful attempts and seek professional help immediately.
Attempting to pry a door or break a window on a modern car is a bad idea. Doors are designed with tight seals, and windows are typically made of laminated glass, which is extremely difficult to shatter completely. Using a coat hanger or slim jim is also largely obsolete. Most new cars have electronic lock actuators and shielded window frames, meaning there's often no physical linkage to hook. You're more likely to scratch the interior, damage wiring harnesses, or trigger the alarm system.
Your first step should always be to double-check all doors and the trunk. If you have a key fob, check if the battery is dead; sometimes holding the fob directly against the door handle can trigger a low-power signal. If you're stranded, the safest and most cost-effective solution is to call for help. Roadside assistance plans often cover lockout services, and a professional automotive locksmith has the specific tools to decode the lock or program a new key on the spot without damaging your vehicle.
The table below compares the outcomes of different entry methods, illustrating why professional help is the only recommended choice.

| "Slim Jim" Tool | Very Low | High | $500+ (for damaged lock mechanism) |
| Breaking a Window | High | Severe | $300 - $1,000+ (window replacement + cleanup) |
