Safe Methods to Open a Locked Car

If your keys are locked in a car, don’t panic. There are several approaches to unlock car doors safely, depending on your situation and the type of lock your car uses.

1. Call an Emergency Locksmith

A certified emergency locksmith is trained to unlock a car door without a key using specialized car door unlocking tools that prevent damage. They can also make a new key on-site if needed.

Sure Lock & Key provides car unlocking service across the U.S., helping drivers get back on the road quickly and safely.

2. Contact Roadside Assistance

If you have a roadside assistance plan, call them for help. They often work with professional locksmiths or dispatch their own car lockout service to your location. But this isn’t a good option if you’re not in a safe place and can’t wait for help to arrive.

3. Use a Car’s Remote or Companion App

Many newer vehicles include remote unlocking features or smartphone apps. If your phone is synced to your vehicle, you may be able to get into a locked car within seconds.

DIY Techniques (Use with Caution)

If you’re far from help and need to unlock a car door urgently, there are a few DIY tricks. However, these carry risks of damaging your locks or paint.

Wedge and Long-Reach Tool Method

This method uses a plastic or inflatable wedge to create a small gap between the car door and frame. A long, thin rod (often part of car door unlocking tools) can then reach inside to press the unlock button. This is similar to what professionals use, but without training, you could scratch the paint or break a sensor.

Shoelace or String Method

This old trick only works on manual locks with a “pull-up” pin. You tie a loop in a shoelace, slide it through the top corner of the door, and pull it tight around the pin. It can work on older models but is ineffective on modern vehicles.

Slim Jim or Coat Hanger

A slim jim or wire hanger can move internal lock mechanisms, but this method is outdated and risky. Modern car doors have airbags and sensors that can easily be damaged. If your car uses electronic locks, this technique won’t work.

When to Call a Professional Automotive Locksmith

Trying DIY methods can be tempting, but if you’re dealing with locked keys in a car or a complex system, calling a professional is usually the safest and fastest choice. Licensed technicians from Sure Lock & Key use advanced car door unlocking tools that protect your vehicle’s wiring and locks.

Professional locksmiths can:

Open your car safely in minutes.
Cut and program new keys if you’ve lost them.
Offer car lockout service and ignition repair if needed.
Provide auto lockout help through emergency response teams.

This approach not only saves time but also prevents damage that could lead to costly repairs later.

How to Avoid Getting Locked Out Again

Once you’ve solved the immediate problem, it’s worth taking steps to prevent future lockouts. Keeping a spare key, using smart keychains, and setting phone reminders can save you a lot of trouble later.
