People accidentally lock their keys in their cars all of the time. In the event of a lockout there are many things that you can do:

1. Get a spare key. You can have a spare key made at your local hardware store. They are not costly to have made, so it is smart to get more than one key just in case you need them.

2. Leave the spare keys in safe places. Keep one in your house, give one to a family member, or give one to a friend that you trust. If there are people who have your spares, they can come and let you into your car if you are locked out.

3. Call the police. They can use special tools to let you into your car.

4. Have OnStar. You can call OnStar for help when you are locked out of your car and they will send a signal to your car and unlock it for you.

5. Call a tow truck to come and help you. This should be a last resort because it can be expensive.

6. Sign up with a good roadside assistance program that can help you in the event of a lockout. This is one of the best options because roadside assistance can provide you with a variety of roadside benefits, including lockout assistance.
