There are few things more frustrating than locking your keys in your car. You could be stuck in a parking lot or out running errands. You may be late to an important appointment, like work or picking your kids up from school. It's possible that you may have a spouse or someone else who has a spare key, but they may not be able to bring it to you at that moment. What do you do?

If you're frustrated enough, you may be tempted to break the window. While that could be appropriate in emergencies, it may not be the best solution. A broken window isn't cheap to repair, and it could make the car uncomfortable to drive. There are a few other steps you may want to consider first. Below are three options if you lock your keys in your car.

Pry the door open and use a rod. If your car has an unlock button on the inside of the door, you may be able to break into your car without breaking the window. You'll need something to pry the door slightly open. A blood pressure cuff is often effective. Granted, you probably don't carry a blood pressure cuff with you, but if you're near a grocery or pharmacy, you may be able to purchase one. Slide the deflated cuff into the top of the door and start to inflate it. The cuff should create a small gap between the door and the roof of the car. Slide a long thin rod in the gap and use it to press the unlock button. 

If you don't have a blood pressure cuff available, you could use other items to wedge the door open slightly. For example, a screwdriver or door wedge may work. No matter what you use, be careful not to create too big of a gap as that could damage the door. Only create an opening large enough for the rod.

Call the police. Many local police departments have tools to unlock a door. Of course, their availability to do so depends on a number of factors. If it's late at night or you're in an unsafe area, they will likely be willing to help. If there is a child or pet in the car, they will almost certainly help. In fact, if there is a child in the car, calling the police should be your first step. 

Contact a roadside locksmith. If you can't break into your car and the situation doesn't warrant the police, you may want to contact a roadside assistance locksmith. They're usually available through roadside assistance services. However, many locksmiths also offer standalone roadside service. Look up local locksmiths on your phone and contact a few in the area. They'll be able to use specialized tools to get your door safely open and get you back on the road as soon as possible.
