Now that you’re inside, here’s how to start your car with a dead key:

Step 3: Put the key blade back into the key and close it.

Step 3: Put the key blade back into the key and close it.

Use the key to press the START button. Instead of using your finger as usual, press the button key. This is a backup system that many manufacturers use to ensure that the car starts even when the key is dead.

In some vehicles, the engine can be started using a hidden key socket. For example, some Ford models have a spare socket inside the cup holder. The socket is the perfect size to hold the key. Insert the dead key into the slot, then use the start button as usual.

If both of these methods don’t work, check if there is a physical hole in the steering column for the key (some Mazda models have this feature). Insert the key blade into the hole to start the car.

Other Ways to Unlock Your Car

Access your car remotely.

If your car has an app, use it to unlock your car from your phone. Once primarily a luxury feature, most automakers now offer an app. The FordPass Connect app, MyMazda app, myChevrolet mobile app, and Toyota app all let you unlock your car doors from your phone. You’ll need to set up these apps before your key dies, and some remote services may charge a monthly fee.

Come closer.

If your key doesn’t work at a typical distance, the battery may simply be weak rather than completely dead. In this case, the car may unlock if you get closer. Place the key right next to the door handle and press the unlock button.

Call roadside assistance.

If all else fails, call for help. Before you get into trouble, check if your insurance covers roadside assistance, then save the number to your phone. Keep a second copy in your purse or wallet in case your phone runs out of battery (or gets locked in your car!).
