What to Do When You See the Car and Lock Symbol on Your Dashboard and Your Car Won’t Start

If you see a car and lock symbol on your car dashboard, it means that the car won’t start. This is because the system has detected an issue with the immobilizer, which is responsible for preventing theft by disabling the engine unless the correct key is used. The immobilizer uses electronic chips embedded in the keys to authenticate that the key belongs to the car, and when this authentication fails, it will prevent the engine from starting. In order to fix this issue, you will need to have your vehicle checked by a mechanic who can diagnose and repair any problems with the immobilizer system.

Checking the Battery

The first step in diagnosing why your car won’t start is to check the battery. You can do this by opening the hood and examining the battery cables and posts. Make sure they are firmly attached and free of corrosion. If they are corroded, use a solution of baking soda and water to clean them off. You should also check that the battery terminals are correctly connected to the car’s electrical system. If everything looks okay, then you can move on to troubleshooting other common issues.

Troubleshooting Common Issues

After checking the battery, it’s time to look for other common issues that could be causing your car not to start. Check all fuses and relays in your vehicle’s electrical system to make sure they are working properly. Make sure that all wires are securely connected, as loose or broken wiring can cause problems with your vehicle’s electrical system. You should also check for any signs of corrosion or other damage on any exposed wires or components in your vehicle’s electrical system.

Examining Other Electrical Components

In addition to checking fuses, relays, and wiring, you should also examine other components in your vehicle’s electrical system such as the starter motor, alternator, spark plugs, and distributor cap. Make sure these components are not cracked or damaged in any way. If you find any issues with any of these components then replace them as soon as possible so that you can get back on the road again!

Jump Starting the Battery

If all else fails then it might be time to jump start your battery. This involves connecting jumper cables from a charged battery to yours in order to temporarily provide power until you can get a new battery or recharge your current one. Be sure to follow all safety precautions when doing this!

Trying to Start the Car Manually

If jump starting doesn’t work then you may need to try starting the car manually by inserting a screwdriver into an exposed connection point between two wires near the starter motor and turning it clockwise until you hear a clicking sound indicating that power has been restored temporarily. Again be sure to follow safety precautions when doing this!

Calling a Professional for Assistance

If none of these methods work then it may be time to call a professional mechanic for assistance in diagnosing why your car won’t start and getting it back up and running again quickly and safely!
