Why Does My Car Say No Key Detected?

If your car tells you that there’s no key detected, it’s probably because you haven’t started the engine yet.

Once the engine is running, the car will recognize any key that’s in the ignition and start working with it.

Check the ignition

If your car is saying “no key detected” and you don’t have a key, there are a few things to check.

Make sure that your ignition is actually turned off. If it’s not, then your car may be thinking that your key is in the ignition when it isn’t.

Check the interior of your car as well. If you have an electronic key fob or some other kind of keyless entry system, make sure that it’s nearby and working correctly.

If you do use a fob or other device for entering or starting your car, try using it to see if that helps get rid of the “no key detected” message.

Check the dashboard

Check the dashboard. If your car has a keyless entry system, make sure your key fob is in the range of the car.

You may need to reprogram your key fob or replace it.

You can also check to make sure that the battery isn’t dead by plugging in the charger for at least 15 minutes and then trying again.

Check your car doors

When your car says no key detected, it’s usually because the doors aren’t closed all the way.

Check to make sure that the doors are all locked and try again. If this doesn’t work, try turning the ignition off and back on again.

If that doesn’t work, you may need to check your fuses or contact a mechanic.

Why does it say that?

The key fob is what lets the car know to unlock itself when you get close to it.

So if the battery dies, or even if it just runs out of juice from being left in a hot place for too long, then your car won’t recognize that you have a key on you as you approach.

What the causes no key detected?

The most common cause for a car to say no key detected is that the battery in your car has failed.

If your battery is dead, then the security system will not be able to recognize when you insert the key into the ignition and turn it.

The car will know there’s something in there, but it won’t be able to tell if it’s actually a key or just a piece of metal.

It’s also possible that your ignition switch has failed, which means you’ll need to have your car towed to a mechanic for repair.

What are the possible solutions?

Check that the battery hasn’t been drained. If it’s dead, plug in the charger and wait for the battery to charge up.

Turning off the engine and then turning it back on again. This will reset the computer system and may solve the problem.

If neither of these solutions works, it could be something else entirely but there’s no harm in trying!


If you’re sure you have your keys and they’re in the ignition, but your car still says no key detected, then it’s likely that there is a problem with the electronic lock on your vehicle.
