What to Do When Your Car Key Stops Working

Your car key worked fine yesterday. Today, it won't unlock the doors or start your car.

A bad car key can leave you stuck in a parking lot or your driveway. But the fix may be simple, and you might not need a new key. Try a few quick checks first. If the problem sticks around, an auto locksmith in Fayetteville, NC, can repair, replace, or program your car key.

1. Check the Key Fob Battery

A weak battery is one of the most common reasons a key stops working. You might notice the remote only works when you stand close to your car.

Try putting a new battery in your key fob. Check your owner's manual or the old battery to find the right type.

Be gentle when you open the fob. Some key cases crack if you force them apart.

2. Try Your Spare Key

Got a spare key? Give it a try. This shows you whether the problem is the key or the car.

If the spare works, your main key may have a weak battery or a broken part. If neither key works, your car may have a battery or electrical problem.

3. Look for Damage

Car keys take a lot of wear. They get dropped, soaked, and squeezed all the time.

Look for cracks, loose buttons, or other damage. If your key got wet, don't keep pressing the buttons. Water can ruin the tiny parts inside.

A damaged key may need a repair or a replacement. A locksmith can tell you if it can be fixed.

4. Move Closer to Your Car

Sometimes a key fob only works when you're close to the car. That can happen when the battery is weak or something blocks the signal.

Stand near the driver's door and press the unlock button. If it works up close but not from far away, check the battery first.

What if it only fails in one spot? Nearby electronics might be messing with the signal. Move your car to a new spot and try again.

5. Use the Hidden Key Inside Your Fob

Many key fobs have a small metal key inside. You can use it to unlock the driver's door when the remote won't work.

Look for a small button or switch on the fob. Slide it or press it to pull out the hidden key.

Some cars hide the keyhole under a little cover on the door handle. Check your owner's manual to find it and open it.

6. Check Your Car's Battery

Sometimes the key is fine. A weak car battery can stop your car from answering the key fob.

Watch for signs like dim dashboard lights or a car that won't start. If your spare key fails too, the car battery may need help.

Does your car have a push-button start? Look in your owner's manual for the backup way to start it. In many cars, you can hold the fob right next to the start button.

7. See If the Key Needs Programming

Some car keys have a tiny chip inside. The chip helps your car know it's the right key. If the car doesn't recognize it, the engine may not start.

This can happen after a battery problem or other electrical trouble. It can also happen if a new key wasn't programmed the right way.

Don't try random programming steps you find online. The right steps depend on your car's make, model, and year.

When Should You Call a Locksmith?

If your key still won't work after these checks, it's time to get help. A locksmith can check the key and find the cause.

You may need help if:

• Your key fob has stopped working completely.

• The key turns, but the car won't start.

• Your car doesn't recognize the key.

• You lost your only car key.

• Your key is broken or stuck in the lock.

A locksmith might repair your key, make a new one, or program a new one. The best fix depends on your key and your car.
