Key fobs have become an essential part of modern car keys. They offer convenience and an added layer of security to car owners. However, what happens when your key fob stops working, and you are locked out of your car? It can be frustrating and can disrupt your day. In this article, we will outline the six reasons why a key fob will not unlock doors and how to fix them.
Reasons Why A Key Fob May Not Unlock Car Doors
Dead Battery In Key Fob
The most common reason why a key fob may not unlock a car door is a dead battery. When the battery is dead, the key fob will not transmit the signal needed to unlock the car door. To fix this, you need to replace the battery.
To replace the battery, open the key fob using a screwdriver or a small flathead screwdriver. Inside the key fob, you will see a small battery that needs to be removed and replaced with a new one. Once you have replaced the battery, test the key fob to see if it can unlock the car door.
Interference From Other Devices
Another reason why a key fob may not unlock car doors is interference from other devices. Devices like mobile phones, wireless routers, and other electronic devices can cause interference that disrupts the signal between the key fob and the car.
To fix this issue, move away from the source of interference and try again. If you are still having issues, try shielding the key fob with your hand or a piece of aluminum foil to block any interference.
Damaged Or Worn Out Key Fob
Key fobs can wear out over time, and the buttons can become damaged or worn. This can prevent the key fob from transmitting the signal needed to unlock the car door. To fix this issue, you will need to replace or repair the key fob.
Replacing a key fob can be expensive, but repairing it can be done at a fraction of the cost. You can take your key fob to a local locksmith, who can repair or replace the damaged buttons. Once the key fob is repaired, test it to see if it can unlock the car door.
Malfunctioning Receiver In Car
If your key fob is working correctly, but the car doors are not unlocking, the issue may be with the car’s receiver. The car’s receiver may not be receiving the signal from the key fob, which can prevent the car doors from unlocking.
To fix this issue, you can try resetting the receiver by disconnecting the car’s battery for a few minutes. Once you have reconnected the battery, try using the key fob to unlock the car door. If this does not work, you may need to take your car to a mechanic to diagnose and repair the issue.
Locked Out Of Car With Dead Battery
If your car battery is dead, you will not be able to use the key fob to unlock the car doors. In this situation, you can use the physical key to unlock the car door.
Most key fobs have a physical key hidden inside them that can be used to unlock the car door manually. Look for a small button on the key fob that will release the physical key. Once you have the physical key, use it to unlock the car door.
Mechanical Issues With Car Door
If none of the above fixes work, the issue may be with the car’s door lock. The car’s door lock may be stuck, preventing the key fob from unlocking the car door.
To fix this issue, you will need to diagnose and repair the mechanical issue with the car door. This can be done by taking your car to a mechanic who can diagnose and repair the issue. They may need to replace the car door lock mechanism or repair any mechanical issues that are preventing the lock from working correctly.
