This is basic stuff, and there is little chance it to happen. But, having a look nonetheless is not going to hurt.

In some unusual cases, your car door locks won’t open despite everything looking fine. Before jumping to any other step, look at the key fob itself. Use the spare key fob to find out whether your car key is okay. If the spare fob can open the door, then your car remotes definitely have a problem. Also, it might sound silly, but check whether you are using the wrong key.

Remote Key Fob Battery Issues

Every key fob has batteries set in them. Most cars have key fobs with lithium-ion batteries. These batteries have a long shelf-life and are not much expensive either.

Checking the remote’s battery is a good way to start the inspection. The key remote with a dead battery won’t work. Look at this first if your keys stop working.

You can follow a few ways to find the battery model for your car’s remote. First, look at the owner’s manual. Contact a nearby dealer around you if you can’t find the specific dead key fob battery model from the owner’s manual. Also, the model of the key fob batteries is printed on its body. So you can also check this by opening the remote.

Car Key Needs Reprogramming

Your vehicle has a receiver to receive the signals from the remote key. The remote key’s transmitter connects with the vehicle’s receiver to send signals from the key to the vehicle. This is an important mechanism to work the key and vehicle perfectly together.

Technology like this enhances the security system and safety of the vehicle. But it can also stop you from starting the car if the signal connection is not properly paired. If your keyless entry remote stops connecting with the vehicles, you must change the program structure or have an alternative programming sequence. By moving the ignition key a few times, you can do this. Make the door shut before doing this.

You can follow the following steps to fix and reprogram the key –

  • Get inside your car and lock the door handle.
  • Put the key in the ignition hole.
  • Turn the key repeatedly from the locked to the run position to start the car. But do this without starting the car. The frequency of turning the key will change depending on the specific vehicle model.
  • After turning the key a few times, you will possibly hear a chime. The chime should happen again when you press the lock button or the remote’s unlock button.
  • If these steps happened to you, your remote key fob would operate again.

Broken Contacts In Car Key Fob

A remote key fob does not work like a physical key, but it still faces a lot of interaction. The battery connector terminals and buttons are two of the most places to suffer the destruction effect.

Many times just by having a good look, you can find out the hard part. If the battery terminal gets broken, it will feel loose. You can also notice this by looking at this. You can try it by soldering, which might make this work again.

Sometimes the problem lies in other places than the battery terminals. Internal components like buttons also get soldered sometimes. In most cases like these, you will need a new fob.

Damaged Transmitter In The Keyless Entry Remote

The remote key has transmitters installed to establish a connection with the vehicles. Having issues in the transmitter won’t let your vehicle be connected with the key. Thus, you can’t control the vehicle.

In the same way, the vehicle also has a component to connect with the key’s transmitter. This component is named as receiver. Issues in either the transmitter or receiver will impact the connecting signals.

A damaged receiver or transmitter will need the hands of a professional locksmith. Contact an automotive locksmith to fix the receiver or transmitter.
