Dead battery

The most common cause of a Range Rover key fob not working is a dead battery. The key fob uses a button cell battery, which has a voltage specification and a use by date. If the battery is dead or has exceeded its use by date, the key fob will not work. To fix this issue, you can replace the battery with a new one.

Worn buttons

Another possible cause of a Range Rover key fob not working is worn buttons. Over time, the buttons on the key fob can become worn or damaged, which can prevent them from making proper contact with the internal circuitry. If this is the case, you may need to replace the key fob or have it repaired.

Water damage

Water damage can also cause a Range Rover key fob to stop working. If the key fob has been exposed to water, such as from rain or accidentally dropped in water, it can damage the internal circuitry. To fix this issue, you may need to open up the key fob and clean it with electronic cleaner or replace it altogether.

Receiver module issues

The receiver module in your Range Rover can also cause issues with the key fob. If the module is not functioning properly, it may not be able to receive the signal from the key fob. This can be caused by a poor battery connection, water damage, or other issues. To fix this issue, you may need to have the receiver module replaced.

Signal interference

Signal interference can also cause problems with your Range Rover key fob. This can be caused by a variety of factors, including other radio masts, satellite systems, or even your own OBDII scanner. If this is the case, you may need to move your vehicle to a different location or try using the spare key.

In conclusion, if your Range Rover key fob is not working, there are several possible causes. These include dead battery, worn buttons, water damage, receiver module issues, and signal interference. By identifying the cause of the issue, you can take the necessary steps to fix it and get your key fob working again.

How to fix Range Rover key fob not locking or unlocking the doors

If your Range Rover key fob is not locking or unlocking the doors, there could be several reasons behind it. Here are some steps that you can follow to fix the issue.

Replacing the battery

The first thing you should check is the key fob battery. If the battery is dead or weak, it may not be able to send the signal to the receiver module in the vehicle. To replace the battery, you need to:

  1. Open the key fob using the physical key or metal retaining clips.
  2. Check the specification and use-by date of the battery to ensure it is the correct type and not expired.
  3. Replace the button cell battery with a new one of the same voltage.
  4. Reassemble the key fob and test if it is working.

Reprogramming the key fob

If the battery replacement did not solve the issue, you may need to reprogram the key fob. This can happen if the key fob is unpaired or requires reprogramming due to dead battery or defective key fob. To reprogram the key fob, you need to:

  1. Insert the key into the ignition and turn it to the “on” position without starting the engine.
  2. Press and hold the lock button on the key fob for five seconds, then release it.
  3. Turn off the ignition and remove the key.
  4. Test if the key fob is working.

Checking the ground connection

A poor ground connection can also cause the key fob not to work correctly. To check the ground connection, you need to:

  1. Locate the ground connection point in the vehicle’s wiring diagram.
  2. Use an OBDII scanner to check if there are any error codes related to the ground connection.
  3. Check the ground connection for corrosion, dust, or other debris.
  4. Clean the ground connection using electronic cleaner and isopropyl alcohol.
  5. Test if the key fob is working.

Cleaning the key fob

Water damage, wear and tear, or signal interference can cause the key fob not to work correctly. To clean the key fob, you need to:

  1. Disassemble the key fob using the physical key or metal retaining clips.
  2. Check for any water damage or corrosion on the electronic chip or rubber seals.
  3. Clean the electronic chip using isopropyl alcohol and a soft-bristled brush.
  4. Reassemble the key fob and test if it is working.

In conclusion, if your Range Rover key fob is not locking or unlocking the doors, you can try replacing the battery, reprogramming the key fob, checking the ground connection, or cleaning the key fob. If none of these steps work, you may need to take your vehicle to a certified mechanic to diagnose and fix the issue.

  1. I am an automotive locksmith and you have some wrong info printed here. You aren’t the only one. I get calls weekly someone’s FOB stops working and they think it needs to be reprogrammed. FOBS do not lose programming ever. They can break and stop working but they don’t lose programming. Usually it’s physical damage or a component on the circuit board fried providing it’s not a battery issue. When we get calls for my FOB stopped working I send those to the dealer. We specialize in lost keys. When a FOB stops working that’s a repair. The car at this point needs to be diagnosed. To make a new expensive FOB is just guessing. If I make a FOB and it’s the cars Immobilizer that’s broken it’s highly unlikely the customer is going to pay for my expensive paperweight.

    Another common misconception is people think if the battery in the FOB is dead they can’t start the car. The battery is for the buttons on the FOB. The remote part only. A transponder is what the immobilizer reads through various antennas in the car. You can remove the battery and the car should still start. Instead of using your finger on a push to start press the push to start with the FOB.
