If your Peugeot keyfob does not work it is possible that it was exposed to soapy or clean tap water. You may have to remove the battery, clean it with isopropylethanol or electronic cleaner.
Dead coin battery
Peugeot key fobs are powered by the size of a coin. The power utilized to operate the remote locking system, as well as other functions. The battery has a short time of life and will be worn out after a long period of use. The test of voltage is a quick method to determine if the battery is damaged. A multimeter is used to measure the voltage between the battery's plus and negative poles. The results of this test will indicate whether the battery is dead or not.
If you've been using your Peugeot 3008 for a while and your key fobs have stopped working, there could be an issue with the receiver module. The receiver module is responsible for receiving radio frequency signals from the key fobs and transferring them to the vehicle's systems. If the receiver module is damaged and not functioning properly, it won't be able to send commands to other modules inside the vehicle.
Another common cause for a key fob that is not working is moisture or sweat on the circuit board. This can result in short circuits, which can draw the battery out and also disable the feature that locks the fob's remote. If this is the case, you should take your key fob to a chip level technician to fix it.

The KeyLab can be a problem when you drop your keyfob in the swimming in the pool, washed it off or left it in the rain. Water is a great conductor, and it could short out circuit boards. It can also cause corrosion to the metal lines on the key fob as well as other components. A wet circuit board can also cause the battery to drain its charge.
If you have an additional key fob, you can use it to unlock or lock the Peugeot 3008 to rule out a dead coin-cell battery as the reason for the issue. Another issue that can stop your key fob from functioning effectively is interference signals that interfere with the signal transmitted to the receiver module. These signals can be caused by a variety of sources that include radio transmitters in the area.
If you hear sloshing sound emanating from inside your Peugeot 3008 while driving, it's due to a blocked condensate drain in the evaporator.

The receiver module is not working properly.
The receiver module in the receiver module of a Peugeot 3008 is responsible for transmitting the remote keyless signal from the key fob to the receiver in the car. The receiver module could be damaged, preventing the car from recognizing your key fob. This issue can be caused by the battery being dead or water damage. Or, interference from electronic devices operating at the same frequency. In these cases, the car may show an error message saying "card not detected" on the display.
There are a variety of ways to fix this problem. You can try replacing the battery or reprogram the key fob. You could also utilize a spare key start the car. However, if the fob isn't working after all these steps, it may be a chip defective.

They can also be customized with digital printing and CNC cutouts that are machined. If your key fob has been exposed to dirty or salty tap water, the chip may be contaminated and need to be cleaned.
Faulty keyless entry systems
If you get "card not detected", this indicates that your car isn't able to receive the signal generated by your key fob. This can be caused by a variety of reasons including an insufficient or dead battery. Most of the time, the issue can be fixed by pressing the start button using the key fob. In some cases, you'll need to take the keyfob to a Peugeot dealer for further repairs.
The battery test is the first step to solving the issue with a Peugeot 3008 keyfob that won't lock or unlock doors. Batteries are the most common reason for a fob that is malfunctioning but there are other causes that can cause this issue as well. They include worn buttons, and water damage.
If your Peugeot key fob has been exposed to clean tapwater, it's a good idea for you to remove the battery. Then, dry the electronic components using paper towel. You can also use a cleaner or isopropyl ethanol for this. It's best to change the fob after it has been exposed to salt or soapy water.
