Dead coin battery
Peugeot key fobs are powered by the coin-sized battery. The power used to control the remote locking mechanism and other features. This battery has a finite lifespan and can wear out over the course of years of usage. A simple way to check whether the battery is defective is to conduct the voltage test. Multimeters are used to determine the voltage between the plus and minus poles of the battery. The results of this test will indicate whether the battery is dead or not.
The receiver module could be the reason why the key fobs that you have not been able to use after using your Peugeot 3008 for a prolonged period. The receiver module is responsible for receiving radio frequency signals generated by the key fobs, and sending them to the car's systems. If the receiver module is damaged, it will not be able send commands to the other modules inside the vehicle.
Moisture or sweat that gets on the circuit board is another frequent cause of an unworking key fob. This can cause short circuits that cause the battery to be depleted and disable the feature that locks the fob's remote. If this happens you need to bring your key fob in to a technician that specializes in chip level repairs.
Water damage
Water damage can be a concern in the event that you dropped your keyfob in the swimming pool, washed it or left it outside in the rain. Water is a good conductor, and it could cut off circuit boards. It can also cause corrosion to metal traces on the key fob and other components. A wet circuit can cause the battery to lose its charge.
If you have a spare key fob, use it to lock or unlock your Peugeot 3008 to rule out the possibility that a dead coin battery is at the root of the problem. Another issue that can prevent your key fob from functioning effectively is interference signals that interfere with the signal sent to the receiver module. These signals could come from a variety of things that include radio transmitters near by.
If you hear sloshing sound coming from inside your Peugeot 3008 while driving, it's due to a blocked condensate drain of the evaporator. You can check for this by locating the drain holes underneath your door and blowing compressed air through the drain holes. You can also use a flexible wire to play with the drain holes and dislodge any dirt that may have been accumulating there. Sloshing noises can be an indication that there are air pockets in the coolant system.
Faulty receiver module
The receiver module on the Peugeot 3008 key fob is responsible for transmitting the remote keyless system signal from the key fob to the car's receiver. If the receiver module is damaged, it could hinder the car's ability to recognize the key fob. Other reasons that could cause the issue include the battery being dead or water damage, as well as interference with electronic devices that operate at the same frequency as the key fob. In these situations the car might display the message "card not detected" on the display.
There are a variety of ways to troubleshoot this issue. You might try replacing the battery or reprogramming the key fob. You can also use a spare key to start the car. However, if the key fob doesn't work after all these steps, it might have a chip that is defective.
It is best to remove the chip and clean it using rubbing alcohol and paper towel. If the chip is damaged, you must purchase a new one. The FB Series enclosures come with an holder for coin cells that is compatible with the most common types of key fob batteries. These enclosures can be customized by using digital printing or CNC-machined cutouts. If your key fob was exposed to salty or dirty tap water, the chip may be contaminated and need to be cleaned.
Faulty keyless entry systems
If you get "card not detected", this means that your car cannot receive an alert from your key fob. This could be due to a variety of causes, including batteries that are weak or dead. In most cases, the issue will be fixed by pressing the start button using the key fob. In G28CarKeys , you'll have to take the keyfob to a Peugeot dealer for further repairs.

Examining the battery is the first step to troubleshooting an Peugeot 3008 keyfob that won't unlock or lock doors. Batteries are the most frequent cause of a malfunctioning fob but there are other factors that could contribute to this issue too. These include worn buttons, damage to the receiver module, water issues, and signal interference.
If you've recently been exposed to water and have your Peugeot key fob exposed to pure tap water it's a good idea to remove the battery and dry the electronic components with paper towel. You can also use isopropyl Alcohol or cleaning solution to do this. It is best to change the fob when it has been exposed to salt water or soapy water.
