Peugeot 3008 Key Fob Problems
The mid-sized SUV from Peugeot 3008, has a number of positive aspects. It drives well, looks great and has a large boot. Can it compete in the most competitive segment of the market perhaps?
If your Peugeot key fob isn't functioning, it may have been exposed to clean tap water or soapy water. You may have to remove the battery, clean it using isopropyl alcohol or electronic cleaner.
Dead coin battery
Peugeot key fobs include a small coin battery that powers their remote locking and other functions. This battery has a limited life span and may be worn out after a long period of use. The test of voltage is a quick way to determine if the battery is defective. Multimeters are used to measure voltage between the plus and minus poles of the battery. This test can determine whether the battery is dead.

If you've been using your Peugeot 3008 for a while, and your key fobs aren't working, there could be a problem with the receiver module. The receiver module is responsible for capturing radio frequency signals from key fobs, and then sending them to the car's systems. If the receiver module is defective or damaged, it will not be able to transmit commands to the other modules of the vehicle.
Moisture or sweat on the circuit board is another frequent reason for an inoperable key fob. It can trigger short circuits that drain the battery and stop the remote locking feature of the fob. If G28 is the case, you should take your key fob to an expert in chip level repair to repair it.
Water damage
Whether you dropped your key fob into the pool, threw it in the washer or even left it in the rain for too long, water damage can be a serious issue. Water is a great conductor and can cause a short circuit on circuit boards. It can also cause corrosion to the traces of metal and other components of the key fob. A wet circuit could cause batteries to lose their charge.
If you have an extra key fob, use it to lock or unlock your Peugeot 3008 to rule out the possibility that a dead battery is the source of the issue. Interference signals can cause your key fob to not function properly. These interfere with the signal generated by the receiver module. These signals could come from a wide range of things that include radio transmitters near by.
If you hear sloshing noises coming from your Peugeot 3008 when driving, this is likely due to a clogged condensate evaporator drain. You can test this by blowing compressed air into the drain holes under your door. You can also use a flexible metal wire for wriggling drain holes to get rid of any dirt that has built up. Air pockets can also be detected by sloshing noises.
Faulty receiver module
The receiver module in the Peugeot 3008 key fob is responsible for transferring the remote keyless system signal from the key fob to the car's receiver. If the receiver module is damaged, it will prevent the car from recognizing the key fob. This issue could be caused by the battery being dead or water damage. It could also be caused by interference from electronic devices operating at the same frequency. In these situations the car could display an error message saying "card not detected" on the display.
There are a variety of ways to resolve this issue. You could try replacing the battery or reprogramming your key fob. You could also use a spare key in order to start the car. However, if the fob isn't functioning after these steps, it could have a chip that's faulty.
It is recommended to remove the chip and clean it with paper towels and rubbing alcohol. If the chip is fried you need to purchase a new one. The FB Series enclosures come with the battery holder for coins that can be used with the most popular types of key fob batteries. They can also be customized by using digital printing and CNC machined cutouts. If your key fob was exposed to dirty or salted tap water, it's possible that the chip is contaminated.
Faulty keyless entry system
If you get the message "card not detected", it indicates that your car is unable to receive a signal from your key fob. This can be caused by several factors, including a weak or dead battery. Most often, the issue can be fixed by pressing the start button using the key fob. In some cases, however, you may need to take your key fob to an Peugeot dealer for further repairs.
The first step to troubleshooting a Peugeot 3008 key fob that's not able to unlock or lock the doors is to test the battery. Batteries are usually the cause of an issue with the key fob. However, there are also other factors that may be involved. These include worn buttons as well as water damage.
If your Peugeot key fob has been exposed to clean tapwater, it is a good idea to remove the battery. Then, dry the electronic components with paper towel. You can also make use of a cleaner or isopropyl ethanol for this. If the fob has been exposed to salt or soapy water, it's recommended to replace it.
If your key fob still doesn't work you can reset it by taking out the 12 volts battery for 15 minutes. Then, reconnect the negative cable first, then followed by the positive cable.
