Faulty Receiver Module
If your Peugeot key fob was not working after dropping it on the floor, getting exposed to a sudden rain or accidently washing it the wrong way, it could be due to a defective receiver module. The receiver is responsible for sending radio frequency signals to the on-board computer which controls the centralized locking system in your Peugeot vehicle.
The rubber seals on the key fob block water from getting to the electronic chip. However, prolonged exposure to water may cause damage to these seals and the chip. The high salt content of the pool or ocean waters could cause damage to the key fob when it is submerged.

Faulty on-Board computer
The computer on board of your Peugeot is responsible for many of the features in your car, including power windows and airbags. The computer on board will display an error code when something goes wrong. This code is saved in the system and stays there until the issue is solved. Usually, this will mean replacing the computer on board.
One of the most frequent reasons for the light coming on is loose or corroded connections within the airbag sensor. This can be caused by wear and tear, aging, exposure to salt and moisture. This issue must be addressed as soon as you can, as an airbag that is not functioning could pose danger in the event of an accident.
If your Peugeot is showing a card not detected error, then the battery inside the key fob may be weak or dead. This will stop the key fob from sending a signal to deactivate your vehicle's immobilizer. Try this by pressing the unlock button on the fob's key and then trying to start your vehicle. If this fails then the battery in the key fob is in need of replacement.
