https://www.thekeylab.co.uk/peugeot-car-keys/ is the most likely cause if your key fob stops locking or unlocking doors. There are other possibilities that the key is malfunctioning.
Dead Coin Battery
A dead coin battery will stop your Peugeot 208 from locking and unlocking, and also stopping it from starting the engine. If this is the case, you'll need to apply the backup starting technique which is explained in the owner's manual for your vehicle.
The spark plugs can also be worn out. The spark plugs are responsible for instigating the fuel that ignites the engine. However they are limited in their lifespan. If they are not used enough to last, they'll eventually fail.
There is a simple solution to this problem. The best option is to test the voltage of your car battery with a multimeter. If it's less than 11.5 Volts and you are not satisfied, then it is time to replace it. It is also important to clean the contacts of the battery in the event that it is damaged by corrosion. This can be done by removing the rubber covers off the two terminals of the battery, and then using a wirebrush to remove any corroded parts of the battery. Then, reconnect the positive pole cables to the negative.
Water Damage
If your 208 does not start and the battery has not fallen flat, it is time to look at the spark plugs. It is possible that they're overly dirty, which causes them not to spark. The spark plugs can be cleaned in a workshop.
Peugeot cars use a key with a transponder that is compatible with the immobiliser. This ensures only the correct key is able to turn the engine. If the chip inside the Peugeot key is damaged, then it won't transmit the correct signal to the vehicle.
Water damage is a common reason for this issue. This is a typical issue in warmer climates where the vehicle is exposed to rain or snow. In this instance, you should contact a reputable locksmith who will have the required tools and equipment to reprogram the key. They will also have the latest technology and equipment needed to make the Peugeot 208 smart key. The process shouldn't take more than 15 minutes.
Faulty Battery Contacts
Peugeot replaced the old transponder chips by introducing a new model that is based on electronic components that are mounted on a circuitboard. This new system works well when it's fresh, but over time the circuit boards start to deteriorate and stop working correctly.
This could stop the immobiliser chip activating, so your car won't start. Contact a Peugeot specialist, or a locksmith, if this is the situation.

Another common issue is when the battery for the key fob begins to fail, which causes the key blade to stop feeding into the lock. A locksmith for cars will replace the battery, and then cut a new blade for you. This is a simple solution.
Faulty Receiver Module
It could be that the receiver module is faulty If your Peugeot key fob isn't working after being dropped on the floor, or exposed to a sudden downpour or accidentally washed. The receiver module is responsible for transmitting radio frequencies to the onboard computer which manages the central locking system of your Peugeot vehicle.
The rubber seals on the key fob keep water from reaching its electronic chip. However prolonged exposure to water could break through these seals, causing damage to the chip. The high salt content in the pool or ocean water can cause damage to the key fob, especially if it is submerged.
If your Peugeot spare key fob doesn't work it is necessary to have the module replaced. This is only done by an expert auto locksmith or Peugeot specialist. Peugeot keys like other cars are secured by an immobilizer device. This requires the right code to begin the car. This is why you must trust an experienced Peugeot locksmith with the task of designing and programming an alternative.
Faulty On-Board Computer
The on-board computer in your Peugeot is responsible for various systems inside your car, including airbags and power windows. When something goes wrong in these systems, it will usually display a code that identifies the problem. This code is stored inside the system and stays there until the issue is fixed. Usually, this will mean replacing the computer on board.
One of the most frequent causes of the airbag light turning on is loose or corroded connection in the airbag sensor. This could be due to wear and tear, aging or exposure to moisture and salt. It is important to have this issue addressed as quickly as possible, since an airbag that is not functioning properly could be risky in the event of an accident.
If your Peugeot is showing a card detected as not present error then the key battery inside the key fob may be weak or dead. This will stop the key fob from sending a signal to disarm the immobilizer in your vehicle. Test this by pressing the unlock button on the key fob and then trying to start your vehicle. If this fails the battery on the key must be replaced.
