Dead Coin Battery
A dead coin battery will stop your Peugeot 208 from locking or unlocking and will not allow you to start the engine. If this is the situation, you'll need use the backup starting method that is described in the owner's manual of your vehicle.
The spark plugs may also be worn out. The spark plugs are responsible for sparking the fuel that starts the engine. They have a limited life span. They will eventually break down if they aren't used frequently enough.
There is a straightforward solution to this issue. Check the voltage of the battery with a multimeter. If it's less than 11.5 Volts 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. You can do this by lifting the rubber covers covering the two battery terminals and using a wire brush to remove any corroded parts of the battery. Then, you should connect your cables to connect the positive and negative poles.
Water Damage

Peugeot cars have transponder keys that integrates with the car's immobiliser system. This ensures that only a valid key can turn the engine. If the chip in the Peugeot key is damaged then it will not transmit the proper signal to the vehicle.

They will also have the latest technology and equipment needed to make the Peugeot 208 smart key. The process should not take more than 15 minutes.

Peugeot replaced the old transponder chips by introducing a new type that uses electronic components that are mounted on a circuitboard. The new system is effective when it's new, but over time the circuit boards begin to degrade and stop working correctly.
This can stop the immobiliser chip from triggering which means that your car won't start. Contact a Peugeot specialist, or a locksmith, if this is the situation.

If your Peugeot key fob stopped working after dropping it on the floor, or being exposed to a sudden rain or accidently washing it the wrong way, it could be due a malfunctioning receiver module. The receiver is responsible for transmitting radio frequency signals to the onboard computer which controls the centralized locking system within your Peugeot vehicle.
The key fob itself has rubber seals that block water from reaching the chip inside. Water can damage the chip if it is exposed to water for long periods of time. Submerging the key fob into the ocean at the beach or throwing it into the pool could be particularly damaging due to the high salt content.
The module needs to be replaced if the Peugeot spare key is no longer working. This is only done by a skilled auto locksmith or Peugeot specialist. Peugeot keys, unlike other cars, are secured by an immobilizer system. This requires the proper code to begin the car. This is why it is imperative that you should only trust an authorized Peugeot locksmith to design and program the replacement.
Faulty On-Board Computer
The on-board computer of your Peugeot is responsible for many of the systems inside your car, including airbags and power windows. The on-board computer will show an error code when something goes wrong. This code will be stored within the system until the problem is resolved. Often, this will involve replacing the on-board computer.
One of the most frequent reasons for the airbag light flashing is loose or corroded connectors in the airbag sensor. This can be caused by wear and tear, aging, exposure to salt and moisture. This issue needs to be dealt with as soon as you can, as an airbag that is malfunctioning could be dangerous in case in the event of an accident.
If your Peugeot is showing a card detected as not present error, then the battery inside the key fob could be dead or weak. This could prevent the key fob from transmitting a signal that will disable your vehicle's standard immobilizer. Try this by pressing the unlock key on the fob's key and then trying to start your car. If this does not work the battery on the key has to be replaced.
