Dead Coin Battery
A dead battery in the coin compartment will prevent your Peugeot 208 from locking or unlocking, and will not start the engine. In this instance you'll need to use the alternative starting method that is described in the owner's manual.
Another reason why the 208 won't start is because the spark plugs are been worn down. The spark plugs are responsible to ignite the fuel that powers the engine. However they are limited in their life span. They'll eventually degrade in the event that they aren't utilized enough.

If the voltage falls below 11,5 volts then it's time to replace it. It is also essential to clean the contacts of the battery when it has corrosion. You can do this by lifting the rubber covers that protect the two terminals of the battery and using a wire brush to remove any parts that are corroded from the battery. You should then reconnect the cables to the positive and negative poles.

Water Damage
If your 208 won't start and the battery hasn't failed, you should check the spark plugs. It could be that they are overly dirty, causing them to not to spark. This can be fixed easily by cleaning the spark plugs in the workshop.
Peugeot cars use a key with a transponder 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, it will not send the proper signal to the vehicle.
This is a common problem that is caused by water damage. This is a common issue in colder climates where the vehicle is exposed to snow or rain. In this situation, contact an experienced locksmith who has the required tools and equipment to reprogram the key. They also have the latest technological know-how and machinery required to make a Peugeot 208 smart key. The process shouldn't take more than 15 minutes.
Faulty battery contacts
Peugeot replaced the transponder chips with a brand new model that is based on electronic components that are mounted on a circuit board. This new system works great when it's fresh, but over time the circuit boards start to degrade and stop working correctly.
This can stop the immobiliser chip from triggering and causing your car to not start. Contact
The KeyLab or a locksmith if this is the situation.
The most frequent issue is when the battery in the key fob begins to fail. This causes the blade of the key to stop feeding into your lock. A locksmith in your car can replace the battery and cut a new blade for you, it's usually a simple fix.
Faulty Receiver Module
It could be that the receiver module is faulty when your Peugeot key fob isn't working after being dropped on the floor, exposed to a sudden rainstorm or accidentally washed. The receiver module is responsible for transmitting radio frequencies to the onboard computer that controls the central locking system of your Peugeot vehicle.
The rubber seals on the key fob prevent water from reaching the electronic chip. Water can damage the chip when it is exposed to water for long periods of time. The high salt content in the ocean water or pool could cause damage to the key fob if it is submerged.
The module needs to be replaced if the Peugeot spare key does not work anymore. This is only done by a Peugeot specialist or an expert auto locksmith. Peugeot keys unlike other automobiles, are secured by an immobilizer device. This requires the correct programming to allow the car to start. This is why it is imperative that you should only trust an authorized Peugeot locksmith to create and program a replacement.
Faulty on-Board computer
The on-board computer of your Peugeot is responsible for various features in your car, including airbags and power windows. The on-board computer will show a code when something goes wrong. The code will be stored within the system until the problem is fixed. Most often, this involves replacing the computer on board.
The most common cause of the warning light for the airbag to illuminate is corrosion or loose connections in the sensor. This can be caused by wear and tear, aging, exposure to salt and moisture. It is important to have this issue addressed as quickly as possible, since an airbag that is malfunctioning can be risky in the event of an accident.
If your Peugeot is showing a card detected as not present error, the battery in the key fob may be dead or weak. This will stop the key fob sending a signal that will disable the immobilizer in your vehicle. Test this by pressing the unlock key on the key fob and then trying to start your vehicle. If this doesn't work then the battery in the key will need replacing.
