A dead battery for your coin is most likely to blame the reason your key-fob stops locking or unlocking the doors. There are also other reasons that the key might be malfunctioning.
Dead Coin Battery
A dead coin battery will stop your Peugeot 208 from locking and unlocking, as well as hindering it from starting the engine. If this is the case, you'll have to apply the backup starting technique which is explained in the owner's manual of your vehicle.
Another reason your 208 might not be starting is because the spark plugs have worn down. The spark plugs are responsible to ignite the fuel that ignites the engine. However, they have a limited lifespan. If they are not used enough, they will eventually fail.
Luckily, there is an easy solution for this problem. The best way to solve this issue is to test the voltage of your car battery using a multimeter. If the voltage falls below 11,5 volts, it's the time to replace it. It is also important to clean the battery's contacts in case it is corroded. This can be done by removing the rubber cover from the two terminals on the battery and then using a wirebrush to clean any parts of the battery that are corroded. Then, reconnect your cables to connect the positive and negative poles.
Water Damage
If your 208 doesn't start and the battery has not gone flat, you should examine the spark plugs. You might find that they're filthy and don't spark. The spark plugs can be cleaned in a workshop.
Peugeot cars use a transponder style key that works with the car's ignition system. This ensures that only a valid key can turn the engine. If the chip inside the Peugeot key is damaged then it will not transmit the correct signal to the vehicle.
This is a very common issue that is caused by water damage. This is particularly prevalent in colder climates, where the vehicle could have been exposed to snow or rain. If this is the case, seek out a reputable auto locksmith who has all the tools and equipment needed to change the key's programming. They also have the latest technology and equipment needed to create a Peugeot 208 smart key. The process should take no more than 15 minutes.
Contacts to the battery are not working properly.
Peugeot replaced the old transponder chips with a new model that is based on electronic components mounted on a circuit board. This new system works great when it's new, but as time passes, the circuit boards start to deteriorate and stop working properly.
This can prevent the immobiliser from working, so your vehicle won't be able to start. Contact an Peugeot specialist or a locksmith, if this is the case.
Another common issue is when the battery of the key fob starts to die, this causes the key blade to stop from entering the lock. A locksmith in your car can replace the battery and cut a fresh blade for you, it's usually a simple fix.
Faulty Receiver Module
If your Peugeot key fob has stopped working after dropping it on the floor, getting exposed to a sudden downpour or accidently washing it, it could be due to a malfunctioning receiver module. The receiver module is responsible for transmitting radio signals to the onboard computer that regulates the central locking system of your Peugeot vehicle.
The key fob itself has rubber seals that prevent water from getting to the electronic chip inside. However, prolonged exposure to water could cause damage to these seals and the chip. The high salt content of the ocean water or pool can cause damage to the key fob when it is submerged.
If your Peugeot spare key fob doesn't work it is necessary to have the module replaced. This can only be completed by an experienced auto locksmith or Peugeot specialist. Peugeot keys unlike other automobiles, are secured by an immobilizer device. This requires the correct codes to start the car. This is the reason why you should only be able to trust a professional Peugeot locksmith for the job of creating and programming an appropriate replacement.
peugeot 3008 key fob On-Board Computer
The on-board computer in your Peugeot is responsible for many of the systems in your car, ranging from power windows to the airbags. If something goes wrong with these systems, it'll typically show a code that identifies the problem. This code is stored inside the system and remains there until the issue is fixed. This may require the on-board computers to be replaced.
One of the main causes of the light coming on is loose or corroded connection in the airbag sensor. This could be due to wear and tear, aging, exposure to salt and moisture. This issue should be dealt with as soon as you can, since an airbag that is not functioning could pose a risk in the event of an accident.
If your Peugeot is showing a card not detected error, the battery in the key fob might be weak or dead. This will 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 it doesn't work the battery on the key needs to be replaced.
