Peugeot 208 Key Replacement
It is recommended to leave the replacement of Peugeot 208 keys to auto locksmiths with the equipment and skills. They can design and program keys quicker and more efficiently than a dealership.
A dead coin battery is most likely to blame the reason why your key fob isn't locking or unlocking the doors. There are many other reasons why the key may be malfunctioning.
Dead Coin Battery
A dead coin battery will stop your Peugeot 208 from locking and unlocking, as well as making it impossible to start the engine. If this is the case, you'll have to use the backup starting method that is detailed in the owner's manual of your vehicle.
Another reason the 208 won't start is because the spark plugs have worn down. The spark plugs ignite fuel to start the engine. However, they have a limited time of life. They'll eventually break down if they aren't used frequently enough.
There is a simple solution to this issue. Verify the voltage of your battery with a multimeter. If the voltage is below 11,5 volts, then it's time to replace it. It is also necessary to clean the battery's contacts if it has corrosion. This can be done by removing the rubber covers from the two terminals of the battery, and then using a wirebrush to remove any corroded battery parts. Then, you should connect the cables to the positive and negative poles.
Water Damage
If your 208 isn't starting and the battery isn't flat, then you need to make sure that the spark plugs are working. It is possible that they're overly dirty, which causes them not to spark. This can be easily corrected by cleaning the spark plugs in the workshop.
Peugeot cars use a key with a transponder that is compatible with the immobiliser. This ensures that only the right key can turn the engine. If the chip inside the Peugeot key is damaged, it won't send the proper signal to the vehicle.
www.g28carkeys.co.uk is a typical reason for this issue. This is most common in colder climates, where the vehicle might have been exposed to rain or snow. If this is the case, seek out a reputable auto locksmith who has all the tools and equipment required to reprogram the new key. They'll also have the latest technology and equipment needed to make the Peugeot smart key. The process shouldn't be more than 15 minutes.
Contacts with the battery may be damaged.
Peugeot changed from the carbon-encased transponder chips to a brand new type of chip that uses electronic components in circuit boards. This new system works well when it's brand new, however, over time, the circuit boards start to deteriorate and stop working properly.
This can prevent the immobiliser chip activating which means that your car won't start. If this is the case it's recommended to seek out a Peugeot specialist or locksmith.
Another common issue is when the battery for the key fob begins to fail, which causes the blade of the key to stop feeding into the lock. A locksmith for cars can replace the battery and cut a new blade for you, this is normally a quick fix.
Faulty Receiver Module
It could be that the receiver module is malfunctioning when your Peugeot key fob isn't working after being dropped on the floor, exposed to a sudden rainstorm or accidentally washed. 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 key fob itself is fitted with rubber seals which prevent water from getting to the electronic chip inside. Water can damage the chip when it is exposed to the water for an extended period of time. Submerging the key fob into ocean water on the beach or throwing it into the water can be especially damaging because of the high salt content.
The module needs to be replaced if your Peugeot spare key is no longer working. This is only done by a skilled auto locksmith or Peugeot specialist. Peugeot keys unlike other automobiles, are protected by an immobilizer system. This requires the proper programming to allow the car to start. This is why you should be able to trust a professional Peugeot locksmith to handle the task of creating and programming the replacement.
Computers with faulty on-board computers
The computer on the board of your Peugeot is responsible for many of the systems inside your car, from power windows to the airbags. When something goes wrong with these systems, it will typically show a code that identifies the problem. This code is stored in the system and will stay there until the problem has been resolved. Usually, this will mean the on-board computer being replaced.
One of the main causes of the airbag light turning on is the loose or corroded connectors in the airbag sensor. This could be due to wear and tear, aging, exposure to salt and moisture. This problem should be dealt with as soon as you can, since an airbag that's malfunctioning could be dangerous in case of an accident.
If your Peugeot is showing a card not detected error then the key battery in the key fob could be dead or weak. This will stop the key fob from sending a signal to deactivate the vehicle's immobilizer. You can test this by pressing the unlock button on the key fob, then attempting to start your vehicle. If it doesn't work, the key battery is in need of replacement.
