Battery
The key fob on your Peugeot 308 may die or become weak enough to not send a strong signal. This could cause the key fob to stop working which prevents you from locking and opening the doors or starting your engine. You'll need a replacement battery for your key fob to fix this.
https://www.thekeylab.co.uk/peugeot-car-keys/ can buy a brand new battery at an auto parts store, or at your local hardware store. Make sure that the battery is brand new and has not sat on the counter for too long. A new battery has greater capacity and will send a stronger signal to your car.
After replacing the battery try unlocking the doors and locking them with the key fob. If the doors don't open, it's likely that the receiver module in the car is at fault. The local Peugeot dealer can reprogramme the receiver module.
The internal chip of the key fob can also be damaged. This could happen when you drop your key fob on the ground or expose it to water. The rubber seals that shield the chip from moisture might wear down over time, particularly if your key fob is exposed to water for lengthy periods of time, such as submerging it in the ocean at the beach. To stop this from happening, you must keep your key fob away from water and never let it come in contact with water.
Water Damage
If your key fob gets wet in water, whether you tossed it into the pool or threw it into a puddle don't think that it's an accident. While the key fob comes with rubber seals that should protect it from water, long-term exposure to water may cause damage to the electronic chip. Water is a great conductor, and any water that is absorbed into the key fob will cause the short circuits to be in series which can eventually harm the electronic chip. After removing the battery, scrub its contacts with isopropyl ethanol and dry it completely before putting it back in.
A dead battery can also be the reason your Peugeot 308 won't start. Jumper cables can be a great way to restart the engine if you own an extra car. If the battery is faulty, it must be replaced.
A poor receiver in the car could also block it from receiving the signal from the key fob. It could be a problem with the antenna or wiring or the key fob might be damaged. If you're using a new key fob it may need to be programmed for the vehicle. If you're unable to solve the issue, contact a professional technician. A technician trained in the field will be able to determine the issue quickly and resolve it quickly.
Radio Interference
Signs like keys not being recognized or having a limited range of operation usually mean there is a problem with the system. This is either radiated or conducted, with the former resultant from power supply cables or the speaker wiring being too close to electrical components. Generally speaking, rerouting cables or moving them away from the components can resolve the issue.
It's unlikely someone is watching your key fob signal in attempt to steal your car or vehicle, but it's possible that radio interference has ruined the signal. This is a simple problem to resolve.
If you're having issues with your keys that are not recognized, try using a fresh battery. Also, make sure that the battery you are using is the proper size and type. Batteries that are not of the correct size could damage your battery.
Some aftermarket alarm systems and radar detectors use the same radio frequency as your key fob and they could cause them to interfere with your key signals. It is best to avoid using these devices with your key fob.
Pairing Issues
The remote keyless entry system that is used in automobiles has a receiver which receives radio signals from the key fob. If the receiver has developed a problem, you won't be able to start your car even if your key fob works and can be modified. The issue can be caused by a range of causes, including the dead battery in the coin and water damage. The receiver could also be malfunctioning as a result of an internal or software issue or damage to the key itself.
The battery inside your Peugeot 308 keyfob may have been drained. The battery can be replaced, but ensure that it's the correct battery for your key fob. A bad battery can result in further problems with the key fob, therefore it's best to use the original or the replacement that is identical in size, voltage, and specification.
Another reason that your Peugeot 308 key fob might not be working is due to the fact that it is linked to a different car. It is possible that you have accidentally given the key fob to a friend, or the key was used to unlock other vehicles. This can be solved by reprogramming the key fob with an OBDII scan. This tool will request details about your car such as its VIN or engine type. It is vital that you enter the correct details.
