Peugeot 308 Key Fob Problems and How to Fix Them
If your Peugeot 308 key fob has stopped working for a while it could be due to a dead battery in the coin, water damage or receiver module issues, or a damaged electronic chip. https://www.thekeylab.co.uk/peugeot-car-keys/ are all easy fixes and you can bring your car back to speed in a matter of minutes!
The key blade could become worn-out and cause an issue with your car key. It is easy to solve this issue by visiting your local Car Key Man Auto Locksmith to replace the blade.
Battery
The key fob in your Peugeot 308 may die or become weak enough to not send a clear signal. This can cause the key fob's function to cease and prevent you from opening and locking the doors, or even starting your engine. To fix this, you'll need to replace the battery in the key fob.
You can purchase a new battery at an auto parts store or at your local hardware store. When you purchase the battery, make sure that it's brand fresh and hasn't just been sitting on the shelf for too long. A brand new battery is more 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 won't unlock, it's likely that the receiver module inside the car is the culprit. The local Peugeot dealer can reprogramme the receiver module.

The internal chip of the key fob may also be damaged. You could harm your key fob if you drop it on the ground, or expose it to water. Rubber seals that protect your chip from moisture may be worn out over time. This is particularly true when you expose your key fob to water for prolonged periods of time, such as submerging it in the ocean. To avoid this you must keep your key fob away of the reach of moisture and away from water.
Water Damage
If your key fob gets submerged, whether you dropped it in the pool or fumbled it into a puddle, don't think it's a case of lost cause. Although the key fob is equipped with rubber seals which should shield it from water, prolonged exposure to water could cause damage to its electronic chip. Because water is an excellent conductor so any water that makes it inside the key fob may cause a chain of short circuits, which could eventually ruin the chip. After removing the battery scrub its contacts with isopropyl ethanol and dry it off completely before putting it back into.
A dead battery could be the reason why your Peugeot 308 won't start. If you have an extra car, jumper cables could be used to get the engine running again. If the battery is causing the problem and it is not working, it should be replaced.
A malfunctioning receiver in the car could also block it from receiving the signal from the keyfob. The key fob could be damaged or there might be a problem with the antenna, wiring or key fob itself. It might be necessary to program a new fob into your vehicle if using one. If you are unable to fix the problem yourself, contact an expert technician. A skilled technician will be able to determine the issue quickly and fix it promptly.
Radio Interference
Interference may cause symptoms such as a fob that's not being recognized or has a restricted range. The interference could be transmitted or radiated, the latter caused by speaker and power cables passing too close to electrical parts. In general, rerouting cables or moving them away from these components can solve the issue.
It's unlikely that someone is monitoring your key fob's signals to steal your car, however it is possible that the signal has been muffled by radio frequency interference. Luckily, this is a simple issue to fix.
If your key fob isn't being recognized by the system, you can try a new battery. Make sure the battery is the right size and type. Batteries of the wrong size could damage your battery.
Certain alarm systems and radar detectors use the same radio frequency as your key fob and this could cause them to interfere with your key signals. Do not connect these devices to your key fob.
Pairing Issues
The remote keyless entry system contains an antenna that receives radio frequency signals from the key fob. You won't be able to start your vehicle if the receiver is malfunctioning even if your key fob is functioning and is reprogrammable. The issue could be caused by a number of factors, including an inoperative coin battery or water damage. The receiver may also be malfunctioning due to a software error or internal damage to the key.
One of the most frequent reasons your Peugeot 308 key fob doesn't work is because the battery inside has died. This battery can be replaced, but you must be sure it's the appropriate battery for the key fob. It is best to use a battery that is the same size, voltage, and specification as the original.
Another reason the reason why your Peugeot 308 key fob might not be working is due to the fact that it is paired with a different car. You might have accidentally given the key fob to someone else or it was used to unlock other vehicles. This can be solved by reprogramming the key fob with an OBDII scan. The scanner will usually ask you for certain information regarding your vehicle, such as the VIN or engine type, and it's crucial that you enter this information correctly.
