Battery

The key fob battery in your Peugeot 308 can sometimes die or become too weak to send an intense signal to your car. This can cause the key fob's function to cease which prevents you from locking and opening the doors or starting your engine. To fix this issue, you'll need to replace the battery in the key fob.

You'll need to purchase batteries for replacement from an auto parts store or your local hardware store. Make sure the battery is brand new and has not stored on the counter for too long. A new battery has greater capacity and can transmit a stronger signal your car.

After replacing the battery, try unlocking the doors and locking them using the key fob. If the doors won't open, the problem is likely to be in the receiver module of the car which can be programmed by your local Peugeot dealer.

The chip inside the key fob might be damaged. You can cause damage to your key fob if you drop it on the ground, or expose it to moisture. The rubber seals that protect the chip from moisture could wear down over time, especially if your key ring is exposed to water for extended durations, like submerging it in the ocean at the beach. To prevent this from happening you should keep your key fob free of water and out of water.

Water Damage

If your key fob is wet regardless of regardless of whether you dropped it in the pool or threw it into a puddle don't think it's a loss. The key fob is protected by rubber seals, however, prolonged exposure to water may harm its electronic chip. Because water is a good conductor so any water that is able to get inside the key fob could create a series of short circuits, which could eventually ruin the chip. After removing the batteries clean the contact surfaces with isopropyl and then dry them completely before putting them back into.

Your Peugeot 308 may not start due to the battery being dead. Jumper cables can be a great method to start the engine when you have an additional car. If the battery is the issue and it is not working, it should be replaced.

Another reason could be an ineffective receiver in the vehicle, which may hinder it from receiving a signal from the key fob. It could be a problem with the antenna or wiring or the key fob might be damaged. It might be necessary to program a new fob into your vehicle if using one. If you cannot fix the issue on your own seek out an expert technician. A technician trained in the field will be able to diagnose the problem quickly, and then fix it right away.

Radio Interference

For example, a key fob not being recognized or having a narrow range usually indicate that there is an interference in the system. This is either radiated or conducted, with the former being caused by power supply cables and speakers wiring that are too close to electrical components. In general, rerouting cables and moving them away from these components can solve the problem.

It's unlikely that someone is monitoring the signals from your key fob to steal your car, but it's possible that the signal is being distorted by radio frequency interference. This is an easy issue to fix.

If you're experiencing a problem with your key fob not being recognized, try an entirely new battery. Also, ensure that the battery you are using is the proper size and type. If the battery is not properly sized, it could damage the fob.

These devices may interfere with the key signal if they operate on the same radio frequency. Beware of attaching these devices to your key fob.

Pairing Issues

A car's remote keyless entry system is an antenna that receives radio frequency signals from the key fob. If the receiver is experiencing an issue, you will not be able to start your car, even if the key fob functions and is reprogrammed. The issue could be caused by a number of things, including a dead coin battery and water damage. The receiver may also be malfunctioning due to a software error or internal damage to the key.

One of the main reasons that your Peugeot 308 key fob isn't working is that the coin battery inside has gone out of service. The battery can be easily replaced, but you need to make sure that it is the appropriate battery for the keyfob. A bad battery can lead to further problems with the key fob, so it is recommended to use the original battery or an equivalent replacement in size, voltage and specification.

Your Peugeot 308 keyfob may not function if it was linked to another vehicle. You may have accidentally given your key fob a friend or the key was used to unlock other vehicles. This can be resolved by reprogramming your key fob with an OBDII scanner. This scanner will typically ask you to provide certain details about your vehicle, like the VIN or engine type, so it's essential to enter it correctly.
