Peugeot 308 Key Fob Problems and How to Fix Them

If your Peugeot key fob suddenly stopped functioning it could be due to an unresponsive battery in the coin-cell or water damage, receiver modules problems, or a damaged chip. Fortunately, these issues are easy to fix and you'll be able to get your car back to normal in no time at all!

The key blade may become worn out and lead to an unusable car key. This can be fixed to fix the problem if you go to your local Car Key Man Auto Locksmith and let them fit an entirely new key blade for you.

Battery

The key fob inside your Peugeot 308 may die or become weak enough to not send a strong signal. The key fob might be inoperable and prevent you from locking or unlocking your doors, or even starting your engine. You'll need a replacement battery for your key fob to correct this.

You'll need the replacement battery from an auto parts store or a local hardware store. When you purchase the battery, ensure that it's fresh and hasn't just been sitting on the shelf for a long time. A brand new battery is more capacity and will transmit a stronger signal to your vehicle.

After replacing the battery, try unlocking the doors and locking them with the key fob. If the doors don't unlock the issue is likely in the car's receiver module which can be changed by your local Peugeot dealer.

The chip inside the key fob can also be damaged. It's possible to cause damage to your key fob when you drop it on the ground, or expose it to moisture. The rubber seals that shield the chip from moisture might become worn down over time especially if your key ring is exposed to water for long period of time, like when you submerge it in the ocean at the beach. To stop this from happening, it's important to keep your key fob away from moisture and to never let it come in contact with water.

Water Damage

If your key fob gets wet, whether you dropped it into the pool or threw it into a puddle, don't assume it's a loss. Although the key fob is equipped with rubber seals that should protect it from water, long-term exposure to water may result in damage to its electronic chip. Water is a great conductor and any water that comes into the key fob will trigger the short circuits to be in series which eventually damage the electronic chip. After removing the battery, scrub its contacts with isopropyl alcohol and dry it completely before putting it back into.

A dead battery might be the reason that your Peugeot 308 won't start. Jumper cables can be a great way to restart the engine if you own an additional vehicle. If the battery is faulty it is required to replace it.

Another reason could be a malfunctioning receiver in the vehicle, which may block the signal from the key fob. The key fob may be damaged or there might be an issue with the antenna, wiring, or the key fob itself. https://www.thekeylab.co.uk/peugeot-car-keys/ could be necessary to programme a new key fob to your vehicle if you are using one. If you're not able to solve the issue, call a professional technician. A technician who is trained in the field will be able to detect the issue quickly and then fix it right away.

Radio Interference

Interference can result in problems such as a key fob that isn't recognized or has a limited range. The interference can be radiated or transmitted, the latter caused by power and speaker cables that are too close to electrical components. Generally, re-routing the cables or moving them away from the components can solve the problem.

It's unlikely that someone is monitoring your key fob signals to take your car away, but it is possible that the signal has been drowned out by radio frequency interference. Luckily, this is a simple issue to repair.

If your key fob is not being recognized by the system, you can try a new battery. Make sure that the battery is the right size and type. Batteries of the wrong dimensions can harm your battery.

Certain alarm systems and radar detectors operate on the same radio frequency as your key fob, and could cause them to interfere with your key signals. It is best to avoid using these devices on your key fob.

Pairing Issues

A car's remote keyless entry system has a receiver that receives radio frequency signals from the key fob. If the receiver is experiencing problems, you won't be capable of starting your car regardless of whether the key fob is functional and is modified. The issue could be caused by a range of reasons, such as the battery of a coin that is dead and water damage. The receiver may also be malfunctioning due an error in the software or internal damage to the key itself.

One of the most common reasons your Peugeot 308 key fob is not working is because the coin battery inside has died. The battery can be replaced, but be sure it's the proper battery for your keyfob. A bad battery can cause more problems with the key fob, so it's best to use the original or the replacement that is identical in size, voltage and specification.

Your Peugeot 308 keyfob may not work if it is linked to an unrelated vehicle. This can happen if you have given your key fob to a person you know or if the key has been used to unlock and start other vehicles. This issue can be solved by reprogramming your key fob with an OBDII scan. This tool will ask for details about your car, for example, its VIN or engine type. It is essential that you enter the correct information.
