Peugeot's 308 might be catching on a bit, but it still feels eye-catching. It's not the most luxurious car in its class, but it is an enjoyable and relaxing driving experience.
We get asked frequently at Coded Car Keys to replace peugeot key fobs. The following suggestions will aid whether the issue is persistent or intermittent.
Water Damage
If you leave your key fob in a pool or get it wet while swimming, kayaking, canoeing, rafting or canyoning, it's most likely to sustain water damage. Keep your key fob in a dry, dry bag each time you are outdoors or engage in things that expose it to excessive water.
You'll also want to make sure that the fob is completely dry prior to opening it and using it again. If you smell any odors emanating from the fob (such as industrial liquid or windshield washer fluid) It's another indication that it's submerged.
A wet circuit board can cause the battery to dump its charge, or even explode. If you can pull the 308 keyfob from the water, turn the button side up and shake as much water as you can prior to opening the casing. After you open it, take out the battery and clean the circuit board using the help of a cotton swab that has been dipped in 90 percent isopropyl alcohol.
Other reasons why your Peugeot 308 remote keyless entry system could not function include a dead coin battery, receiver module issues, signal interference, or an electronic chip malfunctioning. If none of these are the issue it is possible to reset the system by disconnecting the 12 volt battery from the car for 15 mins.
Dead Coin Battery
Peugeot cars come with a remote start system that allows the driver to start the car from a distance by warming up or cooling down the vehicle prior to entering. This feature is extremely useful particularly during the cold winter months. Remote start systems may cease to function for a variety reasons, such as an inactive coin-battery.
A coin-shaped battery that is found inside the key fob has a lifespan of two to four years, based on how often it is used and where it is purchased. The date for use-by is typically written on the package or written in the manual.
If the key fob stopped functioning after exposure to water that is clean, you should remove the battery, then clean the electronic chip using a paper towel and isopropyl ethanol, then dry it thoroughly before replacing it. In case of exposure to salty or soapy water, the chip could be fried and you will have to replace the key fob in total.
If you're unsure whether the battery is in good condition, you can check its voltage with a multimeter connected to both the minus and plus terminals. If the voltage is lower than 12-13 volts then you must replace the battery. Alternately, you could try to reset the onboard computer by disconnecting the 12 volt battery for a couple of minutes, and reconnecting it in reverse order (positive cable first followed by negative). The engine should then start after this.
Faulty Receiver Module
If you're unable to see the "Key Detected" message on your dashboard, it's possible that your receiver module has discovered a problem. It's the part that transmits an alarm to the car when your key fob is activated that also acts as an immobiliser, and stops it from starting unless the correct key is present.
This could be due to a variety of factors including water damage or simply the aging process. If your Peugeot 308 key fob has been exposed to dirty tap water, as in the electronic chip located inside is damaged. In this scenario, you'll have to remove it and clean it thoroughly using isopropyl or an electronic cleaner. When the battery is dry you can try it again.
