Here at Coded Car Keys we are often asked to replace peugeot 308 key fobs. Whether the problem is constant or intermittent the following tips will help.
Water Damage
If you accidentally drop your key fob in a puddle or splash it with water while kayaking, swimming canoeing, rafting, or canyoning, it's more likely to be damaged by water. Keep your key fob in a dry bag whenever you go outside or engage in things that expose it to excessive water.
It's also essential to make sure the fob has completely dried out before you open it to use it again. If you smell any odors from the fob (such as industrial fluid or windshield washer fluid) it is a indicator that it is submerged.
A circuit board that's wet can cause the battery to dump its charge, or even explode. If you're able to fish your 308 key fob out of the water body it was stuck in then flip the button side down and shake it out as much water as you can before opening the case. Once you have opened it, take out the battery and clean the circuit board with a cotton swab dipped in 90-percent isopropyl alcohol.
Other reasons your Peugeot 308 remote keyless entry system could not function include the battery of your coin is dead, receiver module issues signal interference, an electronic chip malfunctioning. If none of the above are the cause you can reset the system by disconnecting a 12 Volt battery from the vehicle for 15 minutes.
Dead Coin Battery
Peugeot cars are equipped with remote start systems that allows drivers to start their vehicle from an extended distance, which allows them to warm up or cool down the vehicle before entering. This feature is extremely useful particularly during the cold winter months. Remote start systems can not function due to a variety of reasons, such as an inactive coin-battery.
A coin-shaped battery that is in the key fob has a lifespan of two to four years, based on how often it's used and where it is purchased. The date for use-by will be written on the packaging or mentioned in the user manual.
If the key fob stopped functioning after exposure to clean tap water it is recommended to take the battery off, clean the electronic chip with a paper towel and isopropyl Alcohol, then dry it thoroughly before replacing it. If the key fob was exposed to soapy or salty water, it could have fried the chip. You'll need to replace it.
If you're not certain that the battery is not working properly, you can test its voltage using a multimeter that is set to the car's voltage range. Connect it to the terminals for minus and plus. The voltage should be between 12-13 volts but if it's lower, the battery must be replaced. Alternatively, you can try to reset your on-board computer by disconnecting the 12 volt battery for a few minutes, and then reconnecting it in reverse order (positive cable first and then negative). The engine should then start.
Faulty Receiver Module
If you're not getting the "Key Detected" message on your dashboard, it's possible that your receiver module has created a fault. It's the component that sends an indication to the car when the key fob is activated which acts as an immobiliser and prevents it from starting until the key that you want to use is present.
It could be due to several reasons, such as water damage or simply the aging process. If your Peugeot 308 key fob was exposed to dirty tap water, as in the electronic chip located inside may be damaged. In this instance, you'll need to remove it and clean it thoroughly using isopropyl or an electronic cleaner. Once it's dry you can put the battery back in and test it again.
