There are a number of reasons why your key fob might not function properly including dead coin battery or water damage, receiver module problems or signal interference. This article will guide you through the steps necessary to make sure it works.
Water Damage
If your key fob for the seat alhambra can withstand washing cycles, a dip in the ocean or a pool, then it's equipped with a waterproof chip. But, you shouldn't do this often since prolonged exposure to water can increase the chance of the key fob becoming damaged. If your key fob ceases to functioning after exposure to rain or clean tap water, remove the battery and wipe the electronic component with a paper towel. Allow it to dry completely before replacing the battery. If you are exposed to soapy or salty water it is recommended to clean the chip with isopropyl alcohol or an electronic cleaner prior to trying to put the battery back in.
Faulty Receiver Module
If you've tried the battery of a button cell and the key fob cannot be locked or unlocked, it is likely that the receiver module has been faulty. It's a relatively simple and cost-effective fix. You can remove the battery with 12 volts for a couple of minutes (first take off the negative cable, then press the horn several times) to remove any remaining power. Then, reconnect it in reverse. Positive first and then negative.
ESP Warning Light - If the ESP symbol flashes, this is normal. It means that you are driving over terrain that has poor traction. This could be due to gravel, snow or surface water. If the ESP light is constantly on, it indicates that there is a flaw in the system. It is possible to identify the problem with a iCarsoft i908 seat OBD code reader kit. It will provide you with a an in-depth description of the fault.
Dead Coin Battery
A dead coin battery is among the most frequent reasons for the keys for the seat to stop working. The key fob is powered by a small button-cell battery. Replace it with a new battery that is the same dimensions, voltage and specs as the original. If TheKeyLab are replacing the battery, be sure to remove all metal retaining clips from the back of the key fob. Also make sure that the contact points are free of corrosion.
If the key fob was exposed to water (such as soapy or rain tap water) it is recommended to remove and clean the chip with an electronic cleaner or isopropylethanol before installing a brand new battery. The chip is sensitive to moisture and may be permanently damaged. If the key fob still not working after replacing the battery, it could be necessary to replace the entire key fob.
Faulty Receiver Module
If your key fob was not working after replacing the battery, but it did not function, or suddenly stopped working the receiver module could be experiencing a problem. The receiver module is responsible for capturing the radio frequency signals that are sent by your remote key fob and converting them into electrical commands that are then utilized by other modules in your car.
If the receiver module has suffered a malfunction, it will not respond to any of the commands sent by your remote key fob. In this scenario, a dealer will need to reprogramme your key fob and install a new receiver.
The key fob comes with rubber seals that stop water from entering the chip inside. If you immerse the key fob in salty or soapy water, the chips inside could be damaged. It is possible to clean the chip by applying isopropyl alcohol or electronic cleaner, however should your key fob isn't working after this, you'll have to buy a new one.
If the keys are paired but the receiver module has developed a fault, you can try restarting all the on-board electronics by removing the battery with 12 volts for a few minutes. Connect the battery in reverse (negative cable to positive first). This will reset the on-board electronic circuit and restore their functionality.
Electronic chip that is malfunctioning
The key fob comes with a tiny chip that transmits the signal from the key to the receiver module every time the key is used. If the signal isn't in line with the one that the car has stored the immobilizer is disabled and prevent the vehicle starting. If the key fob doesn't work and you aren't able to reprogram it, this could be because of an issue with the microchip.
The chip inside the key fob is not permanent to the device and may need to be replaced to function again. This can be accomplished by taking the key fob out of its housing, and then using a needle or pin to connect with each metal retaining clip. You will have to replace them when they're damaged or damaged or corroded. Make sure any replacement batteries have the same size, voltage, and specification as the original.
