There are a variety of reasons why the key fob could not perform as it should, including an inoperative coin battery or damage to the receiver module or signal interference. This article will walk you through the steps to make it work again. Water Damage If your key fob for the seat alhambra can withstand a wash cycle or a dip in the ocean or a pool, then it's equipped with a waterproof chip. However, don't do it often since prolonged exposure to water increases the likelihood that the key fob will be damaged. If your key fob ceases to working after exposure to rain or clean tap water, take out the battery and wipe the electronic component using a paper towel. Allow it to dry completely before replacing the battery. In case of exposure to soapy or salty water, it is recommended to wash the chip with isopropyl alcohol or electronic cleaner prior to attempting to put the battery back in. Faulty Receiver Module If the key fob does not lock or unlock after you have replaced the button cell battery, it is possible that the receiver module has a fault. It's a simple and affordable fix. You can unplug the battery that is 12 volts for a few minutes (first remove the negative cable, then press the horn several times) to eliminate any remaining power. Then, reconnect it in reverse. Positive cable first, then negative. ESP Warning Light – If the ESP warning light flashes, this is normal and indicates that the car is travelling over terrain where the traction between the road surface and tyres isn't ideal, such as gravel, snow or lots of surface water. If the ESP light is constantly on, it means that there is a flaw in the system. This can be identified 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 One of the most frequent reasons for the seat alhambra keys to stop working is a dead battery. The key fob contains a tiny button cell battery that keeps it powered. Replace it with a brand new battery with the same size, voltage and specifications as the original. When replacing the battery on the key fob remove all metal clips and ensure that the contacts on the key fob are clean and free of corrosion. If the key fob was exposed to water (such as rain or soapy tap water), it is recommended to remove and clean the chip using an electronic cleaner or isopropylethanol before installing a new battery. The chip may be permanently damaged by water. If the key fob is still not working after replacing the battery, it might 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 work, or suddenly stopped working, your receiver module could have encountered a problem. The receiver module is responsible for absorbing the radio frequency signals sent by the remote key fob and converting them into electrical commands that are then acted on by other modules within the car. If the receiver module has suffered a malfunction it will not respond to any of the commands transmitted by your remote key fob. In this situation you'll be required to visit a service for reprogramming your key fob as well as a new receiver module. The key fob is covered with rubber to stop water from entering the electronic chip. However, if you submerge your key fob into the ocean's salty or soapy water, the chip inside may be damaged. You can try to clean the chip by applying isopropyl alcohol or electronic cleaner, however if your key fob still isn't working after all this, then you'll need to buy a new one. If the keys are in a pair but the receiver module has developed a fault you can try restarting all of the electronics on board by removing the 12 volt battery for a few minutes. Then, reconnect seat car keys in reverse order (negative cable first followed by positive). This will reset all electronics onboard and will bring them back into operation. Electronic chip that is malfunctioning The key fob houses tiny electronic chips that sends a signal to the receiver module when the key is used. If the signal received does not match the one stored by the car the immobilizer is able to shut off the engine and prevent the vehicle from beginning. If the key fob isn't working and you are unable to reprogram it this could be due to a defective chip. The chip in the key fob isn't an indefinite part of the device and might have to be replaced in order to make it work again. This can be done by taking the key fob away from its housing, and using a needle or pin to contact each metal retaining clip. If the clips are corroded, or broken, you will require replacement in order for the remote control to function. Make sure that any replacement batteries are the same size, voltage, and specifications as the original. The Seat Alhambra is a well-designed and popular model however, just like any other vehicle it is not without its challenges. issues with particular parts or equipment. For instance there are owners who have had problems with the automatic climate control system, which can become faulty and stuck in a specific setting.
