There are a variety of reasons that the key fob may not function properly, such as a dead coin battery or damage to the receiver module, water problems or signal interference. This article will guide you through the steps necessary to fix it. Water Damage If your seat alhambra key fob can withstand washing cycles or a bath in the ocean or pool then it is likely to have an amazing waterproof chip but be careful not to make this a routine since exposure to excessive water increases the chance of the key fob becoming damaged. If your key fob stops functioning after being exposed to rain or clean tap water, you should remove the battery and wipe the electronic component using a paper towel. Dry it completely before replacing the battery. In case of exposure to soapy or salty water, it is recommended to clean the chip with isopropyl alcohol or an electronic cleaner before attempting to put the battery back in. Faulty Receiver Module If you've tried a new button cell battery and the key fob isn't locked or unlocking, it's likely that your receiver module has discovered a problem. The good news is that this is a relatively simple and inexpensive repair, you can just disconnect the battery for just a few minutes (first remove the negative cable then press the horn button several times) to eliminate any remaining electrical current and then reconnect it in reverse order e.g. positive cable first then negative cable later. ESP Warning Light – If the ESP symbol blinks, it is normal. It is a sign that you are driving on a terrain that has poor traction. This could be due to snow, gravel or surface water. If the ESP light is always 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 a detailed fault description. Dead Coin Battery A dead coin battery is among the most common reasons for the keys for the seat to cease to function. The key fob is powered by a tiny button-cell battery. 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 the metal clips and make sure that the contacts of the key fob are free of corrosion and clean. If the key fob was exposed to water, like soapy or rain, it's recommended that you remove the battery and clean the electronic chip with isopropyl alcohol or a electronic cleaner prior to putting in the new battery. The chip is sensitive to moisture and could be permanently damaged. If the key fob doesn't function after replacing the battery, it might be necessary to replace the key fob. Faulty Receiver Module If your key fob has stopped working after replacing the battery, but it did not work, or stopped working in a sudden manner, your 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 convert them into electrical signals that are then utilized by other modules in the car. If the receiver module has suffered a malfunction it will not respond to any of the commands received by your remote key fob. In this situation the dealer will have to reprogram your key fob, and also install a new receiver. The key fob features rubber seals that prevent water from getting into the chip inside. If you immerse the key fob in salted or soapy ocean water, the chips inside may be damaged. If your key fob doesn't work, try cleaning the chip with isopropyl or electronic cleaner. If the keys have been successfully paired, but your receiver module isn't working, you can try to restart all the electronics on board by disconnecting the battery at 12 volts for couple of minutes. Then, reconnect the battery in reverse order (negative cable first followed by positive). This will reset all electronic components on board and restore their functionality. Faulty electronic chip The key fob is fitted with a tiny chip which transmits an indication from the key to the receiver module every time the key is used. If the signal does not match the one that the car has stored the immobilizer will be disabled and prevent the vehicle from starting. If the key fob isn't working and you are not able to reprogram it, it could be due a damaged chip. The chip inside the key fob is not an irreplaceable part of the device, and might need to be replaced in order to get it to work again. The best way to do this is by removing the key from its housing and then using a pin or needle to contact each of the metal retaining clips. You will need to replace these if they are damaged or damaged or corroded. Make sure that any replacement batteries have the same size, voltage, and specifications as the original one.
