There are a myriad of reasons the key fob may not function properly, such as a dead coin battery, water damage to the receiver module or signal interference. This article will guide you through the steps necessary to get it working.
Water Damage
If your seat alhambra key fob can withstand a wash cycle or a bath in the ocean or pool then it is likely to have an amazing waterproof chip. However, do not use it regularly as exposure to excessive water increases the chance of the key fob being damaged. If your key fob ceases to functioning after exposure to rain or clean tap water, take out the battery and wipe the electronic component using a towel. Dry it completely before replacing the battery. If the key fob was exposed to salty or soapy water it is recommended that you clean the chip using isopropyl or an electronic cleaner.
Faulty Receiver Module
If you've tried a new battery for a button and the key fob still isn't locked or unlocking, it is likely that the receiver module has found a fault. The positive side is that this is a simple repair that is inexpensive, you can simply disconnect the 12 volt battery for a few minutes (first remove the negative cable then press the horn button numerous times) to remove any remaining electric current, then reconnect it in reverse order e.g. Positive cable first and then negative.
ESP Warning Light - If the ESP warning light flashes, this is normal and indicates that the car is driving through terrain in which the traction between the road surface and the tyres isn't optimal, such as gravel, snow or lots of surface water. If the ESP light is always on, it means 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 the full description of the problem.
Dead Coin Battery
One of the most frequent reasons for the seat alhambra key to stop working is a dead coin battery. The key fob is powered by a tiny button-cell battery. It is recommended to replace it with a brand new one that is identical in 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 in good condition and free of corrosion.
If the key fob was exposed to water (such as soapy tap water), it is recommended that you remove and clean the chip using an electronic cleaner or isopropylethanol prior to installing a 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 may be necessary to replace the entire key fob.
Faulty Receiver Module
If your key fob has stopped working after you replaced the battery but it didn't help, or it stopped working completely suddenly, then your receiver module might have developed an issue. The receiver module takes the radio frequency signals from your remote keyfob and converts them into electrical commands which are then used by other modules inside the car.
If the receiver module has developed a fault that prevents it from responding to any of the commands issued by your remote key fob. In this instance you will require a dealer to reprogram your key fob as well as install an additional receiver.
The key fob comes with rubber seals that stop water from getting into the electronic chip inside. However, if you submerge your key fob in salted or soapy ocean water, the chips inside could be damaged. You can attempt to clean the chip by rub it with isopropyl alcohol or electronic cleaner, but in the event that your key fob isn't working after this, you'll have to purchase a replacement.
If seat key are paired but the receiver module has developed a fault you can try to reboot all of the onboard electronics by disconnecting the 12 volt battery for a short period of time. Then, reconnect the battery in reverse order (negative cable first followed by positive). This will reset the onboard electronic circuit and restore their functionality.
Electronic chip that is malfunctioning
The key fob comes with a small chip that transmits a signal from the key to the receiver module each time the key is used. If the signal isn't in line with the one 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, it could be due to a faulty microchip.
The chip in the key fob is not permanent to the device and may need to be replaced to get it working again. This can be accomplished by taking the key fob out of its case, and using pins or needles to touch each metal clip. You will have to replace them when they're damaged or corrosion-prone. Make sure that any replacement batteries have the same voltage, size, and specification as the original.
