There are a variety of reasons why your key fob might not work properly including dead coin battery, damage to the receiver module, water problems or signal interference. This article will guide you through the steps to get it back to working.

Water Damage

If your seat alhambra keyfob is able to survive a wash cycle or a bath in the pool or ocean then it is likely to have an amazing waterproof chip but do not make it a habit since exposure to excessive water increases the risk of the key fob becoming damaged. If the key fob ceases to functioning after exposure to clean tap water or rain, simply take out the battery, clean the electronic component with paper towel and allow it to dry completely before putting the battery back into. If the key fob has been exposed to soapy or salty water it is recommended you clean the chip with isopropyl or an electronic cleaner.

Faulty Receiver Module

If you've tried a new button cell battery and the key fob doesn't lock or unlock then it's likely that the receiver module has discovered a problem. The positive side is that this is a fairly easy repair that is inexpensive, you can disconnect the 12 volt battery for a few minutes (first take off the negative cable, then press the horn button numerous times) to remove any remaining electricity, and then connect it in reverse order e.g. Positive cable first and then negative.

ESP Warning Light If the ESP warning symbol flashes this is normal and means that the car is traveling on terrains where the traction between the road surface and tyres aren't as good, like snow, gravel or lots of surface water. If the ESP warning light remains blinking, it indicates that there is a fault within the system. It should be detected with a iCarsoft i908 Seat OBD Code Reader which will give you a specific fault description.

Dead Coin Battery

A dead coin battery is among the most common reasons for the keys for the seat to stop working. The key fob is powered by a small button-cell battery. It is recommended to replace it with a new one that is exactly the same size, voltage and specifications as the original. If you're replacing the battery, ensure that you remove all metal retaining clips from the back of the key fob. Also, make sure that the contacts 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 with an electronic cleaner or isopropyl ethanol 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 could be necessary to replace the entire key fob.

Faulty Receiver Module

If your key fob stopped functioning after replacing the battery, but it didn't work, or stopped working abruptly your receiver module might have encountered a problem. The receiver module receives radio frequency signals from your remote keyfob and converts them into electrical commands that are then processed by other modules within 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 case you'll need to go to a dealer for reprogramming the key fob, and also a new receiver module.

The key fob has been sealed with rubber to prevent water from entering the electronic chip. If you submerge the key fob in soapy or salty water, it may damage the chips. If your key fob isn't able to work, try cleaning the chip with isopropyl or electronic cleaner.

If the keys have been linked, but the receiver module is malfunctioning, you can try to restart all of the electronics on board by disconnecting the battery at 12 volts for few minutes. Connect the battery in reverse (negative cable to positive first). This will reset the onboard electronic and restore their functionality.

Electronic chip that is malfunctioning

The key fob comes with a tiny chip that transmits an indication from the key to the receiver module every time the key is used. If the signal does not match the one the car has stored the immobilizer is disabled and prevent the vehicle from starting. If the key fob doesn't work and you are unable to reprogram it, this could be due to an issue with the microchip.

The chip inside the key fob is not permanent to the device, and might need to be replaced in order to function again. This can be done by taking the key fob away from its housing and using pins or needles to connect with each metal retaining clip. If the clips are corroded, or damaged, you'll need to replace them in order for the remote control to work. Make sure that the replacement batteries have the same voltage, size, and specification as the original.
