Seat's jumbo family MPV is one of the best in the market when it comes to conserving resale value. With a new model available for sale the family MPV jumbo is better.
There are a variety of reasons that the key fob could not function properly, such as a dead coin battery or damage to the receiver module, water issues, or signal interference. This article will guide you through the steps needed to make it work again.
Water Damage
If your seat alhambra keyfob is able to survive an wash cycle or bath in the ocean or pool then it is likely to have an incredible waterproof chip, but do not make it a habit because prolonged exposure to water increases the chance of the key fob being damaged. If the key fob stops working after exposure to clean water from the tap or rain, just take out the battery, clean the electronic component with a towel and let it dry completely before putting the battery back into. If the key fob has been exposed to salty or soapy water and salty water, it is recommended you clean the chip with isopropyl or electronic cleaner.
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 an issue. TheKeyLab is that it is a relatively simple and cost-effective fix. You can disconnect the 12 volt battery for about a couple of minutes (first take off the negative cable, then press the horn button multiple times) to remove any remaining electricity and then reconnect it in reverse order e.g. Positive first and then negative.
ESP Warning Light If the ESP warning light flashes, it is normal and indicates that the car is driving on terrains where the traction between the road surface and the tyres aren't as good, such as snow, gravel or lots of surface water. If the ESP warning light is constantly illuminated it indicates that there is a problem within the system. This can be detected with a iCarsoft i908 Seat OBD Code Reader kit that will give you a specific fault description.
Dead Coin Battery
One of the most common reasons for the seat alhambra key not working is a dead battery. The key fob comes with an insignificant button cell battery which keeps it powered. It should be replaced with a brand new one with the same size, voltage, and specification as the original. If you are replacing the battery, be sure to remove all metal clips from the back of the key fob. You should 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 can be permanently damaged by moisture. If the key fob doesn't work after replacing the battery it might be necessary to replace the key fob.
Faulty Receiver Module
If your key fob stopped functioning after replacing the battery but it didn't work, or if it stopped working suddenly the receiver module could have encountered a problem. The receiver module takes the radio frequency signals from your remote keyfob and converts them into electrical commands which are then acted upon by other modules inside the car.
If the receiver module has suffered a malfunction that prevents it from responding to any of the commands received by your remote key fob. In this instance, you will have to visit a dealer to reprogramme the key fob, and also a new receiver module.
The key fob features rubber seals that stop water from entering the electronic chip inside. If you immerse the key fob in salty or soapy water, it could cause damage to the chip. You can try cleaning the chip by rub it with isopropyl alcohol or electronic cleaner, but If your key fob does not work after this, you'll have to purchase a replacement.
If the keys have been paired, but the receiver module is malfunctioning then you can restart all of the electronics on board by disconnecting the 12-volt battery for a few minutes. Then reconnect the battery in reverse order (negative cable first, then positive). This will reset the on-board electronic and restore their functionality.
Faulty Electronic Chip
The key fob has an electronic chip that transmits a message to the receiver module each time 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 stop the vehicle from beginning. If the key fob won't function and you are not able to reprogram it, it could be because of a malfunctioning microchip.
The chip in the key fob may need to be changed to allow it to function again. This can be done by removing the key fob from its case, and using pins or needles to connect with each metal retaining clip. You'll need to replace these in the event that they have been damaged or damaged or corroded. Make sure that the replacement batteries are of the same size, voltage and specifications as the original.
