Seat Alhambra Key Problems
Seat's jumbo family MPV is among the top in the class in terms of maintaining resale value. With a new model currently on sale the jumbo family MPV is even better.
There are a variety of reasons why the key fob might not work properly, such as a dead coin battery water damage, receiver module problems or signal interference. This article will walk you through the steps to get it working again.
Water Damage
If your key fob for the seat Alhambra is able to withstand an wash cycle or a dip in the ocean or a pool then it's got a waterproof chip. But, you shouldn't do this often as excessive exposure to water increases the risk that the key fob will be damaged. If the key fob ceases to functioning after exposure to clean water from the tap or rain, simply take out the battery, wipe the electronic component with a towel and allow it to dry completely before putting the battery back in. If the key fob has been exposed to soapy or salty water it is recommended you clean the chip using isopropyl or an electronic cleaner.
Faulty Receiver Module
If the key fob will not lock or unlock after you've replaced the battery in the button cell it is possible that the receiver module is suffering from an issue. The good news is that this is a simple and cost-effective fix. You can just 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 electricity and then reconnect it in reverse order e.g. Positive cable first followed by negative.
ESP Warning Light - If the ESP warning symbol flashes this is normal and signifies that the car is traveling on terrain in which the traction between the road surface and tyres is not ideal like gravel, snow or a lot of surface water. If the ESP warning light continues to be blinking, it indicates that there is an error within the system and should be detected using an iCarsoft i908 Seat OBD Code Reader, which will provide a precise fault description.
Dead Coin Battery
A dead battery for the coin is one of the most frequent causes for the keys for the seat to stop working. The key fob is powered by an insignificant button cell battery that is able to keep it powered. It is recommended to replace it with a replacement with exactly the same size, voltage and specifications as the original. If you're replacing your battery, ensure that you remove all metal retaining clips from the back of the key fob. You should also make sure that the contacts are free of corrosion.
If the key fob was exposed to water (such as 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 can be permanently damaged. If the key fob is still not working after replacing the battery, it might be necessary to replace the entire key fob.

If your key fob stopped functioning after replacing the battery, but it didn't work, or if it suddenly stopped working, your receiver module could be experiencing a problem. The receiver module is responsible to receive the radio frequency signals sent by your remote key fob, and transform them into electrical commands that are then used by other modules in the car.
If the receiver module has developed a fault that prevents it from responding to any of the commands received by your remote key fob. In this case you will require a dealer to reprogramme the key fob, and also install an entirely new receiver.
The key fob features rubber seals that block water from getting into the chip inside. If you immerse the key fob in salted or soapy water it could cause damage to the chip. It is possible to clean the chip by rub it with isopropyl alcohol or electronic cleaner, but should your key fob does not work after this, you'll have to buy a new one.
If the keys are successfully paired, but your receiver module is faulty it is possible to restart all the electronics that are on board by disconnecting the 12-volt battery for a couple of minutes. Then, reconnect the battery in reverse order (negative cable first before positive). This will reset all electronic components onboard and restore their functionality.
A malfunctioning electronic chip
The key fob is outfitted with a tiny chip that transmits an indication from the key to the receiver module each time the key is used. If the signal doesn't match the one that the car has stored, the immobilizer will disable and stop the car from starting. If the key fob does not function and you are not able to reprogram it, this could be due to an incompatible microchip.
The chip inside the key fob isn't an irreplaceable part of the device, and might need to be replaced in order to function again. This can be accomplished by taking the key fob out of its housing and using pins or needles to make contact with each metal retaining clip. You will require replacement in the event of damage or damaged or corroded. Make sure the replacement batteries are of the same voltage, size, and specification as the original.
The Seat Alhambra is a popular and well-designed car however, just like any other vehicle, it can sometimes experience issues with particular components or equipment. For example some owners have encountered issues with the automatic climate control system, which could fail and become stuck in one particular setting. The infotainment system may also malfunction and freeze the screens.
