Seat Alhambra Key Problems
Seat's Jumbo MPV family is among the top models in its class when it comes to resale value. And with a new model now available it's even more impressive.
There are many reasons the key fob might not work as expected, including a dead coin battery or damage to the receiver module, or signal interference. This article will guide you through the steps needed to get it working again.
Water Damage

If your seat alhambra keyfob is able to survive an wash cycle or bath in the pool or ocean then it is likely to have an amazing waterproof chip but don't make this a habit since exposure to excessive water increases the risk of the key fob being damaged. If your key fob stops functioning after exposure to rain or clean tap water, unplug the battery and clean the electronic component using a towel. Let it dry completely before replacing the battery. If the key fob was exposed to soapy or salty water it is recommended that you clean the chip with isopropyl or an electronic cleaner.
Faulty Receiver Module
If the key fob does not lock or unlock after you've replaced the battery of the button, it is possible that the receiver module is suffering from an issue. The good thing is that this is a fairly easy and inexpensive repair, you can simply remove the battery 12 volts for a few minutes (first take off the negative cable then press the horn button several times) to remove any remaining electricity and then reconnect it in reverse order e.g. Positive first, then negative.
ESP Warning Light If the ESP warning light flashes, it is normal and means that the car is driving over terrain in which the traction between the road surface and the tyres isn't optimal, such as gravel, snow or a lot of surface water. If the ESP light is always on, it means that there is a problem in the system. It is possible to identify the problem with a iCarsoft i908 seat OBD code reader kit. It will provide you with a an in-depth description of the fault.
Dead Coin Battery
One of the most common reasons for the seat alhambra key not working is a dead coin battery. The key fob contains a tiny button cell battery that keeps it running. Replace it with a new battery that is the same size, voltage, and specifications as the original. If you're replacing your battery, be sure to remove all metal retaining clips from the back of the key fob. You should also make sure the contacts are free of corrosion.
If the key fob was exposed to water, such as rain or soapy water, it's recommended that you take the battery off and clean the electronic chip with alcohol or an electronic cleaner before putting in the 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 might be necessary to replace the entire key fob.
Faulty Receiver Module
If your key fob stopped working after replacing the battery and it didn't help, or it stopped working completely out of the blue the receiver module may have developed a fault. The receiver module receives the radio frequency signals from your remote keyfob, and transforms them into electrical signals that are then processed by other modules inside the car.
If the receiver module has developed a fault it will not respond to any of the commands received by your remote key fob. In this instance you'll be required to visit a service for reprogramming the key fob, and also a new receiver module.
The key fob is covered with rubber to stop water from leaking into the electronic chip. If you submerge the key fob into salty or soapy water, it may damage the chips. If your key fob won't work, you could try cleaning the chip with isopropyl or an electronic cleaner.
If the keys are connected but the receiver module has developed a fault you can try rebooting all electronics on board by removing 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 circuits and restore their functionality.
Faulty electronic chip
The key fob contains tiny electronic chips that transmits a message to the receiver module each time the key is used. If the signal received does not coincide with the one stored by the car the immobilizer will stop the engine and stop the vehicle from starting. If the key fob you purchased does not work and you are unable to reprogram it, this could be due to an issue with the microchip.
The chip inside the key fob may need to be replaced to make it work again. The best way to do this is by removing the key from its housing and then using a pin or needle to make contact with each of the metal clips that hold it. G28CarKeys will need to replace these in the event of damage or corrosion-prone. Make sure that the replacement batteries have the same voltage, size and specification as the original.
The Seat Alhambra is a well-designed and popular model but like any other car it can occasionally experience issues with particular parts or equipment. For instance there have been reports of owners experiencing problems with the climate control system, which may be faulty and get stuck in a particular setting. Similarly, the infotainment system has also been reported to malfunction and freeze screens.
