Seat Alhambra Key Problems
Seat's jumbo MPV family is among the top in its class when it comes down to resales values. And with a new model now available, it's even better.
There are a variety of reasons that the key fob might not work properly including dead coin battery water damage, receiver module issues, or signal interference. This article will guide you through the steps necessary to get it working.
Water Damage
If your seat alhambra key fob is able to withstand a wash cycle or a bath in the ocean or pool then it probably has an incredible waterproof chip, but 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, remove the battery and wipe the electronic component using a towel. Let it dry completely before replacing the battery. If the key fob has been exposed to soapy or salty water, it is recommended that you clean the chip using isopropyl or an electronic cleaner.
Faulty Receiver Module
If you've tried the battery of a button cell and the key fob cannot be locked or unlocked, it's likely that your receiver module has developed a fault. The good news is that it is a fairly easy and cost-effective fix. You can simply disconnect the 12 volt battery for several minutes (first remove the negative cable then press the horn button numerous times) to drain any residual electricity, and then connect it in reverse order e.g. positive first, then negative cable later.
ESP Warning Light If the ESP warning symbol flashes this is normal and signifies that the car is traveling on terrain where the traction of the road surface and tyres is not ideal like snow, gravel or a lot of surface water. If the ESP warning light is continuously flashing, it means there is an error within the system and should be diagnosed using a iCarsoft i908 Seat OBD Code Reader kit which will give you a specific fault description.
Dead Coin Battery
One of the most common reasons for the seat alhambra keys to stop working is a dead battery. The key fob is powered by a tiny button-cell battery. Replace it with a brand new battery that is the same dimensions, voltage and specs 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 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 using an electronic cleaner or isopropyl alcohol prior to installing a new battery. The chip is sensitive to moisture and may 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.
Faulty Receiver Module

If your key fob has stopped working after you replaced the battery and it didn't help, or if it suddenly stopped working suddenly it is possible that your receiver module could 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 followed by other modules in the car.
If the receiver module is defective, it will not accept any commands from your remote key fob. In this case the dealer will have to reprogram your key fob and install a new receiver.
The key fob has been sealed by rubber to block water from getting inside the electronic chip. If you immerse your key fob in the ocean's salty or soapy water, the chip inside could be damaged. If your key fob isn't able to work, you can try cleaning the chip using isopropyl or electronic cleaner.
If the keys are connected but the receiver module has developed a fault you can try to reboot all of the electronics on board by disconnecting the battery at 12 volts for a few minutes. Connect the battery in reverse (negative cable to positive first). This will reset the on-board electronic and restore their functionality.
Electronic Chip Faulty
The key fob is equipped with tiny electronic chips that sends a signal to the receiver module when the key is used. If the signal does not match the one that the car has stored, the immobilizer will disable and stop the vehicle from starting. If the key fob doesn't work and you aren't able to reprogram it, this could be because of a faulty microchip.
seat car key case inside the key fob is not a permanent part of the device and may need to be replaced in order to function again. The best way to do this is to remove the key from its housing and then using a pin needle to connect with each of the clips made of metal. You will require replacement in the event that they have been damaged or corrosion-prone. Make sure that any replacement batteries have the same size, voltage, and specification as the original.
Seat Alhambra, a popular and well-designed model, may be troublesome due to certain parts or equipment. For example there are owners who have had problems with the automatic climate control system, which could malfunction and cause problems in a specific setting. The infotainment system could also malfunction and freeze the screens.
