Seat Alhambra Key Problems

Seat's Jumbo MPV family is among the top in its class when it comes down to resale values. With a new model on sale the jumbo family MPV is even more impressive.

There are a myriad of reasons why the key fob could not function properly, including a dead battery, water damage, receiver module issues or signal interference. This article will guide you through the steps necessary to fix it.

Water Damage

If your key fob for the seat alhambra survives washing cycles, a dip in the water or a pool, it is equipped with a waterproof chip. But don't do this often, as prolonged exposure to water increases the likelihood of the key fob getting damaged. If your key fob ceases to working after exposure to rain or clean tap water, take out the battery and wipe the electronic component using a paper towel. Let it dry completely before replacing the battery. In the event of exposure to soapy water or salt, it is recommended that you clean the chip with isopropyl alcohol or electronic cleaner prior to attempting to put the battery back in.

Faulty Receiver Module

If the key fob will not lock or unlock even after you've replaced the battery for the button, it is possible that the receiver module is suffering from an issue. The positive side is that this is an easy and inexpensive repair, you can just disconnect the battery for just a few minutes (first remove the negative cable and press the horn button numerous times) to eliminate any remaining electricity, and then connect it in reverse order e.g. Positive cable first and then negative.

ESP Warning Light – If the ESP symbol blinks, it is normal. It means that you're driving on terrain with poor traction. This could be due to gravel, snow or surface water. If the ESP light is constantly on, it is a sign that there is a problem with the system. It can be detected with a iCarsoft i908 seat keys OBD code reader kit. It will give you detailed information about the fault.

Dead Coin Battery

A dead coin battery is one of the most common reasons for the seat alhambra keys to cease to function. The key fob contains a tiny button cell battery that keeps it powered. It should be replaced by a new battery with identical in size, voltage and specifications as the original. If you're replacing your battery, ensure that you remove all metal clips from the back of the key fob. You should also make sure that the contacts are clean and 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 using an electronic cleaner or isopropyl ethanol before installing a brand new battery. The chip is sensitive to moisture and can be permanently damaged. If the key fob doesn't work after replacing the battery, it may be necessary for you to replace the key fob.

Faulty Receiver Module

If your key fob has stopped working after replacing the battery, but it didn't help, or if it stopped working completely suddenly The receiver module could have developed a fault. The receiver module is responsible for receiving the radio frequency signals transmitted by the remote key fob and changing them into electrical signals which are then processed by other modules in 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 situation, you will need to go to a dealer to reprogram your key fob as well as a new receiver module.

The key fob is fitted with rubber seals to prevent water from entering the chip inside. If you immerse your key fob in the ocean's salty or soapy water, the chip inside may 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 is not working it is possible to restart all the electronics that are on board by disconnecting the battery that is 12 volts for a few minutes. Connect the battery in reverse (negative cable to positive first). This will reset all the electronic components on board and restore their functionality.

Electronic Chip Faulty

The key fob is fitted with a tiny chip which transmits an indication from the key to the receiver module each time the key is used. If the signal does not match the one that the car has stored, the immobilizer will disable and prevent the vehicle starting. If the key fob does not function and you are not able to reprogram it, this could be due to an issue with the microchip.

The chip in the key fob could need to be replaced to make it work again. This can be accomplished by taking the key fob out of its housing, and then using pins or needles to make contact with each metal retaining clip. You will need to replace these when they're damaged or corroded. Make sure any replacement batteries are of the same voltage, size, and specification as the original.
