Seat Alhambra Key Problems

Seat's family MPV jumbo is among the top in class when it comes to maintaining resale value. With a brand new model on sale, the jumbo family MPV is even better.

There are a number of reasons that the key fob might not work properly, including a dead battery water damage, receiver module problems or signal interference. This article will guide you through the steps to get it working.

Water Damage

If your seat alhambra keyfob is able to survive the wash cycle or a bath in the pool or ocean it's likely to have an incredible waterproof chip, but be careful not to make this a routine as exposure to excessive water increases the chance of the key fob being damaged. If your key fob stops functioning after exposure to rain or clean tap water, take out the battery and clean the electronic component using a towel. Let it dry completely before replacing the battery. If you are exposed to soapy or salty water it is recommended to wash the chip using isopropyl alcohol or a electronic cleaner prior to attempting to insert the battery back in.

Faulty Receiver Module

If you've tried the battery of a button cell and the key fob doesn't lock or unlock then it's likely the receiver module has been faulty. The positive side is that this is a fairly easy and cost-effective fix. You can disconnect the battery for about a couple of minutes (first take off the negative cable, then press the horn button a few times) to eliminate any remaining electricity and then reconnect it in reverse order e.g. positive first, then negative cable later.

ESP Warning Light If the ESP warning light flashes, it is normal and means that the vehicle is driving through terrain where the traction of the road surface and the tyres isn't ideal, like snow, gravel or lots of surface water. If the ESP light is constantly on, it indicates that there is a flaw in the system. This can be diagnosed with a iCarsoft i908 seat OBD code reader kit. It will provide you with a a detailed fault description.

Dead Coin Battery

One of the most common reasons for the seat alhambra key to stop working is a dead coin battery. The key fob comes with tiny button cell batteries which keeps it powered. It should be replaced with a new one that has exactly the same size, voltage, and specification as the original. When replacing the battery on the key fob remove the metal clips and make sure that the contacts on the key fob are clean and free of corrosion.

If https://www.thekeylab.co.uk/seat-car-keys/ has been exposed to water, like soapy or rain, it's recommended that you remove the battery and clean the electronic chip using isopropyl alcohol or an electronic cleaner prior to installing the new battery. The chip is sensitive to moisture and may be permanently damaged. If the key fob doesn't function after replacing the battery it might be necessary to replace the key fob.

Faulty Receiver Module

If your key fob was not working after replacing the battery, but it did not function, or stopped working in a sudden manner the receiver module could be experiencing a problem. The receiver module is responsible for absorbing the radio frequency signals transmitted by your remote key fob, and convert them into electrical signals which are then processed by other modules in the car.

If the receiver module has developed a fault that prevents it from responding to any of the commands transmitted by your remote key fob. In this case the dealer will have to reprogramme the key fob as well as install an entirely new receiver.

The key fob has been sealed with rubber to prevent water from entering the electronic chip. If you immerse the key fob in soapy water or salty ocean water, the chips inside could be damaged. You can try to clean the chip by rubbing it with isopropyl alcohol or electronic cleaner, however in the event that your key fob isn't working after this, you'll have to buy a new one.

If the keys are paired but the receiver module has developed a fault, you can try restarting all of the onboard electronics by removing 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 circuit and restore their functionality.

Faulty electronic chip

The key fob is equipped with a small electronic chip which transmits a signal 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 be disabled and stop the car from starting. However, if the key fob isn't working, and you are unable to reprogram it this could be due to a faulty chip.

The chip in the key fob isn't an irreplaceable part of the device and might have to be replaced in order to get it to work again. This can be done by taking the key fob out of its housing, and using pins or needles to contact each metal retaining clip. You'll have to replace them when they're damaged or corrosion-prone. Make sure any replacement batteries have the same voltage, size, and specification as the original.
