Seat Alhambra Key Problems

seat arona key's jumbo MPV range is among the best in its class when it comes down to resale value. And with a brand new model now available it's even better.

There are a number of reasons why the key fob might not function correctly, including dead battery, water damage, receiver module issues, or signal interference. This article will walk you through the steps to get it back to working.

Water Damage

If your key fob for the seat alhambra can withstand a wash cycle or dip in the water or a pool, it has a waterproof chip. But, you shouldn't do this often, as prolonged exposure to water can increase the likelihood of the key fob becoming 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 with a paper towel. Allow it to 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 before attempting to put the battery back in.

Faulty Receiver Module

If the key fob does not lock or unlock after having replaced the button cell battery it is possible that the receiver module is suffering from an issue. The good news is that this is a relatively simple and cost-effective fix. You can just disconnect the 12 volt battery for about a couple of minutes (first take off the negative cable, then press the horn button a few times) to drain any residual electrical current and then reconnect it in reverse order e.g. Positive first, then negative.

ESP Warning Light - If the ESP warning symbol flashes this is normal and indicates that the car is travelling on terrain where the traction between the road surface and the tyres aren't as good, such as snow, gravel or lots of surface water. If the ESP light is always on, it is a sign that there is a fault in the system. This can be diagnosed by using an iCarsoft i908 seat OBD code reader kit. It will give you a detailed fault description.

Dead Coin Battery

A dead battery for the coin is one of the most frequent reasons for the seat alhambra keys to cease to function. The key fob contains an insignificant button cell battery that keeps it running. Replace it with a new battery that has the exact size, voltage and specifications as the original. If you are replacing the battery, ensure that you remove all metal retaining clips from the back of the key fob. You should also make sure that the contact points are clean and free of corrosion.

If the key fob has been exposed water, like rain or soapy water it is recommended to take the battery off and clean the electronic chip using isopropyl alcohol or a electronic cleaner prior to putting in the new battery. The chip may be permanently damaged by moisture. If the key fob isn't working after replacing the battery it might be necessary to replace the key fob.

Faulty Receiver Module

If your key fob stopped functioning after replacing the battery, but it didn't work, or stopped working in a sudden manner the receiver module may be experiencing a problem. The receiver module takes the radio frequency signals from the remote keyfob and converts them into electrical commands which are then used by other modules inside the car.

If the receiver module has suffered a malfunction, it will not respond to any of the commands sent by your remote key fob. In this scenario, you will have to visit a dealer for reprogramming of the key fob, and also a new receiver module.

The key fob has rubber seals that prevent water from entering the electronic chip inside. If you dip the key fob into soapy or salty water, it may damage the chips. If your key fob isn't able to function, you can try cleaning the chip using isopropyl or an electronic cleaner.

If the keys have been paired but the receiver module has developed a fault you can try to reboot all electronics on board by removing the battery at 12 volts for a short period of time. Connect the battery in reverse (negative cable to positive first). This will reset all electronics onboard and will restore their functionality.

Electronic chip that is malfunctioning

The key fob contains an electronic chip that transmits a signal to the receiver module every time the key is used. If the signal does not match the one the car has stored the immobilizer is disabled and prevent the vehicle starting. If the key fob doesn't work and you aren't able to reprogram it, this could be because of a malfunctioning microchip.

The chip inside the key fob could need change in order to make it function properly. This can be done by taking the key fob away from its housing, and then using a needle or pin to contact each metal retaining clip. You will require replacement in the event of damage or corroded. Make sure that any replacement batteries have the same size, voltage and specifications as the original one.
