Seat Alhambra Key Problems
Seat's jumbo MPV family is among the best in its class when it comes to resale value. And with a new model now available it's even better.
There are a myriad of reasons the key fob might not perform as it should, including the battery being dead or damage to the receiver module, or signal interference. This article will guide you through the steps needed to get it back to working.
Water Damage
If your key fob for the seat alhambra survives washing cycles or a dip in the ocean or a pool, then it has a waterproof chip. But be careful not to do this often because prolonged exposure to water increases chances that the key fob will be damaged. If your key fob stops working after exposure to rain or clean tap water, remove the battery and clean the electronic component with a paper towel. Allow it to dry completely before replacing the battery. If seat replacement key has been exposed to salty or soapy water, it is recommended that you clean the chip using isopropyl or an electronic cleaner.
Faulty Receiver Module
If you have tried the battery of a button cell and the key fob does not lock or unlock, it's likely the receiver module has developed a fault. It's a relatively simple and cost-effective fix. It is possible to disconnect the battery with 12 volts for a few minutes (first remove the negative cable and then press the horn a few times) to eliminate any remaining power. Then connect it in reverse. Positive first followed by negative.
ESP Warning Light - If the ESP warning light flashes, it is normal and indicates that the car is driving on terrains where the traction between the road surface and tyres isn't ideal, such as gravel, snow or a lot of surface water. If the ESP warning light remains shining, it is a sign that there is an error within the system. This can be identified using an iCarsoft i908 Seat OBD Code Reader, which will provide you with a specific fault description.
Dead Coin Battery
One of the most common reasons for the seat alhambra key to stop working is a dead battery. The key fob has a small button cell battery that keeps it powered. Replace it with a new battery with the same size, voltage and specifications as the original. If you're replacing the battery, be sure to remove all metal retaining clips from the back of the key fob. You should also make sure that the contact points are free of corrosion.
If the key fob has been exposed water, such as soapy or rain it is recommended to take the battery off and clean the electronic chip using isopropyl alcohol or an electronic cleaner prior to putting in the new battery. The chip may be permanently damaged by moisture. If the key fob still doesn't function 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 and it didn't help, or if it suddenly stopped working without notice The receiver module might have developed an issue. The receiver module is responsible to receive the radio frequency signals that are sent by your remote key fob and changing them into electrical signals which are then processed by other modules in the car.
If the receiver module has developed a fault and is unable to respond to any of the commands received by your remote key fob. In this scenario you'll need to go to a dealer to reprogram the key fob, and also a new receiver module.
The key fob is fitted with rubber seals that stop water from getting into the electronic chip inside. If you dip the key fob into soapy or salty water, it could cause damage to the chip. You can try to clean the chip by rubbing it with isopropyl alcohol or electronic cleaner, however if your key fob still isn't working after all this, you'll have to purchase a replacement.
If the keys are paired but the receiver module has developed a fault, you can try to reboot all 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 onboard electronic circuit and restore their functionality.
Electronic chip that is malfunctioning
The key fob is equipped with an electronic chip that transmits 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 be disabled and stop the car from starting. If the key fob isn't working, and you can't reprogram it, it could be due to a malfunctioning chip.
The chip in the key fob is not permanent to the device and might have to be replaced in order to make it work again. The most effective method for doing this is by removing the key from its housing and then using a pin or needle to get into contact with each of the retaining clips made of steel. You will have to replace them in the event of damage or damaged or corroded. Make sure that the replacement batteries are of the same size, voltage and specifications as the original.
