If your key fob for the seat alhambra can withstand an wash cycle or a dip in the ocean or a pool then it has a waterproof chip. But don't do this often because prolonged exposure to water can increase chances that the key fob will be damaged. If the key fob ceases to functioning after exposure to clean tap water or rain then simply remove the battery, clean the electronic component using a paper towel and let it dry completely before putting the battery back in. If the key fob has been exposed to soapy or salty water it is recommended that you clean the chip with isopropyl or an electronic cleaner.

Faulty Receiver Module

If you've tried an entirely new battery for your button and the key fob cannot be locked or unlocked, it's likely that the receiver module has found a fault. It's a simple and affordable fix. It is possible to disconnect the battery with 12 volts for a few minutes (first take off the negative cable, then press the horn a few times) to drain any remaining electricity. Then connect it in reverse. positive cable first, then negative cable later.

ESP Warning Light - If the ESP symbol flashes, this is normal. It indicates that you are driving on terrain that has poor traction. This could be caused by snow, gravel or surface water. If the ESP light is always flashing, it is a sign there is a problem with the system. This can be diagnosed with a iCarsoft i908 seat OBD code reader kit. It will provide detailed information about the fault.

Dead Coin Battery

One of the most common reasons for the seat alhambra key to stop functioning is a dead coin battery. The key fob is powered by a small button-cell battery. It is recommended to replace it with a new one that is the same size, voltage, and specification as the original. When replacing the battery on the key fob, remove all metal clips and ensure that the contacts of the key fob are free of corrosion and clean.

If the key fob has been exposed water, such as rain or soapy water, it's recommended that you remove the battery and clean the electronic chip with alcohol isopropyl or an electronic cleaner prior to putting in the new battery. The chip is sensitive to moisture and could be permanently damaged. If the key fob is still not working after replacing the battery, it may be necessary to replace the entire key fob.

Faulty Receiver Module

If your key fob stopped working after replacing the battery, but it didn't work, or if it suddenly stopped working, your receiver module could have experienced a malfunction. The receiver module is responsible for receiving 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, it will not respond to any of the commands received by your remote key fob. In this scenario you will require a dealer to reprogram your key fob, and also install the new receiver.

The key fob is fitted with rubber seals to prevent water from entering the electronic chip inside. If you submerge the key fob in salted or soapy water it could damage the chip. You can try cleaning the chip by rub it with isopropyl alcohol or electronic cleaner, but if your key fob still isn't working after all this, you'll have to buy a new one.

If the keys have been paired, but the receiver module is malfunctioning, you can try to restart all the electronics on board by disconnecting the 12-volt battery for a few minutes. Then, reconnect the battery in reverse order (negative cable first and then positive). This will reset the on-board electronic circuit and restore their functionality.

Faulty electronic chip

The key fob comes with a tiny chip which transmits the signal from the key to the receiver module each time the key is used. If the signal doesn't match the one recorded by the car the immobilizer is able to shut off the engine and prevent the vehicle from starting. However, if the key fob isn't working and you can't reprogram it this could be due a damaged chip.

The chip in the key fob may have change to allow it to function again. This can be accomplished by taking the key fob out of its housing, and using a needle or pin to make contact with each metal retaining clip. If they are corroded or damaged, you'll have to replace them to allow the remote control to work. Make sure the replacement batteries are of the same voltage, size, and specification as the original.
