Water Damage

If your seat alhambra keyfob is able to survive washing cycles or a bath in the pool or ocean then it probably has an amazing waterproof chip.

Allow it to dry completely before replacing the battery. If the battery is exposed to soapy or salty water it is recommended that you clean the chip with alcohol, isopropyl or electronic cleaner prior to attempting to insert the battery back in.

Faulty Receiver Module

If you've tried an entirely new battery for your button and the key fob still isn't locked or unlocking, it's likely that your receiver module has found a fault. The good thing is that this is a simple repair that is inexpensive, you can remove the battery 12 volts for several minutes (first remove the negative cable and then press the horn button numerous times) to drain any residual electricity, and then connect it in reverse order e.g. Positive first and then negative.

ESP Warning Light - If the ESP symbol is illuminated, this is normal. It indicates that you're driving on terrain with poor traction. This could be caused by snow, gravel or surface water.

Dead Coin Battery

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

If the key fob was exposed to water (such as rain or soapy tap water) it is recommended to remove and clean the chip with an electronic cleaner or isopropylethanol before installing a brand new battery. The chip is sensitive to moisture and can be permanently damaged. If the key fob is still not working after replacing the battery, it might 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 stopped working suddenly the receiver module could be experiencing a problem. The receiver module receives radio frequency signals from the remote keyfob and converts them into electrical commands that are then processed by other modules inside the car.

The key fob is sealed by rubber to block water from getting into the electronic chip. If you submerge the key fob in 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 in the event that your key fob isn't working after this, then you'll need to purchase a replacement.

If the keys are connected, but the receiver module is malfunctioning You can try to restart all the electronics on board by disconnecting the battery with 12 volts for a few minutes. Connect seat key replacement in reverse (negative cable to positive first). This will reset all electronic components onboard and restore their functionality.

A malfunctioning electronic chip

The key fob comes with a chip that transmits the signal from the key to the receiver module every time the key is used. If the signal doesn't match the one stored by the car the immobilizer is able to shut off the engine and prevent the vehicle from starting. However, if the fob isn't functioning and you are not able to reprogram it, it could be due to a defective chip.

The chip inside the key fob could need change to make it work again. This can be done by removing the key fob from its housing, and using pins or needles to connect with each metal retaining clip. You will need to replace these if they are damaged or corroded. Make sure that the replacement batteries are of the same size, voltage, and specification as the original.
