Water Damage

If your key fob for the seat alhambra withstands the wash cycle or dip in the ocean or a pool then it's equipped with a waterproof chip.

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

Faulty Receiver Module

The positive side is that this is a fairly easy repair that is inexpensive, you can simply disconnect the 12 volt battery for just a few minutes (first take off the negative cable and then press the horn button a few times) to remove any remaining electric current, then reconnect it in reverse order e.g. Positive first, then negative.

ESP Warning Light - If the ESP warning light flashes, it is normal and means that the car is traveling on terrains where the traction of the road surface and tyres isn't ideal, like gravel, snow or a lot of surface water. If the ESP light is always flashing, it is a sign there is a problem in the system. It is possible to identify the problem by using an iCarsoft i908 seat keys OBD code reader kit.

Dead Coin Battery

A dead battery for the coin is among the most common reasons for the keys for the seat key cover to cease to function. The key fob comes with a small button cell battery which keeps it powered. It should be replaced with a new one that has the same size, voltage and specifications as the original. If you're replacing your battery, be sure to remove all metal 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 was exposed to water, like soapy or rain it is recommended to remove the battery and clean the electronic chip with isopropyl alcohol or an electronic cleaner prior to installing the new battery. The chip may be permanently damaged by moisture. If the key fob is still not working after replacing the battery, it could be necessary to replace the entire key fob.

Faulty Receiver Module

If your key fob has stopped working after replacing the battery, but it didn't work, or stopped working suddenly, your receiver module could have encountered a problem. The receiver module is able to receive radio frequency signals from your remote keyfob and converts them into electrical commands which are then acted upon by other modules within the car.

If the receiver module has developed a fault it will not respond to any of the commands transmitted by your remote key fob. In this scenario you'll be required to visit a service for reprogramming your key fob and a new receiver module.

The key fob is encased with rubber to stop water from leaking into the electronic chip. If you dip the key fob into soapy or salty water, it could cause damage to the chip. If your key fob doesn't work, you could try cleaning the chip using isopropyl or electronic cleaner.

If the keys have been paired but the receiver module has developed a fault, you can try rebooting all of the onboard electronics by removing the battery with 12 volts for a short period of time. Then reconnect the battery in reverse order (negative cable first and then positive). This will reset all the electronics onboard and will restore their functionality.

Faulty Electronic Chip

The key fob is fitted with a tiny chip which transmits an indication from the key seat to the receiver module every time the key is used. If this signal does not match the one recorded by the car the immobilizer will stop the engine and prevent the vehicle from starting. If the key fob does not work and you are unable to reprogram it, this could be because of an incompatible microchip.

The chip inside the key fob isn't an indefinite part of the device, and might need to be replaced to get it to work again. This can be done by taking the key fob out of its case, and using a needle or pin to make contact with each metal retaining clip. If they are corroded or broken, you will have to replace them in order for the remote control to work. Make sure that the replacement batteries are the same size, voltage, and specification as the original.
