7 Things You've Never Known About Seat Keys Replacement
Seat Alhambra Key Problems
Seat's MPV jumbo family is among the best in its class when it comes down to resale value. And with a brand new model now on sale, it's even better.
There are a number of reasons why the key fob might not work properly, including a dead battery or damage to the receiver module, water issues or signal interference. This article will walk you through the steps to make it work again.
Water Damage
If your seat alhambra key fob survives an wash cycle or bath in the pool or ocean then it is likely to have an incredible waterproof chip, but do not make it a habit as exposure to excessive water increases the chance of the key fob becoming damaged. If your key fob ceases to functioning after exposure to rain or clean tap water, take out the battery and clean the electronic component using a paper towel. Dry it completely before replacing the battery. If the key fob was exposed to soapy or salty water and salty water, it is recommended you clean the chip with isopropyl or an electronic cleaner.
Faulty Receiver Module
If you have tried the battery of a button cell and the key fob still doesn't lock or unlock then it is likely that the receiver module has developed a fault. It's a relatively simple and cost-effective fix. You can unplug the 12 volt battery for a few minutes (first remove negative cable, then press the horn several times) to drain any remaining power. Then, reconnect it in reverse. Positive first followed by negative.
ESP Warning Light If the ESP warning light is flashing, this is normal and indicates that the car is traveling through terrain in which the traction between the road surface and tyres is not ideal like snow, gravel or lots of surface water. If the ESP light is constantly on, it indicates that there is a flaw in the system. This can be diagnosed by using an iCarsoft i908 seat OBD code reader kit. It will give you detailed information about the fault.
Dead Coin Battery
One of the most common reasons for the seat alhambra keys to stop working is a dead battery. The key fob is powered by a tiny button-cell battery. content is recommended to replace it by a new battery that has identical in size, voltage and specifications as the original. When replacing the battery on the key fob remove all metal clips and ensure that the contacts on the key fob are clean and 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 with isopropyl alcohol or a electronic cleaner before putting in the new battery. The chip is susceptible to moisture and could be permanently damaged. If the key fob does not work after replacing the battery it may be necessary for you to replace the key fob.
Faulty Receiver Module
If your key fob was not working after replacing the battery, but it didn't perform, or stopped working suddenly the receiver module may have encountered a problem. The receiver module takes the radio frequency signals from your key fob's remote and transforms them into electrical signals that are then followed by other modules within the car.
If the receiver module is faulty it will not be able to accept any commands from your remote key fob. In this case you will require a dealer to reprogram your key fob as well as install an entirely new receiver.
The key fob features rubber seals to prevent water from entering the electronic chip inside. However, if you submerge the key fob in soapy water or salty ocean water, the chips inside may be damaged. You can try cleaning the chip by rubbing it with isopropyl alcohol or electronic cleaner, however if your key fob still does not work after this, you'll have to buy a new one.
If the keys are paired but the receiver module has developed a fault you can try restarting all the on-board electronics by disconnecting the battery at 12 volts for a short period of time. Connect the battery in reverse (negative cable to positive first). This will reset the on-board electronic and restore their functionality.
Faulty Electronic Chip
The key fob is equipped with an electronic chip that transmits a message to the receiver module whenever the key is used. If the signal isn't in line with the one the car has stored the immobilizer will be disabled and stop the car from starting. If the key fob won't function and you are not able to reprogram it, this could be due to an incompatible microchip.
The chip in the key fob isn't permanent to the device, and might need to be replaced to function again. The best way to do this is by removing the key from its housing and using a pin needle to get into contact with each of the metal clips that hold it. If they are corroded or broken, you will require replacement in order for the remote control to work. Make sure that any replacement batteries are of the same size, voltage and specification as the original one.
