The History Of Seat Keys Replacement In 10 Milestones
Seat Alhambra Key Problems
Seat's jumbo MPV family is among the top models in its class when it comes to resales values. And with a new generation model available it's even more impressive.
There are a number of reasons why the key fob might not function correctly, including dead battery or damage to the receiver module, water problems or signal interference. This article will walk you through the steps necessary to fix it.
If your seat alhambra key fob can withstand washing cycles or a bath in the pool or ocean then it probably has an incredible waterproof chip, but do not make it a habit as exposure to excessive water increases the chance of the key fob being damaged. If your key fob ceases to working after exposure to rain or clean tap water, take out the battery and wipe the electronic component with a towel. Let it dry completely before replacing the battery. If the key fob was exposed to salty or soapy water and salty water, it is recommended you clean the chip with isopropyl or electronic cleaner.
Faulty Receiver Module
If the key fob will not lock or unlock after having replaced the button cell battery it could be that the receiver module has a fault. The good news is that it is a fairly easy repair that is inexpensive, you can disconnect the 12 volt battery for a few minutes (first take off the negative cable and then press the horn button a few times) to remove any remaining electricity and then reconnect it in reverse order e.g. Positive cable first and then negative.
ESP Warning Light - If the ESP warning light flashes, it is normal and means that the vehicle is driving over terrain in which the traction between the road surface and the tyres isn't optimal, like snow, gravel or lots of surface water. If the ESP light is constantly on, it indicates that there is a problem with the system. It is possible to identify the problem by using an iCarsoft i908 seat OBD code reader kit. It will provide a detailed 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 contains an insignificant button cell battery that is able to keep it powered. It should be replaced by a new battery that has identical in size, voltage and specifications as the original. If you are replacing the battery, be sure to remove all metal clips from the back of the key fob. Also make sure the contacts are 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 using isopropyl alcohol or an electronic cleaner prior to putting in the new battery. The chip can be permanently damaged by moisture. If the key fob still isn't working after replacing the battery it could be necessary to replace the key fob.
Faulty Receiver Module
If your key fob stopped functioning after replacing the battery, but it did not work, or if it stopped working suddenly the receiver module could have encountered a problem. The receiver module takes the radio frequency signals from your remote keyfob and converts them into electrical commands which are then used by other modules in the car.
If the receiver module has suffered a malfunction and is unable to respond to any of the commands sent by your remote key fob. In this scenario you will require a dealer to reprogramme your key fob as well as install the new receiver.
The key fob is fitted with rubber seals that block water from getting into the electronic chip inside. If you immerse the key fob into soapy or salty water, it could cause damage to the chip. If your key fob won't work, try cleaning the chip with isopropyl or an electronic cleaner.
If the keys are paired but the receiver module has developed a fault, you can try rebooting all of the electronics on board by removing the 12 volt battery for a short period of time. Then reconnect the battery in reverse order (negative cable first followed by positive). This resets all the electronic components onboard and restore their functionality.
Faulty electronic chip
The key fob contains a small electronic chip that transmits a message to the receiver module each time the key is used. If the signal doesn't match the one stored by the car, the immobilizer will disable the engine and stop the vehicle from starting. However, if the key fob isn't functioning and you cannot reprogram it the issue could be due to a faulty chip.
The chip in the key fob isn't an indefinite part of the device and could need to be replaced to get it working again. This can be done by getting the key fob removed from its housing, and using pins or needles to contact each metal retaining clip. If these clips are damaged or damaged, you'll require replacement to allow the remote control to function. Make sure that the replacement batteries have the same voltage, size, and specification as the original.
