The Reasons Seat Keys Replacement Could Be Your Next Big Obsession
Seat's jumbo family MPV is among the top in its class when it comes to retaining resale value. With a new generation model available, it's better than ever.
There are a number of reasons that the key fob could not function correctly, including dead battery, damage to the receiver module, water issues, or signal interference. This article will walk you through the steps needed to get it back to working.
Water Damage
If your key fob for the seat alhambra withstands washing cycles or dip in the ocean or a pool, then it's got a waterproof chip. But be careful not to do this often as excessive exposure to water increases chances of the key fob becoming damaged. If the key fob ceases to functioning after exposure to clean water from the tap or rain, then just remove the battery, wipe the electronic component with paper towel and let it dry completely before putting the battery back into. If you are exposed to soapy or salty water it is recommended to clean the chip with isopropyl alcohol or an electronic cleaner prior to trying to put the battery back in.
Faulty Receiver Module
If you've tried the battery of a button cell and the key fob still isn't locked or unlocking, it's likely that your receiver module has been faulty. It's a simple and cheap fix. You can remove the battery that is 12 volts for a few minutes (first remove the negative cable and then press the horn several times) to eliminate any remaining electricity. Then reconnect it in reverse. Positive first and then negative.
ESP Warning Light – If the ESP symbol is flashing, this is normal. It is a sign that you are driving on terrain that has poor traction. This could be due to gravel, snow or surface water. If the ESP light is always on, it is a sign that there is a problem with the system. This can be diagnosed with a iCarsoft i908 seat OBD code reader kit. It will give you detailed information about the fault.
Dead Coin Battery
One of the most frequent reasons for the seat alhambra keys to stop working is a dead battery. The key fob is powered by a small button-cell battery. Replace it with a brand new battery that has the exact voltage, size and specification as the original. If you're replacing the battery, be sure to remove all metal retaining clips from the back of the key fob and make sure the contacts are free of corrosion.
If the key fob was exposed to water (such as rain or soapy tap water) it is recommended that you remove and clean the chip using an electronic cleaner or isopropyl ethanol before installing a new battery. The chip may be permanently damaged by water. 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 functioning after replacing the battery, but it didn't function, or stopped working in a sudden manner your receiver module might have encountered a problem. The receiver module is able to receive radio frequency signals from your remote keyfob and converts them into electrical commands that are then followed by other modules in the car.
If the receiver module is defective it will not be able to accept any commands from your remote key fob. In this situation you'll need to go to a dealer to reprogram the key fob, and also a new receiver module.
The key fob comes with rubber seals to prevent water from entering the chip inside. If you immerse the key fob in salted or soapy ocean water, the chips inside may be damaged. You can attempt to clean the chip by rubbing it with isopropyl alcohol or electronic cleaner, but if your key fob still does not work after this, you'll have to purchase a new one.
If the keys are connected but the receiver module has developed a fault, you may try to restart all of the electronics on board by disconnecting the battery with 12 volts for a short period of time. Then, reconnect the battery in reverse order (negative cable first before positive). This will reset the on-board electronic circuits and restore their functionality.
Faulty electronic chip
The key fob is outfitted with a tiny chip which transmits an indication from the key to the receiver module every time the key is used. If the signal doesn't match that stored by the car the immobilizer will shut down the engine and prevent the vehicle from starting. However, if the fob isn't working, and you are unable to reprogram it the issue could be due to a defective chip.
The chip in the key fob isn't an indefinite part of the device and may need to be replaced in order to make it work again. The most effective method for doing this is by removing the key from its housing and using a pin or needle to connect with each of the retaining clips made of steel. If these clips are damaged or broken, you will need to replace them to allow the remote control to work. Make sure that any replacement batteries are the same size, voltage and specifications as the original one.
