Seat Alhambra Key Problems
Seat's jumbo MPV range is among the top models in its class when it comes down to resale value. With a brand new model on sale, the Jumbo family MPV is more impressive.
There are many reasons why the key fob might not work as expected, including an unresponsive coin battery or damage to the receiver module, or signal interference. This article will walk you through the steps needed to get it working again.
Water Damage
If your seat alhambra key fob is able to withstand the wash cycle or a bath in the ocean or pool then it is likely to have an amazing waterproof chip. However, don't make this a habit because prolonged exposure to water increases the chance of the key fob becoming damaged. If seat key working after exposure to clean tap water or rain, simply take out the battery, clean the electronic component with paper towel and let it dry completely before putting the battery back into. If the key fob has been exposed to salty or soapy water and salty water, it is recommended you clean the chip using isopropyl or an electronic cleaner.
Faulty Receiver Module
If the key fob will not lock or unlock even after you've replaced the battery for the button It is possible that the receiver module is suffering from a fault. It's a simple and inexpensive fix. You can unplug the 12 volt battery for a few minutes (first remove the negative cable, then press the horn numerous times) in order to drain any remaining power. Then connect it in reverse. Positive 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 aren't as good, such as snow, gravel or lots of surface water. If the ESP warning light is constantly illuminated it indicates that there is a glitch in the system. It should be detected using an iCarsoft i908 Seat OBD Code Reader kit which will give you a specific fault description.
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 a small button-cell battery. Replace it with a brand new battery that has the same dimensions, voltage and specs as the original. If you are replacing the battery, ensure that you remove all metal clips from the back of the key fob and ensure that 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 with an electronic cleaner or isopropylethanol prior to installing a new battery. The chip is sensitive to moisture and may be permanently damaged. If the key fob still not working after replacing the battery, it may be necessary to replace the entire key fob.
Faulty Receiver Module
If your key fob has stopped working after replacing the battery but it did not work, or if it stopped working abruptly, your receiver module could have experienced a malfunction. The receiver module is able to receive radio frequency signals from the remote keyfob and transforms them into electrical signals which are then used by other modules inside the car.
If the receiver module has developed a fault that prevents it from responding to any of the commands transmitted by your remote key fob. In this situation it is necessary for a dealer to reprogramme your key fob and install an additional receiver.
The key fob is covered with rubber to prevent water from leaking into the electronic chip. However, if you submerge the key fob in salted or soapy ocean water, the chip inside could be damaged. If your key fob isn't able to work, you can 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 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 followed by positive). This will reset the onboard electronic circuit and restore their functionality.
Faulty electronic chip
The key fob is outfitted with a small chip that transmits the signal from the key to the receiver module each time the key is used. If the signal received does not match the one stored by the car the immobilizer will stop the engine and stop the vehicle from starting. If, however, the key fob isn't working and you can't reprogram it this could be due to a malfunctioning chip.
The chip inside the key fob could need change in order to get it working again. This can be accomplished by getting the key fob removed from its housing, and using a needle or pin to connect with each metal retaining clip. If these clips are damaged or damaged, you'll need to replace them to allow the remote control to work. Make sure that the replacement batteries are of the same size, voltage and specification as the original one.
The Seat Alhambra is an attractive and well-designed model but like any other car it may encounter issues with specific components or equipment. For example there are owners who have had problems with the climate control system, which may be faulty and get stuck in a particular setting. The infotainment system can also malfunction and cause freezes on the screens.
