Seat Alhambra Key Problems

Seat's jumbo MPV range is among the top in its class when it comes to resale value. And with a new model on sale it's even better.

There are a myriad of reasons why the key fob might not function properly, including a dead battery water damage, receiver module issues, or signal interference. This article will walk you through the steps to get it working.

Water Damage

If your seat alhambra key fob is able to withstand the wash cycle or a bath in the pool or ocean then it probably has an incredible waterproof chip, but do not make it a habit because exposure to water in excess increases the chance of the key fob becoming damaged. If your key fob ceases to functioning after exposure to rain or clean tap water, remove the battery and clean the electronic component with a paper towel. Dry it completely before replacing the battery. If you are exposed to salt or soapy water it is recommended to wash the chip with isopropyl alcohol or an electronic cleaner before attempting to put the battery back in.

Faulty Receiver Module

If you have tried a new battery for a button and the key fob cannot be locked or unlocked, it is likely that the receiver module has developed a fault. The positive side is that this is an easy and inexpensive repair, you can just remove the battery 12 volts for several minutes (first remove the negative cable then press the horn button a few times) to drain any residual electricity and then reconnect it in reverse order e.g. positive cable first, then negative cable later.

ESP Warning Light - If the ESP warning light flashes, this is normal and indicates that the vehicle is driving 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 always on, it means that there is a flaw in the system. It can be detected with a iCarsoft i908 seat ibiza car key replacement OBD code reader kit. It will give you detailed information about the fault.

Dead Coin Battery

A dead battery for the coin is among the most common reasons for the seat alhambra keys to stop working. The key fob is powered by a small button-cell battery. It is recommended to replace it by a new battery that has the same voltage, size, and specification as the original. When replacing the battery on the key fob remove the metal clips and make sure that the contacts of the key fob are clean and free of corrosion.

If the key fob was exposed to water (such as 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 is sensitive to moisture and could be permanently damaged. 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 stopped functioning after replacing the battery but it didn't work, or stopped working abruptly the receiver module may have encountered a problem. The receiver module receives radio frequency signals from your key fob's remote and converts them into electrical commands which are then used by other modules in the car.

If the receiver module is faulty and is not able to take any commands from your remote key fob. In this case, a dealer will need to reprogram your key fob and install an additional receiver.

The key fob has been sealed by rubber to block water from leaking into the electronic chip. However, if you submerge your key fob into soapy water or salty ocean water, the chip inside may be damaged. If your key fob doesn't function, you can try cleaning the chip with isopropyl or an electronic cleaner.

If the keys are linked, but the receiver module is not working You can try to restart all the electronics in the board by disconnecting the battery that is 12 volts for a couple of minutes. Then reconnect the battery in reverse order (negative cable first followed by positive). This will reset all electronic components onboard and bring them back to their original functionality.

Electronic Chip Faulty

The key fob is equipped with tiny electronic chips which transmits a signal the receiver module each time the key is used. If the signal isn't in line with the one that the car has stored the immobilizer will turn off and stop the car from starting. If, however, the key fob isn't working, and you are unable to reprogram it then it could be due to a faulty chip.

The chip in the key fob might need to be altered in order to make it function properly. The most effective method for doing this is by removing the key from its housing and using a pin needle to make contact with each of the retaining clips made of steel. You will require replacement in the event of damage or corrosion-prone. Make sure that the replacement batteries are the same size, voltage and specifications as the original one.

The Seat Alhambra is an attractive and well-designed model but like any other car, it can sometimes experience issues with particular components or equipment. For example there are owners who have had problems with the automatic climate control system, which could be faulty and get stuck in one particular setting. Similarly, the infotainment system has also been known to malfunction and freeze screens.
