Seat Alhambra Key Problems

Seat's jumbo MPV range is among the best in its class when it comes to resale values. With a new model currently on sale the jumbo family MPV is even better.

There are many reasons the key fob could not function properly, such as an inoperative coin battery or water damage to the receiver module or signal interference. This article will walk you through the steps to get it working again.

Water Damage

If your seat alhambra keyfob is able to survive a wash cycle or a bath in the ocean or pool it's likely to have an amazing waterproof chip but do not make it a habit because prolonged exposure to water increases the chance of the key fob becoming damaged. If made a post stops functioning after being exposed to rain or clean tap water, you should remove the battery and clean the electronic component using a paper towel. Let it dry completely before replacing the battery. If the key fob was exposed to soapy or salty water, it is recommended that you clean the chip using isopropyl or electronic cleaner.

Faulty Receiver Module

If the key fob does not lock or unlock even after you've replaced the button cell battery It is possible that the receiver module has an issue. It's a relatively simple and inexpensive fix. You can unplug the 12 volt battery for a few minutes (first remove the negative cable and then press the horn numerous times) to eliminate any remaining electricity. Then reconnect it in reverse. Positive cable first, then negative.

ESP Warning Light If the ESP warning light is flashing, this is normal and means that the vehicle is driving on terrains where the traction of the road surface and the tyres aren't as good, such as gravel, snow or a lot of surface water. If the ESP warning light continues to be flashing, it means there is an error within the system. This can be detected with a iCarsoft i908 Seat OBD Code Reader kit that will provide a precise fault description.

Dead Coin Battery

A dead battery for the coin is among the most common causes 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 with a brand new one that is the same size, voltage, and specification as the original. When replacing the battery on the key fob remove the metal clips and make sure that the contacts on the key fob are clean and corrosion-free.

If the key fob has been exposed water, such as rain or soapy water, it's recommended that you remove the battery and clean the electronic chip with alcohol isopropyl or an electronic cleaner prior to installing the new battery. The chip is sensitive to moisture and may be permanently damaged. If the key fob still doesn't work after replacing the battery it could be necessary to replace the key fob.

Faulty Receiver Module

If your key fob has stopped working after you replaced the battery, but it didn't help, or it suddenly stopped working out of the blue, then your receiver module may have developed an issue. The receiver module receives the radio frequency signals from the remote keyfob and transforms them into electrical signals that are then followed by other modules within the car.

If the receiver module has a problem it will not take any commands from your remote key fob. In this scenario, you will have to visit a dealer for reprogramming of your key fob and a new receiver module.

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 salted or soapy water it could cause damage to the chip. You can try cleaning the chip by applying isopropyl alcohol or electronic cleaner, however if your key fob still does not work after this, then you'll need to buy a new one.

If the keys are in a pair but the receiver module has developed a fault, you can try to reboot all electronics on board by disconnecting the battery that is 12 volts for a few minutes. Then, reconnect the battery in reverse order (negative cable first followed by positive). This resets all the electronics onboard and will bring them back to their original functionality.

Electronic Chip Faulty

The key fob has tiny electronic chips which transmits a signal the receiver module every time the key is used. If this signal does not match the one stored by the car the immobilizer is able to shut off the engine and stop the vehicle from starting. If the key fob doesn't work and you are unable to reprogram it, this could be because of an incompatible microchip.

The chip inside the key fob isn't permanent to the device and may need to be replaced in order to make it work again. The best way to do this is to remove the key from its housing and using a pin or needle to connect with each of the metal retaining clips. You will have to replace them in the event of damage or damaged or corroded. Make sure that any replacement batteries are of the same voltage, size and specifications as the original.
