Seat Alhambra Key Problems

Seat's jumbo family MPV is one of the best in the market in terms of retaining resale value. And with a new model now on sale it's even better.

There are a myriad of reasons why the key fob could not function correctly, including dead battery, damage to the receiver module, water problems or signal interference. This article will walk you through the steps needed to make it work again.

Water Damage

If your key fob for the seat alhambra withstands a wash cycle or a dip in an ocean or a pool then it has a waterproof chip. But don't do this often, as prolonged exposure to water can increase the likelihood of the key fob becoming damaged. If your key fob ceases to functioning after being exposed to rain or clean tap water, take out the battery and wipe the electronic component with a towel. Dry it 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 you have tried a new button cell battery and the key fob still doesn't lock or unlock then it's likely that the receiver module has discovered a problem. It is a relatively easy and inexpensive fix. You can disconnect the 12 volt battery for a few minutes (first remove the negative cable, then press the horn numerous times) to eliminate any remaining electricity. Then connect it in reverse. Positive first followed by negative.

ESP Warning Light If the ESP warning symbol flashes this is normal and signifies that the car is travelling over terrain in which the traction between the road surface and the tyres isn't ideal, like gravel, snow or a lot of surface water. If the ESP light is constantly on, it indicates that there is a fault in the system. This can be identified with a iCarsoft i908 seat OBD code reader kit. It will provide the full description of the problem.

Dead Coin Battery

One of the most common reasons for the seat alhambra key to stop working is a dead coin battery. The key fob is powered by a small button-cell battery. Replace it with a new battery that has the same size, voltage and specifications as the original. If you're replacing your battery, be sure to remove all metal clips from the back of the key fob. Also ensure that the contacts are free of corrosion.

If the key fob was exposed to water (such as soapy or rain tap water), it is recommended that you remove and clean the chip with an electronic cleaner or isopropylethanol before installing a new battery. The chip is sensitive to moisture and could be permanently damaged. If the key fob still does not work after replacing the battery, it might be necessary to replace the key fob.

Faulty Receiver Module

If your key fob has stopped working after replacing the battery but it didn't function, or stopped working abruptly the receiver module could have developed a problem. The receiver module takes the radio frequency signals from your remote keyfob, and transforms them into electrical signals that are then followed by other modules within the car.

If the receiver module has developed a fault that prevents it from responding to any of the commands issued by your remote key fob. In this instance you'll have to visit a dealer to reprogram your key fob and a new receiver module.

You can try cleaning the chip by rubbing it with isopropyl alcohol or electronic cleaner, but in the event that your key fob does not work after this, then you'll need to purchase a replacement.

If the keys have been paired but the receiver module has developed a fault, you may try to restart all of the onboard electronics by disconnecting the 12 volt battery for a few minutes. Connect the battery in reverse (negative cable to positive first). This will reset the on-board electronic and restore their functionality.

Faulty Electronic Chip


The key fob is equipped with a small chip that transmits a signal from the key to 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 is disabled and stop the car from starting. However, if the key fob isn't functioning and you are unable to reprogram it the issue could be due to a defective chip.

The chip in the key fob may need to be replaced 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 contact each metal retaining clip. If these clips are damaged or damaged, you'll have to replace them to allow the remote control to function. Make sure that any replacement batteries are the same voltage, size and specifications as the original one.
